ThreatLocker Web Control Autor: ThreatLocker, Inc.

Overview
The ThreatLocker Web Control Extension strengthens security by verifying blocked websites and enabling access requests when allowed by administrators.

If a site is blocked by a ThreatLocker Web Control policy, the extension informs users why and, if permitted, offers a request option. If ThreatLocker or Web Control isn’t installed or configured, the extension stays inactive and won’t interfere with browsing.

How It Works
The ThreatLocker Web Control:

• Detects blocked websites: When a site is blocked due to a network access restriction, the extension checks if the restriction was enforced by ThreatLocker.
• Enforces your ThreatLocker security policies: The extension securely communicates with the locally installed ThreatLocker security service (http://localhost:5252/) to determine if the block was policy-enforced.
• Provides Access Request option: If permitted by the blocking policy, users will be automatically redirected to a web page where they can request access.
• Ensures seamless browsing: If a site is blocked for reasons unrelated to ThreatLocker (e.g., general network issues), the extension takes no action.

Key features

• Seamless Integration: Works in the background with the ThreatLocker security suite.
• No tracking: The extension does not collect, store, or share browsing data.
• Secure & private: Only interacts with a trusted, locally installed ThreatLocker service.
• Lightweight & non-intrusive: If ThreatLocker is not installed, the extension remains idle.
• Fast & reliable: Quickly verifies blocked sites and provides an option to request access.

Permissions & Why They Are Needed
The extension requires a minimal set of permissions to function properly:

• webNavigation: Detects when a site is blocked due to network restrictions.
• tabs: Retrieves the URL of blocked pages for verification.
• host permission (http://localhost:5252/): Communicates with the ThreatLocker service for policy verification.

Privacy and Security First
The ThreatLocker Web Control extension prioritizes your privacy and security. It does not track browsing activity, inject scripts, or modify web content.

• No tracking or data collection: URLs are processed locally, never stored or sent externally.
• No third-party services: All communication stays secure between the extension and your local ThreatLocker service.
• Minimal access, maximum security: Only the necessary data is used to enforce security policies.

Who Should Use This Extension?
This extension is designed exclusively for ThreatLocker users with the Web Control module enabled. If your organization uses ThreatLocker, this extension helps ensure a smooth, secure browsing experience while allowing access requests when necessary.

If ThreatLocker is not installed or active, the extension remains idle and does not interfere with browsing.
