Full Packet Capture Solutions for Incident Response
Full packet capture solutions for incident response provide security teams with complete visibility across network traffic. These solutions enable analysts to quickly investigate events, identify root causes, and respond effectively. SentryWire delivers the tools needed to strengthen defenses and reduce incident impact.
Unlogged Activity
Detection
In conjunction with enterprise log correlation tools (Splunk, ELSA, LogRhythm, etc.), quickly detect and sessionize network activity that may have been removed from log buffers prior to being written to disk.
Data Exfiltration
Detection
Log exfiltrated files with 5-Tuple indexing and hash details for comparing data, taking actions and retrieving sessionized PCAPs for forensics.
Indicators & Signatures Alerting
Multi-level signature and behavior event session search and logging, with visualization through DPI visualizer. Configure groupings of signature and unusual behavior alerts dynamically while in the fight, while real-time IDS alerting generates event logs for HTTP, Files, DNS, email, user agents, TLS/SSL, VoIP – all automatically correlated with PCAP and IPFIX flow records.
Phishing Preparation Detection
Detect and log all URLs traversing the network, from targeted phishing emails to web traffic, and alert when internal traffic accesses those URLs, automatically sessionizing the corresponding traffic for human validation and remediation.
Malware Infiltration
Detection
Detect, Classify and Extract objects (files, URLs, IP Addresses, etc.) in real-time to inspect and take appropriate actions to enrich cyber investigations and generate alerts.
FAQs
How does full packet capture improve the speed of incident response?
SentryWire accelerates incident response by streaming search results from PCAP files in near real time without impacting performance. Analysts can instantly locate packets across petabytes of data and replay full sessions, eliminating delays caused by correlating incomplete metadata sources.
Why is an extended packet storage timeline critical for incident response?
Extended packet retention is vital because intrusions often go unnoticed for weeks or months. SentryWire preserves network traffic for long periods, enabling forensic review of older data and complete investigations even when logs or alerts have expired.
What makes SentryWire's architecture different from other packet capture systems?
SentryWire’s distributed architecture removes performance and scalability limits found in legacy systems. It captures traffic up to 1 Tbps losslessly, stores over 100 PB of data, and preserves complete packets for full session reconstruction through an intuitive, web-based interface.
Can full packet capture help detect advanced persistent threats (APTs)?
Yes. SentryWire enables faster APT detection by allowing retroactive, signature-based searches on stored data. Analysts can uncover hidden threat behaviors using new intelligence, identifying stealthy “living off the land” activity that often evades endpoint detection tools.
How do organizations benefit from integrating SentryWire with existing tools?
SentryWire integrates with platforms like Splunk, Cribl, and Cortex xSOAR to visualize traffic and enhance monitoring. Its Suricata IDS and packet capture foundation provide deeper investigations and create correlation points for SIEM and SOAR systems, strengthening overall defenses.
What cost advantages does SentryWire provide for large-scale deployments?
SentryWire reduces packet capture and retention costs by more than half compared to legacy platforms. Its scalable design supports multi-terabit capture speeds, long-term storage, and real-time compression, making enterprise-scale forensic visibility both economical and sustainable.
