Palo Alto Networks unveils Prisma SASE browser for AI security

Palo Alto Networks has introduced new capabilities in its Prisma SASE platform, including the Prisma Access Browser 2.0, aiming to address contemporary security risks associated with increased browser-based workflows and generative AI usage in modern workplaces.

According to Palo Alto Networks, approximately 85 percent of work currently takes place within browsers, elevating risks related to data exposure and endpoint monitoring. The company's 2025 Unit 42 Incident Report highlights that 44 percent of reported security incidents are connected to activities conducted through employee browsers, including phishing, URL redirect abuse, and malware downloads.

John Grady, Principal Analyst at Enterprise Strategy Group, now part of Omdia, commented on the announcement: "A secure browser extends SASE protection to where knowledge workers spend most of their time, securing third-party access, supporting BYOD, and reducing an organisation's reliance on legacy infrastructure like VDI. Palo Alto Networks unique approach of integrating its Prisma Access Browser with Prisma SASE helps organisations extend the same protection from advanced threats, user experience monitoring, and GenAI app protection from the network into the browser, ensuring users are protected, efficient, and productive."

The Prisma Access Browser 2.0, positioned as the only SASE-native secure browser, is developed to support secure access for a distributed and cloud-focused workforce. It introduces several features aimed at safeguarding the use of generative AI applications, real-time data loss prevention, and advanced threat protection directly within the browser.

The new browser incorporates capabilities such as real-time visibility and access control for generative AI use. By implementing large language model-powered context-based data classification, the system is designed to detect and prevent the unintentional leakage of sensitive data through clipboard functions, printing, screenshots, or typing.

In addition, the browser is equipped with threat detection mechanisms powered by Precision AI, intended to identify sophisticated web-based attacks. These defences address threats such as AI-generated cloaking, SaaS-hosted phishing, evasive code, and malicious injections targeting compromised websites, which often go undetected outside the browser environment.

The platform also aims to provide an improved user experience. Users can reportedly access both modern web and SaaS applications, as well as legacy infrastructure—including virtual desktop infrastructure applications—from a unified, browser-based interface.

Aathir Ahad, CISO at Wipro Limited, shared his perspective: "In the AI-first era, safeguarding customer data and intellectual property is paramount. Prisma Access Browser aligns with our Zero Trust strategy and our commitment to leveraging advanced technologies for rapid threat prevention, enhanced user experience, and robust data & privacy protection."

Expanding on the strategic importance, Anand Oswal, Senior Vice President and General Manager of Network Security at Palo Alto Networks, stated: "Secure browsers are absolutely essential for the modern workforce because today's work is increasingly remote, cloud-based, and data-intensive. This shift demands a unified, modern approach to security — a SASE natively integrated secure browser — that uniquely safeguards productivity, helps ensure resilience, and does so with a seamless user experience, making it the optimal choice for securing today's dynamic work environments."

In addition to Prisma Access Browser 2.0, Palo Alto Networks has introduced other new features to its SASE portfolio. These include Endpoint Data Loss Prevention (DLP) to enhance shadow data discovery and insider risk mitigation, App Acceleration for improved productivity app performance branching through Prisma SD-WAN, and the Next-Generation Unified SASE Agent for streamlining IT operations.

The company has also extended its partnership with Oracle Cloud Infrastructure, aiming to enhance global cloud reach and resilience for Prisma SASE customers.

Karan Batta, Senior Vice President at Oracle Cloud Infrastructure, commented: "Our long-standing collaboration with Palo Alto Networks helps organisations across the world securely accelerate their cloud journey. By leveraging OCI to run Prisma SASE globally, Palo Alto Networks can provide its customers with operational resiliency, high performance, and an exceptional user experience. In addition, Prisma SASE helps our customers protect their OCI environments against emerging and sophisticated cyber threats."

According to the company, the newly announced SASE features are intended to be available in the fourth quarter of its fiscal year 2025.
