Arkime vs Array NTB Series: 2026 Comparison
Arkime is a free network detection and response tool. Array NTB Series is a commercial network detection and response tool by Array Networks. Compare features, ratings, integrations, and community reviews side by side to find the best network detection and response fit for your security stack.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Security teams operating on-premises or hybrid networks with packet capture requirements should adopt Arkime for PCAP indexing and retrospective threat hunting; the open-source model means zero licensing friction at scale, and the tool's ability to ingest and search months of network traffic at line rate beats commercial alternatives on cost-per-terabyte. Arkime excels in the Detect function of NIST CSF 2.0, particularly for forensic investigation after an incident surfaces. This is not suitable for organizations needing real-time alerting, automated response, or managed service support; you're running it yourself.
Mid-market and enterprise security teams that need to extract signal from encrypted traffic without decryption will find Array NTB Series valuable, particularly when you're scaling network TAP deployments across hybrid infrastructure. The platform handles tunnel re-engineering and application-aware packet delivery at scale, covering both DE.CM continuous monitoring and PR.IR resilience functions, and supports both out-of-band and in-line modes so you're not locked into one architecture. Skip this if your team lacks the network operations expertise to manage centralized X-Tunnel orchestration between appliances, or if you need DLP and threat prevention baked in rather than monitoring-first design.
