MCP is the Backdoor Your Zero-Trust Architecture Forgot to Close

Hi All

Just published in SC World: "MCP is the Backdoor Your Zero-Trust Architecture Forgot to Close"

This piece tackles a blind spot that is growing fast as organisations rush to deploy AI Agents. The Model Context Protocol (MCP) has become the connective issue of agentic AI ecosystems. But it was built for capability, not security. When you drop an MCP server into an environment that was built on zero-trust principles, you are introducing a component that bypasses nearly every control you spent years putting in place.

The article covers:

Why MCP breaks zero-trust assumptions at the architectural level
The specific attack surfaces: tool poisoning, privilege escalation, lateral movement via agent context
How the ContextGuard framework addresses MCP-layer visibility and enforcement
Practical controls security teams can apply today.

Welcome any thoughts from practitioners who already navigating MCP deployments in enterprise settings.

The conversation around security this layer is still early and needs more voices.

This is a very insightful article highlighting a critical but often overlooked gap in modern Zero Trust architectures. Articles like this are important reminders that Zero Trust is not a one-time implementation but an ongoing discipline that must adapt to new technologies. Great read and very thought-provoking..!
