SASE (Secure Access Service Edge) is a cloud-native technology that establishes network security as an integral, embedded function of the network fabric. SASE supplants legacy services offered by single-purpose point-solutions located in location-locked corporate premises such as data centers.
Gartner’s “The Future of Network Security Is in the Cloud” research reports that in the digital economy security focus shifts from the data center to the identity of the user/device in conjunction with the data context of the communication session. Legacy security overlay solutions fail to provide the agility, flexibility, connectivity and security required in the network fabric that weaves together the digital economy: cloud-native, mobile, everything-connected.
Gartner expects that by 2023, 20% of enterprises will have adopted SWG, CASB, ZTNA and branch FWaaS capabilities from the same vendor, up from less than 5% in 2019. And by 2024, at least 40% of enterprises will have explicit strategies to adopt SASE, up from less than 1% at year-end 2018.
