Global Connectivity via ECI Link


Asset managers are in constant communication with brokers, trading counterparties and other institutions throughout the financial services industry to purchase and sell securities. As a result, communication management can easily become complicated and inefficient.

That’s why we created ECI Link: a highly secure, redundant and available communications network for today’s buy-side firms. Eze Castle Integration’s ECI Link provides clients’ streamlined connectivity and communications to financial communities. ECI Link combines Internet, FIX, market data, business applications and voice connectivity over a converged, private network to power a firm’s trading operations.

The ECI Link Network

The foundation of ECI Link is Eze Castle’s ECINet private network which serves as the communications gateway for more than 500 buy-side firms and delivers highly secure and redundant Internet-based communication. ECINet features a full spectrum of Internet service capabilities that meet the immediate and future needs of hedge funds and investment firms.

Extending the reach of ECINet, Eze Castle offers direct connectivity to the SunGard Transaction Network (STN) and Ullink giving clients one communications platform to all of their trading counterparties, including broker-dealers, dark liquidity pools, crossing networks and other execution venues.
