AI Shield M99 vs Stacklok Enterprise MCP Platform: Side-by-Side Comparison (2026)

Stacklok Enterprise MCP Platform

Enterprise security teams deploying AI agents to interact with internal systems need governance that actually stops prompt injection and unauthorized tool access, not just visibility after the fact; Stacklok Enterprise MCP Platform enforces least-privilege access at the agent-to-system boundary through centralized policy controls, addressing the PR.AA and GV.SC gaps most platforms ignore. The platform logs every AI tool call and mediates MCP server connections, giving you audit trails that satisfy compliance while blocking risky agent behaviors before they execute. Skip this if your AI tooling is still experimental or siloed by department; Stacklok assumes you have multiple agents in production and need governance at scale.
