The widespread adoption of Software-Defined Wide-Area-Network ( SD-WAN ) in recent years has caused many to wonder whether WAN optimization is still necessary. More specifically, t he rise of WAN optimization began around 2004 and addressed the limitations of the limited capacity of costly MPLS and leased line connections.

Since the release of Gartners Market Guide for Zero Trust Network Access (ZTNA) last April, ZTNA has been one of the biggest buzzwords in network security, and for good reason. A policy of zero trust helps enterprises limit exposure to the myriad of threats facing the modern network. Lets find out.
