Can anyone share their experience with CATO networks or SASE solutions?

The term SASE is a moderately newly defined term by Gartner that at its heart combines networking-as-a-service with security-as-a-service in a single converged approach. The intent of SASE is effectively to simplify network communications, while providing a single context to work with.

Now as this is still an emerging technology, lots of vendors are approaching SASE in different ways. Some vendors will take multiple products and service chain them together, while other vendors will build their networking and security stack from the ground up to help unify and connect all the metrics in a single monitoring interface

The two main approaches here are ‘multi-vendor’ and ‘single-vendor’ SASE. I would highly advise single vendor as it provides a more consistent analysis of your traffic, and also offers a more streamlined approach to deployment and management. Andrew Lerner’s blog post (and attached single-vendor market guide) will be helpful here:

From my experience, people who have adopted a SASE architecture have found significantly reduced time-to-deploy, and have experienced a much quicker time-to-protect when it comes to security solutions.

It’s important to consider your current needs, demands and projected outcomes when it comes to a vendor, however SASE is the logical choice for the majority of organisations in the market.

I have deployed CATO netowks last years in more than 20 sites in three different continents (Europe, North America, Asia). The implementation  has been relatevelly easy and fast (more or less three months). I'm happy about the performance and the managment of the solution. I'm also very happy of savings (we have dismiss costly MPLS) 
I think the solution works well, my suggestion if want to adopt a SASE solution go all- in.
