Configure a Linux server to automatically install critical security updates.
Automatically install critical security updates once per night so your servers don’t go unpatched for long periods of time.
Built-in random delay (between 0 and 30 minutes, by default) so all of your servers don’t update at the exact same time.
Supports Ubuntu 14.04, 16.04, and 18.04 via unattended-upgrades.
Supports Amazon Linux, Amazon Linux 2, and CentOS via yum-cron.
