Valuable resources saved

"Before vRx, we would spend countless hours manually finding and verifying patches. We saved so much time (and headache!)."

Anonymous IT Operations Lead

IT Operations Lead

Third-party software patching is the most valuable feature.

"We have automated third-party patching on specific software, improving efficiency by 80%. vRx has reduced our patching time, which has improved our operations. It is more robust than other solutions because it offers better third-party remediation."

Billy Turner

Single source of truth, capable of handling any application in our fleet

"vRx gives a single pane of glass to see what patches needed to go out and what sort of vulnerabilities we have on our Windows machines. Our meantime to remediate vulnerabilities has gone down by about 60% to 70%."

Peter Fallowfield

IT Manager

60% faster remediation, many hours saved

"Typically, with our previous solution of ManageEngine, it took about three hours to patch Windows Server, and now, that is less than an hour. It means less downtime for the business each month when we do patches."
