Cybersecurity: Threats and DefencesBackground
VMmanager 6 is ISPsystem's platform for centrally managing virtual machines, clusters and hosting customers' infrastructure. Hosting providers and infrastructure Teams use it to administer computing resources and offer customer self-service.
The platform sits beneath the guest servers it controls and can manage their disks and surrounding infrastructure. That position gives operators one control point for many virtual systems, while separating management activity from software running inside each guest. Actions performed at the VMmanager layer may therefore leave no process or altered file inside a customer's server. The product's role is administration of the virtualisation estate rather than an application installed separately in every guest system.
