Most enterprise WANs have historically used MPLS, but with the proliferation of cloud resources and mobile users, organizations are realizing the need to facilitate more flexible connectivity. They are faced with many options when making this decision, but one of the first that must be considered is whether to go with a hybrid WAN or SD-WAN.

Since the beginning of networks, the lynchpin of network security has been the firewall. The first network firewalls appeared in the late 1980s, and gained almost universal acceptance by the early 1990s. So what is a Firewall as a Service and why do you need it? FWaaS is a new type of a Next Generation Firewall.

Firewalls – the foundation of an organizations network security strategy – filters network traffic and can enforce an organizations security rules. By limiting the traffic that enters and leaves or enters an organizations network, a firewall can dramatically reduce its vulnerability to data breaches and other cyberattacks.
