Reducing the risk without patching

Zero-days wait for no vendor. Legacy systems never get a patch. Production environments cannot afford a reboot. For every vulnerability that cannot be fixed on security's timeline, Vicarius closes the exploit path within hours, without touching the application.

Challenges

The Patch window is measured in weeks. Attackers move in hours.

A critical CVE drops. The vendor takes two weeks to ship a fix. IT schedules it for next month's maintenance window.

Some systems were never meant to be patched

Legacy operating systems, end-of-life applications, and OT environments have no patch coming. The exposure simply stays open indefinitely.

Change management protects uptime, not security

Formal approval cycles mean security cannot patch on its own timeline. The gap between finding a vulnerability and being allowed to fix it is where breaches happen.

Every unpatched CVE is a documented entry point

Attackers search for known, unpatched vulnerabilities. Each open CVE is a confirmed, searchable, actively targeted exposure waiting to be used.
Key capabilties

vRx is your full-stack remediation suite

Stop being held hostage by the patch cycle

Known exploits get closed the moment they are confirmed, not when the vendor or IT is ready.

Legacy systems stop being a liability

End-of-life servers, abandoned applications, and OT devices stop being open doors attackers can rely on.

The board stops hearing "We are working on it"

When protection does not depend on a patch, the answer to the board changes immediately.

Known vulnerabilities stop being easy targets

When exploit paths are blocked, a documented CVE with no patch stops being an attacker advantage.

Hear from our Customers

All in one platform

We chose Vicarius vRx for efficient third-party software patching, as Microsoft's solutions fall short. Though challenging for servers, it's effective for end-user devices. We value its patching ability but desire a cloud testing environment. We've considered alternatives, but vRx excels in support.

From urgency to strategy

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

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."

Valuable resources saved

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

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."

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

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."

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."

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."

Got Questions?

How can an organization protect itself from a zero-day vulnerability before the vendor releases a patch?

Vicarius vShield - Patchless Protection blocks the exploit path at the memory level using dynamic binary instrumentation within hours of a zero-day being confirmed exploitable. vIntelligence validates exploitability first using active exploit simulation, then vShield neutralizes the specific memory behavior the vulnerability uses, without modifying the application and without a reboot. The organization is protected before the vendor ships a fix.

What does patchless protection actually mean and how is it different from a compensating control?

Patchless protection blocks the specific exploit path a vulnerability uses rather than reducing exposure around it. A compensating control such as a firewall rule or network segmentation limits access to the vulnerable system but does not stop the exploit if an attacker reaches it. Vicarius vShield uses DBI to neutralize the exploitable memory behavior directly, confirmed by vIntelligence exploit simulation before and after deployment.

Can Vicarius protect legacy systems and end-of-life software that will never receive a vendor patch?

Vicarius vShield Patchless Protection works on legacy operating systems and end-of-life applications that vendors no longer support. Because protection operates at the memory level rather than through application modification, it requires no vendor involvement, no compatibility testing, and no scheduled downtime, closing exploit paths on systems the standard patch cycle will never reach.

Does vShield patchless protection require a reboot or cause application downtime?

vShield activates without a reboot and without modifying the application binary. It intercepts the specific exploit behavior at the memory level while the application continues running normally. Production systems, critical infrastructure, and operational technology stay online throughout, making it suitable for environments where any downtime requires formal change approval.

How does Vicarius handle vulnerabilities that have no patch and cannot be fixed with a script?

When a vulnerability has no vendor patch and no scriptable fix path, vShield Patchless Protection blocks the exploit path at the memory level until a remediation option becomes available. vIntelligence monitors the exploitability status continuously, so if the threat profile changes or a patch is eventually released, the security team is notified and can act with current information.

How does Vicarius confirm that patchless protection has actually closed the exploit path?

vIntelligence re-runs active exploit simulation after vShield deploys to confirm the attack path no longer works in the specific environment. This is not a theoretical check based on patch metadata. It is a live verification that the exploit behavior vShield blocked is no longer reachable, giving practitioners confirmed closure rather than assumed protection.

Does patchless protection work across Windows, macOS, and Linux including older versions?

Vicarius vShield Patchless Protection works across Windows, macOS, and Linux, including legacy and end-of-life versions that no longer receive vendor security updates. vRx agent and vRadar identify the affected assets across all platforms, vIntelligence validates exploitability in the specific environment, and vShield blocks the exploit path without a patch, without a reboot, and without application modification.
