BullWall Launches Virtual Server Protection to Combat Ransomware Attacks on VMware Environments

VEJLE, Denmark & WILMINGTON, Del., March 17, 2025 – BullWall, a leading provider of ransomware resilience for critical IT infrastructure, announces the launch of BullWall Virtual Server Protection (VSP) for VMware, a cutting-edge solution designed to safeguard organizations against the escalating threat of ransomware attacks targeting VMware vSphere and ESXi platforms.

As cybercriminals increasingly exploit vulnerabilities in virtual environments, ransomware attacks on VMware ESXi servers have surged, with average ransom demands reaching $5 million per attack in 2024. BullWall VSP is a first-of-its-kind security solution that prevents unauthorized access and encryption attempts on ESXi hosts, ensuring businesses remain resilient against cyber threats.

“The rising number of ransomware attacks on VMware infrastructure is a wake-up call for organizations worldwide,” said Jan Lovmand, BullWall CTO. “With BullWall Virtual Server Protection for VMware, businesses can proactively defend their critical infrastructure against unauthorized access, encryption, and data exfiltration.”

According to the IT Director at a large UK Hospital, “the Bullwall component for VMware ESXi is very impressive and provides immediate protection for one of our biggest concerns – an area of our infrastructure we have been unable to protect until now. The added MFA protection for login on ESXi hosts via SSH provides protection against access and encryption from the outside which we didn’t have and considered a weakness in our defense.”

Key Features of BullWall VSP for VMware

Multi-Factor Authentication (MFA) for SSH logins – Prevents unauthorized access and exploitation of admin privileges.

Real-time threat detection and mitigation – Continuously monitors running processes and files for ransomware activity.
