Virtualisation Build
Review
Hardening assessment of hypervisor and virtualisation management platforms — VMware vSphere/ESXi, Microsoft Hyper-V, and Proxmox VE — covering management-plane security, VM isolation, and hypervisor attack surface.
A compromised hypervisor gives an attacker every guest running on it. Despite that outsized impact, virtualisation platforms are frequently hardened less rigorously than the workloads they host — management interfaces left broadly reachable, lockdown mode disabled, or service account privilege far wider than required.
Our virtualisation build reviews assess hypervisor and management-plane configuration against security best practices including CIS benchmarks and vendor hardening guides for VMware vSphere/ESXi, Microsoft Hyper-V, and Proxmox VE — covering host firewall configuration, management interface exposure, virtual network segmentation, and VM isolation controls.
Given the blast radius of a hypervisor-level compromise, findings here are weighted more heavily than an equivalent finding on a single guest — a management-plane weakness is treated as a whole-estate risk.
Scope & Baseline Selection
Confirmation of hypervisor platform, version, and cluster topology, and identification of appropriate benchmarks
Configuration Extraction
Collection of host and management-plane configuration via PowerCLI, vendor API, or SSH — covering host firewall rules, lockdown mode, NTP, logging, and certificate configuration.
Automated benchmark Analysis
Custom script comparison against CIS and other similar benchmarks across management interface exposure, host hardening, virtual network (vSwitch/vDS) segmentation, and VM isolation controls.
Manual Review & Attack Surface Mapping
Review of management network segmentation, service account privilege sprawl, snapshot and backup exposure, and shared storage access controls.
Risk Prioritisation
Findings that could enable hypervisor compromise, VM escape, or cross-tenant access are prioritised above all else, given the scale of impact a single compromised host represents.
Remediation Guidance
Custom guidance (including where appropriate, PowerCLI and Ansible remediation scripts) and a prioritised fix list aligned to your maintenance windows.
We weight hypervisor-level findings by their true blast radius — a management-plane weakness that could expose every guest on a host is never treated as a routine finding.
Remediation is delivered with practical commands and implementation guidance your infrastructure team can run directly — making it straightforward to translate findings into actionable changes.
