ISPsystem

ISPsystem develops software for server virtualisation, infrastructure management, billing and resource delivery. The company says it has built infrastructure-management platforms since 2004. Its current legal entity is registered in Cyprus, while its business has Russian origins. VMmanager, one of its products, centrally controls virtual machines and hosting infrastructure.

VMmanager sits above the individual systems it administers. Operators use that management layer to control virtual machines and the infrastructure beneath them. This central role makes network separation and access control lasting concerns for customers. ISPsystem advises operators to isolate management systems from virtualisation nodes and to restrict access through SSH. The platform's function, rather than any single incident, explains its security importance: access to the management layer can reach several customer systems through one administrative point.
