The Financial Information eXchange (FIX) protocol ( is a standard electronic communications protocol for international real-time exchange of information related to securities transactions and markets.

The FIX standard defines a set of protocols which can be organized in two classes: ASCII protocols and binary protocols. This plugin (fix_sofh) implements a subset of the FIX standard based on the binary protocols. For support of FIX ASCII protocols, refer to the companion FIX4/FIXT plugin (fix4_fixt).

Please notice that this analyzer only supports a small subset of the FIX binary protocol. Its main intention is to detect FIX connections and do some basic validation, not to extract all possible fields.

Some of the protocol specifications supported by this analyzer include:

  • SOFH Session Protocol with SBE Encodings (detection and validation)
  • SOFH Session Protocol with GPB, ASN.1,FIXTV, FIXML, FAST, JSON, BSON Encodings (detection and validation)
  • Events: fix_sofh_detected(), fix_sbe_message()
