Why Adopt a Live Patching Approach?

Accelerate Your Patching Timeline

TuxCare enables you to automatically deploy the latest CVE patches as they become available, so you can shrink your risk window and keep your systems secure – all without needing to reboot or schedule system downtime.

Eliminate the Hidden Costs of Maintenance Windows

Ensure continuous, uninterrupted service for your users by applying CVE patches while your systems are running – so you don’t need to announce scheduled maintenance windows.

Dedicate More Time to Other Critical Tasks

Say goodbye to your current drawn-out patching workflows and spend up to 70% less time patching CVEs so that you can focus more time on building innovative features and staying competitive.
