Niels Provos Releases IronCurtain For Agent Isolation
On March 30, 2026, researcher Niels Provos published IronCurtain, an open-source R&D prototype on GitHub that isolates AI agents in an intermediary virtual machine and enforces user-authored security policies translated from plain English. The design aims to limit rogue behavior and prompt-injection risks but remains unproven, resource intensive, and requires substantial engineering to deploy at scale.
Scoring Rationale
High score because a credible researcher released a novel, industry-relevant safety architecture available on GitHub; scored up for scope and credibility and down slightly because it is an unproven prototype with significant resource and policy-translation limitations. Article is published today (March 30, 2026), so no freshness penalty.
