ECI Auditor Profile

ECI is a global managed services provider headquartered in Boston, Massachusetts. Founded in 1995 as Eze Castle Integration, the firm rebranded to ECI and now employs more than 900 professionals across offices and data centers in the United States, United Kingdom, and Asia. It is a portfolio company of H.I.G. Capital.

ECI specializes in cloud, cybersecurity, and digital transformation services for mid-market financial services organizations, serving more than 1,000 hedge funds, private equity firms, venture capital firms, and asset managers. Its compliance-related offerings include cybersecurity risk assessments, SOC 2 readiness support, NIST Cybersecurity Framework alignment, and help responding to SEC cybersecurity requirements and investor due diligence.

ECI best serves small and midmarket investment firms that want managed infrastructure, security operations, and compliance support from a single financial-services-focused provider rather than assembling multiple vendors.
