The installer summary of KATA ES describes what it does, in a way I don't see elsewhere.
(It does not say that I need a separate license to actually use it, so I would assume that I don't. If I need a separate license, it really should say so. (I still have no idea.))
The linked content is rambling, circuitous sales double-talk. "The solution is designed to help businesses implement an adaptive security strategy."
"For protection against targeted attacks and advanced threats, Kaspersky Lab offers Kaspersky Anti Targeted Attack Platform." (What is it part of?)
"Today, Kaspersky Lab launches two new enterprise solutions for preventing the most sophisticated cyberthreats..." (What does it come with or not come with? Is it purchased together or separately? Do I have it or don't I? How do I turn it on? How do I get it? What does it cost?)
"Kaspersky Lab's Anti Targeted Attack solution provides guidelines to help achieve realistic security goals and allocate appropriate resources, aligned with the existing – and future – business needs of enterprise security and SOC teams."
