Vicarius vRx
Vicarius vRx combines vulnerability management with patch management, patchless protection, and scripting to remediate security findings. It prioritizes vulnerabilities using exploitability and environment context, and discovers endpoints, servers, network devices, IoT, and containers through agent-based or agentless methods. The platform advertises automated patch deployment across more than 20,000 third-party applications and operating systems. When a patch is unavailable, vShield offers in-memory protection for vulnerable applications, including legacy and end-of-life systems. vScript runs custom, community, and AI-generated PowerShell, Bash, or Batch scripts across Windows, macOS, and Linux. vRx can ingest findings from connected scanners and EDR platforms, route suggested actions for approval, and revalidate fixes after execution. It maps findings and remediation to frameworks including HIPAA, PCI DSS, Cyber Essentials, and more than 100 CIS Benchmarks. Basic is listed at $4 a month and Essential at $5 a month, billed per asset; each covers 100 workstations and servers. Both list a 14-day free trial. Custom pricing is scope-based and not listed.
