Browser Collectors

Overview

The AIDR browser collector is a lightweight browser extension that you install on managed endpoints to capture AI interactions in supported browsers and send data to AIDR for visibility and policy enforcement.

You can use the AIDR browser collector to monitor and analyze employee use of web-based AI tools like ChatGPT, Claude, Gemini, and other supported providers in managed enterprise environments. Based on the analysis, you can apply policies to protect your organization from risks identified in user inputs.

Requirements

To start monitoring employee AI usage using browser collectors, ensure you have:

• A customer account in one of the supported CrowdStrike clouds:
  • US-1
  • US-2
  • EU-1
• AIDR for Workforce Falcon subscription
• AIDR Admin role explicitly assigned to your Falcon user account for the current customer
• Supported operating system:
  • Windows
  • macOS
• Supported browsers:
  • Google Chrome
  • Microsoft Edge
• Admin privileges on the user machine(s), necessary for updating system-level configuration:
  • Registry on Windows
  • Configuration profile on macOS

Register browser collector

In the Falcon console, click Open menu (☰) and go to

AI detection and response > Collectors .

1. On the Collectors page, click + Collector.

2. Choose Browser as the collector type, then select a browser option and click Next.

3. On the Add a Collector screen:

   • Collector Name - Enter a descriptive name for the collector to appear in dashboards and reports.
   • Logging - Select whether to log incoming (prompt) data and model responses, or only metadata submitted to AIDR.
   • Policy (optional) - Assign a policy to apply to incoming data and model responses.

   Use the assigned policy to determine which detections run on data sent to AIDR. Policies define rules for detecting malicious activity, sensitive data exposure, topic violations, and other risks in AI interactions.

   • You can select an existing policy available for this collector type or create new policies on the

     Policies page.

     The selected policy name appears under the dropdown. Once collector registration is saved, this label becomes a link to the corresponding policy page.

   • You can also select No Policy, Log Only. When no policy is assigned, activity is recorded for visibility and analysis without applying detection rules.

4. In the Sites section, configure how policy rules apply to each AI provider domain.

   The Sites section lists supported AI provider websites that the extension can monitor. Each site can be set to one of the following modes to use or override the collector-level policy rules:

   • Use Policy (default) - Apply the collector's policy rules to this site. User prompts and AI system responses are sent to AIDR for analysis and logging. User prompts may be blocked or transformed. To see how your collector policy rules are defined, find the policy you assigned to your collector on the Policies page in the AIDR console.
   • Monitor Only - Apply the collector's policy rules to this site in report-only mode. User prompts and AI system responses are sent to AIDR for analysis and logging. The user experience isn't affected.
   • Discovery - Skip sending AI traffic to AIDR. Only record that users visited the site.
   • Disabled - Ignore this site entirely. No monitoring or logging is done.

5. Click Save to complete collector registration.

tip:

Start with one of the policies provided in AIDR by default.

• No policy, Log Only
  • Record user activity.
  • Skip risk detection.
• Browser Monitor
  • Record user activity.
  • Detect risks in AI traffic using pre-configured detectors and save event logs.
• Browser Protect
  • Record user activity.
  • Detect risks in AI traffic using pre-configured detectors and save event logs.
  • Apply pre-configured policy actions to the user's input.

You can change your policy configuration or clone it and define a custom policy.

note:

Browser collector policy output rules always run in Report Only Mode and won't modify AI responses shown to users, regardless of the selected policy.

This opens the collector details page, where you can:

• Copy credentials and AIDR base URL from the Config tab to communicate with AIDR APIs.
• View installation instructions for the collector type on the Install tab.
• Update the collector name, its logging preference, and reassign the policy.
• Follow the policy link to view the policy details.
• View the collector configuration activity logs.

If you need to return to the collector details page later, select your collector from the list on the Collectors page.

Deploy collector

To deploy a browser collector, you must:

• Install the browser extension.
• Save AIDR collector configuration in the extension's Managed storage.

Managed storage

All deployment methods achieve the same result - populating the browser extension's Managed storage with the values it needs to connect to AIDR.

Chrome Enterprise pushes configuration via cloud policy directly to the extension's managed storage in enrolled Google Chrome browsers, bypassing OS-level settings.

