Are you considering a move to the Gartner SASE model?

Whatever you choose, it’s imperative that you select a SASE approach that allows you to scale seamlessly (as flexibility and speed are one of the key hallmarks of this architecture)

You may only be worried about ZTNA/SSE today, but you have to think about the future. If you want to migrate your branches to an SD-WAN provider, does it make sense to onboard a second vendor - or should you just expand your SSE solution to include sites?

To me the choice is obvious

 As with many things in security, it depends. SASE, for example, includes SD-WAN, while SSE doesn't have SD-WAN. There are so many things to learn here. I've been spending a lot of time with SASE and SSE and would be happy to discuss the topic if anyone is interested
