  • Dissectors for hundreds of protocols, so the packet contents are readable rather than hex
  • Display filters that cut a huge capture down to one conversation
  • Readable charts and per-host statistics rather than a packet list
  • Exports to PCAP so Wireshark can take over for the detail
  • Capturing on most systems needs elevated privileges or a driver such as Npcap
  • The interface assumes you already know roughly what you are looking for
  • Needs packet capture drivers installed, such as Npcap on Windows
  • Not a substitute for Wireshark when you need packet-level detail
