I don't understand much about the marketing droids speech on that web page but it reminds me of virtual coordinates estimation systems. Basically you take some measurements using a predefined metric between some hosts on the network, you calculate the virtual coordinates of each host to minimize the error between virtual distances and real distances and you can can instantly calculate a distance estimation between any two hosts. This is used in some experimental network monitoring systems like the Scalable Sensing Service (S^3). I have never heard of anybody applying it to detect malicious hosts but it could work I guess. You "just" have to choose a good metric for this purpose. Some virtual coordinates estimation systems include Netvigator [0] (used in S^3 [1]), Global Network Positioning (GNP) [2], Practical Internet Coordinates (PIC) [3] and Vivaldi [4]. Here [5] is a short comparison between GNP, PIC and Vivaldi with a discussion about the choice of the geometric space to use to model networks (see section 2.4, disclaimer: I wrote this).
