PaloAlto Networks Redefines SASE Prisma Browser, Neutralizing Highly Evasive Threats
14th September 2025, Kathmandu
Palo Alto Networks, the global leader in cybersecurity, has unveiled a new era of secure access with the launch of Prisma SASE 4.0.
PaloAlto Networks SASE Prisma Browser
This latest evolution of their Secure Access Service Edge (SASE) solution introduces groundbreaking capabilities, most notably the Prisma Browser, to combat a new generation of highly evasive, AI-driven cyber threats.
The modern enterprise has shifted its core operations to the browser, making it the new front line for cyber defense. Traditional security solutions, including legacy secure web gateways, often fail to protect against sophisticated attacks that assemble and execute directly within the browser, where critical blind spots exist. Prisma SASE 4.0 is engineered to close this gap.
Its new in-browser advanced web protection identifies and neutralizes malware in real time, stopping threats before they can inflict damage.
Key Innovations of Prisma SASE 4.0
Prisma Browser for Last-Mile Defense: The browser is no longer just a window to the internet; it’s the primary workspace for AI and cloud applications. Prisma Browser is a purpose-built, SASE-native solution that provides a critical layer of defense, neutralizing encrypted, evasive attacks that traditional tools miss. With over 6 million licensed seats already adopted, it’s quickly becoming a standard for enterprise security.
AI-Augmented Data Security
As AI agents and copilots become ubiquitous, protecting sensitive corporate data is paramount. Prisma SASE 4.0 delivers a unified, frictionless data security approach powered by AI. Its augmented classification precisely identifies sensitive information across all formats, including unstructured content and data in use, achieving up to 10x fewer false positives than conventional methods. This includes over 140 pre-trained machine learning classifiers and customizable models to safeguard valuable assets like patents and contracts.
Dynamic Private Application Security
The new Private App Security feature moves beyond static, rule-based web application firewalls (WAFs) to provide smarter, faster protection for dynamic private applications. This intelligent defense automatically adapts to shield essential business applications from modern threats, ensuring policies are constantly updated to match evolving risks.
Leading the SASE Market with Unprecedented Growth
Palo Alto Networks continues to cement its market leadership in the SASE space. The company’s SASE Annual Recurring Revenue (ARR) has surpassed $1.3 billion in fiscal year 2025, demonstrating a remarkable 35% year-over-year growth—more than double the market’s rate. This growth is fueled by strong customer adoption, including one-third of the Fortune 500, who rely on the single-vendor Prisma SASE platform for its best-in-class security and operational simplicity.
The company’s position as a Leader in the Gartner® Magic Quadrant™ for SASE Platforms for three consecutive years further validates its leadership and commitment to disruptive innovation.
According to Anand Oswal, Executive Vice President of Network Security at Palo Alto Networks, “The conversation with business leaders has evolved. It’s no longer just about blocking threats—it’s about enabling growth. By neutralizing sophisticated threats that evade legacy solutions and directly targeting the browser, we are setting a new standard for security.”
With these new capabilities, Palo Alto Networks is not just keeping pace with the threat landscape; it is anticipating and shaping the future of enterprise security, ensuring businesses can embrace AI and cloud transformation with confidence.
