Sqrrl Data was founded by a trio of former analysts from the U.S. National Security Administration (NSA) with the goal of bringing the same level of defensive tools used by the NSA to the public. The program uses network traffic monitoring to identify advanced threats that many other programs miss or fail to identify as the grave threat they truly are. It requires no network taps to operate, gathering all the data it requires from three main sources, security data from things like SIEMs, DNS or proxy logs, and endpoint and identity data.”]
