Mac

Transform static packet captures into a living, interactive network map. Netvis turns complex .pcap and .pcapng data into intuitive, animated topology graphs. Designed for students, IT administrators, and security professionals alike, Netvis eliminates the need for complex command-line tools and cryptic terminal filters, delivering instant visual clarity to network traffic analysis. Simply open a capture file to automatically discover hosts, map connection flows, and replay network events on a fluid, interactive timeline. # Key Features * Automatic Topology Mapping: Watch Netvis instantly group packets into clear connections and arrange hosts in an optimized, readable layout. The most connected devices are automatically centered, saving you hours of manual sorting. * Interactive Timeline Replay: Play, pause, scrub, or speed up your capture. Watch color-coded packet indicators move dynamically along connection edges to see exactly when and how data flowed. * Smart Host Discovery: Netvis automatically enriches host nodes with real-world context by parsing DHCP hostnames, mDNS local names, and identifying manufacturers using built-in MAC OUI lookups. * Deep Layer-7 Packet Inspection: Click any host or packet to explore color-coded, nested protocol layers (Ethernet, IPv4, ARP, TCP, UDP, ICMP, DNS, DHCP, HTTP, and TLS) alongside an integrated 512-byte Hex viewer. * Automated Anomaly Detection: Instantly surface critical network events without manual filtering. Netvis automatically flags port scans, host sweeps, DNS bursts, packet floods, and large downloads right upon import. * Persistent Customization: Save your host renames and custom device tags securely to your Mac, allowing your network profiles to persist across sessions and new captures.
