Palo Alto Networks®, the global cybersecurity leader, has unveiled Prisma® SASE 4.0, introducing new capabilities that extend protection directly into the browser—now the core gateway to enterprise applications and data. The update includes Prisma Browser, designed to neutralize sophisticated, evasive web threats that traditional secure web gateways fail to detect.
As businesses increasingly rely on browsers for AI-driven and cloud-based applications, consumer-grade solutions lack the enterprise-level safeguards needed to defend against encrypted and evasive attacks. Prisma Browser provides real-time in-browser protection, identifying and stopping malware before it can infiltrate systems—establishing a new layer of defense critical for modern enterprises.
Prisma SASE 4.0 also enhances data and application security with innovations tailored for today’s digital workforce:
-
AI-Driven Data Security: Using AI-augmented classification, Prisma SASE 4.0 achieves 10x fewer false positives compared to traditional methods. With over 140 pre-trained machine learning classifiers and customizable models, it can automatically protect sensitive assets such as patents, contracts, and source code.
-
Private App Security: To counter advanced attacks on dynamic applications, Prisma SASE 4.0 introduces adaptive protection that continuously updates policies, outperforming outdated static WAF systems.

“The conversation with business leaders has evolved. It’s no longer just about blocking threats—it’s about enabling growth,” said Anand Oswal, Executive Vice President of Network Security at Palo Alto Networks. “The innovations in Prisma SASE 4.0, particularly our last-mile protections in the browser, are a direct response to the digital landscape, where AI-driven attacks and widespread adoption of AI tools are making traditional security approaches obsolete.”
Palo Alto Networks’ leadership in SASE continues to accelerate, with annual recurring revenue reaching $1.3 billion in FY2025, up 35% year-over-year—more than twice the overall market’s growth rate. With over 6,300 SASE customers, including one-third of the Fortune 500, the company is advancing its single-vendor platform strategy, simplifying security operations while scaling to meet global demand.
