Managed IT Services in California
Atlantic Computer Systems is based in the California Bay Area, and we support businesses and medical practices across Los Angeles, San Francisco, San Jose, San Diego, Sacramento, and statewide. You get HIPAA-first security, 24/7 monitoring, and a team that answers, without the wait or the surprise invoices.
Managed IT and security for California businesses and practices
Everything a growing organization needs to stay secure, compliant, and productive, under one partner.
Managed IT
24/7 monitoring and a responsive helpdesk, with patching scheduled around your hours.
Cybersecurity
Endpoint protection, email and ransomware defense, MFA, and dark-web monitoring.
EHR & EMR support
Epic, athenahealth, eClinicalWorks, and NextGen, with HL7/FHIR and lab integrations.
vCIO & IT roadmap
A technology plan tied to your growth and compliance calendar, reviewed each quarter.
Remote-first, with response that feels local
We are headquartered in the Bay Area and built remote-first, so California businesses get fast response without paying for a truck roll on every ticket.
Fast, human support
Most issues are resolved remotely in minutes, not days, by a consistent team that knows your setup.
Onsite when it matters
For hands-on work, our own team comes onsite as needed, billed per project, so a cable or a device swap is never a blocker.
Built for California medical and dental practices
California has more medical and dental practices than any state in the country, from the Bay Area and Sacramento to Los Angeles, Orange County, and San Diego. ACS supports them remote-first with managed IT services for healthcare, EHR expertise, and 24/7 monitoring, and comes onsite when hands-on work is needed.
California practices also answer to state rules on top of HIPAA, including the Confidentiality of Medical Information Act and CCPA privacy requirements, so we build HIPAA compliance and a documented risk assessment into onboarding and keep it current. Flat per-seat pricing means no break-fix surprises.
Getting started takes one call
No obligation, no jargon.
