Ease and speed of connectivity impress and recommend
I have not found any areas that could be improved so far. I am not sure how Cisco IOS SSL VPN can continue their improvements for the future, but I think it is a great product. To stay on top, they probably need updates to this product. I do not know what kind of improvements these updates are offering. It is a great product so far.
