Last year AnyConnect went through an interesting transformation, its name changed to Secure Client, and looks like Cisco realized that the amount of information that could be collected from it and other services, makes it a good data mine for Security context and information.
But what is the buzz about, what changed? A few interesting things changed, and one of the most important things that changed was the way to deploy it or roll it out to an environment.
This one may seem a bit like a very involved configuration but in reality is not. The process is easy, if you know how to set up AnyConnect in an ASA, you will be able to crack it.
I have also included few links that show the process and the important things that you need to consider, as well as licensing requirements
