Straiker

Straiker is an AI-native security company for agentic AI, founded by security veterans from Palo Alto Networks. It protects every layer of AI agent deployments from prompts to infrastructure with a closed-loop system that pairs autonomous adversarial testing with sub-second runtime defense. Its products are Ascend AI (autonomous AI threat detection that integrates into CI/CD to test agents for prompt injection, tool manipulation, goal hijacking and data leakage), Defend AI (agentic runtime security that blocks identity abuse, memory poisoning, data exfiltration and malicious MCP connections in real time using proprietary LLM judges), and Discover AI (agent/MCP discovery and posture management). Straiker is backed by Bain Capital Ventures and Lightspeed Venture Partners. Its developer documentation and API/SDK integration surface are gated behind an enterprise access code; there is no public API reference.

Straiker is profiled on the APIs.io network. Tagged areas include Company, Security, Artificial Intelligence, AI Security, and Agentic AI.

Straiker’s developer surface includes documentation, engineering blog, support, and 6 more developer resources.
