The Challenge
“Threats Hide Where Conventional Tools Stop Looking”
Perimeter tools catch what they’re told to look for. Signatures, known patterns, flagged IPs. Attackers adapted to that model years ago. Today they come in through encrypted sessions and tunneled protocols, and once they’re inside, they move east-west across your network in ways most security stacks were never designed to see. An analyst might be staring at thousands of alerts and still miss the one that matters. By the time something looks obviously wrong, the attacker has usually been there for weeks.
Our solution
“Continuous Detection Across Every Port, Protocol, and Traffic Flow”
Powered by Deep Session Inspection®, Fidelis Network® analyzes full session content and metadata to uncover threats hidden inside encrypted and tunneled traffic.
Fidelis Network® pulls more than 300 metadata attributes from every session and builds behavioral context for normal traffic patterns using metadata analytics and threat intelligence. This is not a generic template. It is your network. Anything that breaks from that picture gets flagged, whether it’s moving north-south or east-west. From there, Active Threat Detection connects the dots across network, endpoint, deception, and sandbox data, maps it against MITRE ATT&CK, and gives your team something they can act on instead of another list to sort through.
- The moment behavior drifts from the baseline, on any port, any protocol, it gets caught. Detection happens in near-real time, allowing analysts to respond before attackers can move deeper into the environment.
- Instead of hundreds of separate alerts, analysts receive a single correlated finding: what happened, which assets were involved, and where it sits in the attack chain.
- Fidelis Halo® extends visibility into cloud workloads and hybrid infrastructure, ensuring attackers cannot disappear once they move beyond the network perimeter.
Why Now?
The Threat Landscape Isn't Waiting
44%
Ransomware was behind 44% of breaches reported in 2025. A year earlier that number sat at 32%. These attacks don’t work without moving through the network quietly first.
277 Days
The average breach lifecycle was 277 days in 2022. Get it under 200 and the savings average $1.12 million per incident.
21%
More attacks per organization in Q2 2025 than the same quarter in 2024. Seventy-one active ransomware groups were tracked that quarter. This is 58% more than the year before.
