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

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

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."

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.”

Tal Shachar

Deputy Director, Infrastructure, EL AL Airlines

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."
