INSTEAD OF WIRESHARK

A lighter alternative to Wireshark for a quick look

For when the job is: See what is actually on this link right now.

Wireshark is the tool for analysing a trace, and nothing here replaces it. If you need a packet detail tree, a hex view, follow-stream, or to open a pcap somebody sent you, use Wireshark.

A lot of the time the question is simpler: what is on this link right now, and is the thing I expect to see actually there. CySecTek captures live on one adapter or every adapter at once, compiles your address, port and protocol choices into a BPF filter applied by the driver, and lets you change the application and keyword filters without restarting the capture.

What CySecTek does here

  • Capture on every adapter at once, which is useful on a laptop where you are not sure which interface the traffic is on.
  • Address, port and protocol filters compiled to BPF and applied in the driver, so the filtering happens before the packets reach the app.
  • Application and keyword filters that can be changed mid-capture without losing what you already have.
  • One-line summaries that identify common applications, DNS queries and HTTP request lines.
  • It is in the same app as the scanners and the terminal, so a quick look does not mean a second install.

When to keep using Wireshark

  • Reading or writing pcap files — CySecTek cannot open a trace or save one for someone else.
  • Packet detail trees, hex view and follow-stream.
  • Deep protocol dissection. Decoding stops at a one-line summary.
  • Anything you need to keep, share or analyse later.

Questions

Can I open a pcap file in it?
No. There is no pcap import or export. If you need to keep the trace or send it to someone, capture it in Wireshark.
What does it need?
The free Npcap driver and administrator rights, the same as any packet capture on Windows.
Can I change the filter without losing the capture?
The application and keyword filters, yes — they are applied after decoding. Changing the address, port or protocol filter reprograms the driver.
