What Is a Managed Service Provider (MSP)? How MSPs Work

A managed service provider (MSP) is an outside company that runs part of your IT for you on an ongoing contract. It monitors, patches, backs up, secures and fixes the systems in scope, usually around the clock, against agreed service levels. You pay a recurring fee; the MSP carries the day-to-day operational work.

Key takeaways

• An MSP is paid to keep systems running and improving, not to fix things only after they break.
• EU law now defines MSPs: the NIS2 Directive covers "installation, management, operation or maintenance" of ICT, on-site or remote.
• A cloud provider such as AWS or Azure owns the platform; an MSP operates your workloads on it. Most cloud customers need both.
• Pricing is per device, per user, tiered, a share of cloud spend or fixed fee. Each model creates different incentives.
• You can hand an MSP the tasks, but not your regulatory accountability. Write the split of duties into the contract.
• Azure Expert MSP is being retired by the end of 2027, so check which current Microsoft or AWS validation a provider actually holds.

What does an MSP do?

An MSP takes operational ownership of an agreed slice of your environment. That slice might be your AWS accounts, your Microsoft 365 tenant, your network, your laptops or your security monitoring.

Typical recurring work includes:

• 24/7 monitoring and alerting on servers, databases, networks and cloud services
• Incident response and fixes within agreed response and resolution times
• Patching operating systems and keeping configurations consistent
• Backups, plus regular tests that restores actually work
• Security monitoring, vulnerability management and access reviews
• Cloud cost reviews: rightsizing, scheduling and commitment discounts
• Monthly reporting on availability, incidents and spend, plus planned improvement work

The EU now has a legal definition. The NIS2 Directive, Article 6(39), defines an MSP as an entity that provides "services related to the installation, management, operation or maintenance of ICT products, networks, infrastructure, applications or any other network and information systems, via assistance or active administration carried out either on customers' premises or remotely". Annex I of the same directive lists MSPs and managed security service providers as a covered sector.

How an MSP works in practice

A working MSP service rests on three layers. If one is missing, you are buying a dashboard with a phone number.

Tooling

The MSP installs monitoring agents and log collection, and manages infrastructure as code (Terraform or CloudFormation). It uses observability tools (CloudWatch, Azure Monitor, Datadog) and a ticketing system. Good providers keep this code in your repositories, not theirs.

Process

Runbooks describe how each type of alert is handled, from a disk filling up to a suspected breach. Change management, capacity reviews and post-incident reviews sit on top. Ask to see real, redacted examples.

People

Engineers in a network operations centre (NOC) and security operations centre (SOC) carry out the runbooks. Their real value is pattern recognition. A team that has seen the same failure in many environments fixes it faster than one seeing it for the first time.

Types of managed service providers

MSPs differ by what they run and which platforms they know. Match the type to your estate before you start comparing names.

The line between cloud MSP and MSSP is blurring. You cannot run a cloud estate responsibly without security monitoring built in, so many providers sell both under one contract. Our comparison of MSP vs MSSP vs MDR goes deeper.

MSP vs cloud provider vs IT services firm

These are the three roles buyers mix up most. The difference is ownership and accountability.

Responsibility for security is split in layers. AWS describes its shared responsibility model as security "of" the cloud (AWS) versus security "in" the cloud (the customer). With an MSP there are three layers:

• Cloud provider: physical data centres, hardware, the hypervisor and managed service availability.
• MSP: what the contract says, such as OS patching, monitoring, incident response, backup tests and cost governance.
• You: application code, data classification, access decisions and regulatory accountability.

Gaps appear at the edges. Who patches container base images? Who approves IAM changes? Put the answers in a RACI matrix attached to the contract.

What is an Azure or AWS managed service provider?

It is an MSP that specialises in one cloud and has passed that cloud vendor's validation. Both programmes use outside auditors, so the badges carry more weight than a reseller listing.

• AWS. The AWS MSP Partner Program requires partners to "complete a rigorous third-party audit that assesses your technical skills and business health". You can check a partner in AWS Partner Solutions Finder.
• Azure. Microsoft's Azure Expert MSP involves a pre-audit assessment and a two-day audit by a third party. Microsoft has announced that Azure Expert MSP "will retire by the end of 2027" and points partners to its Frontier Partner specialization. If a provider leads with the Expert MSP badge, ask what it is moving to.

Single-cloud specialists go deeper; multi-cloud MSPs cover more ground. If you run 95% on AWS with one leftover Azure subscription, you need an AWS specialist who can watch the Azure part. If an acquisition left you with two real platforms, check that the MSP has certified engineers on both. A slide deck is not enough. See our pages on AWS managed services and Azure managed services for what each covers.

How many companies use an MSP?

Most organisations using public cloud get outside help with it. Flexera's 2025 State of the Cloud Report found that 60% of organisations used MSPs in some capacity to manage public cloud. Its 2026 report found enterprise MSP use up 3 percentage points, while SMB use fell from 48% to 39%, which Flexera links to budget pressure.

