Features, pricing, ratings, and pros & cons — compared head-to-head.
Packet Capture (cStor®) is a commercial digital forensics tool by cPacket Networks. wireshark 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.
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.
Network engineers and threat hunters who need to inspect live traffic or troubleshoot connectivity issues should reach for Wireshark; it's the only tool that gives you packet-level visibility into exactly what's crossing your wire, without licensing costs or vendor lock-in. Deployed across virtually every enterprise network since 1998, Wireshark captures and decodes 900+ protocols natively, making it invaluable for NIST Detect work when you need to see what IDS alerts actually mean. Skip this if your team expects guided investigation or automated threat correlation; Wireshark requires expertise to read its output and won't tell you what to do with the packets you find.
