About DAG Tech IT Services in Chicago
DAG Tech provides managed IT services and IT support to Chicago businesses from our River North office at 515 North State Street. Clients get a 24/7 helpdesk with an 8-minute average response, managed cybersecurity, cloud managed services for Microsoft 365, Google Workspace, and Azure, and IT consulting, all on one flat monthly rate.
Illinois businesses face privacy rules with real teeth. The Biometric Information Privacy Act regulates fingerprints, face scans, and other biometric data and allows private lawsuits, and the Personal Information Protection Act requires reasonable security for personal data. Trading firms add SEC, FINRA, and CFTC expectations. We build and document those controls through our IT compliance services service.
