Based on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Trinity Cyber Full Content Inspection (FCI)
Security teams at mid-market and enterprise organizations running encrypted traffic will find Trinity Cyber Full Content Inspection most valuable for its ability to inspect and block threats inside TLS without the decryption tax that slows competitors; the sub-0.01% false positive rate means you're not drowning analysts in noise. The platform's 72 hours of searchable decrypted PCAP and threat hunting capabilities give you forensic depth that pure detection-only NDR tools skip. This isn't the tool for organizations still running mostly unencrypted traffic or those wanting managed SOC as their primary value prop rather than self-service threat visibility.
Security teams investigating encrypted traffic and multi-cloud network threats will get the most from Corelight Investigator because it analyzes encrypted flows without decryption and deploys sensors across hybrid infrastructure without forcing architectural changes. The platform covers 80+ application identifiers and includes ICS/OT protocol monitoring, addressing detection gaps that most NDR tools leave open. Skip this if your priority is automated response and playbook execution; Corelight prioritizes investigation and Tier 1 triage over containment workflows.
