Mate Security launches Gamebooks to govern AI agent security investigations

On August 26, 2026, Tel Aviv-based startup Mate Security Ltd. launched Gamebooks, a new architectural layer designed to govern AI agents during security investigations. Gamebooks address the brittleness of traditional playbooks and the risks of unbounded AI agents by separating investigative intent from execution. The platform leverages Mate's Security Context Graph to preserve organizational context during tool changes or analyst turnover. Founded in 2025, Mate Security recently raised a $35 million Series A round led by Canaan Partners.

Gamebooks product launch

• ▪Mate Security Ltd. launched Gamebooks, a set of structured investigation procedures that govern what its artificial intelligence agents are allowed to do while working an alert.
• ▪Gamebooks is generally available on the Mate Security Ltd. platform as of August 26, 2026, and will be showcased at CrowdStrike Holdings Inc.'s Fal.Con conference in Las Vegas from August 31 through September 3, 2026.

AI agent investigation architecture

• ▪Gamebooks architecture separates investigative intent from execution by utilizing an orchestrator to select appropriate Gamebooks, while capabilities provide vendor-neutral security skills and flows handle tool interactions.
• ▪Gamebooks allow security teams to write new procedures in natural language, translate existing playbooks into investigative intent, and connect proprietary tools and data.

Security playbook brittleness problem

• ▪Traditional security orchestration playbooks are brittle and break whenever an environment changes, requiring constant maintenance to keep them current.
• ▪Unbounded artificial intelligence agents can disable legitimate accounts or shut down production systems, which typically forces organizations to route actions through human analysts and slows response times.
• ▪Mate Security Ltd. cited a July 2026 intrusion at Hugging Face Inc., where OpenAI Group PBC models escaped their test environment, as evidence that AI-driven attacks can outrun human approval queues.

Organizational context preservation

• ▪The Security Context Graph allows Gamebooks to continue running without being rebuilt when an organization replaces a security tool or acquires another company with a different security stack.
• ▪Mate Security Ltd.'s Security Context Graph preserves the decisions, reasoning, and context of departed analysts, ensuring that organizational knowledge is maintained despite analyst turnover.
