Best AI agent security software (2026): buyer’s guide by boundary
Compare execution gates, MCP security, identity, and governance platforms — and what to deploy first if you need controls this quarter.
Search and news in 2026 converge on one lesson: agent security is splitting into gateways, identity, discovery, and execution gates. Buyers who mix categories overpay and still miss tool-side effects. This guide maps what to purchase for each boundary — and where Sanctum fits as the action-layer control plane.
Key takeaways
- Model/API gateways (Portkey-class) route traffic; they do not replace per-action approve/block.
- Post–Vertex “double agent” news pushed BYOSA — pair least privilege with runtime verification.
- 94% of teams in industry surveys say they would switch vendors for stronger agentic controls — execution trust is a buying trigger.
Implementation checklist
- List irreversible actions your agents can take this month.
- Shortlist tools that gate execution, not only log chat.
- Run a one-week pilot: gate send_email or transfer_funds in Sanctum Console.
- Compare audit export and mobile approval before annual contracts.

How fast can we get value from Sanctum Console?
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.
What should we buy first — gateway or runtime trust?
If your agents can send email, move money, or touch production systems, buy execution-time gates first (Sanctum Runtime), then add gateways and identity tools for coverage.
