Silent, deadly and constantly evolving, ransomware is never far from the headlines. You might expect McAfee to want to boast about its McAfee Ransomware Interceptor, then, but instead it's buried deep in the security company's website.
The likely explanation is that Interceptor is a ‘pilot’, more of an experimental tool than a fully supported product. The website warns you that it might have issues, which could be a concern for a low-level tool with such an important task.
McAfee provides few details on how the program works, other than it "leverages heuristics and machine learning" to identify threats, rather than using simple signatures.
