What follows is an overview of one of those techniques, K-means.

To validate an e-mail security stack's capability in blocking current real-world threats harvested from the wild, InQuest gathers unique malware daily and validates the common cloud e-mail providers (GSuite, O365). Collectively (stacked on top of one another), the providers' default security stacks are capable of detecting between 85% and 95% of these novel attacks. The samples capable of bypassing these stacks are candidates for the InQuest Email Security Assessment.
