The traditional network security model, in which traffic is routed through the data center for inspection and policy enforcement, is for all intents and purposes obsolete. A 2019 study by research firm Gartner found that “more users, devices, applications, services, and data are located outside of an enterprise than inside.”
Driven by the adoption of multi-cloud infrastructure and applications, mobility and distributed workforces, the focal point for security has shifted to users and devices. As a result, the current data center-centric approach to network security is struggling to support a load it was not designed to bear.
This outdated architecture is impacting productivity and the user experience while increasing networking costs since more and more circuits and APIs are needed to move traffic in and out of the information technology vs computer science. Meanwhile, implementing various security functions on remote devices requires a complex and difficult-to-manage mix of endpoint software agents.
The writing is on the wall: security needs to move from the data center to the edge of the network. Bringing security inspection engines closer to entities (users and devices) eliminates the need for trombone traffic through the data center. Research firm Gartner calls this architecture a secure access service edge or SASE, and it provides several major benefits.
