Integrated systems combine server, shared storage and network devices, along with management software and support in a preintegrated stack. The integrated system market has four segments: integrated infrastructure system, integrated reference architecture, integrated stack system and hyperconverged infrastructure (HCI) segment. The overall HCI segment is further subdivided into Hyperconverged Integrated Systems (HCIS), which provides both software and hardware in an appliance model and the software only segment in which vendors provide the Hyperconverged software. This is then integrated with HW by a reseller or the end customer.

Identifying and investigating security events of interest 3. Supporting manual and automated response actions 4. Maintaining and reporting on current and historical security events
