I would be great if Sophos takes route what Zscaler or Netskope are taking. There is now need for cloud based Web GW integrated with rest of the product.

Since Sophos has already 80% of infrastructure for this, I guess it is possible to add this in way ZTNA works with these vendors, filtering, web browser isolation and adding cloud firewall within this swg ...
Now, we have to combine Central with one of these vendors which is adding management/integration issues.