Other methods configure the system through configuration profiles (macOS) or registry entries (Windows).

Configuration fields

• Required fields:

  • registrationIdentity - Encoded credentials the extension uses to authenticate with the AIDR service and obtain an authorization token
  • urlTemplate - AIDR API base URL

  You can find collector-specific values for registrationIdentity and urlTemplate under the Install tab on the collector details page in the AIDR console. Configuration files and templates available on the Install tab are pre-populated with these values.

• Optional user identity fields that appear in AIDR event logs:

  • userId - User identifier (for example, email address). Appears in AIDR logs and findings.
  • userFullName - User's display name. Appears in AIDR logs and findings.
  note:

  Downloaded configuration files are pre-populated with values from the current session:

  • urlTemplate - Set to the AIDR API URL for your CrowdStrike cloud.
  • registrationIdentity - Set to collector-specific credentials.
  • userId and userFullName - Set to the current AIDR console user's information.

  If you distribute the configuration file to other users, update the userId and userFullName fields to match the target user's identity. In production deployments, you typically set these values dynamically per user using variables in endpoint management tools or scripts.

tip:

To check extension managed storage in Chrome and Edge:

1. In your browser address bar, go to chrome://extensions (or edge://extensions).
2. Enable Developer mode.
3. In the AIDR extension card, click service_worker.
4. In the DevTools console for the background service worker, switch to the Application tab.
5. Expand Extension storage and click Managed.
6. Verify the storage keys are populated.

System paths

JAMF, Intune, and Self-Service apply extension configuration through OS-level settings. You can verify these settings at the following OS and browser-specific locations:

• macOS - Managed preference plist files

  Google Chrome

  plutil -p /Library/Managed\ Preferences/<user>/com.google.Chrome.extensions.folndgmoekgkipoolphnkclopeopkecc.plist
  Microsoft Edge

  plutil -p /Library/Managed\ Preferences/<user>/com.microsoft.Edge.extensions.folndgmoekgkipoolphnkclopeopkecc.plist
  Example configuration

  {
    ...
    "registrationIdentity" => "eyJzIj...YiOjF9"
    "urlTemplate" => "https://api.crowdstrike.com/aidr/aiguard"
    "userFullName" => "<user-full-name>"
    "userId" => "<user-id>"
  }

• Windows - Registry keys

  Google Chrome (PowerShell)

  Get-ItemProperty -Path "HKLM:\Software\Policies\Google\Chrome\3rdparty\extensions\folndgmoekgkipoolphnkclopeopkecc\policy"
  Microsoft Edge (PowerShell)

  Get-ItemProperty -Path "HKLM:\SOFTWARE\Policies\Microsoft\Edge\3rdparty\extensions\folndgmoekgkipoolphnkclopeopkecc\policy"
  Example configuration

  urlTemplate          : https://api.crowdstrike.com/aidr/aiguard
  registrationIdentity : eyJzIj...I6MX0=
  userId               : <user-id>
  userFullName         : <user-full-name>
  ...

Select Install option

On the collector details page, switch to the Install tab, which provides instructions, links, and templates for common deployment methods.

• JAMF - Use Apple-native Configuration Profiles to enforce extension deployment and system-level settings on macOS.
• Microsoft Intune - Deploy extensions and configuration profiles across Windows and macOS managed endpoints.
• Chrome Enterprise (Google Chrome only) - Use Chrome Enterprise to enroll browsers into the Google Admin console for centralized cloud-based policy management.

• Self-Service - Install the extension and apply a configuration profile on a single machine to quickly evaluate and test the collector.

Chrome Enterprise (Google Chrome only)

You can use Chrome Enterprise Cloud Management to enable centralized installation and configuration across all managed Chrome browsers in your organization.

Install extension

Learn how you can enroll cloud-managed Chrome browsers and browser profiles in the Cloud-managed Chrome browser documentation.

