What Is an MSP? A Guide to Managed Services

Short answer: MSP stands for managed service provider: a company that takes over the operation of an organization's technology infrastructure or systems under contract. The provider monitors the systems continuously, maintains them and responds to failures; what gets done and how fast is written into the service level agreement (SLA). The model itself is called managed services. What transfers is the operation; accountability to the regulator stays with the organization.

What is an MSP?

MSP is short for managed service provider. The organization hands the day-to-day operation of a defined part of its infrastructure to the provider: servers, network, storage, cloud resources, backup, security operations or end-user support. The provider does this work with remote monitoring and management tools, a 24/7 operations center and defined processes; what stays with the organization is tracking the contract, the scope and the service level.

What sets an MSP apart from other technology vendors is that it sells continuity rather than a product or a project. The hardware vendor is done when the device is delivered and the integrator when the project ends; the MSP's work continues as long as the system runs, and the service is measured by outcomes: availability, response time, resolution time.

What are managed services?

Managed services are easiest to understand next to the alternative. In the classic model ("call us when it breaks"), someone is called in when a problem appears and the work is billed by the hour or per call. Nobody watches the systems when nothing is broken; nobody warns you that a disk is about to fill up or notices the server whose patches are overdue.

	Break-fix	Managed services
Relationship	Per incident	Continuous, under contract
Monitoring	None; users report problems	24/7; problems caught at the threshold
Fee	Per hour or per call	By scope, monthly
Provider's incentive	Earns when things break	Earns when they don't
Measurement	None	SLA, monthly report

With managed services, the relationship is continuous:

Proactive operations: Systems are monitored 24/7; a disk approaching its threshold, a certificate about to expire or a server behind on patches is dealt with before it turns into a failure.
Defined scope: Which systems, which tasks and which hours the service covers is written into the contract.
Measured service level: Targets for availability, response time and resolution time are set and reported every month.
Predictable cost: The fee depends on scope, not on the number of calls. The provider earns when failures don't happen, not when they do, so the incentive points the right way.

What does an MSP do?

The work a managed service provider takes on usually falls under these headings:

Infrastructure management: Day-to-day operation of physical and virtual servers, network devices and storage systems (infrastructure management).
Managed cloud: Monitoring, patching, backing up and tracking the cost of cloud resources (managed cloud services). We explain the difference in our IaaS article.
Backup and disaster recovery: Taking backups, testing that they restore and rehearsing the disaster scenario (backup and recovery).
Monitoring and incident response: 24/7 monitoring, first response to alerts and escalation (24/7 monitoring).
Security operations: Patch management, log monitoring and response to security incidents (security operations).
Database and platform operations: Running databases and enterprise platforms as a service (managed platform services).
End-user support: Help with employees' device and application problems (end-user support).

There is no need to buy all of this from one provider. Starting with a single layer (backup or monitoring, for example) and widening the scope as trust builds is also an option.

MSP, MSSP and cloud provider: the difference

Three terms get mixed up because all three are "providers":

An MSP takes over the operation of the infrastructure: monitoring, maintenance, patching, backup, response. Its scope may include security tasks, but its focus is keeping systems running.
An MSSP (managed security service provider) focuses on security alone: log collection and analysis, threat detection and response to security incidents, usually through a SOC. Some MSPs offer this layer too; some organizations buy the two from separate providers.
A cloud provider (IaaS) gives you the infrastructure and does not operate it. It provisions the virtual machine, but patching the operating system on it, backing it up and monitoring it are your job. This is exactly where an MSP comes in: in the cloud or in your own data center, it takes over the operation of the infrastructure. We draw the line of responsibility in our IaaS article.

Managed service models

Full handover: Operation of the defined area moves entirely to the provider; inside the organization, only a counterpart who tracks the contract and the service level remains.
Co-managed: Routine operations sit with the provider, while architecture decisions and work close to the business stay with the internal team. In the organizations we work with, this is the most common arrangement; the internal team does not disappear, it gets out of night shifts and repetitive work.
Layer-based: Only a specific layer is handed over: for example, only backup and disaster recovery, or only 24/7 monitoring and first response.

MSP pricing models

The price of a managed service is mostly set by scope, and the industry uses a few common models:

Per device or system: A fixed monthly fee for every managed server, virtual machine, network device or database. Predictable for organizations with a known inventory and a changing headcount.
Per user: For services centered on end-user support, a monthly fee per employee, independent of the number of devices.
Tiered or packaged: Service hours (business hours or 24/7), the target service level and the included tasks are grouped into packages; the organization picks the tier it needs.
Custom quote by scope: In large and mixed environments, a quote calculated from the inventory, service hours, SLA targets and included tasks.

