Overview
PhiFIX is Sensiple’s end-to-end FIX and multi-protocol solution for brokers, trading firms, exchanges, and venues. It unifies FIX certification, automated testing, simulation, monitoring, and surveillance to manage the entire FIX lifecycle from a single platform.
Supporting FIX and protocols like FAST, ITCH, OUCH, and EMAPI, PhiFIX works across gateways, servers, and applications, fitting seamlessly into complex trading environments while providing clear visibility into message flows.
PhiFIX Engine
A high‑performance FIX engine purpose‑built for real‑time, secure financial message flow across trading counterparts.
PhiFIX Certifier
Drive conformance checks through configurable scenarios and rule sets that mirror your live order flows, making it easier to certify clients and venues in a traceable, repeatable way.
PhiFIX Test Suite
Run functional, regression, and performance tests against multiple gateways using predefined and custom test packs, helping you verify changes before they reach production environments.
PhiFIX Simulator
Simulate client or venue traffic, including different order patterns and conditions, to stress gateways and assess how your applications behave under various scenarios.
PhiFIX Surveillance
Track sessions and logs in real time, capture message streams, filter and search by key fields, and set up alerts to highlight unusual patterns or operational issues.
Why PhiFIX
Most trading organizations face growing complexity from new venues, counterparties, and regulations, making manual certification, custom testing, and basic log checks hard to scale and largely reactive.
PhiFIX replaces this fragmented approach with a structured, repeatable FIX management platform, combining guided certification, automated testing, session-level monitoring, and surveillance to reduce manual effort and enable predictable, well-governed electronic trading connectivity.