Configure extension

With user browsers and profiles enrolled, in your Google Admin console :

1. Click the Main menu (☰) icon and navigate to Chrome browser > Apps & extensions and add the AIDR Chrome browser extension:

   1. Select or create an Organizational Unit (OU).

   2. Click the Users & browsers tab.

   3. Hover over the + icon and select Add Chrome app or extension by ID.

   4. In the Add Chrome app or extension by ID dialog, enter Extension ID, which you can find on the Install tab in the AIDR console:

      folndgmoekgkipoolphnkclopeopkecc

   5. Click SAVE to save your changes and close the dialog.

2. Select the added extension in the app list. Under Policy for extensions, paste the Extension Policy JSON copied from the Install tab in the AIDR console.

   This policy configuration authenticates the extension with your AIDR service and enables communication with AIDR APIs. When you use the Copy button, the JSON is populated with the correct credentials and AIDR base URL from your collector registration.

3. Select an Installation policy.

   For example, choose Force install + pin to browser toolbar to automatically deploy the extension to all enrolled user devices in the OU and pin it for visibility and user awareness.

4. Click SAVE in the top right corner of the screen.

note:

Chrome Enterprise policies can't dynamically populate user identity fields:

• userId
• userFullName

To enable user-level tracking in AIDR event logs, configure these fields on each user's endpoint using an endpoint management tool (JAMF, Intune, or similar). Deploy a managed preference profile or registry entry for the extension at the following system paths:

• macOS preference domain:
  • com.google.Chrome.extensions.folndgmoekgkipoolphnkclopeopkecc
• Windows registry path:
  • HKLM:\Software\Policies\Google\Chrome\3rdparty\extensions\folndgmoekgkipoolphnkclopeopkecc\policy

See Managed storage section for additional details.

tip:

The extension DevTools might not be accessible by default, especially if you force-install the extension.

If you plan to debug the extension on target machines, in the Google Admin console:

1. Go to Devices > Chrome > Settings > Developer tools availability.
2. Set Developer tools availability to Always allow use of built-in developer tools.
3. Click Save.

Self-Service (testing)

Select the Self-Service option to quickly evaluate the collector on your own machine before deploying it at scale. This option:

• Introduces the key browser collector deployment steps
• Requires no management tools
• Lets you perform both installation and configuration steps manually on your machine
• Describes the extension deployment statuses and functionality, also applicable to production deployments using enterprise management tools

Self-service limitations:

Self-service deployment is intended for testing and evaluation purposes. It isn't a supported option for production deployments.

The first time you select this option, you must acknowledge these limitations in a confirmation dialog before proceeding.

Install extension

The AIDR collector for Google Chrome and Microsoft Edge is a Chrome extension in the Chrome Web Store.

1. Use the Get the AIDR Extension link to open the extension page in Chrome Web Store.
2. Click Add to Chrome (or Add to Edge) to install the extension in your browser.

Once installed, the extension will appear under Extensions in your browser toolbar (the puzzle piece icon in the top-right corner) and in the list of installed extensions at chrome://extensions (or edge://extensions).

Configure extension

1. Return to the Install tab and download the configuration file for your operating system:

   • macOS - AIDR Chrome Profile (.mobileconfig)
   • Windows - AIDR Windows registry file (.reg)

   This file contains the collector instance configuration, including credentials to authenticate the extension with the AIDR service.

2. Apply the configuration:

   • macOS

     1. Double-click the downloaded configuration profile (.mobileconfig), then activate it in System Settings > General > Device Management > Profiles. If a previous profile for this extension exists, remove it from this location first.

        The exact path may vary depending on your macOS version.

   • Windows - Double-click the registry file (.reg) to merge it into the Registry and confirm the prompts.

     warning:

     The registry file modifies the Windows Registry under the extension-specific key path. This doesn't affect other settings, but as a precaution, you can make a registry backup before applying the file. If you're unsure how to back up the Registry, contact your IT or system administrator.

3. Fully close and restart your browser for the settings to take effect.

Uninstall collector

When you're done testing, remove the browser extension and its system configuration.

1. Remove the browser extension in your browser's extension manager, the same way you would remove any other Chrome or Edge extension.

2. Remove the system configuration:

   • macOS - Remove the configuration profile in System Settings > General > Device Management > Profiles. The exact path may vary depending on your macOS version.

