Plango is a Mac-native security suite for people running AI coding tools. It uses a custom local security model to evaluate threats against the "lethal trifecta": data access, communication, and exposure.

You can restrict agent access by data type, such as SSH keys and env files, or by Finder tags. The security model runs on-device, and you can switch to another local agent or bring your own key. Plango also helps you review your Mac's privacy and access settings.
