Prisma Browser is a web security solution from Palo Alto Networks designed to protect users where most work actually happens—inside the browser. It focuses on securing web activity, which is especially important now that about 85% of work is done on the web.

It’s built for organizations that want stronger protection against modern, browser-based threats without stitching together multiple tools. Prisma Browser is trusted by over 30 of the Fortune 500, making it a good fit for enterprises that need scalable, enterprise-grade browser security that integrates cleanly into existing environments.

Prisma Browser is powered by Precision AI to help organizations rethink how they secure browser activity. It’s designed to stop:

• Zero-day exploits that take advantage of previously unknown vulnerabilities
• Reassembly attacks that try to evade traditional detection by breaking payloads into smaller pieces
• AI-driven phishing campaigns that are more targeted and convincing
• Malicious browser extensions that can steal data or weaken security

By applying AI to real-time browser activity, Prisma Browser helps identify and block these threats before they impact users or data, giving security teams more confidence in their web environment.

Prisma Browser is designed to reimagine browser security by consolidating protection into a single, integrated solution rather than relying on multiple add-ons or point products.

It brings together three core security modules:

• Advanced Web Protection – safeguards users from web-based threats as they browse and work online.
• Advanced eXtension Security – monitors and controls browser extensions to prevent malicious or risky add-ons.
• Advanced Browser Protection – hardens the browser itself against exploits and attacks.

Because these capabilities are integrated, Prisma Browser delivers strong protection without extra integrations or bolt-ons, helping security teams simplify their stack while improving coverage where users spend most of their time.
