MICROSOFT 365 MANAGED IT
Microsoft 365 managed IT services for small businesses.
Rosario Tech Solutions manages the Microsoft 365 stack your business already depends on: email, Teams, SharePoint, OneDrive, Intune, Defender, Entra ID, licensing, and helpdesk support. You get a technical operator watching the tenant, not a ticket dispatcher reading scripts.
Security baseline
Your tenant gets reviewed against practical controls that matter for SMBs: MFA, legacy auth, admin roles, device access, and risky sign-in patterns.
- MFA and Conditional Access
- Defender and identity posture
- Quarterly security reviews
Direct helpdesk
Users get clear help from someone who understands the Microsoft cloud instead of a generic call center queue.
- Email and Teams troubleshooting
- New-device onboarding
- Escalation-ready documentation
