Akto

Akto is an AI agent security platform that provides real-time discovery, security testing, red teaming, posture management, and guardrails for AI agents, MCP servers, LLMs, and related tools. Recognized by Gartner as a representative AI agent security platform, Akto helps Fortune 1000 security teams secure AI usage across employee workstations, devices, and homegrown applications. The platform automatically discovers and catalogs MCPs, AI agents, tools, and resources across cloud infrastructure and employee laptops, providing 100x better visibility into agentic actions. Akto conducts automated agentic red teaming to identify vulnerabilities before attackers do, and enforces guardrails at scale to prevent malicious activities. The platform addresses critical AI agent security threats including tool poisoning, line jumping, tool shadowing, prompt injection via tool output, broken authorization, and rug pull attacks across input, execution, and output layers. Akto also offers runtime protection to monitor and block malicious agentic actions in real time, along with resources such as an Agent Identity Security Starter Pack, Top 10 AI Agent Identity Risks guide, and a five-stage AI Agent Identity Security Maturity Model. The platform has analyzed and secured over 1 million AI agent-tool actions with guardrails. Founded in 2022 and headquartered in San Francisco, California, Akto has raised $4.5M in seed funding from Accel.
