10 Best AI agent security platforms (2026)

Enterprise AI agent security is emerging as a distinct governance category as organizations deploy autonomous tools that can access data, execute commands, and interact with enterprise systems faster than security teams can monitor them. The market is organized around identity governance, runtime protection, enterprise security-platform extensions, and full-lifecycle security, with threats including prompt injection, tool poisoning, credential sprawl, data leakage, and unmonitored “shadow AI” activity from local coding assistants. The overview highlights vendors such as Mintive, Straiker, Palo Alto Networks, Lakera, Linx Security, Zenity, Strac, Microsoft, CrowdStrike, and Endor Labs, while noting industry consolidation through acquisitions involving Protect AI, Portkey, Lakera, Astrix Security, and SGNL. It emphasizes that platform evaluations should examine per-agent identities and credential rotation, the breadth of runtime detection and enforcement, visibility into endpoint-based agents such as Cursor and Claude Code, audit and compliance capabilities, integrations with identity, SIEM, DLP, and business systems, and deployment preferences between managed SaaS and self-hosted infrastructure. Mintive is presented as a governance-focused option centered on MCP and agent gateways, bundled tool permissions, independent agent credentials, monitoring, and policy controls, with claimed enterprise adoption and SOC 2 Type II coverage.
