Questions
Frequently asked
What does a Microsoft 365 security engagement include?
We assess your tenant against Microsoft and CIS best practices, harden identity and access with Entra ID and Conditional Access, tune Defender and data protection, and deliver a prioritized remediation roadmap with measurable outcomes—including an improved Microsoft Secure Score.
Do you help with cyber insurance audits?
Yes. We map your environment to the controls insurers require—MFA, privileged access, logging, email security, and backup—then close the gaps and assemble the evidence your underwriter needs to approve or renew coverage.
Do you offer ongoing administration, not just security?
We do. Beyond security, o7it provides day-to-day M365 administration: user and license lifecycle, Exchange Online, SharePoint and Teams governance, and proactive monitoring so your tenant stays healthy.
Where are you located?
o7it is based in Atlanta, GA and Denver, CO, and we work with clients remotely across the United States.
