NIST announced a paper by Apostol Vassilev in IEEE Security & Privacy arguing, by extension of Gödel's incompleteness results, that no finite set of guardrails can be universally robust against adversarial prompts. NIST recommends a continuous monitor-and-update model: ongoing red teaming, continuous guardrail updates, and operational resilience to limit impact and recover.
Why it matters
It gives US government backing to treating jailbreak and injection defense for agents as an ongoing operational process rather than a certifiable property.
Key facts
As stated in the sources, with where to find them.
- Underlying paper: 'Robust AI Security and Alignment: A Sisyphean Endeavor?', IEEE Security & Privacy, May 2026, DOI 10.1109/MSEC.2026.3678214.NIST news release
- Three recommended elements: continuous red teaming, continuous guardrail updates, and operational resilience; the goal is for exploit discovery cost to exceed attacker resources.NIST news release, recommendations

Key questions this bears on
- Can AI agents defend and oversee systems on their own?Not yet. Agents are weak on realistic defensive benchmarks and monitors can be evaded; assistants help analysts who stay in charge.
