Full Packet Capture Solutions for Incident Response
Modern cybersecurity incidents require rapid and reliable access to complete network evidence. As a trusted leader in full packet capture and forensic-grade network visibility, SentryWire enables comprehensive network visibility, accelerates incident response workflows, and maintains forensic and compliance readiness.
Strengthen Your Incident Response with Full Network Visibility
Full packet capture gives organizations complete insight into network traffic. SentryWire records every packet, which provides analysts with a comprehensive record of activity during an incident. This level of visibility is essential for understanding behavior, identifying malicious actions, and confirming what occurred.
Complete Situational Awareness
Capturing every packet ensures that security teams can observe the full sequence of events. With accurate and unaltered network evidence, analysts can investigate suspicious traffic patterns, detect early indicators of compromise, and validate or refute anomalies. The availability of full packet data improves the precision of threat detection and strengthens the investigative foundation.
Faster Identification of Malicious Activity
Full packet visibility allows analysts to validate suspicious behavior, inspect payloads, and determine whether malicious content was delivered. This evidence accelerates investigative workflows and reduces time wasted on inconclusive alerts.
Real-Time Evidence Access
SentryWire provides immediate access to packet data during active security events. Analysts can retrieve any packet at any time and use it to trace a threat, determine whether a compromise is genuine, or confirm the absence of further malicious behavior. This capability supports rapid threat hunting and enables more confident decision-making during sensitive response activities.
Faster Containment and Remediation
Incident response solutions that include packet-level visibility shorten the time required to identify the scope of an attack. Analysts can verify all affected hosts, track lateral movement, and confirm whether remediation steps were successful. The ability to validate actions with original network evidence improves containment accuracy and ensures that threats are fully removed.
Extended Operational Clarity
Access to historical packet data also supports retrospective analysis. When new threat indicators or signatures emerge, analysts can search past traffic to determine whether the organization was previously targeted. This improves long-term situational awareness and helps refine defensive strategies.
Deliver Rapid, Accurate, and Forensically Sound Investigations
Full packet capture plays a key role in Digital Forensics and Incident Response. Raw network data offers the most reliable source of truth for understanding security events. When combined with network security monitoring, packet data forms an authoritative record that can withstand internal reviews and external audits.
Indisputable Evidence
Packet capture provides a complete and unaltered view of network activity. Investigators can replay sessions, review file transfers, and inspect payloads to determine exactly what occurred. This level of detail supports internal investigations and strengthens the organization’s ability to communicate findings to leadership.
Support for Complex Threat Scenarios
Full packet capture is particularly valuable when analyzing insider threats, unauthorized data transfers, and advanced persistent threats. Logs often fail to capture the full context of an incident. Packet data reveals the actual communications and interactions between systems, which helps analysts uncover the full narrative of an attack.
Improved Data Exfiltration Identification
SentryWire makes it possible to identify precisely what was taken during an exfiltration event. Analysts can inspect the transferred data, compare hashes, and validate the destination. This reduces uncertainty and provides a reliable basis for assessing the impact of a breach.
Strengthened Forensic Accuracy
Incident response solutions that rely on packet data provide much stronger investigative accuracy. Because packets are recorded in their original form, they offer clarity that cannot be obtained from logs alone. This ensures that findings reflect actual activity rather than partial interpretations.
