GuardRail is the system of record for DevOps with a robust configuration monitoring platform. Deep system scans compare the total state of a node to its previous states or to other nodes in the cluster. This regular scanning provides an overwatch against configuration drift that would otherwise be undetected. Additionally, GuardRail policies enable developers or administrators to specify the correct value for configuration items. Policies allow you to continuously validate your infrastructure and can be triggered from deployment tools to automate testing before and after a release.
