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

VP, Managed Technology & Services

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."

My favorite feature is Patchless Protection

"With Vicarius' vRx, I've never seen a patch that failed or had to be rolled back. We're saving quite a bit of time. Our clients using vRx haven't had any issues, and they've easily established patching for all their endpoints. "

Jeremy Herman

Security Engineer

Unified vulnerability discovery, prioritization, and remediation

"Vicarius streamlines vulnerability management between IT & Security by directly linking identified vulnerabilities to required patches, enhancing efficiency. The automation process has saved at least 30 percent of our manual tasks."

Wayne Ajimine

Patchless Protection is an incredible technology!

"vRx reduces the time customers spend on patching by reducing the overhead on the administrators, allowing them to do additional work. It saves time they would spend addressing the patching process, follow-ups, etc."
