In their own words
SentryWire
SentryWire is a packet-capture appliance and network security monitoring platform for retaining and examining network traffic. It captures from 1 Mbps to above 1 Tbps and supports retention measured in weeks, months, or years. Distributed storage and compute enable searches across historical packet data, while forensic replay helps investigate traffic. Integrated Suricata IDS provides real-time detection and retrospective review. Analysis includes IDS search-back, BPF-syntax filtering, file-artifact extraction, JA3 hashing, GeoIP and ASN enrichment, Kibana dashboards, and display filters. Integrations named by the maker include Splunk, Elastic, Cisco, Palo Alto Networks, Fortinet, IBM, and Dell, with 25+ others supported. Deployment options include virtual machines, hardware appliances, portable systems, and cluster nodes; virtual machines capture up to 500 Mbps. SentryWire supports live capture, offline trace analysis, and PCAP files, and can retrieve packets from Splunk SOAR or Cortex XSOAR playbooks. Pricing is provided through sales contact.
Sniffnet
Sniffnet is a free network monitoring app for Linux, macOS, and Windows. It displays overall internet traffic statistics and real-time charts, and can show which programs use bandwidth. Users can choose a network adapter, filter observed traffic, and import or export PCAP capture reports. Sniffnet identifies local network connections, shows remote hosts’ geographical locations, and finds host domain names and ASNs. It recognizes more than 6,000 upper-layer services, protocols, trojans, and worms. Users can configure notifications for network events and import custom IP blacklists to highlight potentially dangerous connections. The app supports live capture, display filters, protocol dissectors, and offline trace analysis; it reads PCAPNG and CAP files as well as PCAP. Custom themes and 26 languages are available. The listed Sniffnet plan is free and the software is open-source under MIT or Apache-2.0. A 2025 security audit reported one low-severity finding, which had been fixed. Most functionality uses offline databases, while reverse DNS lookups provide hostnames for IP addresses.