   • Windows - Delete the registry key for the browser you used.

     warning:

     This modifies the Windows Registry. You can make a registry backup before proceeding. If you're unsure how to back up the Registry, contact your IT or system administrator.

     Run the following command in a PowerShell session as Administrator:

     Remove the registry key for Chrome

     Remove-Item -Path "HKLM:\Software\Policies\Google\Chrome\3rdparty\extensions\folndgmoekgkipoolphnkclopeopkecc" -Recurse
     Remove the registry key for Edge

     Remove-Item -Path "HKLM:\SOFTWARE\Policies\Microsoft\Edge\3rdparty\extensions\folndgmoekgkipoolphnkclopeopkecc" -Recurse

Verify deployment status

Verify that the extension is properly configured and connected to AIDR on a user's machine.

Extension status page

In the browser toolbar, click Extensions (the puzzle piece icon in the top-right corner) and select AIDR to open the extension status page showing:

• CrowdStrike AIDR - Extension vendor and name
• Version - Semantic version number (for example, 0.6.4). The first two digits indicate the major and minor feature releases, and the last digit indicates a patch with improvements and/or bug fixes.
• Device - Unique identifier for this extension instance, used to identify the collector instance in AIDR logs and findings. The device ID is re-generated when the extension is re-installed. Collector instances are listed on the collector details page under the Devices tab.
• UserId - Identifier assigned to the userId field in the extension managed storage. If no userId is configured, this field isn't displayed.
• One of the status values in the top right, indicating the current state of the extension.

Not configured

The extension has no configuration in its managed storage.

1. Verify that the configuration profile or registry changes were properly applied to the system.

   JAMF, Intune, and Self-Service apply extension configuration through OS-level settings.

   note:

   If you used Chrome Enterprise to configure the extension, proceed to the next step and check the extension's managed storage.

   You can verify settings made by these or similar tools at the following OS and browser-specific locations:

   • macOS - Managed preference plist files

     Google Chrome

     plutil -p /Library/Managed\ Preferences/<user>/com.google.Chrome.extensions.folndgmoekgkipoolphnkclopeopkecc.plist
     Microsoft Edge

     plutil -p /Library/Managed\ Preferences/<user>/com.microsoft.Edge.extensions.folndgmoekgkipoolphnkclopeopkecc.plist
     Example configuration

     {
       ...
       "registrationIdentity" => "eyJzIj...YiOjF9"
       "urlTemplate" => "https://api.crowdstrike.com/aidr/aiguard"
       "userFullName" => "<user-full-name>"
       "userId" => "<user-id>"
     }

   • Windows - Registry keys

     Google Chrome (PowerShell)

     Get-ItemProperty -Path "HKLM:\Software\Policies\Google\Chrome\3rdparty\extensions\folndgmoekgkipoolphnkclopeopkecc\policy"

     Get-ItemProperty -Path "HKLM:\SOFTWARE\Policies\Microsoft\Edge\3rdparty\extensions\folndgmoekgkipoolphnkclopeopkecc\policy"
     Example configuration

     urlTemplate          : https://api.crowdstrike.com/aidr/aiguard
     registrationIdentity : eyJzIj...I6MX0=
     userId               : <user-id>
     userFullName         : <user-full-name>
     ...

   Next steps:

   • If you don't see the expected values provided on the collector details page in the AIDR console, verify the system configuration process.

2. Verify the extension managed storage has been updated.

   1. In your browser address bar, go to chrome://extensions (or edge://extensions).
   2. Enable Developer mode.
   3. In the AIDR extension card, click service_worker.
   4. In the DevTools console for the background service worker, switch to the Application tab.
   5. Expand Extension storage and click Managed.
   6. Verify the storage keys are populated.

   • Required fields:

     • registrationIdentity - Encoded credentials the extension uses to authenticate with the AIDR service and obtain an authorization token
     • urlTemplate - AIDR API base URL

     You can find collector-specific values for registrationIdentity and urlTemplate under the Install tab on the collector details page in the AIDR console. Configuration files and templates available on the Install tab are pre-populated with these values.

