Full Packet Capture Appliance
SentryWire delivers an enterprise-grade full packet capture appliance that provides complete visibility into network traffic, both past and present. By capturing and retaining every packet at scale, the platform enables forensic investigation, incident response, and security-driven network monitoring across complex enterprise and regulated environments.
This full packet capture appliance serves as the foundation of SentryWire’s network security monitoring platform, enabling threat hunting, incident response, long-term forensics, and compliance-driven visibility across enterprise and ICS/OT networks.
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 as the Foundation of Network Security Monitoring
SentryWire’s full packet capture appliance is the foundational capability that powers its network security monitoring platform. By retaining complete packet data over extended timelines, organizations gain a definitive source of truth for detecting threats, investigating incidents, validating compliance, and supporting long-term forensic analysis.
Capabilities such as threat hunting, incident response, intrusion detection search-back, and ICS/OT network security all rely on the availability of high-fidelity packet data captured and preserved by this appliance.
Network security monitoring, threat hunting, incident response, and long-term forensic investigation all depend on the complete packet data captured and preserved by this appliance.
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 and retrospective analysis of suspicious traffic, enabling security teams to validate alerts and investigate threats using packet-level evidence.
Network Operations
Analyze network performance metrics derived from packet data to identify congestion, misconfigurations, and connectivity issues while maintaining a security-first monitoring focus.
Visualization & Analytics
Visualize network traffic and security events through interactive dashboards and Kibana integrations, supporting forensic analysis, anomaly detection, and investigation workflows at scale.
Artifact Extraction
Extract sessionized PCAPs and reconstruct file artifacts from captured traffic to support forensic analysis and evidence-based incident investigations.
Additional Platform Capabilities & Integrations
Software Updates: Continuous enhancements keep the full packet capture appliance aligned with evolving threats.
File Hashing: Extract and reconstitute file artifacts from packet captures via the Web UI.
JA3 Hashing & Threat Enrichment: Identify encrypted stream IOCs without decryption.
GeoIP & ASN Enrichment: Enrich metadata logs with location insights.
Enhanced Analytics via Kibana: Build dashboards for traffic anomalies and trends.
Statistical Baselining: Elastic-based analytics detect anomalies in network performance automatically.
Network Operations Analytics: In-browser packet analysis reveals congestion, DHCP issues, and connectivity problems.
Key Considerations for Deploying Full Packet Capture at Scale
Full packet capture provides unmatched visibility for security and forensic investigations and requires careful architectural consideration when deployed at enterprise scale. SentryWire is designed to address the operational challenges that have historically limited the practicality of packet capture in large and regulated environments.
Comprehensive Visibility
Full packet capture delivers an exact, replayable record of network activity by retaining complete packets rather than metadata or summaries. This level of visibility supports forensic investigation, threat hunting, incident response, and compliance validation using authoritative packet-level evidence.
Storage Efficiency and Long-Term Retention
Traditional packet capture systems struggle with storage costs and retention limits. SentryWire’s distributed architecture enables long-term packet retention using commodity hardware, allowing organizations to preserve weeks, months, or years of packet data without excessive storage overhead.
Search Performance at Scale
Large PCAP datasets are historically slow to analyze. SentryWire scales search alongside compute and storage, streaming results in near real time so analysts can investigate incidents and perform retrospective analysis without delays.
Operational Complexity
Raw packet data can be difficult to interpret without the right tooling. SentryWire integrates visualization, analytics, IDS search-back, and artifact extraction to streamline investigations and reduce the manual effort required to reconstruct events.
Enterprise and Compliance Readiness
By capturing both north–south and east–west traffic and retaining packet data over extended timelines, SentryWire supports audit requirements and regulatory mandates that depend on verifiable historical network evidence.
