CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Enterprise security teams deploying AI agents across multiple models and vendors need Aira Security's real-time behavior monitoring to prevent agents from exceeding intended permissions or calling unsafe tools. The platform's policy-based control gates agent interactions at the MCP layer before execution, stopping prompt injection exploits and tool misuse that traditional API security can't catch. Skip this if your AI use is limited to single-model chatbot deployments or if you lack the governance appetite to define and enforce agent behavior policies; Aira assumes you're serious about controlling agent actions, not just logging them after the fact.
