Secure Sandboxes for Agents
Perplexity, Tuesday, July 28th, 2026
Perplexity details the sandboxing approach isolating agent execution in its products.
Perplexity published an account of the secure sandboxes underpinning agent execution in its products. Agents that browse, execute code, and interact with authenticated sessions need isolation that limits what a compromised or misdirected run can reach.
The post covers the isolation boundaries implemented and the threat model they address, including prompt injection from web content. It explains the trade-offs between isolation strength and the capability an agent needs to be useful. The piece is an engineering account rather than a product announcement.
