Microsoft 365 managed IT · CSP licensing · Intune
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.
The home page asks you eight questions about your tenant. This page is the reference behind those questions — what actually gets touched, in what order, and where the licensing sits.
The three areas on this page
- Microsoft 365 managed IT — the tenant, day to day
- Microsoft CSP licensing — right-sizing and one bill
- Intune device management — enrolment, policy, compliance
Outsourced Microsoft 365 IT support, security, endpoint management, and licensing for small and mid-size businesses.

02 Microsoft CSP Licensing
Microsoft CSP licensing with support attached.
Buying Microsoft 365 licenses is easy. Buying the right licenses, keeping them assigned correctly, and pairing them with real tenant administration is where money gets saved. RTS helps SMBs right-size Microsoft 365 subscriptions and manage the stack behind them.
Waste gets found
We look for inactive users, over-licensed roles, duplicate subscriptions, and plans that do not match how the business works.
Licences map to real controls
Business Premium, Defender, Intune, and Entra ID features matter only when they are configured. RTS ties licensing to actual controls.
Tied to the tenant lifecycle
Licensing decisions are connected to onboarding, offboarding, groups, mailboxes, and device access so the tenant stays clean.
- Microsoft 365 Business Basic, Standard, and Premium guidance
- License assignment cleanup and unused-seat review
- Security-feature mapping for Defender, Intune, and Entra ID
- Monthly CSP subscription visibility
- Practical recommendations before renewals
- Support plans tied to your actual Microsoft footprint
- Business Basic
- Business Standard
- Business Premium
- Exchange Online
- Defender
- Intune
- Entra ID
- Teams
- SharePoint
- Add-ons
CSP licensing lets a Microsoft Cloud Solution Provider sell and manage Microsoft cloud subscriptions while helping customers choose the right plans and support model. You do not have to move licensing to start: RTS can start with an assessment and support plan, then move licensing only if it makes commercial and operational sense.
03 Microsoft Intune Device Management
Intune device management without enterprise overhead.
RTS helps small businesses bring Windows laptops and Microsoft 365 access under control with Intune, Defender, Entra ID, and practical endpoint policies. The goal is simple: know what devices exist, who uses them, and whether they are safe enough to access company data.
- Windows device inventory and enrollment planning
- BitLocker, Defender, update, and compliance baselines
- Conditional Access tied to device posture
- App and policy deployment for Microsoft 365 users
- New-hire and offboarding device workflows
- Plain-English reporting on unmanaged or risky endpoints
See the endpoints first
You cannot protect devices you cannot see. RTS starts by identifying endpoints, ownership, enrollment status, and business-critical users.
Policies sized for an SMB
We apply policies that reduce real SMB risk without creating brittle enterprise complexity.
Compliance feeds access
Device compliance can feed Conditional Access so company data is not equally available from every random machine.
Where to go next
