About Eze Castle Integration

Serving regulated financial firms, especially alternative investment managers such as hedge funds, private equity houses and venture capital groups, ECI is a managed service provider. The firm trades under the name ECI, and it describes itself as a modern managed service provider that combines managed IT with artificial intelligence, automation and data governance. It says it has been in business for thirty years and runs offices in fifteen locations across three continents.

Managed IT services for regulated firms

The core service is day-to-day infrastructure support, with a network operations centre, a global private network and end-user IT help. The firm presents this round-the-clock support as the foundation on which its other services are built.

Microsoft, Cisco and Palo Alto Networks cloud platforms

ECI says it designs and runs cloud platforms built on Microsoft, Cisco and Palo Alto Networks technology, and that it handles the day-to-day administration of clients' Azure resources. It describes itself as a Microsoft Solutions Partner with advanced specializations, and it presents an end-to-end cloud management strategy as part of the service.

Cybersecurity and regulatory compliance

Security services include vulnerability assessment and remediation, governance and risk management, and a CISO as a service offering. The company publishes guidance on the cybersecurity rules the SEC has introduced for its clients and on the European DORA regulation for financial entities. It presents security, compliance and resilience as parts of one aim.

AI inside a controlled environment

ECI's AI offer is called ELLA, which the firm describes as a controlled environment where innovation and regulation operate side by side. It also helps clients adopt Microsoft Copilot, and it applies data governance across the service so that AI use stays within the client's rules.

Modernizing systems after two acquisitions

Systems and application modernization is a third area of work. The firm says its purchases of Alphaserve and NorthOut extended its range into managed IT, cybersecurity and business transformation, so it can move older applications onto current platforms as well as run them.

Platforms for hedge funds, private equity and venture firms

The company says it serves hedge funds, private equity and venture capital firms, which it describes as needing secure, scalable cloud platforms for trading and operations. It says its security work is meant to mitigate risk across different asset classes, and that its AI and data tools help investment teams draw insight from their information.