   • Optional user identity fields that appear in AIDR event logs:

     • userId - User identifier (for example, email address). Appears in AIDR logs and findings.
     • userFullName - User's display name. Appears in AIDR logs and findings.
     note:

     Downloaded configuration files are pre-populated with values from the current session:

     • urlTemplate - Set to the AIDR API URL for your CrowdStrike cloud.
     • registrationIdentity - Set to collector-specific credentials.
     • userId and userFullName - Set to the current AIDR console user's information.

     If you distribute the configuration file to other users, update the userId and userFullName fields to match the target user's identity. In production deployments, you typically set these values dynamically per user using variables in endpoint management tools or scripts.

   Next steps:

   • If the extension managed storage isn't populated, ensure that the browser is fully closed and restarted.

Invalid configuration

The configuration exists but is malformed due to invalid format or missing value for registrationIdentity or urlTemplate.

Next steps:

• Re-download and re-apply the configuration.

Error - registration

Device registration failed due to network issues or invalid credentials provided in:

• registrationIdentity
• urlTemplate

Next steps:

• Check network connectivity to the AIDR service.
• Re-download and re-apply the configuration.

Successful registration

Pending approval

The extension instance is registered but awaiting admin activation in the AIDR console.

By default, devices are auto-approved and activated, but if auto-approval isn't enabled or this extension instance has been disabled, it remains in this state until activated.

Next steps:

• On the collector details page, under Devices, find the extension instance by its ID in the list of devices. Open the menu (⋮) in the device row and select Activate.

Error - logging

The extension is registered but can't send monitoring data from a provider site to the AIDR service. This could be due to connectivity issues.

Next steps:

• Check network connectivity to the AIDR service.

Successful deployment

After successful installation and configuration, the status should progress to:

Configured

The extension has valid configuration but hasn't obtained an access token yet. This is a normal transitional state during extension startup. It progresses to Ready automatically within minutes if the configuration values are valid.

note:

Invalid configuration values result in Unsuccessful deployment.

Ready

The extension is configured, authenticated, and ready to monitor supported AI sites. There is no activity detected yet.

Active

The extension is operational and monitoring AI interactions when the user is interacting with a supported provider site.

Verify data flow

A properly deployed collector captures user input and AI service responses on supported provider sites and sends the traffic data to AIDR for analysis. The data is processed according to your collector policy rules, and the results are logged. If the collector's Logging is set to Log with prompt data, the user input and the AI response are included in the logs.

Provider website

Visit a supported provider site (for example, ChatGPT or Claude ) and start interacting with the chat application.

Browser UI

Depending on the collector policy, the AIDR collector may or may not visibly affect the end user experience in the standard browser UI:

• If No Policy, Log Only is assigned, or your selected policy rule actions are all set to Alert and Report, you won't see any visible effects from the AIDR collector.
• If your policy rules have blocking or data-transforming actions, and a rule is matched, you may see blocked or redacted prompts and unexpected responses where sensitive values have been removed before reaching the AI system.

Next steps:

If you don't see AIDR policies applied to the user input:

• Check Input Rules for the policy assigned to your collector.

  tip:

  You can identify your extension instance by:

  • Matching the extension urlTemplate value and the AIDR cloud domain
  • Switching to the correct customer account in the Falcon console (CID)
  • Selecting the correct collector on the Collectors page in the AIDR console
  • Matching the device ID displayed on the extension status page and in the AIDR console for a registered device on the collector details page under Devices

Extension DevTools

Use the extension DevTools to confirm that it's active and sending data to AIDR:

1. In your browser address bar, go to chrome://extensions (or edge://extensions).
2. Enable Developer mode.
3. In the AIDR extension card, click service_worker to open its developer tools.
4. In DevTools, switch to the Network tab.
5. Check for outbound requests to and responses from the AIDR APIs while interacting with a supported AI provider. You may see the following request names:

   • check - Authenticating with the AIDR service and obtaining an authorization token

   • guard_chat_completions - Sending user input or AI system response to AIDR for analysis

     You can inspect the collector payload under the Payload tab and AIDR API responses under the Preview and Response tabs.

     tip:

     See AIDR APIs documentation to better understand the content of the payloads and responses.

