Proofpoint ZenWeb Browser Extension for the Agent

Proofpoint ZenWeb is an optional module that does not require an additional license. It is built as a Chromium-based extension utilizing the Chrome API.

Proofpoint ZenWeb browser extension enhances existing endpoint data leak prevention capabilities. It is an add-on to Proofpoint’s agent and improves user experience and enhances web upload blocking accuracy. The extension acts as an add-on to the agent and use it for rule assessment, content scanning and sending data to the customer tenant in Proofpoint’s tenant.

Agent Behavior With ZenWeb

Proofpoint ZenWeb provides an accurate and independent method using Web Accessibility. When the Proofpoint ZenWeb is installed and enabled, URL is extracted accurately and independently during Web activity using Web Accessibility.

Without Proofpoint ZenWeb, Proofpoint Agent initially tries to extract the URL during Web activity from Web Accessibility. If Web Accessibility cannot be used, URL is extracted directly from the Browser Address Bar. Extraction from the Browser Address Bar is less accurate and may contain a partial URL if it currently being typed - and not the actual URL that was opened. This can cause latency to the browser experience.

Installation

After the initial download, the Proofpoint ZenWeb is automatically updated to the latest version.

You can install the Proofpoint ZenWeb on a single endpoint or deploy on multiple endpoints (GPO).

For instructions to install Proofpoint ZenWeb on a single endpoint and on multiple endpoints, see Proofpoint ZenWeb Deployment and Installation.

Incognito Mode

Proofpoint ZenWeb cannot work in Incognito mode without explicit permission by the user. To ensure that Incognito browsing does not become an unmonitored exit point for Proofpoint's ITM/DLP agent, do the following:

Enabling Proofpoint ZenWeb and Activities

You must enable the Proofpoint ZenWeb Browser Extension from the Agent Realm. To enable, from the Administration application, select Endpoints > Agent Realms. In the Advanced Settings of the Agent Realm, in the Browser Extension area, turn on Enable Browser Extension.

Next, enable the specific activities you want to use with the Browser Extension. If an activity is not enabled, the Agent will run without using the browser.
