The most valuable feature is being able to do centralized upgrades on the ASAs. We can literally go in and tick a bunch of ASAs - we have them grouped within their business uses. We can select all of those ASAs, and say, "Upgrade these ASAs at this scheduled time." It will copy down the ASA image, ASDM image, and then do the upgrade and failovers, and then put it all back into service as required at a scheduled time. It automates that process for us. We use the command-line tool quite a lot to push out bulk commands and changes to ASAs. That saves us a considerable amount of time. We have firewalls that are used for guest WiFi access. We try and maintain them as a standard policy. We can do that centrally and push that out. As for its security features around storing our firewall configurations in the cloud, I take it that it's secure, from conversations I had at the time. It's all encrypted on REST and in transit. That goes through our security team, who respond with that information. It doesn't concern me particularly because I know it's all encrypted. We also use two-factor authentication to be able to log in to the solution as well. Obviously, you need the user name and password, and you need the multifactor authentication key. That's built-in, we use the one that's provided by CDO, which is OneProtect. That works for rules. Everybody has their own login and I've got a full, change-management log view, so I can see who's done what changes. The other advantage we get from that is, if somebody makes a change and there happens to be an out-of-hours issue, the users can log back in and they can look at the changes that were made on that firewall, and they can roll it back by clicking a button.
