Hear from our customers

From urgency to strategy

“Vicarius allowed us to step away from reactive patching and finally manage vulnerabilities with strategy instead of urgency.”

Anonymous IT Division Manager

EL AL secures global Patch Compliance

“Within two weeks we decided on Vicarius. Patch scheduling is now a one-day task instead of a full-time job.”

Deputy Director, Infrastructure, EL AL Airlines

Complete Vulnerability Remediation Platform

"What stood out was that it wasn’t just a scanner or a patch manager. It was an entire remediation platform. You discover vulnerabilities, prioritize based on real risk, and remediate automatically."

Eric Dowsland

Chief Customer Officer

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."

Anonymous Security Analyst

Security Analyst

Great patching capabilities, helpful dashboard, and excellent support

"vRx has saved us an incredible amount of time. We can just rely on the automated system and the schedules we've set. It's a huge time saver. It's saved us hundreds of hours."

Michael Cortez

Sr. Director of IT

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

Information Security Professional

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."
