MSP vs MSSP

An MSP (managed service provider) runs your day-to-day IT: devices, networks, help desk and patching. An MSSP (managed security service provider) focuses on monitoring and defending against threats, often 24/7. Many companies buy outsourced IT services from both, and multi-location firms add onsite IT support services for the physical work neither provides; Techmate covers that in 450+ US cities.

Service providers can streamline your business operations and free up your employees for other projects. Many organizations enlist third-party providers, but the primary reason for hiring one can vary. Both MSPs and MSSPs can strengthen your current setup and give you access to expertise you would struggle to hire. Which model fits depends on what you need to achieve, how regulated your industry is, and how many locations you support.

This guide breaks down what each provider does, how their tools and skills differ, the pros and cons of each, how they compare to MDR and SOC services, and who handles the hands-on work at your offices when both are remote.

What is the difference between an MSP and an MSSP?

An MSP manages your IT environment so it runs reliably. An MSSP protects that environment from threats. There is real overlap, since most MSPs include basic security and some MSSPs manage firewalls and endpoints, but the center of gravity is different.

Factor	MSP	MSSP
Primary goal	Keep IT running efficiently	Detect, prevent, and respond to security threats
Typical services	Help desk, device and network management, patching, backups	Security monitoring, SIEM, managed firewall, vulnerability scanning, incident response
Core tools	RMM, PSA ticketing, backup platforms	SIEM, IDS/IPS, EDR, threat intelligence feeds
Operating hours	Business hours, with after-hours options	Usually 24/7/365 monitoring
How you engage them	When something breaks or needs changing	Continuously, plus incident response when an alert fires
Staff skills	Systems, networking, end-user support	Security analysis, forensics, threat hunting
Onsite work	Usually remote, limited local presence	Almost entirely remote

What does an MSP do?

An MSP is a third-party company that remotely manages a client’s IT and end-user systems. Its job is to make IT operations more dependable and predictable. Common MSP services include:

Infrastructure and network management
Remote monitoring of servers, devices, and connectivity
Help desk support for employees
Patch management for operating systems and software
Backup and disaster recovery
Baseline security such as antivirus, antimalware, and basic firewall management
Vendor management for internet, phones, and software

Businesses usually call their MSP when something happens or needs to change. For a deeper look at the model, see our definition of an MSP.

What does an MSSP do?

An MSSP provides outsourced management and monitoring of a business’s security systems. Instead of waiting for a ticket, it watches for threats continuously. MSSP services typically include:

Endpoint protection and antivirus management
Incident response planning and services
Intrusion detection and prevention
Managed firewall
Security consulting
Security information and event management (SIEM)
Threat detection and prevention
Managed VPN and secure remote access
Vulnerability scanning

MSSPs often run their monitoring from a security operations center (SOC) staffed around the clock.

How do MSP and MSSP tools, skills, and compliance differ?

Tools and technology

Because their scope differs, the two use different toolsets. MSPs rely on general IT management tools such as RMM (remote monitoring and management) software and ticketing systems. MSSPs use specialized security tools like IDS (intrusion detection systems), EDR (endpoint detection and response), and SIEM platforms that collect and correlate logs from across your environment.

Skill sets and expertise

An MSP gives you access to infrastructure generalists who cover a wide range of IT services. An MSSP gives you dedicated security specialists skilled in areas like incident response, threat hunting, and data loss prevention. Those specialists are hard to hire: 59% of organizations reported critical or significant cybersecurity skills shortages in ISC2’s 2025 workforce study, up from 44% the year before (Infosecurity Magazine reporting ISC2, 2025). That shortage is one of the strongest arguments for an MSSP.

Compliance and regulatory requirements

Both types of provider must handle your data responsibly, but MSSPs usually work under more security-specific obligations and produce more evidence for audits. Depending on your industry, either may need to support frameworks such as HIPAA for healthcare, GLBA and examiner guidance for financial institutions, PCI DSS for card payments, or FISMA for federal work. Ask each provider which frameworks they support today, and what documentation they will hand you at audit time.

