Features, pricing, ratings, and pros & cons — compared head-to-head.
Packet Capture (cStor®) is a commercial digital forensics tool by cPacket Networks. pcapfex is a free digital forensics tool. Compare features, ratings, integrations, and community reviews side by side to find the best digital forensics fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
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.
Incident response teams with limited budgets who need to extract files from pcap files during investigations should reach for pcapfex, a free tool that does one job without bloat. It's actively maintained on GitHub with 222 stars and requires no licensing overhead or integration complexity. Skip it if your team expects a GUI or needs to automate file extraction at scale; pcapfex is CLI-driven and built for analysts who prefer command-line forensics workflows.
