Gateplex

Most agent governance strategies amount to writing everything to a log and reviewing it later — which means the bad action already happened. Gateplex takes a different position: it operates as middleware that intercepts agent actions at the moment of execution, evaluates them against configured policies, and enforces a block or approval before the action completes. The core workflow, as the vendor describes it, is intercept-evaluate-enforce: an agent attempts an action, Gateplex checks it against rules (spending limits, PII filters, duplicate transaction detection), and either passes or stops it. The audit trail is generated as a byproduct of that real-time check, not as a separate logging step.

The differentiating feature the vendor emphasizes is compliance-formatted evidence generation. For teams subject to EU AI Act obligations — particularly the transparency and high-risk system requirements — Gateplex produces audit artifacts structured for legal and compliance review, not just raw logs. That is a different output than what a general-purpose observability tool generates, and for procurement or finance agents making decisions that regulators may later scrutinize, the formatting difference is the whole point.

Gateplex fits best inside organizations that have already decided to deploy agents in regulated workflows and need a governance wrapper around them — not organizations still evaluating whether to use agents at all. Where it breaks: the platform is cloud-only, with no self-hosted option documented on the vendor page, which disqualifies it immediately for teams with data residency requirements that prohibit routing sensitive agent actions through external infrastructure. The free tier’s intercept cap also means teams with more than three agents or meaningful production traffic will hit the ceiling quickly.
