    How Perplexity built security into its Computer agent

    Perplexity just broke down the security architecture behind Perplexity Computer, its autonomous agent that executes code and browses the web. Each task runs inside an isolated Firecracker microVM with its own Linux kernel, backed by a four-layer prompt injection defense audited by Trail of Bits. It addresses the biggest hurdle to enterprise agent adoption: preventing rogue actions and untrusted data leaks.

    Perplexity launches AI security institute led by Purdue professor

    Perplexity just launched the Secure Intelligence Institute (SII), its new research hub dedicated to AI safety, privacy, and trust. Led by Purdue computer science professor Dr. Ninghui Li, the initiative builds on existing work like BrowseSafe to tackle authentication and defenses for autonomous agents. Why it matters: As AI systems shift from answering questions to taking real-world actions, locking down agentic security is becoming a critical battleground.
