Arkime vs Gigamon TLS/SSL Decryption: 2026 Comparison
Arkime is a free network detection and response tool. Gigamon TLS/SSL Decryption is a commercial network detection and response tool by Gigamon. 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.
Enterprise and mid-market security teams managing hybrid and multi-cloud traffic need Gigamon TLS/SSL Decryption because it's one of the few tools that actually decrypts encrypted traffic at scale without forcing you to choose between cloud and on-premises visibility. The platform integrates directly with GigaSMART intelligence and centralizes management across environments through GigaVUE Fabric Manager, giving your detection team the sight line they need when 80% of threats now hide in encrypted channels. Skip this if your infrastructure is purely public cloud and you're willing to accept blind spots in east-west traffic; Gigamon's strength is hybrid complexity, not simplicity.
