SentryWire review
A forensic packet capture platform built for long-term retention and retrospective investigation.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
SentryWire is an enterprise full packet capture platform for federal agencies, large organizations, and ICS/OT operators. It continuously captures complete network packets, applies real-time traffic filters, and supports retrospective search across stored traffic. Long-term retention is central to its positioning, with traffic retained for weeks, months, or years. The platform also combines network monitoring, forensic investigation, Suricata intrusion detection, packet replay, session reconstruction, file artifact extraction, hashing, and Kibana-based analytics.
The pricing model is contact sales, and the vendor promotes a free demo. SentryWire supports several deployment paths: virtual machines, hardware appliances, portable systems, and scalable cluster nodes. That range suits organizations with different infrastructure requirements, but it also makes deployment architecture an important part of the buying decision. Its ecosystem includes Splunk, Elastic, Suricata, Kibana, and Palo Alto Cortex, giving teams options for connecting packet capture, detection, analytics, and security workflows.
For investigations, the combination of continuous capture, long-term retention, retrospective search, and forensic replay is the main differentiator. Analysts can work with PCAP data, reconstruct sessions, extract file artifacts, and use hashing during review, while integrated Suricata detection adds an intrusion-monitoring layer. SentryWire is a strong fit when historical network visibility and detailed packet evidence matter across large or specialized environments. Teams seeking a smaller, simpler capture utility or transparent plan-based purchasing may prefer a narrower product.
