Complete
Full Packet Capture Appliance
SentryWire delivers advanced full packet capture appliances that give enterprises complete visibility into network traffic, both past and present. With forensic-grade data at unmatched speed and scale, organizations can troubleshoot issues, investigate incidents, and strengthen defenses with confidence.
Overview of Our
Full Packet Capture Appliance
SentryWire offers full packet capture solutions and appliances designed for enterprises that require forensic visibility across massive, complex networks. Its distributed architecture eliminates the performance, scalability, and cost limitations of legacy systems, capturing traffic at speeds from 1Mbps to +1Tbps while retaining it for weeks, months, or even years at less than half the cost of competing platforms. Unlike metadata-only monitoring or packet sniffers, SentryWire records complete packets, headers, and payloads, enabling accurate packet analysis and replay.
Unlike traditional single-server tools, SentryWire scales compute and storage seamlessly, delivering lightning-fast searches across 100+ PB of network packets. The platform combines high-speed recording with real-time filtering, visualization, and advanced BPF-syntax analysis. Integrated packet analyzer functionality and network monitoring dashboards allow teams to troubleshoot performance issues, investigate suspicious protocols, and accelerate root-cause analysis.
With extended retention timelines, SentryWire ensures packet data remains available long after most tools have aged out. This matters because state-sponsored intrusions often remain undetected for more than 146 days. Without a high-fidelity packet record, enterprises can’t answer critical questions: when attackers entered, how they moved laterally, or what data was exfiltrated.
Full Packet Capture
Unlike packet sniffers that only inspect headers or metadata, SentryWire captures complete network packets for forensic replay, deep packet inspection, and long-term analysis.
Powerful & Fast Search
Scale searches with compute and storage, streaming results from PCAP files in near real time without slowing down network performance.
Extended Timeline
Retain network traffic for weeks, months, or even years, ensuring analysts can revisit packet data long after most tools have aged out.
Fast Capture Speed
Capture at line rates from 1Mbps to +1Tbps with lossless performance, even during the burstiest network activity.
IDS Search Back
Use intrusion detection signatures to retroactively search stored packet data, identifying threats that only became known after capture.
Intrusion Detection
Integrated Suricata IDS provides real-time detection, network monitoring, and rule-based analysis of suspicious traffic patterns.
Network Operations
Generate logs and analyze network performance metrics, helping teams resolve connectivity issues, congestion, and misconfigurations faster.
Visualization & Analytics
Access interactive dashboards and integrate with tools like Kibana to visualize network traffic, monitor performance, and track anomalies.
Artifact Extraction
Retrieve fully sessionized PCAPs and extract file artifacts directly from captured packets via the web interface.
Overview
SentryWire is a Full Packet Capture Appliance and Network Security Platform designed to give security and IT teams hands-on visibility into their networks. Unlike metadata-only approaches, it records every packet — headers and payloads, to create a replayable record of activity. This allows analysts to reconstruct sessions, investigate anomalies, and know with certainty what occurred during any incident or performance issue.
Built on a scalable, distributed architecture, SentryWire ensures no packet is lost, even at speeds from 1Mbps to +1Tbps. Analysts can filter and search data in real time, sessionize PCAPs, and extract artifacts directly from the UI. By combining high-speed recording with analytics and visualization, SentryWire shortens mean time to resolution (MTTR) for both security events and network troubleshooting.
More than a capture engine, SentryWire integrates with SIEM platforms, supports IDS signature search-back, and provides dashboards that track performance metrics such as latency, congestion, and bandwidth utilization. This empowers practitioners not only to detect intrusions but also to validate zero-trust policies and monitor user experience. For teams that need actionable insights as well as forensic depth, SentryWire is the packet capture tool that delivers both.
Understanding Packet Capture
Metadata and Flow Data - Why Full Packets Matter
Metadata: Useful for summaries but cannot fully reveal payload contents or attacker techniques.
Flow Data: Shows who was talking to whom, but not what was said.
SentryWire combines the benefits of flow visibility with the depth of full packet capture, giving IT and security teams a complete picture and eliminating blind spots that attackers exploit.
Security, Compliance, and Zero-Trust
Packets form a verifiable, tamper-proof record of network events — ideal for digital forensics, compliance audits, and regulatory investigations. SentryWire strengthens zero-trust environments by validating exactly what resources users and systems accessed, helping close gaps in policy enforcement.
Performance and End-User Experience
Packet capture is not just about security — it is a powerful performance monitoring tool. By analyzing response times, retransmissions, and other KPIs, SentryWire helps administrators pinpoint slow applications, misconfigured devices, or latency-inducing network changes. This back-in-time data supports before-and-after comparisons during upgrades, ensuring service improvements actually deliver measurable gains.
What is a Packet Analyzer
A packet analyzer is a tool that interprets captured packets, displaying header and payload information to generate actionable insights. SentryWire’s platform goes beyond basic analysis by sessionizing traffic, correlating logs, and integrating with SIEM tools — simplifying workflows and reducing mean time to resolution (MTTR).
