Palo Alto Networks Posts $1.15 Billion Trading Volume (Ranked 65th) as Prisma SASE 4.0 Advances AI-Driven Browser Security and SASE Growth

On September 4, 2025, Palo Alto Networks (PANW) recorded a trading volume of $1.15 billion, ranking 65th in market activity. The stock rose 0.43% amid the launch of Prisma SASE 4.0, an AI-driven cybersecurity solution designed to neutralize sophisticated threats within enterprise browsers. The platform addresses vulnerabilities in traditional secure web gateways by intercepting encrypted, evasive attacks that assemble in real-time within browser environments.

The new release emphasizes browser security as the "operating system" for modern enterprises, highlighting its role in safeguarding AI and cloud applications. Prisma SASE 4.0 introduces AI-augmented data classification, which reduces false positives by 90% compared to conventional methods. With over 140 pre-trained machine learning classifiers, the system secures critical assets such as patents and source code. Private App Security features dynamically adapt to protect dynamic applications from custom-built cyberattacks, replacing outdated static rule-based web application firewalls.

Palo Alto Networks reported $1.3 billion in SASE ARR for fiscal 2025, reflecting a 35% year-over-year growth—outpacing the broader market. The company has held a leadership position in Gartner’s Magic Quadrant for SASE Platforms for three consecutive years. With over 6,300 SASE customers, including one-third of the Fortune 500, the platform’s adoption of Prisma Access Browser now exceeds 6 million licensed seats. The enhancements align with evolving business needs, shifting security focus from threat blocking to enabling growth through streamlined operations.

General availability of Prisma SASE 4.0 features is expected later in 2025. The platform’s browser-based protections and AI-driven data security aim to address the rising complexity of cyberattacks in an increasingly digital enterprise landscape.
