TL;DR: On-Prem refers to hardware or software systems that are deployed, operated, and managed locally at the organization’s physical site.
On-Prem, short for on-premises, describes security infrastructure that runs entirely within the customer’s building or network instead of the cloud. This includes servers, NVRs, access control boards, storage devices, and other hardware managed directly by an internal IT or security team. On-prem setups give organizations full control over data, configuration, and maintenance but also require ongoing updates, physical security, and dedicated management resources.
On-Prem systems offer control, reliability, and isolated operation, making them essential for organizations with strict security, compliance, or data-governance needs. They require more management but provide maximum on-site ownership of infrastructure.
