Traditional networking and security concepts are obsolete when adopting the public cloud for digital transformation. SASE solutions by Barracuda Networks accelerate all-in public cloud initiatives by providing ubiquitous cloud access for every branch, access to the fastest global WAN backbone, cloud delivered security enforcement, and Zero Trust Access to any app for all remote employees.

Wide area networks (WANs) have played a critical role in business growth for several decades. Early WANs were used to provide mainframe access to remote terminals using networking protocols that were in place long before IPv4 came along. These networks were gradually replaced by WANs that used expensive point-to-point leased lines to connect local area networks across multiple locations. By backhauling traffic from branch offices to the data center, companies could centralize security resources in one location and avoid the overhead of distributed security appliances.
