John Phillips, Cofounder

Within the increasingly complex information environments we operate in, the ability to detect and identify adversaries within the resident noise of the environment is difficult, SNOW provides Loki Labs with rapid insight at the point of compromise to quickly identify patient zero within an infection at a micro level and rapidly gain situational understanding of the scope and scale of an infection through macro level analysis. In addition, we have the ability to perform and execute response actions through the SNOW interface allowing for frictionless threat detection and response. Across current endpoint detection response suites SNOW is a best of breed solution for end-to-end threat characterization and remediation
