We’re pleased to announce that a new beta version of Imunify360, version 5.3, is now available. The following features are new in the v5.3 beta release:
Let’s review the changes in version 5.3:
We’ve greatly reworked Malware Scanner and made it ready for bulk operations. Optimized workflow for batches performs much faster as they can be grouped, and similar operations can be executed only once. That allows Imunify360 v5.3 to restore from the backup up to 100x faster and consume fewer resources for that.
Best seen on big restore-batches, which usually caused by the scanning with the “Try to restore from backup first” feature enabled or by manual “Try to restore clean version from backup” requests on big volumes.
Imunify360 v5.3 utilizes cgroups for the CPU and IO resource management during on-demand and background scans. It limits filesystem and CPU load according to configured “intensity level”, avoiding spikes and smoothly spreading the load.
That is useful for non-CloudLinux OS systems where LVE is not available. Earlier CentOS 7/8 systems required the CFQ scheduler to be available for the ionice priorities schedule. Now, Imunify360 v5.3 doesn’t depend on CFQ. Further installations on Debian systems will also rely on cgroups support for resource management.
Imunify360 is now capable of updating Proactive Defense protection rules in real-time. The new delivery system has a set of advantages:
The features previously marked as “experimental” have been tested carefully during several releases, and now they are ready for regular usage:
The new default settings will be applied to all new installations of Imunify360. The following features enabled by default:
