Endpoint
Also known as: End Device, Client Device
An endpoint is any user-facing device that connects to a network — laptops, desktops, smartphones, tablets, and workstations. In security contexts, endpoints are the primary targets of attacks and the focus of EDR and MDM solutions.
"Endpoint" distinguishes user devices from network infrastructure (switches, routers) and servers. The term is particularly prevalent in security, where endpoint protection — antivirus, EDR, MDM policy enforcement — is a distinct discipline from network security.
Every endpoint is a potential entry point for attackers: a phished credential, a malicious download, an unpatched vulnerability. EDR (Endpoint Detection and Response) provides behavioral monitoring and response capabilities on each device. MDM enforces security policies: disk encryption, screen lock, patch status, VPN requirements.
The shift to remote work expanded the endpoint security challenge: devices now operate outside the network perimeter, on untrusted networks, without the protection of on-premises firewalls and filtering. Zero Trust treats each endpoint as potentially compromised regardless of network location — verifying device health at every access request rather than trusting based on network position.
In infrastructure terms, endpoint count drives switch port planning, network addressing, access-control rollout, and PoE power budgeting.
