VeriFIX by Itiviti

Automate testing and simulate FIX counterparties for rapid deployment.

Use VeriFIX by Itiviti to help automate the costly and error-prone process of manually testing your trading system. Reduce dependencies on counterparty test environments.

VeriFIX is the industry standard for comprehensive FIX testing and realizing significant efficiencies before “going live” with complex deployments.

Offers a range of benefits for buy-and sell side institutions including trading firms, brokerage houses, ECN and ATS venues, exchanges and independent software vendors. Quickly simulate environments to dramatically optimize the testing cycle using the market’s most robust, feature-rich testing and simulation tool.

Key benefits

The workflow is possible through VeriFIX, the FIX and proprietary protocol testing bridge between internal and external trading systems.

  • No programming or scripting language required, empowering all users across the development cycle.
  • Multi-session capabilities allow for the control of multiple sessions and simulation of many counterparties at once.
  • Scheduling and reporting capabilities optimize testing with overnight bulk regression suites.
