2021 Strategic Roadmap for SASE Convergence by Gartner
SASE has never been more relevant. The accelerated and sustained transition to work from anywhere has made converged cloud networking and cloud security a necessity.
Gartner, who first coined the term SASE in 2019, has further defined what SASE looks like today and in the future and the secret ingredient is Cloud. Some key takeaways from their SASE roadmap include:
- SASE security policy enforcement is dispersed in the cloud. This requires a software-based, hardware-neutral architecture deployed across multiple points of presence (POPs) with policy enforcement close to the point of consumption.
- SASE solutions are cloud-delivered, but vendors vary in the degree of “cloud nativeness” of their architecture. Legacy appliance and virtual appliance architectures need to be broken down into smaller, scalable components.
- Where physical SWG, CASB and VPN appliances are used, we advise enterprises move off these appliances at the soonest refresh possible and shift to cloud offerings.
