Full Packet Capture for Threat Hunting
Full packet capture for threat hunting enables security teams to uncover hidden risks across network traffic. These solutions support proactive defense by identifying anomalies and advanced attacks. SentryWire provides the visibility and speed needed to detect and stop threats early.
Historical
Intrusions are almost never noticed or alerted on they happen.
Operational
Identify sharp increases or decreases in network traffic.
Legal
Assist Federal and Local Law enforcement agencies with investigations. SentryWire does not alter captured packets in any way allowing for a chain of custody to be established and used in legal proceedings as needed.
Strategic
Apply analytics and advanced statistical analysis to your network log data.
FAQs
How does full packet capture improve threat hunting compared to log-based monitoring?
Full packet capture provides tamper-resistant network evidence that attackers cannot alter, unlike logs that can be wiped or changed. SentryWire records full packets with payloads, enabling forensic replay and deep inspection that uncover threats missed by log-based monitoring.
What makes SentryWire's full packet capture especially effective for detecting hidden threats?
SentryWire enables retroactive, signature-based searches on stored packet data to find threats revealed by new indicators. It captures complete network conversations without truncation and integrates Suricata IDS for real-time alerts and long-term packet visibility, improving detection of stealthy adversaries.
How does SentryWire support retrospective threat hunting investigations?
SentryWire stores weeks to years of network traffic, allowing analysts to revisit packet data and search petabytes in minutes. Its extended retention supports long-term forensics, enabling full session reconstruction and artifact extraction through an intuitive, web-based interface.
What role does packet capture play in identifying advanced persistent threats (APTs)?
SentryWire enables faster APT detection by providing complete packet data across entire networks, even against zero-day exploits. Its full capture exposes “living off the land” techniques that evade endpoint tools, making it indispensable for comprehensive APT analysis and investigation.
Can SentryWire scale to meet the demands of enterprise threat hunting programs?
SentryWire scales to capture 1 Mbps–1 Tbps traffic with lossless performance using a distributed architecture. Its Hadoop-like design supports over 100 PB of searchable data while reducing costs by half, delivering enterprise-scale retention and forensic-grade packet visibility.
