Packet Capture (cStor®) vs Trinity Cyber Full Content Inspection (FCI): Side-by-Side Comparison (2026)

Packet Capture (cStor®)

Enterprise and mid-market security teams investigating protocol-level incidents will find Packet Capture (cStor®) invaluable for its lossless capture at 10–200 Gbps paired with petabyte-scale persistent storage, letting you replay and forensically analyze traffic weeks or months after compromise. The onboard indexing and Wireshark integration mean you're not shipping raw PCAPs offsite for analysis; incident response happens at wire speed with full packet fidelity. This is deliberate forensics tooling, not a detection platform; if you need real-time threat hunting or automated anomaly flagging across the network, you'll want this feeding data to a separate NDR layer.

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.
