Straiker

Straiker is an agentic AI security company headquartered in Mountain View, California. Founded in 2024, Straiker gives security teams visibility and control across the AI agent lifecycle. Its Attack to Defend approach connects discovery, adversarial testing, runtime protection, and containment, helping teams find their agents, expose weaknesses, stop attacks, and take control when needed. Straiker raised a $64 million Series A in June 2026, bringing total funding to $85 million, and works with Fortune 500 enterprises and frontier AI labs to secure internally built and third-party AI agents. Straiker secures AI agents across the enterprise, including coding agents such as Claude Code, GitHub Copilot, Cursor, and OpenAI Codex; productivity agents such as ChatGPT Enterprise, Microsoft Copilot, Claude, and Gemini; and custom agents built with AWS Bedrock AgentCore, Microsoft AI Foundry, Salesforce Agentforce, Databricks Mosaic AI, and Snowflake Cortex. Straiker also secures MCP servers, Skills, tools, and other agentic applications. Straiker provides security across this agentic attack surface through: - AI agent discovery and inventory: Find agents, MCP servers, Skills, tools, models, and integrations. - AI security posture management: Identify risky permissions, connections, misconfigurations, and vulnerable MCP servers. - AI agent red teaming: Test for prompt injection, data exfiltration, tool misuse, agent manipulation, and other attack paths. - Runtime AI security: Monitor and block malicious or unauthorized agent behavior in real time. - Agent containment: Isolate, suspend, restrict, or shut down compromised or misbehaving agents.
