HOL Guard

HOL Guard is an AI security platform that acts as a firewall and antivirus for AI agents, assistants, and autonomous workflows. It helps individuals and organizations safely adopt AI by controlling what AI systems can access and do before risky actions execute.

HOL Guard protects against prompt injection, secret and credential exfiltration, malicious or changed MCP servers, unsafe plugins and skills, supply-chain attacks, destructive commands, unauthorized network access, and unexpected changes to AI tools or configurations. Its local-first runtime enforcement can block, approve, or review AI actions while keeping sensitive code, prompts, files, and credentials private.

For teams and enterprises, HOL Guard adds centralized AI governance with shared security policies, approval workflows, alerts, evidence and audit trails, investigations, device and agent visibility, integrations, and enterprise deployment options.

HOL Guard is vendor-neutral and designed to work across the growing AI ecosystem rather than locking customers into a single model or platform. It supports leading agentic environments and provides a consistent security layer as organizations expand their use of AI across engineering and other business workflows.
