RC365 is R-Computer's managed IT and security division — built by the same Concord team that's been fixing, building, and now watching technology for Northern California businesses since 1986.
R-Computer didn't start as a managed services company — it became one, one client relationship at a time.
Founded selling custom-built computers out of a garage, R-Computer grew into a brick-and-mortar business offering full sales and service to home users and small businesses across Contra Costa County.
As clients grew from single PCs to full offices, R-Computer expanded into network design, custom-built systems, and on-site business support — earning long-term relationships with local companies and government agencies that in some cases have lasted over a decade.
R-Computer introduced remote managed services and cloud solutions, shifting from break-fix support to proactive management of client infrastructure.
RC365 brings that same local team together with continuous security monitoring, modern remote management tooling, and a dedicated NOC — managed locally and backed by trusted security partners for 24/7 coverage.
Every engineer is based in Concord. When you call, you're talking to someone who knows your setup — not a queue.
Monitoring exists so problems get caught before they interrupt anyone's day — that's the whole point of managed.
You'll never get a report you need a translator for. If we can't explain it simply, we haven't finished the job.
Many of our engineers have been with us 20, even 30 years. That's not a talking point — it's why we rarely have to ask twice.
Across four decades, RC365's client base has grown to include both private companies and public-sector agencies.
