What Fidelis Cybersecurity does
Fidelis Cybersecurity, operating as Fidelis Security, is a privately held US cybersecurity vendor founded in 2002 and headquartered in Bethesda, Maryland. The company sells an integrated detection and response platform — Fidelis Elevate — that unifies network detection and response (Fidelis Network), endpoint detection and response (Fidelis Endpoint), deception-based detection (Fidelis Deception), and Active Directory security (Fidelis Active Directory Intercept) under a single console with MITRE ATT&CK-mapped threat intelligence. A second platform, Fidelis Halo, extends the portfolio into cloud-native application protection through Server Secure, Cloud Secure, and Container Secure modules; this capability was acquired with CloudPassage in 2021.
The underlying technology is anchored by two granted US patents: Deep Session Inspection, which performs full session reassembly and protocol decoding for deeply nested files, and Heartbeat Monitoring, a microagent approach that offloads cloud security processing to a centralized grid. The platform analyzes 300+ attributes in real time and retains 360 days of metadata for retrospective analysis, which underpins the company's stated 9x faster post-breach detection metric. Integration partnerships with AWS, Azure, Google Cloud, Splunk, Palo Alto Networks, SentinelOne, Zscaler, and others allow the platform to operate as a connective layer across heterogeneous enterprise environments.
Fidelis sells exclusively through enterprise field sales and a channel partner ecosystem, with quote-based annual subscription pricing tailored to deployment scope. Customers are concentrated in US defense and federal agencies — the company states that 5 of 6 US military branches and 7 of the 10 largest US federal agencies are protected by Fidelis — alongside enterprise accounts in healthcare, financial services, pharma, biotech, retail, and IT. Revenue is generated through subscription licenses for the platform and modules, supplemented by professional services for implementation, integration, and managed detection support. The company has received growth equity from Marlin Equity Partners (2015 and 2018), and a follow-on growth investment from Runway Growth Capital and Skyview Capital in September 2022.
