CTI Technology

CTI Technology provides managed IT services, cybersecurity, and cloud support to businesses across Chicago, Elgin, and the northwest suburbs, including Aurora, Naperville, Schaumburg, and Hoffman Estates. Since 2004, we've acted as the outsourced IT department for organizations across Kane, DuPage, Cook, and McHenry Counties. Our services span managed IT, cybersecurity, Microsoft 365, cloud solutions, and responsive help desk support. We have particular depth serving Chicago-area law firms - building secure, compliant technology environments that protect client confidentiality, support attorney remote access, and meet the specific demands of legal practice. Most of our clients stay with us for years. Our recommendations reflect that continuity - proactive planning, honest technology assessments, and support that shows up when it matters most.
