# Best AI Agent Security & Governance Tools 2026

## TL;DR

AI agent security in 2026 is no longer a prompt-filter checkbox. Production agents need runtime policy, identity, tool permissions, traces, evals, red-team regression tests, compliance exports, and data-boundary controls. The strongest stack combines a neutral threat model such as OWASP Top 10 for Agentic Applications 2026, runtime governance such as Microsoft Agent Governance Toolkit, workflow safety tests such as RAMPART and Clarity, vendor compliance APIs such as Anthropic Compliance API, and developer guardrails such as OpenAI Agents SDK. Buy one tool only after you know which layer it controls: input, tool call, memory, identity, runtime, audit, or incident response.
