At Onsite Computing, we specialize in helping organizations run secure, reliable, and efficient IT environments without the stress. We provide both fully managed IT services and co-managed support for internal teams, backed by proactive monitoring, fast help desk response, and strategic guidance. A big part of what we do is cybersecurity, including cybersecurity monitoring, threat detection, risk assessments, and helping businesses meet compliance requirements like CMMC, HIPAA, PCI, and NIST. We also support cloud solutions such as Microsoft 365 and Azure, handle network infrastructure and servers, and build strong backup and disaster recovery plans to keep businesses protected. Beyond day-to-day support, we act as a trusted advisor, helping clients plan their IT roadmap, improve operations, and align technology with their goals. We work with a variety of industries including manufacturing, nonprofits, law firms, financial services, healthcare, and local government, bringing a local, hands-on approach that has defined our work in the Inland Empire since 2001.