What are the pros and cons of using an MSP?

MSPs are effective in some environments and less so in others.

Advantage: process and system management. MSPs standardize how devices, accounts, and networks are managed.
Advantage: predictable cost. Most charge a monthly fee per user or device.
Advantage: continuity. Backups and documented recovery steps help you react to outages and adverse events.
Drawback: limited onsite presence. MSPs work mostly remotely, which hurts when a switch fails or a laptop dies at an office far from their base.
Drawback: security depth varies. Basic antivirus and patching is not the same as 24/7 threat monitoring.
Drawback: coverage gaps. Finding one MSP that covers every aspect of IT, at every location, can be difficult.

What are the pros and cons of using an MSSP?

Many companies will do what it takes to protect their IT environment, and MSSPs can help. They’re not always the ideal choice, however.

Advantage: a security team without building one. You get analysts and tooling that would take years and significant budget to assemble in-house.
Advantage: current expertise. MSSP analysts see threats across many clients and keep up with new attack patterns.
Advantage: around-the-clock monitoring. Most MSSP services run 24/7/365.
Drawback: added cost. An MSSP adds to, rather than replaces, the cost of running IT.
Drawback: you still need an internal owner. Someone in-house must act on findings, approve changes, and coordinate with your MSP.
Drawback: trust. Some companies are uncomfortable giving a third party visibility into their most sensitive systems.

The stakes explain why companies accept those costs. IBM’s 2025 Cost of a Data Breach report put the average US breach at $10.22 million, an all-time high, against a global average of $4.44 million (CyberScoop reporting IBM, 2025).

How do MSP, MSSP, MDR, and SOC compare?

These terms get mixed together in proposals. Here is how they relate:

Term	What it is	Best fit
MSP	A provider that manages IT infrastructure and end-user support	Companies that need reliable day-to-day IT
MSSP	A provider that manages and monitors security systems	Companies that need ongoing security operations and compliance evidence
MDR	Managed detection and response: a service focused on finding, isolating, and responding to active threats	Companies that already have security tools but need people to act on alerts
SOC	A security operations center, the team and facility that monitors security events	Delivered in-house by large enterprises, or as part of an MSSP or MDR service

Which do you need: an MSP, an MSSP, or both?

Start with the most critical gap before you buy outsourced IT services. Consider the scope of your needs, the expertise required, your budget, and your regulatory exposure.

Choose an MSP if your main problem is everyday IT reliability: help desk, devices, networks, and vendors. Many MSPs include baseline security, but they are not dedicated threat hunters.
Choose an MSSP if your primary need is threat monitoring, incident response, or security evidence for audits, and you already have IT operations under control (in-house or through an MSP).
Use both if you are growing, handle sensitive data, or face regular audits. The MSP keeps systems running; the MSSP watches them.

By company profile:

Small businesses usually start with an MSP and add an MSSP or MDR service as they scale or win clients that require security reviews.
Mid-sized businesses are often fine with an MSP, depending on data sensitivity and client requirements.
Organizations in high-risk sectors such as finance or healthcare typically rank security as a top concern and should engage an MSSP alongside their IT operations provider.
Law firms handling confidential client matters increasingly face security questionnaires from clients, which pushes them toward MSSP or MDR coverage.

How do outsourced IT services cover onsite work at branch offices?

Here is the gap most MSP versus MSSP comparisons skip: neither provider usually has people near every one of your locations. An MSSP may detect a compromised device at a branch, and your MSP may confirm a failed firewall, but someone still has to go to the site, swap the hardware, re-patch the network closet, or collect a laptop for investigation.

