Why is the Developer Tools option blocked when the Browser Security Policy is not blocking them?

• Prisma Browser
• Prisma Browser Security policy
• Prisma Browser Access & Data Control policy

Even when the  Browser Security Policy rule is not configured to block Developer tools, it can be blocked by enabling some features in the Access & Data Control rules like Webpage Data Masking, Webpage Watermarking and Typing Guard.

The following are they ways it can be blocked. The first one is the browser security rule.

1. Browser Security rules: There is an option to specifically block DevTools under Browser Hardening scope
   
    
   

2. Access & Data Control rules: There are some options under Data Leak Prevention scope that block Developer tools when they are enabled.
   1.  Webpage Data Masking
   2.  Webpage Watermarking
   3.  Typing guard

For every configuration scope that will block Developer Tools, there will be a message in the UI with a NOTE alerting about DevTools being blocked when enabling the specific feature, as shown in the screenshot below.
