Packet Capture (cStor®) is a commercial digital forensics tool by cPacket Networks. Workbench 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. Independent and vendor-neutral: we never sell rankings.
CST VerdictBased 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.
Security research and development teams building custom detection logic or automating forensic workflows will get the most from Workbench; it's free, Python-native, and scales without licensing friction as your team grows. The framework handles repeatability across investigations that commercial tools force you to log into a GUI to run, which matters when you're testing detection rules or building automation playbooks. Skip this if your team needs a polished UI or vendor support; Workbench assumes you're comfortable reading code and maintaining your own infrastructure.
