1. Stacksona
Stacksona is a runtime governance layer that intercepts agent tool calls before execution and evaluates them against rules derived from your existing policies. Safe actions pass through automatically, policy violations are rejected outright, and edge cases — the $2,400 refund that needs a manager, the data export that requires sign-off — pause the workflow at that specific action while the rest of the agent state is preserved. The integration surface is real: JavaScript SDK, an MCP server, an n8n node, and a decision API, so it attaches to the agent stack you already run rather than replacing it. The ceiling appears when your policy logic requires context the governance layer cannot resolve autonomously — at that point, human review queues grow and the throughput advantage of automation narrows.

2. Axtary
Axtary sits beside the agent and evaluates each tool call against deterministic policy before the underlying provider is called. Routine actions — ones that clear the policy rules — pass automatically. Higher-risk actions pause for a human to review the normalized payload, and the approval is cryptographically tied to that specific hash. If anything changes after sign-off, the adapter catches the mismatch and blocks execution. Every attempt, pass, and rejection lands in a verifiable ledger. The self-hosted path keeps provider credentials local, which matters for teams that cannot route credentials through a third-party service.

3. Northbeams
Northbeams sits between your workforce and their AI tools, classifying what's running, blocking what shouldn't be, and generating the evidence chain your SOC 2 or HIPAA auditor will ask for. The browser-based agent installs without network changes, so IT doesn't need a procurement cycle to get visibility. Discovery is ungated, which means you can map your shadow AI footprint before committing to enforcement. The ceiling appears when your environment scales past a single site or when you need MCP agent governance — those capabilities are paid-only features. Teams running large multi-site deployments report that per-seat policy management becomes the operational bottleneck.
