SASE (Secure Access Service Edge) Planning and Design Guide
SASE (Secure Access Service Edge) Planning and Design Guide
In this whitepaper we explore:
- Dell’Oro Group previously published a white paper “Enterprise Networks at an Inflection Point: The Motivations for SASE”1, we described the motivations behind SASE (pronounced “sassy”).
- In this second paper, whose audience is the IT architect and the operations team, we delve deeper into SASE’s technical architecture, the vendor landscape, and emerging areas of vendor differentiation.
- We also compare and contrast do-it-yourself (DIY) versus a fully managed offering.
- We close by reviewing critical considerations in selecting a managed SASE service provider.
