Fidelis Deception is a proactive cyber defense solution that alters the perception of the attack surface by hindering an attacker's ability to move laterally undetected, distracting them with decoys and breadcrumbs, and trapping them at the deception layer. The solution automatically maps the cyber terrain, identifies asset vulnerabilities, and strategically deploys decoys based on real assets. It delivers alerts and events from decoys, AD credentials, poisoned data, and suspicious traffic. Organizations can create clones of their subnets and assets that can be populated with fake user accounts and directories and then lay down breadcrumbs for network discovery attempts, providing warnings when an adversary is on the network. Decoys, services, and associated breadcrumbs are deployed automatically, taking minimal system resources while acting as lures that attract adversaries. The solution runs without impacting operations or users and does not increase risk to data or resources. Fidelis Deception offers native connectors and open APIs to feed alerts, telemetry, and threat intelligence into SIEM, SOAR, or NDR solutions to detect, deceive and neutralize threats using deception technology. It shifts the advantage from the attacker to the defender by using decoys and lures to trap attackers in the deception layer, giving organizations time to detect attackers earlier, study their moves, and defeat them before damage occurs.
