cPacket Network Observability for Incident Response

cPacket powers real-time incident response with lossless packet capture, high-speed indexing, and seamless integration with SOC tools. Acting as the network’s digital black box, it enables rapid forensic analysis, root cause identification, and response automation across hybrid cloud, data center, and enterprise environments—ensuring cybersecurity teams can quickly investigate and neutralize advanced threats. cPacket emphasizes the critical role of packet capture in digital forensics, drawing a parallel to the black box in aviation to highlight its importance in understanding and preventing security incidents. Unlike other forensic methods, packet capture provides complete, tamper-proof context, showing the actual data exchanged during an attack. cPacket’s solution is designed to be pervasive, capturing packets from any point in a hybrid environment at high speeds (up to 200 gigabits per second), and scalable, capable of handling large data volumes while maintaining the ability to quickly index and retrieve relevant packets.

The architecture involves deploying monitoring points across the network, including cloud environments, where the same packet capture software is used as on-premise. This setup allows for centralized control and analysis, even in highly distributed networks. cPacket prioritizes ease of integration with existing security tools, featuring open APIs for seamless data exchange with solutions like DataDog and ServiceNow. Their focus is on providing the raw data and context that security teams need to conduct thorough investigations, rather than attempting to replace existing security systems.

A key capability is the ability to quickly retrieve and analyze captured packets, facilitating rapid root cause analysis and response automation. For example, when a third-party NDR solution detects an SQL injection, cPacket can provide access to the relevant PCAP data directly within the NDR’s interface, allowing security analysts to examine the attack payload and understand the full scope of the incident. This approach enables security teams to move beyond simply detecting threats to understanding their nature and impact, ultimately improving incident response effectiveness.