Next steps:

If you don't observe network traffic to AIDR APIs from the correctly configured extension, it may be due to:

• Changes on the provider site - Contact AIDR support .
• Your machine policies blocking extension functionality - Contact your IT or system administrator.

AIDR console

In the AIDR console, you can see the detailed event logs saved by your collector, visualize them in a Sankey dashboard, and see metrics associated with the log data.

Data flow timing:

Data appears in AIDR only when users visit and interact with AI provider sites. Installing the extension alone doesn't create data flow.

View detailed logs

Click Findings in the top menu to review events processed by AIDR. You can identify your collector logs by attributes associated with your collector and the provider, for example:

• COLLECTOR TYPE - (for example, Chrome)
• APPLICATION NAME - Provider service name (for example, ChatGPT)
• COLLECTOR NAME - Name you gave to your collector
• TIME - Time of the request

You can see the results of AIDR processing in the following columns:

• STATUS - Policy decision:
  • Allowed - No risks were detected, and the user prompt or AI system response is allowed by AIDR.
  • Reported - Risks were detected, and the detection results are saved in logs, but the user prompt or AI system response is allowed by AIDR.
  • Blocked - Risks were detected, and AIDR responded with a blocked result. Blocking actions set in policy rules are automatically enforced in Browser, MCP, and (depending on configuration) Gateway collectors.
  • Alerted - Blocked result was logged but not enforced in Report Only mode .
  • Transformed - Sensitive data or malicious references were detected and redacted or defanged. The user prompt or AI system response was allowed with the transformed data.
• FINDINGS - Detector(s) that identified the risks. If no detections were made and the request was allowed, No detections is displayed.

You can expand each event log and see additional details, including:

• User prompt or AI response data - If the collector's Logging is set to Log with prompt data, the event logs contain:

  • Guard Input - Original prompt or response submitted to AIDR
  • Guard Output - Processed response, present only if the data was transformed; otherwise, null

• Metadata associated with the request, including:

  • User - Username saved in the extension managed storage
  • AIGuard Config
    • policy - Policy assigned to the collector
  • Findings - Detailed detections report
  • Extra Info
    • app_name - Provider website application name
    • user_name - User's full name saved in the extension managed storage
    • site_url - Provider website location

Use the reload icon to refresh the event log table.

Learn more about the Findings page in the Logs & Findings documentation .

Visualize your data

Click Visibility in the top menu to explore patterns in AI data flows processed by AIDR and metrics associated with this data.

In the interactive Sankey diagram, you can visualize the relationships between different entities captured in the event logs by selecting up to three attributes from the event metadata. For example, you can connect User Name - Application Name - Status to see which user visited which AI provider and what outcomes the AIDR processing produced.

Learn more about visualizing AI flows, supported metadata attributes, and metrics dashboards in the Data Flows & Dashboards documentation .

Devices

The Devices tab displays browser instances that have enrolled with the AIDR browser collector. You can use this page to monitor device activity, manage device enrollment, and revoke tokens for specific devices.

Enable Auto-Enroll

When enabled, browser instances automatically enroll with the collector when users install the extension and configuration profile.

When disabled, new browser instances that register require manual approval for enrollment.

Enable IP Allow List

You can restrict collector access to browsers connecting from specific IP addresses. When enabled, you can add or remove allowed IP addresses.

Device list

Click the menu (⋮) icon in a device row to disable the device, revoke its tokens, or delete its enrollment.

When auto-enrollment is disabled, devices register with Pending status and can't send data to AIDR until you activate them using the Activate option in the device menu.

Policy evaluation and detections

When a browser collector sends captured AI activity to AIDR, AIDR evaluates the data using rules defined in the collector policy. The resulting detections are logged for visibility, investigation, and integration with other security workflows.

Input Rules

You can use browser collectors to enforce input rules that block or redact sensitive data to prevent users from sending potentially harmful content to the AI provider.

Output Rules

You can use browser collectors to detect threats in AI responses, but they can't modify what users see.

Output rules automatically run in Report Only Mode , with only Report and Alert actions available. AIDR logs detections without affecting the user experience.

