However, when it comes to blocking (either directly, or as part of a content filtering category), KISSmetrics is only blocked 27 percent of the time. That's interesting, because late last year, KISSmetrics settled a class-action lawsuit over complaints that they were "hacking users' computer software and browser tools to track their Internet activity without their knowledge."
AddThis, which isn't even in the top five of the most blocked tracking services, shares non-personally identifiable aggregated information with third-parties, Skyhigh said, without restriction. Yet, organizations seem to ignore this service in favor of services such as Kampyle, and Flag Counter.
This gap in filtering circles back to the original report, which pointed out that most IT departments are blocking applications based on brand popularity rather than risk. However, it could (and should) be argued that the risk is this case is larger for smaller organizations that cannot afford robust Web filtering. Also worth mentioning is the fact that some Web content filtering categories don't necessarily block everything, but only those known to the vendor, which alone can create problems.