Three things drive the price: the number and type of systems managed, the service hours and the target service level. That is why two offers for the same systems should be compared only after confirming that they cover the same scope; the cheaper-looking offer often leaves out night hours or incident response.

Why do organizations use managed services?

The first reason is how hard it is to find skilled people. In ISC2's 2025 Cybersecurity Workforce Study, 95% of respondents said their team has at least one skills need, and 59% reported critical or significant skills needs, up from 44% a year earlier. The picture on the infrastructure side is similar: in Uptime Institute's 2026 data center survey, more than half of operators said they struggle to find qualified candidates.

The second reason is the math of 24/7 operations. A year has 8,760 hours; after leave, public holidays and training, one person works roughly 1,800 hours a year. Keeping a single on-call seat filled all year therefore takes about five people, and that covers only the first response layer; we show the calculation in detail in our SIEM and SOC article. Building that headcount across several areas of expertise is not economical for most organizations.

The third reason is focus. Infrastructure running smoothly is critical for every organization, but for most it is not the core business. When routine operations move to a provider, the internal team can spend its time on projects that affect the business directly.

Starting with an MSP: how onboarding works

The service does not start on the day the contract is signed; there is an onboarding period in between, and its quality decides the quality of the years that follow. A good onboarding usually goes through these steps:

Discovery and inventory: Which systems exist, which are in scope, which applications depend on which servers. Undocumented systems are where onboarding most often stumbles.
Access and monitoring: The provider's monitoring and management tools are installed, access is set up, and alert thresholds are tuned to the organization's real load.
Runbooks: For every system, "what to do when it fails" is written down: the escalation chain, maintenance windows, backup and restore steps.
Parallel period: For a while the old arrangement and the new one run side by side; the provider starts monitoring while response still sits with the internal team. The service level is measured only after this period.

Onboarding takes anywhere from weeks to months depending on scope. Asking for the plan, the duration and the division of work in writing at the proposal stage prevents the "that was out of scope" argument later.

What to check in an SLA

The service level agreement is the heart of a managed services contract. When comparing offers, look at the answers to these questions before the price:

What does it measure? For which system is availability measured, and from which point? Are response time and resolution time defined separately?
Who measures it, and how is it reported? Do you have access to the measurement data too, and does the report put results next to targets every month?
Who is on call at night? Is the 24/7 rotation staffed by the provider's own team, or handed to a subcontractor?
What happens if you want to leave? Are the inventory, runbooks, access details and handover period written into the contract?

Choosing an MSP in Türkiye

Three questions stand out when choosing a provider in Türkiye: where data and backups are kept (for KVKK and sector regulation), whether the provider has its own data center and its own 24/7 team, and whether its certifications (such as ISO 27001) come with a contractual right to audit. You can find a detailed list of questions in our article on 10 questions to ask when choosing an MSP, and what companies in Türkiye actually look for in a provider in our MSP selection article.

Who is accountable in regulated organizations?

Handing over operations does not mean handing over obligations. For banks, BDDK regulation keeps responsibility with the bank when it buys cloud or outsourced services; in an outage or a breach, the regulator deals with the bank, not the provider (our BDDK article). For organizations covered by Cyber Security Law No. 7545, obligations such as incident reporting also stay with the organization itself (our Cyber Security Law article). That is why the contract should spell out the records, reports and notification times the organization needs to meet its own obligations.

We do this work as a managed service provider headquartered in Türkiye, and in 2026 we ranked first in the Türkiye-based Managed Services category of the Bilişim 500 survey. You can see the full scope on our managed services page.

Frequently asked questions

What does MSP mean? Managed service provider: a company that runs organizations' infrastructure and systems under contract.

What does managed services mean? Handing the operation of technology infrastructure and systems to a provider, with the scope and service level defined in a contract.

What is the difference between an MSP and an MSSP? An MSP takes over the operation of the infrastructure; an MSSP focuses only on security operations: log analysis, threat detection and response to security incidents. Some providers offer both.

Are managed services the same as outsourcing? Managed services are a kind of outsourcing, but narrower and measurable. Classic outsourcing models often supply staff or labor; with managed services you buy an outcome: a defined scope run at a measured service level.

Do managed services replace the internal team? Usually not. In the most common arrangement we see, routine operations and on-call duty move to the provider, and the internal team focuses on architecture decisions and projects close to the business. Full handover is possible too, but it should be a deliberate decision.

How is the fee for managed services set? Mostly by scope: the number and type of systems managed, service hours (business hours or 24/7), the target service level and the tasks included. Per-device, per-user and packaged models are common.

Do managed services make sense for a small company? Often that is where they make the most sense: building a full-time team for a few servers and a cloud account is not economical, but an unmonitored system fails the same way in a small company. The layer-based model lets a small organization buy only the work it needs.
