Fidelis Cybersecurity is the leading provider of automated threat detection and response solutions that span across networks, endpoint and cloud environments. With Fidelis you can:

  • See across all ports and protocols, and discover all network assets, endpoint activity and lateral movement
  • Analyze all network and endpoint metadata using threat intelligence, machine learning and sandboxing
  • Detect attacks in real time AND retroactively over the entire kill chain – from initial infiltration to lateral movement to data theft
  • Disguise your network with deception to delay attackers, detect insider threats and lure adversaries away from your assets
  • Automate incident response to rapidly triage alerts, jumpstart playbooks and terminate attacks already in progress

If you’re looking to shift from a prevention-focused approach to a strategy that prioritizes detection and response, we’re happy to answer any questions you may have. Simply complete the form and we’ll reach out to you shortly.
