Reducing the risk without patching

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.

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.

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.

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.

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.

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.

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.
