Broadcom Inc. introduced VMware HyperArmor, a software solution designed to protect the VMware ESX hypervisor component of VMware Cloud Foundation against cyber attacks. The software closes exposure windows without disrupting the workloads that depend on the host.
AI-accelerated threats are growing in scale and sophistication, and the threat surface now extends across every layer of the infrastructure stack, including the hypervisor. Two problems account for most hypervisor attacks: stolen root credentials and unpatched vulnerabilities. HyperArmor addresses both, with support for VMware ESX 8.x and later releases.
HyperArmor provides virtual patching at the host layer, detecting and blocking attempted malicious actions on ESX host nodes before vulnerabilities can be exploited. The host-level capability complements the network-layer virtual patching that VMware vDefend provides for VMware Cloud Foundation. Because it requires no host reboots or software upgrades, IT teams can test and apply official patches on their preferred schedule.
HyperArmor protects the host without agents in guest virtual machines, allowing only what is ‘known good’ to run on ESX. The host runs a small, fixed set of processes, and HyperArmor establishes a positive security baseline that automatically blocks unauthorized executables and scripts. Multi-factor authentication for the ESX SSH login path requires standard SSH credentials followed by a time-based one-time password challenge tied to a separately defined identity.
“Frontier AI has changed the three V's of cybersecurity threats - the volume, velocity, and variety. When attacks come at machine speed, reactive detection and patching are no longer enough,” said Paul Turner, chief product officer, VMware Cloud Foundation Division, Broadcom.
“Attackers are using automation and AI to exploit infrastructure weaknesses faster than most organizations can patch, which means layered defense must extend all the way to the hypervisor as the foundation of the private cloud,” said Stephen Elliot, Group Vice President, Software Development and IT Operations, IDC. The product is described as reducing risk windows for security teams.
