Palo Alto Networks Expands Prisma Browser Beyond Enterprises to Protect SMBs From AI-Driven Threats

Artificial intelligence is moving closer to the edge, with the browser emerging as a key battleground. Startups like Perplexity and The Browser Company are building agentic browsers, while Google and Microsoft are adding AI capabilities to Chrome and Edge, enabling agents to navigate apps, fill forms, and execute workflows like a human. Palo Alto Networks says it anticipated this trend, which inspired its Prisma for Business browser. Initially launched for enterprise, it’s been deployed nearly 10 million times. Now, the firm is extending Prisma to small- and medium-sized businesses, giving these teams stronger protection against threats from malicious actors and AI agents through this critical endpoint.

“We believe that browsers are going to go into a league of their own…we continue to see strength in that category,” chief executive Nikesh Arora remarked during a press briefing last week. He added that, with LLM companies turning browsers and endpoints into platforms where autonomous agents can act on a user’s behalf, they’ve become not just a new frontier to explore but also a potential breeding ground for cybersecurity risks—risks that Palo Alto Networks wants to secure against.

Palo Alto Networks’ Prisma browser is an enterprise browser powered by secure access service edge (SASE), think of it as a cloud-based security and traffic manager that blocks threats and directs users to apps safely and efficiently. Launched in September, it features a workspace that administrators can use to configure and manage the apps and AI tools employees use on any device, at any location. In other words, it lets AI be used to improve productivity while blocking any information from falling into unauthorized hands.

Bringing Prisma to SMBs aims to protect businesses that often lack the resources to detect, intercept, and manage the risks of AI-enabled attacks. According to Palo Alto Networks, small business teams use an average of 36 applications in their browsers, creating exposure to phishing, ransomware, fraud, automated attacks, and threats targeting AI agents and endpoints. In fact, 95 percent of companies report having security incidents come through the browser. Without robust protections, these attacks can disrupt operations, compromise sensitive data, and impose significant financial and operational turmoil on owners.

“Standard browsers weren’t built to stop modern cyberattacks or prevent AI data leaks,” Anupam Upadhyaya, Palo Alto Networks’ senior vice president of product, writes in a release. “We’re providing small businesses with the same protection used by the world’s largest enterprises, but in an easy-to-use, simple to manage workspace with flexible and accessible pricing for any small business.”

Any organization can deploy the Prisma browser—Arora confirms that no prior relationship with Palo Alto Networks is required. All that’s needed is an assigned administrator and a $99 annual subscription per user—there is a 30-day free trial. “It’s designed to be simple so that our customers don’t have to make security decisions,” he explains. “We make the decision for them to make sure they can live in the most secure state.” Highlighting a Google Chrome vulnerability discovered by Palo Alto Networks, in which Gemini could hack the browser and infiltrate an organization’s infrastructure, Arora adds, “This is to make sure that if SMB users start using some of these things, unknowingly causing a security risk, this can be protected by making sure they’re using a secure browser, because that’s where most of the AI apps live.”

And while SMBs gain the same direct protection as their enterprise counterparts, the rollout also tackles a hidden risk: small businesses connected to corporate networks can become unwitting gateways for attackers. Securing these downstream endpoints helps close a potential path to more critical systems. With the rise of more sophisticated agents, exemplified by the OpenClaw, Nemoclaw, Nanobot, and Picoclaw frameworks, protecting a single organization is no longer enough—the security of the entire connected community is at stake.

Palo Alto Networks’ Prisma Browser for Business is available for download today for those in the United States.
