Automates device patching and vulnerability fixes

Action1 develops cloud software that helps IT teams manage device updates and remediate vulnerabilities across distributed organisations. Its platform uses endpoint agents and a browser console to identify missing patches, deploy operating-system and third-party application updates, and report deployment status. Administrators also use it for software deployment, inventory, scripting and remote desktop access, serving both internal IT departments and managed service providers. The business earns subscription revenue through per-endpoint licences, with hosted infrastructure replacing the need for customers to maintain their own patch-management servers. Founded in 2018, Action1 is headquartered in Houston, Texas.
