Azure Managed Service Provider — Microsoft-Native Cloud Operations

The three labels overlap, but each answers a different question. A Microsoft managed service provider operates the whole Microsoft stack, with Microsoft 365, identity, devices and security at the centre and Azure as one part. An Azure managed service provider runs Azure infrastructure and platform services: virtual machines, AKS, databases, networking, backup, security operations and cost. A CSP partner resells Microsoft licences and subscriptions under Microsoft's Cloud Solution Provider programme. Many MSPs are also CSPs, but licence resale on its own is not a managed service.

Opsio is an Azure managed service provider: we run Azure infrastructure, Entra ID identities and Azure security operations, integrated with your Microsoft 365 tenant. If most of your pain sits in Microsoft 365 and endpoints, ask any provider — including us — to show the named people and runbooks for those areas, and one incident process that covers both.

Contracts differ most at the edges. Use this as a starting checklist when you compare proposals: the first part of each line is normally in the monthly fee, the second part is often extra or a separate project.

Most mid-sized Azure estates are priced as a monthly fee based on scope, with the Azure consumption bill paid separately to Microsoft or through your CSP. Providers use four models: a fixed monthly tier (budget certainty, but you may pay for headroom), per resource or per VM (scales with the estate, but small resources can be priced like big ones), a percentage of Azure spend (simple, but the fee rises with spend unless savings are shared) and a base fee plus usage (predictable core, but needs careful contract review). Opsio uses fixed monthly tiers — see the price bands above.

The price is driven by the number of subscriptions, resources and environments in scope; coverage hours (24/7 for everything, or 24/7 for P1 only); security scope, from posture reviews to a full SOC on Microsoft Sentinel; hybrid servers through Azure Arc and ExpressRoute; and compliance reporting for NIS2, ISO 27001, SOC 2 or DPDP Act audits. Ask every provider about onboarding fees, tooling that adds Azure consumption (Log Analytics and Sentinel ingestion), premiums for out-of-hours changes, licence margins and exit costs.

When you compare an MSP fee with an in-house team, compare it with the cost of covering the same scope, not with one engineer's salary. A week has 168 hours, so keeping one person on duty around the clock takes more than four full-time positions before holidays, sick leave and training — and Azure operations span networking, identity, AKS, databases, security tooling and FinOps. Many organisations keep architecture and application ownership internal and hand 24/7 operations, patching, security monitoring and cost reviews to a provider, with a written responsibility matrix between the two.

Two service levels apply to every Azure workload. Microsoft's service level agreements cover the availability of each Azure service, and they often depend on your architecture, for example on using availability zones. Your MSP's SLA covers how fast the provider responds to and works on the issues it is responsible for. You need both in writing.

Availability figures translate into allowed downtime: 99.9% allows about 8.8 hours a year, 99.99% about 53 minutes. Opsio's uptime SLA and response times per priority are in the table above and are the same on every tier. Whoever you choose, ask how priorities are set, what counts as resolved and what happens when a target is missed, and agree secondary measures: backup success rate, patch compliance, restore-test results and the number of changes that caused incidents.

With least privilege, time limits and an audit trail. A partner with broad standing access is part of your attack surface, so this is the most useful technical question to ask. For Microsoft 365 and Entra ID, granular delegated admin privileges (GDAP) give partners time-bound, least-privilege access; ask which roles a provider requests and for how long. For Azure, Azure Lighthouse delegates specific subscriptions or resource groups to the provider while you keep control of who has access and can revoke it. Opsio operates your Azure estate through Azure Lighthouse delegation, so you can see and revoke our access at any time.

Red flags: shared admin accounts, engineers without MFA, standing Global Administrator roles, or a provider that cannot export a list of who accessed your tenant last month.

Microsoft is retiring the Azure Expert MSP programme: it stopped accepting new enrolments on 15 September 2026 and renewals end in January 2027 (Microsoft Partner Center). A provider that still holds the badge passed Microsoft's audit in the past, which is useful history, but it says little about how the provider runs 24/7 operations today.

Ask instead about current Solutions Partner designations and specialisations, verify them in Microsoft's partner directory, and then test the operating model directly. Opsio is a Microsoft Partner in the Microsoft AI Cloud Partner Program; the Verify us section above shows what you can check.
