Vali Cyber’s ZeroLock® provides hypervisor ransomware protection including virtual patching. Virtual patches can help organizations defend against the latest VMware zero-day vulnerabilities (CVE-2025-22224, CVE-2025-22225, CVE-2025-22226) as well as future similar vulnerabilities that may not have patches available for unsupported versions of ESXi. These zero-days allow attackers to execute code directly on the hypervisor, potentially giving them full control over your ESXi hosts and all workloads running on them.
In this video, Nathan Montierth, our Threat Intelligence Lead, breaks down why these vulnerabilities pose such a critical threat to ESXi infrastructures, why virtual patching is a critical tool to defend against these kinds of vulnerabilities, and how virtual patching works on ESXi with ZeroLock.