Distributed companies handle this in a few ways:

Local staff at large sites, which rarely scales to small branches
Local IT shops at each location, which creates a patchwork of vendors and standards
A nationwide field services partner that dispatches vetted technicians to any site on request from your MSP, MSSP, or internal team

The third option keeps your outsourced IT services provider focused on remote management while physical tasks, from onsite IT network services in network closets and IDFs to device swaps, get done locally. Our posts on how MSPs use field technicians and why traditional MSPs struggle with distributed enterprises go deeper. If you are weighing a managed agreement against dispatch, see on-demand vs managed IT.

Techmate is not an MSP or an MSSP. It is the onsite layer: 7,000+ vetted technicians across 450+ US cities, with a 97% resolution rate, working alongside whichever remote providers you choose.

How do you transition between MSP and MSSP providers?

As your company grows, adding an MSSP or replacing your MSP often makes sense. Third-party access is a major risk area: Verizon found third-party involvement in breaches doubled to 30% (Verizon DBIR, 2025). Plan the handover carefully:

Check your agreement end date. Some providers impose cancellation fees if you stop service outside the terms of the agreement.
Audit active hardware. A new provider needs to know what they will support, and the audit is a valuable cross-check on what you are paying for.
Ask for a runbook (with credentials) from your current provider. This data and access belong to you, not the provider.
Gather software licensing. Know what you own, which helps with renewals and upgrades.
Rotate credentials and remove old access the day the outgoing provider’s work ends.
Define who does what when you run an MSP and an MSSP side by side, so alerts never fall between them.

Many MSPs now market security services, and some have genuinely built MSSP capabilities. Ask what is delivered by their own analysts, what is outsourced to a partner, and what hours the monitoring actually runs.

What should you ask an MSP or MSSP before signing?

What exactly is included, and what is billed separately?
Who monitors our environment overnight and on weekends?
What happens, step by step, when you detect an incident at one of our branch offices?
Who performs onsite work at each of our locations?
Which compliance frameworks do you support, and what evidence do we receive?
Will you use named accounts, and how is your access removed if we part ways?
How do you work with our other providers?

Frequently Asked Questions

What is the difference between an MSP and an MSSP?

An MSP’s primary focus is managing IT infrastructure and end-user support, while an MSSP’s goal is to monitor and protect your security systems. Both are managed service providers, but one keeps IT running and the other defends it. Many companies use both, with clear rules about which provider handles each type of alert or request.

What is the difference between an MSP and a SOC?

An MSP is a provider that works with organizations to manage IT networks, devices, and support. A SOC, or security operations center, is the team and facility that monitors security events and responds to threats. Large enterprises may run their own SOC; smaller organizations usually access one through an MSSP or MDR provider.

What is the difference between an MSSP and MDR?

MSSPs manage and monitor a broad set of security systems, such as firewalls, SIEM, and vulnerability scanning. MDR, or managed detection and response, is narrower and more hands-on: it focuses on detecting, isolating, and responding to active threats on your endpoints and network. Some MSSPs include MDR, and some MDR providers sell it as a standalone service.

Why do MSPs offer cybersecurity services?

MSPs can address network weaknesses before they become problems, and more businesses now must safeguard sensitive data for clients, insurers, and regulators. Basic protections such as patching, antivirus, and backups fit naturally into managed IT. Ask whether an MSP’s security offering includes continuous monitoring or only preventive maintenance, because that difference matters during an incident.

What types of businesses benefit from MSP and MSSP services?

Any business, regardless of size, can benefit. Small and mid-sized companies often start with an MSP for general IT maintenance. Larger organizations, regulated industries such as finance and healthcare, and companies that handle sensitive client data should consider adding an MSSP. Multi-location companies of every size also need a plan for onsite work at each site.

Do MSPs or MSSPs provide onsite support at branch offices?

Sometimes, but usually only near their own offices. Most MSP and MSSP work is delivered remotely. For companies with locations across the country, a nationwide field services partner can dispatch technicians to handle hardware swaps, network closet work, and device collection on behalf of your MSP, MSSP, or internal IT team.
