Vali Cyber ZeroLock is a hypervisor security solution designed to protect Linux-based hypervisors from ransomware and other attacks. The product operates without requiring kernel modules and works across multiple hypervisor platforms including VMware ESXi, Nutanix, XenServer, Citrix Hypervisor, Proxmox, Red Hat Enterprise Virtualization (RHEV), and KVM. ZeroLock provides multilayered defense through prevention, detection, and response capabilities. Prevention features include SSH multifactor authentication, application filtering, process behavior controls, network access controls, file access controls, canary files, and tamper protection. The solution uses configurable lockdown rules and policies that can be deployed across hypervisor environments. For threat detection and response, ZeroLock employs AI-based algorithms to identify malware in real-time, claiming detection efficacy above 98% for traditional and fileless ransomware. Response capabilities include automated file rollback, attacker persistence removal, and automated process tree creation. The system performs real-time behavioral analysis and can remediate attacks in milliseconds without user intervention. The product features an API-first architecture that enables integration with SIEM and SOAR platforms through syslog. Deployment is simplified through one-line terminal commands or partner portals like vCenter for VMware environments. ZeroLock operates with minimal resource overhead, requiring approximately 50MB of RAM. For VMware ESXi users, the solution is available as a signed VIB deployable via vCenter.
