AI-Powered API Security Testing and Protection Platform

Akto, founded in 2022 and headquartered in San Francisco, is primarily an API security platform that has recently extended its focus into AI agent and model control.

The company offers broad discovery, testing, posture management, and runtime protection for APIs, including those behind large language models (LLMs), AI agents, and Model Control Points (MCPs).

Akto’s agentic security solution delivers guardrail-style protections (e.g., blocking unauthorized tool calls, prompt injection detection, and data exfiltration monitoring) across AI workflows. It sits at the intersection of API/app security and AI agent governance. The company’s strength lies in visibility into APIs and agent integration points, and less so in fine-grained token-level prompt/output interception.

Akto raised $4.5 million in a seed round led by Accel India in November 2022

ZenGuard provides a verticalized security layer for AI Agent infrastructure.
