The Desktop Word Packet Processor

A Desktop Word Packet Processor
If you can decode it, you can edit it

WireEdit allows WYSIWYG editing of Pcap data in situ for any network stack at any stack layer while preserving the binary integrity of the data. Data editing is done in a break-proof manner with the lengths, checksums, offsets, and other inter and intra-packet dependencies recalculated on-the-fly for all affected packets and protocol layers.

Rent starting at $95.00/day

Frequently Asked Questions
What is the difference between WireEdit and other packet editing tools?

One could think of WireEdit as a Microsoft Word™ for captured network data. All other packet editing tools are very limited in their ability to edit binary encoded stack layers above TCP/UDP without breaking packets' integrity. WireEdit is a *full-stack* packet editor by design and as such fully preserves packets' integrity.

What is WireEdit license price?

WireEdit with IETF protocols support is $95/day (24 hours). Other packages/durations as well as site licenses are available. Contact us for more information.

Can I edit stack layer X at the network stack Y?

Short answer: By design if you can dissect X at Y, you can edit X at Y.

Install the latest WireEdit. No license is required. If you can't decode (dissect) the networking layer/stack of interest, let us know and we'll fix it. We can support any network stack.

No. Absolutely not.

Is WireEdit a Pcap editor?

Yes and much more. Pcap itself is just a simple packet data wrapper.

Can I edit a "reassembled" packet?

Yes. The changes made will be pushed to the fragments the packet has been reassembled from.

Does WireEdit support 3GPP Mobile Core Protocols?
