San Diego IT Support — 24/7 Helpdesk Response

San Diego IT support from DAG Tech means a 24/7 helpdesk with an 8-minute average response, engineers who already know your systems, and on-site visits from our downtown office when hardware needs hands-on work.
San Diego clients call about lab and office network issues, Microsoft 365 access, laptop failures, secure file sharing with partners, and escalations with carriers and software vendors.
San Diego has its own requirements: CMMC for the region’s large defense supply chain, CCPA for anyone handling Californians’ data, and wildfire and earthquake risk that can close offices. We plan for them with documented controls, offsite cloud backups, and secure remote access.

If you have IT staff, co-managed support adds 24/7 helpdesk coverage, security operations, and engineers to help with CMMC and audit work.
Outsourced IT fits San Diego organizations that need senior-level coverage without a full department, and it scales as you add labs, offices, or contract requirements like CMMC.

About DAG Tech IT Services in San Diego

DAG Tech provides managed IT services and IT support to San Diego organizations from our downtown office at 600 West B 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.

San Diego businesses sit under two demanding frameworks. The CMMC program requires defense contractors to prove NIST 800-171 controls to keep their contracts, and the CCPA requires reasonable security for Californians’ personal information. Biotech and healthcare clients add HIPAA. We build and document those controls through our IT compliance services service.

IT Services for Every San Diego Industry

We support biotech companies in Sorrento Valley, defense contractors in Kearny Mesa, tech firms in University City and Carlsbad, and law firms and healthcare practices downtown and in Mission Valley.
