  • Enforces policy and risk-based access on every AI tool call
  • Combines prompt-injection containment with PII obfuscation
  • Quarantines new MCP servers and streams audit data to SIEMs

Our verdict on SealGate

SealGate is a runtime security and data-loss prevention platform for organizations deploying agentic AI. It sits between agents and MCP tool servers, evaluating actions and applying policy to tool calls. Its controls are aimed at mid-market and enterprise teams that need oversight of agent activity, particularly teams governing MCP tool calls across endpoints. Deployment options include cloud, self-hosted, and desktop, with enterprise deployments also described for on-premises, VPC, and air-gapped environments.

The central capability is per-call governance: SealGate assigns risk and access-control levels, uses context-window-aware controls, and can hold actions for human approval. It also describes Lethal Trifecta prompt-injection containment and PII detection and obfuscation for tool results. For teams managing the MCP ecosystem, automatic quarantine of newly detected servers and connector dependency pinning and vetting extend controls beyond individual calls. This breadth is useful when the priority is containing agent actions and reducing data exposure; teams seeking a general-purpose security platform rather than agent runtime oversight may find its focus too narrow.

Agents connect through a streamable-HTTP gateway, with integrations for MCP-compatible agent frameworks and named tools including Claude, ChatGPT, Cursor, and Codex. Audit records and organization activity monitoring can be streamed to Splunk HEC or custom HTTP SIEM endpoints; Slack and Telegram are also listed integrations. Pricing is contact-sales, and the site offers a free try/demo flow. The published information does not establish a permanent free plan or a trial duration, so buyers should clarify terms directly. Email, community, and documentation are support channels. SealGate is a fit for organizations that want centralized runtime policy and monitoring; teams unwilling to route agent calls through a gateway should consider other approaches.
