Deploy an AI Agents kill switch in 30 minutes (2026)

Step-by-step: fleet pause, blocked decisions, and operator runbook — using Sanctum Console without rewriting your agent stack.

News cycles (Vertex double agents, mass-exploit headlines) push security leaders to ask for a kill switch this week. Fleet pause in Sanctum Console returns BLOCKED on verify until you resume — without redeploying agents.

Deploy an AI agent kill switch in 30 minutes: what teams should know

Most teams gate their first high-risk action the same day: create an agent in Agents, add a Shield Rule, and approve a held action on Overview. Open the console at console.sanctumruntime.com to start free.

Do we need a sales call before trying it?

No. Sign in, connect an agent with the SDK snippet, and run verifyAction on a staging action. Upgrade when you need fleet controls, compliance exports, or higher volume — not to prove the workflow.

Key takeaways

  • Kill switch must be org-wide, auditable, and tested — not a feature flag buried in code.
  • Pair pause with Runtime Activity so responders see what was blocked.
  • Document resume criteria before you need it in an incident.

Implementation checklist

  1. Runtime Fleet → Pause fleet → confirm banner site-wide.
  2. Verify a test action returns BLOCKED while paused.
  3. Export last hour from Audit Logs for leadership.
  4. Resume after policy tighten in Shield Rules.

What should we buy first — gateway or runtime trust?

Buy operational certainty: Runtime Fleet pause is the fastest org-wide containment lever when agents act as privileged insiders.
