In terms of areas for improvement in Cisco AnyConnect Secure Mobility Client, from my point of view, the solution works well and right now I don't see the need to improve it. Probably a better user interface could be created for Cisco AnyConnect Secure Mobility Client, but its core is VPN creation, and that works well, though I'm not a VPN specialist, and I'm not an expert on how to create a VPN, how the VPN gateway works, how it's implemented, and what's the architecture behind it.
A two-factor authentication feature was recently added to the Cisco AnyConnect Secure Mobility Client. In the past, you only needed to log in with your username and password, but now, there's a token, and the user interface for that token isn't that good. That's another area for improvement. Cisco should also make the two-factor authentication better in the solution.
What I'd like added to the Cisco AnyConnect Secure Mobility Client in its next release is a better two-factor authentication, in particular, the validity of the code being shorter because sometimes when I get the code and I add it to the client, it's invalid, though I'm unsure if it's centrally set up that way or if its a characteristic of the product.
Making the interface of the Cisco AnyConnect Secure Mobility Client more user-friendly is also what I'd like to see in the next release of the solution.
