After hearing about the Odo acquisition, I went to their website to learn more about them and their technology. To be honest, while I have heard the acronym SASE before I am not very familiar with it. So watching some product videos on Odo's site, it seems to me that there is a lot of similarity with web-based or SSL VPN portals that have been around for some time.
It appears that this is similar in that you would use a browser to navigate to a secure HTTPS portal, log in, and then be presented with a set of applications that can be tunneled through that HTTPS connection. This is a somewhat limited set of applications - things like RDP, web apps, etc. To access other types of applications or services (such as SMB file shares / mapped drives, and other Win32 client / server based applications) you would need to have SNX or a client based SSL (or IPSEC) RAVPN connection.
So, how does SASE differ from the traditional 'SSL VPN Portal', and can it address more traditional capability (ok, legacy maybe) that client based VPN connections can?
