Fidelis Network vs Arista NDR
Fidelis Network
Fidelis Network is the network detection and response (NDR) component of the Fidelis Elevate XDR platform from Fidelis Security. It uses the company's patented Deep Session Inspection technology to analyze traffic across ports and protocols, performing network traffic analysis, behavior anomaly detection, data loss prevention, and sandboxing. The product integrates with Fidelis Elevate endpoint detection and deception capabilities for correlated detection and response. Fidelis traces its origins to Fidelis Security Systems, founded in 2002, and has a documented history serving United States government and defense customers.
Pros
- Deep, content-level network visibility via patented Deep Session Inspection
- Integrates with endpoint and deception telemetry within Fidelis Elevate
- Holds federal certifications and contract vehicles relevant to government buyers
Cons
- Pricing is not publicly published and requires contacting the vendor
- Appliance and sensor based architecture can add deployment and tuning complexity
- Strongest feature value is realized within the broader Fidelis Elevate platform

Arista NDR
Arista NDR is a network detection and response platform that analyzes enterprise network traffic to discover entities, detect threats, and support investigation and response without endpoint agents. The product originated as the Awake Security NDR platform, founded in 2014, which Arista Networks acquired in 2020 and rebranded. Its components include EntityIQ for entity tracking, the AVA decision-support engine, and Adversarial Modeling for threat hunting. Sensors can run on Arista switches, as physical or virtual appliances, and in public cloud environments such as AWS and Google Cloud.
Pros
- Behavior-based detection with reported low false-positive rates
- Agentless deployment reported as fast to stand up
- Optional managed NDR threat-hunting service for lean teams
Cons
- Reviewers report occasional entity-resolution errors that merge unrelated devices
- Indicator-of-compromise ingestion is largely manual
- Query language has a learning curve for advanced searches
