THE PERMISSION [LAYER]

Tools

AI agent governance tools

Products whose main job is governing AI agents and AI use: who an agent is, what it may touch, what data leaves, what it spends and what it did. Each entry says in plain words what the product controls and links to the vendor's own product page.

How the directory is kept

Every entry was checked against the vendor's own product page. Descriptions are ours and cover what the product governs, not what it promises. Availability is what the vendor states. Products that use AI agents to do other work, such as security operations, are left out unless they also govern agents.

The directory is reviewed monthly. New launches are listed on New tools, and a product with a launch in the last 90 days carries a Recent launch badge here. Vendors can send a product or a correction to [email protected]; a submission is read, never paid for, and does not guarantee a listing.

114 tools from 91 vendors in 13 categories. 14 with a recent launch. Last updated October 20, 2026.
