Palo Alto Networks is expanding its product portfolio with a new platform for protecting AI models and an upgraded version of its security-optimized browser. The company debuted the offerings against the backdrop of the news that it’s acquiring cybersecurity startup Protect. After the acquisition, the Protect AI team will join the company to help enhance Prisma AIRS, a new AI security platform it debuted in conjunction with the deal. The offering covers many of the same use cases as Protect AI’s product suite. Before deploying a new AI workload to production, a company can use Prisma AIRS to test it for vulnerabilities. The platform includes a tool that automatically performs red-teaming, the task of simulating cyberattacks to find weak points in an application. Prisma AIRS spots misconfigured access permissions, AI models that are susceptible to tempering and other risks. Once an AI workload is deployed in production, Prisma AIRS filters malicious prompts using a runtime security component. It also spots other issues. The software blocks, among others, hallucinations and requests that may cause an AI application to use an excessive amount of hardware resources. A third set of features in Prisma AIRS is designed to protect AI agents. The platform can spot tool misuse, or cyberattacks that target the applications an AI agent uses to perform tasks. The first set of upgrades is rolling out to Prisma Access Browser, a browser that uses AI to block malicious websites. The latest Prisma Access Browser release includes new detections, automated workflows for spotting cyberattacks. According to Palo Alto Networks, they can detect browser-in-the-browser phishing attacks.
