EndaceProbe vs netsniff-ng

EndaceProbe continuously records complete network packets, preserving network history for investigations into security threats, performance issues, and outages. It is offered as physical appliances and cloud or virtual deployments on AWS, Microsoft Azure, VMware, KVM, and Nutanix. Listed models sustain recording from 500 Mbps to 100 Gbps, with packet storage ranging from 1 TB to more than 3 PB. InvestigationManager provides centralized search and data mining, while EndaceCMS manages physical and cloud probes. Browser-based EndaceVision searches historical packets and includes hosted Wireshark decoding without downloading large PCAP files. The platform supports live capture, offline trace analysis, display filters, protocol decryption, and pcap, pcapng, and ERF formats. Endace lists Elastic integrations and an API for open-source, custom, and Fusion Partner tools. Appliances can host applications such as EndaceFlow. Security controls include hardened Linux, disabled shell access, authentication options, role-based access, and stated certifications. Pricing is available on request.

netsniff-ng is a free Linux network analyzer and toolkit for network development, debugging, analysis, auditing, and reconnaissance. It captures, analyzes, replays, and redirects traffic using zero-copy packet mechanisms, with live capture, command-line operation, display filters, and offline trace analysis. Supported capture files include tcpdump-capable pcap, a nanosecond-resolution tcpdump-capable variant, Alexey Kuznetzov's pcap, and netsniff-ng pcap. Low- and high-level filtering include Berkeley Packet Filter expressions. The toolkit combines netsniff-ng, trafgen, mausezahn, ifpps, curvetun, astraceroute, flowtop, and bpfc. Its dissector covers Ethernet, WLAN, ARP, MPLS, VLAN, LLDP, IPv4, IPv6, ICMP, IGMP, TCP, and UDP. Mausezahn and curvetun are experimental and not advised for production. The toolkit is GPL 2.0 open source. Release checks use Git tags and GPG signatures; support is through a mailing list and online FAQ.
