Prisma SASE 4.0 defends against sophisticated, browser-based web threats
Palo Alto Networks recently incorporated AI-driven data security into its secure access service edge (SASE) platform that can now helps customers defend against sophisticated web threats within browsers.
Prisma SASE 4.0 includes new capabilities that provide advanced data security within the browser and constantly update security policies for applications. Prisma Browser covers web threats that legacy offerings miss, according to the company. Critical applications and data reside within the browser, and traditional browsers cannot provide the security controls against the growing number of cyberattacks. Advanced web protection in the Prisma Browser inspects fully rendered web pages and catches threats in real time, according to Palo Alto Networks.
“The traditional perimeter has dissolved, while adversaries armed with AI now launch faster, more sophisticated attacks that can bypass proxies and WAFs [web application firewalls]. They hide in encrypted traffic, assemble malware directly in the browser and exploit DNS at scale,” wrote Palo Alto’s Anupam Upadhyaya, senior vice president of product management for all SASE platforms, in a blog about the product release. “At the same time, sensitive data flows across countless channels (structured and unstructured), documents, source code, and AI-generated content. Traditional security struggles to keep up, while fragmented point tools slow users and create risky workarounds.”
Prisma SASE 4.0 uses augmented classification to automatically classify sensitive information across all formats, including unstructured content and data in use, which results in fewer false positives. The includes more than 140 pre-trained machine learning classifiers and customizable models to secure assets. The new Private App Security feature automatically shields these essential applications and updates security policies for applications, according to Palo Alto.
“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 the widespread adoption of AI tools are making traditional security approaches obsolete,” said Anand Oswal, executive vice president of Network Security at Palo Alto Networks, in a statement. By neutralizing sophisticated threats that evade legacy solutions and directly target the browser, we are setting a new standard for security.”
The Prisma SASE 4.0 product updates are expected to be available later this year.
