Frequently Asked Questions

What does a networking stack include?

Typically a LAN and WLAN access layer, WAN connectivity such as SD-WAN or VPN, perimeter and cloud security, monitoring tools and, increasingly, cloud and container networking. This hub groups directories by those layers.

What is the difference between SD-WAN and SASE?

SD-WAN manages and optimises connectivity between sites and clouds. SASE combines SD-WAN with cloud-delivered security such as secure web gateways, CASB and zero trust network access in a single service.

What is the difference between an API gateway and a load balancer?

A load balancer spreads traffic across servers, mostly at the network or transport layer. An API gateway sits at the application layer and adds authentication, rate limiting, routing and transformation for APIs. The comparison page covers where they overlap.

How does Kubernetes networking work?

Every pod gets its own IP address, and a CNI plugin provides connectivity and often network policy. Service meshes and ingress controllers then manage traffic between and into services.

Why use microsegmentation?

Microsegmentation divides a network into small zones with their own policies, so an attacker who compromises one workload cannot move freely to others. It is a core part of a zero trust approach.