What Are the Benefits of using an MSP?

• Skills you could not hire one by one. Cloud networking, Kubernetes, FinOps and security analysis are separate specialisms. An MSP spreads those people across many customers.
• Real 24/7 cover. Staffing a round-the-clock rota yourself means several people per role once you count holidays, sickness and turnover.
• Faster incident handling. Cross-customer experience shortens diagnosis.
• Cost discipline. Someone owns the cloud bill every month: rightsizing, removing idle resources, and sizing and renewing commitment discounts such as Savings Plans.
• Compliance support. Under NIS2 Article 21, covered organisations must manage supply chain security, including relationships with their service providers. An MSP with ISO 27001 certification and a clear GDPR data processing agreement makes that evidence easier to produce.

Risks and trade-offs

Any honest guide has to cover what goes wrong. These are the usual failure points and how to limit them.

• Lost internal knowledge. After a few years your team's hands-on skills fade. Fix: keep documentation, IaC and runbooks in your own systems and schedule knowledge-transfer sessions.
• SLA gaming. An alert acknowledged in 30 seconds and triaged 45 minutes later still "meets" a response SLA. Fix: measure time to resolution and time to a useful update, and ask for MTTR distributions, not averages.
• Lock-in to the MSP. Proprietary tooling and harsh exit clauses make leaving hard. Fix: prefer open or cloud-native tooling and agree transition support up front.
• Misaligned cost incentives. A fee based on a share of cloud spend rewards a bigger bill. A fixed fee rewards less effort. Fix: add shared-savings terms or quarterly cost reviews.
• Cross-border data rules. If the SOC sits outside the EU and your data is in EU regions, GDPR transfer rules apply. Fix: check the safeguards (such as standard contractual clauses) in the contract, then audit them.

MSP pricing models compared

Prices vary too much by scope to quote a fair average. Compare the model first, then the number.

Always compare the MSP fee plus the cloud bill against the fully loaded cost of doing the same work in-house.

How to choose an MSP

1. Define the scope first. List which workloads and environments are in scope, which tasks move and which compliance frameworks apply.
2. Check validations, then look past them. AWS MSP, Microsoft designations and ISO 27001 are the entry ticket. Ask for a redacted post-incident review; it shows more than any badge.
3. Run a tabletop test. Give a scenario such as "Friday 23:00 CET, CloudTrail shows a root console login from an unknown IP" and ask for each step from detection to fix.
4. Read the SLA clock. Check 24/7 versus office hours, severity definitions, service credits and exclusions.
5. Agree the exit. Cover data and configuration export, a transition period, access for a successor, and ownership of the automation built for you.

When an MSP is the wrong choice

• Infrastructure is your product. If latency or custom hardware is your edge, you need your own engineers.
• You have the scale. At very high cloud spend, an in-house platform team can cost less than the MSP fee and keeps the knowledge in-house.
• Rules forbid third-party access. Some defence and classified workloads cannot be run by an outside operator.
• Nobody knows your stack. For niche HPC or custom hardware, the MSP talent pool may be too small.

Example: 24/7 managed operations on AWS

Opus Bilprovning is one of Sweden's largest vehicle inspection companies, with nearly 100 stations and around two million inspections a year. It wanted one accountable partner for its whole AWS estate across CloudOps, DevOps and SecOps. Opsio now runs that estate with 24/7 operational support, proactive monitoring, change management and continuous security hardening. The internal team stays focused on inspections. Read the Opus Bilprovning case study.

Frequently asked questions

What is an example of an MSP?

A cloud MSP that runs 24/7 monitoring, patching, incident response and cost control across a company's AWS and Azure accounts for a monthly fee is a typical example. Opsio, the publisher of this article, is one; see our managed services overview. Large IT services firms and many regional IT support companies also sell managed services.

What is the difference between an MSP and a cloud provider?

A cloud provider such as AWS, Azure or Google Cloud owns and runs the platform. An MSP operates your workloads on that platform: monitoring, patching, security and cost. The platform bill goes to the cloud provider; the operations fee goes to the MSP.

Is an MSP the same as an IT service provider?

An MSP is one kind of IT service provider. IT services firms may sell projects, consulting or break-fix support. An MSP specifically takes ongoing responsibility for running systems under an SLA.

How much does an MSP cost?

It depends on scope, estate size and SLA level, so published averages are a poor guide. Common models are per device, per user, tiered bundles, a share of cloud spend and fixed fees with shared savings. Ask for a quote based on your inventory and compare it with the full cost of in-house staff.

Are MSPs covered by NIS2?

Yes. NIS2 lists managed service providers and managed security service providers in Annex I, so in-scope MSPs have their own security duties. Their customers must also manage supply chain security under Article 21.
