Key Differentiators
- CoreSite's primary differentiators are its software-defined Open Cloud Exchange (OCX) platform—recognized as a Gartner 2023 Eye on Innovation Awards finalist—which enables on-demand, self-service multi-cloud connectivity through a single port without manual provisioning.
- The company positions itself as one of only a few providers in key markets (notably Silicon Valley) offering both a natively dense carrier ecosystem and wholesale-scale colocation on the same campus.
Industries Served

- The company also partners with Cloudflare via the Cloudflare Network Interconnect (CNI) program.
Company Size & Ownership
