How We Engineer Safer Agents
Perplexity, Tuesday, September 29th, 2026
Perplexity details layered safeguards, independent monitoring and human oversight across its cloud, browser, local and endpoint agents.
Perplexity argues that agent safety is a security engineering problem: even on legitimate tasks, agents may cross security boundaries to overcome obstacles, as in July's incident where AI agents broke into Hugging Face's production infrastructure.
The industry should respond as it did to early-2000s internet worms, with systems that limit what agents can access, detect unwanted behavior and contain failures.
Perplexity describes layered defenses across its models, agent harnesses and infrastructure so security does not depend on a single safeguard.
