Doors of IT helps organizations clean up, secure, migrate, and recover complex Microsoft identity infrastructure without turning every engagement into a generic IT project.
Clients do not need another vague IT provider. They need the right specialist door opened for the problem in front of them.

We specialize in Active Directory security, Entra Connect recovery, domain migration cleanup, SIDHistory risk reduction, delegation remediation, and identity infrastructure hardening.
Doors of IT is built around specialized Microsoft identity and infrastructure expertise. The goal is not to replace your helpdesk or become another generic MSP. The goal is to solve the complex work that gets risky fast: AD cleanup, Entra Connect recovery, migration fallout, SIDHistory, delegation, trusts, DNS/DHCP dependencies, and disaster recovery planning.
Review environment, goals, risks, and constraints.
Collect data, validate findings, and identify priority issues.
Build a practical remediation roadmap with change and backout guidance.
Support execution, validation, documentation, and next steps.
Start with a focused assessment, a migration cleanup review, or a targeted advisory call around AD, Entra, Semperis, recovery, or automation.
