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.

VPNs encapsulate data and encrypt the data using an algorithm contained within the transmission protocol. VPN traffic is encrypted and decrypted at the transmission and receiving ends of the connection. VPNs can also be set up using L2TP/IPsec protocols, which proves to have much stronger encryption than PPTP.
