# Sealgate

> AI data leak prevention. Govern how AI agents access your data so you can adopt AI (Claude, ChatGPT, Cursor) and connect it securely to real data, without data leaks.

## What Sealgate Does

Sealgate is AI data leak prevention for agentic AI: one place to govern how every agent accesses your data. It sits between any AI agent (Claude, ChatGPT, Cursor, Copilot, etc.) and your organisation's data sources, so security, IT, and compliance can sign off on AI faster and teams can adopt it without data leaks. It provides:

- **Unified agent data access**: One control plane governing how every agent connects to your data sources
- **Runtime enforcement**: Deterministic policy controls at the tool-call level, not probabilistic guardrails
- **Session monitoring**: Real-time visibility into every agent action, data flow, and external service contact, with a live risk score on every action
- **Shadow MCP discovery**: Detects unauthorized tool servers the moment they appear on devices running the Sealgate daemon
- **SIEM integration**: Streams audit events to Splunk HEC or custom HTTP endpoints
- **Policy automation**: Auto-enforces company data policy, reducing IT tickets for agentic actions
- **Complete audit trails**: System of record for all agentic actions - who did what, when, and why

## The Problem Sealgate Solves

Traditional RBAC and data security break down with agentic AI. Agents connect to existing software via MCP/tools, bypassing access controls designed for humans. 59% of business and IT leaders say AI risks outpace their expertise. Sealgate gives security teams unified, deterministic control over agent data access, preventing data leaks while increasing AI adoption.
