About Sealgate
SealGate provides a security layer for AI agents. It sells a gateway that sits between agents and company data, giving security teams visibility and control over agent actions at runtime. The product is aimed at developers building agents for enterprises, managed security providers, and CISOs who need to govern agent behaviour. The gateway connects agents to tools and data through one enforcement point. Policies are set in plain language and enforced deterministically, so the same action always gets the same decision. It blocks actions that carry personal data, secrets, or prompt injection before they run. Every tool call is logged and streamed to a SIEM. SealGate also discovers unauthorised MCP servers on managed devices and quarantines them until approved. It can be deployed as a cloud service or self-hosted in a VPC, on-premise, or air-gapped.
