[Prisma SASE 4.0](https://www.paloaltonetworks.com/blog/tag/prisma-sase-4-0/?ts=markdown)  
[Secure Browser](https://www.paloaltonetworks.com/blog/tag/secure-browser/?ts=markdown)

Employees often create, collaborate and connect through web, SaaS, GenAI and private applications from unmanaged devices and unmonitored networks, all within the browser. With more than [85% of daily work happening there](https://start.paloaltonetworks.com/Omdia-state-of-workforce-security), the browser has become the primary attack surface of the modern enterprise.

Attackers know this and use the browser to deliver or launch attacks---from phishing and credential theft to data exfiltration. Encrypted traffic, trusted SaaS platforms and increasingly sophisticated evasion techniques have pushed these threats beyond the visibility of traditional network and endpoint tools. Today, [95% of organizations report attacks originating in the browser](https://start.paloaltonetworks.com/Omdia-state-of-workforce-security), which now serves as the execution point or initial entry for[70% of malware](https://www.infosecurity-magazine.com/news/browser-cyberthreats-surge-email/).

The only way to close this gap is to secure the browser itself, which is why enterprises are adopting Prisma Browser to gain visibility, control and security where work happens.

# Why Traditional Defenses Fail

Even the most advanced network and endpoint defenses lose sight of what happens inside the browser. These solutions can't see the webpages that load dynamically, the background code that runs silently, or the actions users take within SaaS and GenAI apps. It's in those unseen moments that modern attacks now take shape and where true visibility begins.

# A New Model for a New Reality

Securing the browser isn't just an evolution but a necessary shift in how we defend the modern enterprise. [Prisma Browser](https://www.paloaltonetworks.com/sase/prisma-browser) introduces a new model for web security, extending your existing defenses directly into the browser where today's work and threats converge. Built to complement your [SASE](https://www.paloaltonetworks.com/sase)architecture or work standalone, Prisma Browser delivers real-time security and a seamless user experience for every user,[on any device](https://www.paloaltonetworks.com/sase/secure-work-on-any-device), in any app, to keep pace with how work now happens.

# Fight AI with AI: How Prisma Browser Changes the Game

Because the browser is where web content executes, Prisma Browser has an unparalleled vantage point. It sees every request, response, dynamic page change, script execution and user interaction, giving it full visibility into all web activity without decryption or added latency.

This visibility unleashes the full power of Precision AI across all traffic, including encrypted traffic, to detect, analyze and stop even the most evasive, AI-driven threats as they happen. From this foundation, Prisma Browser delivers complete web protection with multiple interconnected capabilities that reinforce each other to secure users, data and applications at the point of use.

## See Everything: Total Visibility and Threat Intelligence

Advanced Web Protection continuously scans every webpage and component in real time to expose hidden code, malicious scripts and web-based threats. Ongoing scanning keeps users safe even as content updates.

## Stop the Unknown: Malware and Exploit Prevention

With [Advanced WildFire®](https://www.paloaltonetworks.com/network-security/advanced-wildfire), Prisma Browser extends malware detection to all traffic---including the[64% of web traffic that remains encrypted](https://start.paloaltonetworks.com/Omdia-state-of-workforce-security)---scanning even large files before they're uploaded or downloaded. It identifies up to 8.95 million new and unique attacks every day to help ensure threats are detected and neutralized before they reach the endpoint.

In 2024 alone, 328 vulnerabilities were discovered across major browsers, and [75 zero-days](https://cloud.google.com/blog/topics/threat-intelligence/2024-zero-day-trends?)were exploited in the wild, serving as a sharp reminder that browsers are now prime targets for attackers. These exploits allow adversaries to hijack sessions, steal credentials, or take over endpoints before patches are even available.

Advanced Browser Protection uses patented exploit-mitigation technology to block zero-days before they're weaponized, enforce patching, and neutralize risky browser components such as WebRTC or WebGL. It can also redirect traffic to [Remote Browser Isolation](https://www.paloaltonetworks.com/sase/remote-browser-isolation) when necessary.

## Control the Unseen: Extension Governance

Browser extensions have become one of the most underestimated security risks. A Stanford University study revealed that more than[280 million users](https://techxplore.com/news/2024-06-experts-millions-users-malware-infected.html?utm_source=chatgpt.com#google_vignette) unknowingly downloaded malicious extensions that are often disguised as productivity tools, password managers or AI helpers.

Advanced Extension Security gives organizations complete insight and control over every browser extension. It continuously monitors permissions, updates and usage, blocking malicious or risky extensions automatically. With this visibility, security teams finally regain control of what was once a blind spot in the browser ecosystem.

## Empower Every User: Awareness as Defense

Prisma Browser turns every user into a defender by transforming the browser into a live point of engagement between users and security. It delivers real-time prompts that turn into an active, always-on layer of defense. These prompts include user alerts for when someone is the first to access a new site, when they've marked sensitive fields or received risky emails, as well as help prevent credential reuse.

# Embrace Complete Web Protection with Prisma Browser

Attackers have already moved their operations into the browser, but legacy defenses can't follow them there. Prisma Browser can follow malicious actors with a new class of browser-native innovations that redefine how web protection is delivered and provides complete visibility powered by Precision AI.

Prisma Browser stops what traditional tools cannot see---dynamic web attacks, credential theft, malicious extensions and zero-day exploits---neutralizing threats at the point of use before they become breaches. The result is a unified, intelligent defense layer that protects users, data and applications, transforming the browser from a target into one of your strongest lines of defense.

Security no longer ends at the browser; it begins there. Browse Bravely.
