There are a lot of cloud-based applications that are supported, such as Box, Skype, Google Drive, and SharePoint, but there are many more than have not been totally integrated. They cannot use in-house apps because they are not generic services. I would like to see support for custom applications. There are also certain storage services that are not integrated, like AWS S3. If the services are created by the customer then it would be very nice to have those protected too. Right now, this is a data at rest CASB, but it would be nice if it included features such as forward proxy or reverse proxy. It would be able to provide the OTP to those gateways and anyone who can integrate with Aperture can send the data to have it authenticated, via Aperture to the cloud, rather than just scanned. Essentially, if it can be made to act as an auth server, to automatically handle the forward proxy CASB, it would be good.
Overall it is actually very good. I haven't yet had any issue at all. One thing that would help is if we could get a guide. With Cisco, for example, you can just type the problem regarding your Cisco product and you will easily get your solution. In Palo Alto, however, it's not easy to find the solutions.
