PatchWalker is centralised, agentless patch management for Windows and Linux. It installs on one of your Windows Servers — which becomes your Controller — and manages Windows over WinRM and Linux over SSH, with nothing to install on your endpoints.
Installs on a Windows Server you nominate as the Controller. Free to use — donations welcome.
No agents to deploy or maintain. Enrol a machine and manage its updates, software, schedules and compliance from the web console on your Controller.
Windows over WinRM (HTTPS) and Linux over SSH. Nothing installed on targets — enrol and manage.
Windows Update and Linux package updates, plus third-party application and software deployment.
Recurring install schedules with maintenance windows and a per-schedule reboot policy.
A live dashboard, group compliance, CSV/print exports and scheduled compliance emails.
A built-in package mirror and contracts proxy bring Ubuntu Pro ESM to offline estates.
Role-based access, Microsoft Entra SSO, machine-bound secrets and encrypted backups.
PatchWalker is freeware — use it across your estate at no cost. If it saves you time, you can support its development.
