It displays denied HTTPS block-page redirects and reports gateway protection status. [Free in the Chrome Web Store](https://chromewebstore.google.com/detail/block-page-assistant/pkimhjnhalcimiegkknnidjmmoiedhon) adam:ONE® protects devices without the need of an endpoint agent. adam:ONE® assist & Block Page Assistant are browser extensions to help enhance user experience in a ZTc (Zero Trust Connectivity) environment. What it does ## How the extension assists the browser The extension works alongside an adam:ONE®-protected gateway. It does not replace the gateway policy or inspect encrypted traffic on the endpoint. ### Visible block-page redirects Understand when a denied HTTPS site is being redirected to a block page instead of seeing an unexplained failure. ### Inspection workflows Help users respond to denied connections and request inspection or unblock workflows within their deployment. ### Optional reCAPTCHA redirect Support reCAPTCHA when Google domains are denied by redirecting requests to the alternate reCAPTCHA domain. Technical reference ## Platform support and extension behavior Installation, browser compatibility, local service interaction, optional functions, and privacy behavior documented by ADAMnetworks.

Hovering over the extension icon displays the status as text. f4 #### Optional reCAPTCHA redirection Can redirect www\.google.com/recaptcha to www\.recaptcha.net/recaptcha when Google domains are denied. This function is off by default. Enable only when Google is blocked. Sites with a restrictive Content-Security-Policy may reject the redirected CAPTCHA. ### Protection status at a glance The extension icon communicates whether protection is detected for the device. Hovering over the icon also presents the current status as text. ![Block Page Assistant funnel icons indicating protection detected and protection not detected](https://adamnet.works/assets/extension-block-page-status.webp) Block Page Assistant uses its browser icon to indicate whether protection is detected behind the white-label adam:ONE® deployment. ### Feature support grid Feature codes refer to the technical functionality descriptions above. | Browser | f1 (Blocked HTTPS redirection) | f2 (Local extension presence notification) | f3 (Protection-status display) | f4 (Optional reCAPTCHA redirection) | | - | - | - | - | - | | Chrome / Chromium | Supported | Supported | Supported | Supported | ### Optional domain listing When Domain Listing is enabled, the extension popup can show the domains used by the current website and provide a Clear control for starting a fresh list. ![adam ONE assist popup listing the current website domain dependencies](https://adamnet.works/assets/extension-domain-list.webp) When optional Domain Listing is available and enabled, the extension popup shows the current website dependencies and provides a Clear control. ### Setup and use 1. Install Block Page Assistant from the Chrome Web Store in a supported Chromium-based browser. 2. The base functions f1–f3 operate immediately after installation on supported platforms. 3. Use the extension icon to view protection status; hover over it to read the status in text. 4. To activate reCAPTCHA redirection, right-click the extension, open Options, and enable the function only when Google is blocked. ### Privacy and security - When a page fails to load, its domain and path are passed to mytools.management, a local process on the user’s gateway, to determine whether the deployment block page should appear. - This domain and path information does not leave the user’s network. - Users can receive policy-enforcement feedback and trigger an unblock request when protected by ZTc Adaptive Allowlisting. - reCAPTCHA redirection is disabled by default and runs only when the user enables it. ## Implementation note Block Page Assistant is intended for white-label implementations of adam:ONE®. It provides transparent feedback around denied HTTPS sites without requiring the browser to install a third-party certificate for traffic interception. Optional reCAPTCHA redirection remains off until enabled by the user.
