The Prisma Access Browser Extension

The Prisma Access Browser Extension is a tool that allows organizations to apply some of the Prisma Access Secure Enterprise Browser functionality without installing the full browser.
Where Can I Use This?What Do I Need?
  • Strata Cloud Manager
  • Prisma Access Browser standalone
  • Prisma Access with Prisma Access Browser bundle license or Prisma Access Browser standalone license
  • Superuser or Prisma Access Browser role
The Prisma Access Browser Extension is a tool that you can install on commercial browsers such as Google Chrome and Microsoft Edge browsers, running on Windows, macOS, and ChromeOS Operating Systems
IT and security teams can enhance organizational security by implementing Prisma Access Browser with a hybrid strategy, using the Prisma Access Browser Extension to bridge current browsing practices with advanced protections. This approach enables employees to continue using familiar browsers while administrators gain greater visibility and control over all browsers across the enterprise.
The extension actively monitors user activity on commercial browsers, helping to mitigate Shadow IT risks and providing real-time phishing protection. By centralizing visibility and allowing consistent enforcement of security policies, the Prisma Access Browser Extension integrates smoothly with existing tools while guiding users to the enterprise browser when accessing sensitive applications.
Designed as a foundational layer in a phased deployment, the Prisma Access Browser Extension supports a secure transition toward full adoption of the Prisma Access Browser. For scenarios requiring heightened protection, such as critical applications or high-risk users, a full enterprise browser deployment offers unparalleled control and functionality, setting a gold standard for security. This hybrid solution thus delivers immediate security benefits while preparing organizations for comprehensive, enterprise-grade browser security.

Deploy the Prisma Access Browser Extension

The Prisma Access Browser Extension can be installed on chromium-based browsers (Chrome, Edge, Arc, Brave), running on Windows, macOS, and ChromeOS Operating System.
The extension deployment is based on the operating system, the IdP, and the browser type. Currently, Okta, Azure, and Google are the supported IdP applications.
More information on deploying the Prisma Access Browser Extension can be found in the Prisma Access Browser Setup page: (Strata Cloud Manager -> Workflows -> Prisma Access Setup -> Prisma Access Browser -> Step 5: Download and Distribute.

Prisma Access Browser Extension Login Enforcement

Currently, the Prisma Access Browser Extension utilizes an automatic login feature that detects the user names from the most recent login to a web Identity Provider (IdP) application before applying Prisma Access Browser Extension policies. In some cases, the user name may not be recognized, preventing the Browser Extension from logging in and enforcing the admin policy. This occurs mainly in cases where the user has not yet logged into any IdP applications on their browser.
To avoid situations like this, the Prisma Access Browser Extension includes a feature that you can configure that requires logging into the Prisma Access Browser Extension before accessing specified sites. This prevents users from bypassing the administrative policies by using applications without the proper login.
To configure the Login Enforcement Policy, follow the procedures for creating a new Data Control rule. Take note of the following requirements:
  1. In the Scope section, select the user Anonymous PABX.
    When you select the Anonymous PABX user, several sections in the Add rule wizard will be unavailable. Some of the options in the available sections will also be unavailable.
  2. In the Destinations section, configure the applications and URLs that users will be allowed to access without being logged in to the IdP.
  3. In the Web Access section, select Allow.
    Now you will create the second part of the Login Enforcement:
  4. In the Scope section, select the user Anonymous PABX.
  5. In the Destinations section, configure the applications and URLs that users will be not be allowed to access without being logged in to the IdP.
  6. In the Web Access section, select Block
Please do not block the IdP URLs in the Web application step. This will prevent users from logging into the Prisma Access Browser Extension.
