The CDOC Difference, Remote + On-Site, Together

Most IT companies make you choose: cheap remote-only support, or expensive on-site contracts. We think that's the wrong trade-off. Our model blends proactive 24/7 remote monitoring (we fix most issues before you notice) with real on-site presence in the Alliston area when hands-on work is needed. You get the coverage of an enterprise IT department at the cost of a small-business retainer.
