Adversaries Hide

Public networks present a ripe environment for adversaries to prey on unsuspecting users. These networks often provide open connectivity that gives adversaries an easy foot in the door.

In minutes, Fidelis exposed two nation-state threat actors. With retrospective analysis, Fidelis confirmed the adversaries had evaded detection with existing tools for months!