Format Preserving Encryption (FPE) in browser collectors

Format Preserving Encryption (FPE) encrypts sensitive values while preserving their format (length, character types, delimiter positions). This prevents sensitive data leakage while allowing meaningful prompts to be submitted. For example, a phone number like (555) 123-4567 encrypts to (842) 967-3201 - the format remains recognizable and provides useful context while the original number is protected.

When you apply FPE redaction in input rules:

1. Browser collectors encrypt sensitive data before submitting the data to the AI provider.
2. If the AI provider includes the encrypted data in its response, users see the encrypted version in the same format.

For example, if a user submits SSN 234-56-7890, FPE encrypts it to 987-65-4321. When the AI responds with "Your SSN 987-65-4321 cannot be verified", the user sees the encrypted value and may not recognize it as their original input.

note:

Browser collectors can't unredact FPE-encrypted values that appear in AI provider responses.

tip:

Use other redaction methods (replacement or mask) to make it clear that values were redacted - for example, <US_SSN> or ***-**-7890.

User experience

When prompts are blocked

When the collector blocks a user prompt, the user sees a banner that includes:

• Message indicating that the prompt was blocked
• Request ID that users can copy and provide to Support

For example:

Malicious Prompt was detected and blocked.

Request ID: prq_b6m7di4yao3lc4q75j5lddx5y7licu5v ⧉

When data is transformed

When the collector transforms data submitted to the AI provider, the AI system receives the redacted sensitive values and defanged malicious URLs, IP addresses, and domains. Some sites may show original user input in the chat history.

Users see a banner message that includes:

• Message indicating that sensitive data was redacted or malicious references were defanged
• Request ID that users can copy and provide to Support

For example:

Your organization's security policy modified sensitive or malicious content before sending it to the AI provider.

Request ID: prq_b6m7di4yao3lc4q75j5lddx5y7licu5v ⧉

Users see transformed values in AI responses when the AI includes those values in its output.

Inconsistent behavior across AI provider sites

Different AI provider sites handle AIDR security interventions in unique ways due to variations in their client-side web processing. In addition, a web application implementation could change at any moment. These behaviors are outside AIDR's control and can create inconsistent user experiences across platforms.

Example

The current ChatGPT conversation interface captures user input and then updates chat history based on what was actually processed by the AI model. This creates potentially unexpected behavior depending on how AIDR processes user input:

• When data in a user prompt is transformed by AIDR:

  1. User enters a prompt containing sensitive data.
  2. The user input is added to the chat interface and remains unchanged briefly until ChatGPT updates it based on the model's response.
  3. AIDR browser collector intercepts the prompt, processes it, and sends the transformed version to the AI model.
  4. ChatGPT receives the model response and:
     • Updates the user prompt displayed in the chat interface with the actual prompt received by the model.
     • Adds the model response to the chat history.
  Example exchange:

  • User enters: "Do you know Muffin Man?"
  • User's input is added to the chat history unmodified: "Do you know Muffin Man?".
  • AIDR's Confidential and PII Entity detector replaces the person name with a placeholder before sending the prompt to the AI model.
  • When the model responds:
    • AIDR browser extension shows a banner message.
    • User input in the chat history becomes "Do you know <PERSON>".
    • Model response is added to the chat history and may read: "I do not know who <PERSON> is from that message..."

• When a user prompt is blocked by AIDR, the behavior is different because no content reaches the AI model:

  1. User enters a prompt that will be blocked by AIDR - for example, a harmful intent blocked by the Malicious Prompt detector.
  2. The user input is added to the chat interface.
  3. AIDR browser collector intercepts the prompt, processes it, and blocks it from being sent to the model.
  4. AIDR browser extension shows a banner message.
  5. Because there is no model response, ChatGPT does not update the conversation, making it impossible to remove or modify the user prompt in the chat history.

Other AI providers (Claude, Gemini, enterprise platforms) may handle these scenarios differently due to variations in their client-side implementations.

For example, the current behavior of Claude AI is similar to ChatGPT when a user prompt is transformed, but the prompt is never added to the conversation if blocked by AIDR.

Report Only mode

If browser policy input rules are set to Report, or the policy is in Report Only Mode , the user experience is unaffected. AIDR logs detections without blocking prompts or modifying data.

note:

Output rules in browser policies always run in Report Only Mode.
