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 large datasets and replay full sessions, reducing delays caused by correlating incomplete metadata sources.

Why is extended packet retention critical for incident response?

Extended packet retention is critical because intrusions often go unnoticed for weeks or months. SentryWire preserves network traffic for long periods, enabling retrospective investigation and complete incident response investigations even when logs or alerts have expired.

What makes SentryWire's architecture different from other packet capture systems?

SentryWire’s distributed architecture is designed for scale and sustained throughput. It supports lossless capture at high speeds, long-term storage at scale, and packet-level retrieval for full session reconstruction through an intuitive web-based interface.

Can full packet capture help detect advanced persistent threats (APTs)?

Yes. SentryWire supports retrospective, signature-based searches on stored packet data. Analysts can use new threat intelligence to hunt for previously unseen activity and validate behaviors that may evade endpoint or flow-based detection.

How do organizations benefit from integrating SentryWire with existing tools?

SentryWire integrates with SIEM, SOAR, and security analytics tooling to add packet-level evidence and context to alerts. This improves triage, supports faster validation, and enables deeper packet-based investigation when needed.

What cost advantages does SentryWire provide for large-scale deployments?

SentryWire is designed for enterprise-scale capture and retention with a cost-effective deployment approach. Its architecture supports high-throughput capture and long-term storage while reducing the total cost of ownership compared to legacy packet capture systems.

Does SentryWire replace incident response teams or managed detection services?

No. SentryWire provides the packet-level network data and forensic evidence that incident response teams rely on to investigate, validate, and respond to security incidents. It complements SIEM, SOAR, MDR, and endpoint tools rather than replacing them.

SentryWire’s architecture supports concurrent analysis and retrieval activity. Multiple teams can examine packet data simultaneously without slowing performance. This capability is essential during large or coordinated response efforts.

Maintain Compliance and Forensic Readiness

Compliance standards increasingly require organizations to maintain accurate and auditable records of network activity. SentryWire aligns with major frameworks and supports long-term evidence retention required to validate and execute an effective incident response plan.

Alignment with Key Standards

SentryWire supports compliance with NIST, NERC-CIP, OMB M-21-31, and resilience-focused guidelines from NIST, CIS Controls, and CISA. These frameworks emphasize stability, accountability, and evidence preservation. Full packet capture strengthens the organization’s ability to demonstrate compliance with these expectations.

Traceable and Auditable Network Records

Maintaining complete and auditable packet records supports internal and external assessments and strengthens documented response plans. Full packet capture allows organizations to review historical communication patterns, analyze sessions, and document findings clearly. This capability improves audit readiness and supports regulatory examinations.

Efficient Long-Term Retention

SentryWire simplifies long-term storage through detailed metadata and indexing capabilities. Analysts can locate and retrieve traffic from prior months or years without delay. This supports forensic investigations, compliance workflows, and long-term monitoring.

Legal and Operational Assurance

Packet-level evidence enhances legal defensibility by providing clear, objective records of network behavior. It strengthens operational accountability and supports continuous monitoring programs that rely on verifiable evidence.

Integrate Seamlessly into Your SOC and Security Ecosystem

SentryWire integrates with SIEM systems, SOAR platforms, and threat intelligence tools to provide packet-level context across security operations and SOC workflows. Packet data enriches alerts with verifiable evidence, improving automation accuracy and reducing false positives. Analysts can move through triage with greater confidence because alerts are backed by complete network visibility.
By correlating packet data with SIEM alerts, analysts gain a clearer view of both the event and its surrounding network activity. Teams can move quickly from detection to packet-level analysis to confirm behavior, identify root causes, and understand the full scope of an incident. This deeper correlation supports faster, more informed decision-making.
Packet-level visibility removes uncertainty at the start of an investigation. Analysts can immediately validate alerts without relying on incomplete logs or flow summaries, enabling rapid response, quicker containment, and more reliable remediation. This clarity helps teams respond faster while maintaining confidence that no residual activity remains.

Definitive packet evidence reduces prolonged or inconclusive investigations. Analysts spend less time chasing assumptions and more time confirming facts, while automated systems benefit from more reliable enrichment and correlation.
SentryWire runs on commodity hardware rather than proprietary appliances, delivering forensic-grade visibility at a lower total cost. This approach reduces long-term storage expenses, avoids vendor lock-in, and supports scalable deployments without sacrificing performance.

Why SentryWire for Incident Response

Effective incident response depends on complete, trustworthy network evidence, not assumptions based on partial data. As an incident response platform purpose-built for forensic visibility, SentryWire captures and retains full packet data so teams can validate alerts, reconstruct activity, and investigate incidents with confidence, even after the event has passed.

Designed for high-throughput, regulated environments, SentryWire delivers forensically sound packet evidence that supports audits, reporting, and post-incident analysis without relying on logs, flow summaries, or snapshots.
