Buying guidance
Networking equipment, explained
Every network is built from the same building blocks. Here is what each type of equipment does — and how to decide what belongs in your rack.
Firewalls & Security · 2
Firewalls sit at the network edge and control what crosses it — from simple port rules to deep inspection, VPN termination and content filtering on modern appliances.

Transceivers, line cards and expansion modules keep switch and router platforms flexible: the same chassis can serve copper or fiber, 1G or 100G, by swapping optics. Compatibility with your platform and the fiber type and distance are the deciding specs.

Routers connect sites to each other and to the internet, deciding the path traffic takes between networks. Branch and edge units handle WAN links, VPN and voice; larger platforms aggregate many links at once. Match the router to your WAN bandwidth and the services you run on it.
Browse RoutersSwitches · 34
Switches connect the devices inside a site — desks, cameras, servers, phones — and move traffic between them at wire speed. Access switches sit at the edge, often with PoE for phones and access points; core and aggregation switches tie the edge together. Settle port count, PoE budget and uplink speed first.

Access points bring the network to devices without cabling. Indoor and outdoor models differ in antennas and enclosures, and management is either cloud-based or via a controller. Coverage area, client density and PoE availability drive the choice.
