What happened
Perplexity introduced SPACE (July 15, 2026), a Firecracker-microVM-based sandbox platform with per-session credential isolation (credentials never enter the sandbox), egress network controls, and rolling snapshots for pause/resume/fork of long-running agent sessions; it already handles 100% of Perplexity Computer's production traffic.
Why it matters
Addresses a core agentic-AI security gap — compromised agents having standing access to credentials/data — via architecture-level isolation rather than policy alone, and is already running at production scale, not just a design doc.
Applicability
Teams building or operating long-running autonomous agents (code execution, browser automation) should evaluate SPACE's architecture patterns (external credential injection, network gateway, snapshot isolation) even if not adopting Perplexity's product directly.
