“We’re a cloud-first company, so we needed high-level expertise from an IT services team who could make all of our cloud-based systems work together. Xantrion gives us a virtual CIO. We [also] wanted to put more sophisticated IT processes in place to fend off hackers before they affect us, for both security and compliances reasons.”
