Vicarius provides a unified vulnerability remediation platform called vRx that combines vulnerability management with automated patch management and compensating controls. The platform addresses patch management challenges by providing full-stack coverage across Windows, Linux, macOS, and thousands of third-party applications from a single console. vRx automates patch deployment based on configurable policies, uses risk-based prioritization incorporating CVSS scores, exploit prediction data (EPSS), and Known Exploited Vulnerabilities (KEV) to determine which patches to apply first. The platform includes a distinctive "Patchless Protection" feature that uses in-memory runtime shielding to block exploits when patches are unavailable or cannot be immediately applied, providing compensating controls for legacy systems or during maintenance windows. vRx also incorporates a scripting engine for non-patch remediation tasks such as configuration changes or service disabling. The platform provides centralized visibility and reporting for vulnerability status, patch compliance, and remediation progress across distributed environments including remote endpoints, cloud infrastructure, and IoT devices. Vicarius targets organizations struggling with high patch volumes, complex IT environments, resource constraints, and the need to reduce the time between vulnerability discovery and remediation.
