Palo Alto Networks unveils Prisma SASE 4.0 with AI-augmented security features.

Palo Alto Networks has announced Prisma SASE 4.0, an AI-driven secure access service edge solution that protects against highly evasive threats assembled within the browser. It offers AI-augmented data classification and secures dynamic private applications. The solution aims to scale SASE beyond $1.3B in annual recurring revenue and provides best-in-class security to one-third of the Fortune 500.

Palo Alto Networks has announced Prisma SASE 4.0, an advanced AI-driven secure access service edge (SASE) solution designed to protect against highly evasive threats that assemble within the browser. The new solution, which will be generally available later this year, offers AI-augmented data classification and secures dynamic private applications [1].

Prisma SASE 4.0 introduces innovative features in Prisma Access Browser that neutralize sophisticated web threats in real-time directly within the browser. This addresses a critical blind spot for legacy solutions and sets a new standard in browser security [1]. The browser is increasingly becoming the primary interface for AI and cloud applications, making it a prime target for cyberattacks. Traditional consumer-grade browsers lack the necessary security controls to protect against these threats [1].

The solution provides several key capabilities to secure the modern workforce:

1. Unprecedented Data Security: Prisma SASE 4.0 offers a unified, frictionless data security approach powered by AI. It uses AI-augmented classification to automatically and precisely classify sensitive information across all formats, including unstructured content and data in use. This results in 10x fewer false positives than traditional methods and includes over 140 pre-trained machine learning classifiers and customizable models to secure critical assets like patents, contracts, and source code [1].

2. Smarter, Faster Protection with Private App Security: Private applications are the engine of many businesses and are prime targets for cyberattacks. Older static rule-based web application firewalls (WAF) are no match for threats custom-built for dynamic applications. Palo Alto Networks' new Private App Security automatically adapts to shield these essential applications and constantly updates security policies for applications [1].

Palo Alto Networks' leadership in SASE is evident by its market leadership and disruptive innovation. The company's SASE ARR reached $1.3 billion in fiscal year 2025, growing 35% year-over-year, more than twice the rate of the overall market [1]. For three consecutive years, Palo Alto Networks has been named a Leader in the Gartner® Magic Quadrant™ for SASE Platforms for Prisma SASE. Additionally, the company has been named a Leader for three consecutive years in the Magic Quadrant for Security Service Edge and five times in the Magic Quadrant for SD-WAN [1]. With over 6,300 SASE customers, including one-third of the Fortune 500, this single-vendor platform simplifies operations and provides a clear path to scale [1].
