Straiker

Straiker is an agentic AI security company that provides software for monitoring, testing, and protecting autonomous AI agents across enterprise environments. The platform offers three core products: Discover AI, which maps every AI agent, MCP server, and agentic workflow for visibility and governance; Ascend AI, which performs continuous adversarial red-teaming to expose attack paths including prompt injection, goal hijacking, and tool misuse before production; and Defend AI, which provides runtime security and guardrails to detect and block identity abuse, memory poisoning, data exfiltration, and resource exploitation in real time. Straiker's STAR Labs research has found that 28.6% of cataloged MCP tools are dangerous, 91% of attacks on productivity agents result in silent data exfiltration, and 36% of successful attacks on coding agents lead to remote code execution. The company serves banks, healthcare, technology companies, retail, and media. Founded and headquartered in Sunnyvale, California, Straiker has raised $85.0M in Series A funding from investors including Lightspeed Venture Partners, Bain Capital Ventures, Marathon, Citi, Illuminate Financial, and Workday Ventures.
