Pcap Editing, Sanitizing & Anonymizing
all stacks, all layers

SafePCAP is a universal scriptable L2-L7 Pcap anonymizer, sanitizer, scrambler and full-stack editor. It allows for easy editing of packet capture data at any stack layer while fully preserving the packets integrity. Data modification at layers L2-L7 are done in a break-proof manner with the lengths, checksums, offsets and other service fields auto-recalculated for all affected protocol layers. Optional and conditional elements could be added/removed with a few clicks. A SafePCAP sanitized file can be analyzed as thorough as the original, but has sensitive data scrambled. Automation is fully supported via SafePCAP CLI.

Hundreds of protocol stacks are supported. Full support for all 3G/LTE 3GPP Mobile Core protocols and interfaces including SS7, RANAP, DIAMETER, and VoLTE. For example, the following command scrambles IMSI values by replacing German "262" MCC (Mobile Country Code) prefix with "310" (US):

What is SafePCAP good for?

  • Automated anonymization/scrubbing of pcap files
  • Building custom pcap files for firewall validation
  • Building pseudorandom pcap files for stacks fuzzing
Key Features
WYSIWYG Packet Editing

Visually edit a captured packet at any stack layer. Obfuscate any field. Add/Delete an optional field of the packet with a click.

Auto Dependencies Calc

Dependencies in the modified data are recalculated automatically. No worry about offsets, checksums, encoding, etc.

Total Automation

Automation is supported. To repeat a multi-step editing/scrubbing operation, run each step from a CLI in a batch file.

Frequently Asked Questions
What is the difference between SafePCAP and WireEdit?

Both tools are made by Omnipacket. WireEdit is a demo free to download/use for any purpose. SafePCAP is a commercial product. SafePCAP features and capabilities are a superset of WireEdit features and capabilities. The major additional SafePCAP features/capabilities: pcap-ng format support, native builds for Linux and OSX, large files (> 2 Gig), hundreds of additional protocols, fine-grained replace operations, higher speed of execution, programmability, CLI, faster bug fixing, enterprise level support.

What is the difference between SafePCAP and other packet editing tools?

You could think of SafePCAP as a Microsoft Word™ for network packets. All other packet editing tools are very limited in their ability to edit binary encoded stack layers above TCP/UDP. SafePCAP is the only full-stack packet editor by design.

What is the difference between SafePCAP and other Pcap anonymizers?

Other tools can't anonymize binary encoded stack layers above UDP/TCP. They take a simplistic approach of zeroing them out. This approach is far from ideal for some of the use cases. For example, it makes an effective analysis of anonymized 3GPP Mobile Core Pcap files impossible.

A popular opinion on the Subj is expressed here. It is indeed difficult to write software which allows editing of all fields at all stack layers without breaking packets integrity. SafePCAP supports it today.
