SGNL delivers the missing control plane for AI, bringing continuous, real-time, context-aware access control to every MCP-enabled interaction

AI agents are proliferating across enterprises faster than security teams can govern—creating massive blind spots and risk. SGNL today announced that its Model Context Protocol (MCP) Gateway is live with private availability to customers. The release puts identity-first security policies in the path of every AI interaction, automatically blocking unauthorized actions while maintaining business velocity.

MCP is revolutionizing how AI agents interact with internal and external systems—enabling them to perform tasks, interact with data, and trigger workflows across the enterprise. But without robust access controls, these agents can operate unchecked, risking over-permissioned access and unintended data exposure. Because of this, enterprises have been hesitant to approve AI tools for their workforce.

SGNL’s MCP Gateway changes that. It brings centralized, dynamic authorization to every MCP server in the enterprise—governing access not just based on what the agent wants to do, but who they represent, where the request is coming from, and why it’s being made.

“SGNL's MCP Gateway delivers more than just a technical breakthrough,” said Stephen Ward, co-founder of Brightmind Partners, former Home Depot CISO, and ex-Secret Service cybersecurity leader. “It's a strategic game-changer that gives enterprises the levers to align AI automation with business policy in real time, bridging the critical gap between innovation and control.”

Eliminating blind access in the age of autonomous IT

AI agents are entering enterprise workflows faster than security teams can respond. From summarizing sensitive data to triggering downstream actions, they don't inherently understand risk, yet they operate at machine speed across dynamic contexts where traditional boundaries no longer apply.

This creates a fundamental mismatch. Legacy role-based access control was designed for predictable human behavior, not autonomous systems making thousands of decisions per minute. Enterprises can't simply "IAM harder" with existing tooling because static RBAC becomes exponentially more dangerous when applied to agents that never sleep, never second-guess themselves, and correlate data in ways humans cannot.

The result is blind access at scale, where broadly privileged roles and brittle permission matrices compound risk with every agent interaction.

The SGNL MCP Gateway addresses this head-on with:

• Real-time policy enforcement between MCP clients and servers
• Continuous evaluation of identity, device compliance, and request context
• Default-deny architecture with enterprise-wide MCP server registry that grants access only to approved services when explicitly justified
• Centralized MCP server registry and visibility into every AI agent interaction

“The Gateway isn’t just a feature—it’s foundational,” said Scott Kriz, CEO and co-founder of SGNL. “With it, we’re giving customers the ability to harness AI’s full potential without compromising on security and control. Our customers can now confidently adopt agent-based workflows knowing that access decisions are dynamic, contextual, and enforceable at every step.”

A real-world example: stopping data loss before it happens

In a common use case, an account executive attempts to use an AI agent to summarize Salesforce data from a non-compliant laptop. Without SGNL, the agent would retrieve and expose potentially sensitive customer data. With SGNL’s MCP Gateway in place, contextual policy enforcement blocks the request—ensuring that only secure, compliant actions are permitted.

This is just one of countless scenarios where real-time governance makes the difference between acceleration and exposure.
