US Continental has been a contract managed services client with Onsite Computing since 2013. We tried other IT companies in the past but Onsite was the only company that could do what they said they would do. They’ve recently setup the IT for our 2nd facility in Corona including our new VOIP phone system. They have also made us compliant new with PCI security standards that our bank required for credit card security. We highly recommend them to other businesses looking for a cutting-edge IT partner.
