MSP vs MSSP: What Is the Difference?
MSP or MSSP? For most small businesses, you need both.
A managed service provider keeps your technology running. A managed security service provider focuses on defending it. Here is how they differ and how to get both without paying twice.
MSP vs MSSP, answered directly
By Joe Engelking, CEO. Updated October 2026.
What is an MSP?
A managed service provider runs your day-to-day IT for a monthly fee. It handles the help desk, monitoring, updates, backups, user accounts, and vendor coordination, so your systems keep working. Its main job is keeping technology available and supported.
What is an MSSP?
A managed security service provider focuses on protecting your systems. It monitors for threats around the clock, manages security tools such as firewalls and endpoint protection, investigates alerts, and responds to incidents. Its main job is detecting and stopping attacks.
What is the difference between an MSP and an MSSP?
An MSP keeps IT running, and an MSSP defends it. Their work overlaps, since patching and backups matter to both. Some providers do only one. Many small businesses are best served by a single provider that does both, so security and operations are coordinated instead of separate.
Does a small business need both?
Usually yes, but not from two companies. The risk is that IT and security are handled by different teams who each assume the other has it covered. A provider that combines both gives you one accountable team, one relationship, and security built into daily operations.

| Accountability | For uptime | For threats | One team for both |
More questions about MSPs and MSSPs
Costs vary with the size of your environment and the level of monitoring. Security-only providers add to your IT spend, while a combined provider usually prices both together in one flat plan. We quote after a short call and deliver the quote the same day.
Managed detection and response is a specific service where analysts monitor, investigate, and respond to threats. An MSSP may offer MDR along with broader security management, such as firewalls, email security, and compliance reporting. Ask any provider exactly what they will respond to and how fast.
Many do. Security monitoring, logging, and documentation support frameworks like HIPAA, SOC 2, and ISO, and help answer insurer and customer questionnaires. Compliance still requires policies and processes on your side, which a good provider helps you build.
A security operations center is a team that watches security alerts and responds. Small businesses usually do not build their own. They get that coverage through a provider that has a SOC, which is much more affordable than staffing one internally.
Ask who will answer when something goes wrong, whether monitoring is watched by people or only software, how backups are tested, what is included in the price, and whether they will help with insurance and customer questionnaires. References from similar businesses help.
Yes, some do. That can work if the two teams coordinate well. The risk is delays and finger-pointing when something happens. Ask who owns the response and how the handoff works before you rely on that arrangement.
Choosing between an MSP, an MSSP, and MDR
| Topic | MSP | MSSP | MDR |
|---|---|---|---|
| Main job | Run day-to-day IT: help desk, patching, backups, Microsoft 365 | Watch for and respond to security threats around the clock | Detect threats on devices and accounts and act to contain them |
| Typical deliverables | Support tickets, updates, monitoring, vendor management | Security monitoring, alert review, incident response, compliance reporting | Endpoint monitoring and response by analysts, not just alerts |
| Best fit | Businesses that need reliable everyday IT | Businesses with compliance, insurance, or customer security demands | Businesses that want more than antivirus but do not run their own security team |
| LME offers it? | Yes | Yes, as part of our managed security | Yes |
- MSP only if you mainly need help desk, patching, backups, and Microsoft 365, and no one is asking you to prove your security.
- MSSP or managed security if you face HIPAA, SOC 2, cyber insurance, or customer security questionnaires, or if you have been breached before.
- Both for most small and mid-size businesses. The simplest answer is one provider that does both, so the team fixing a problem is the team watching for threats. That is how LME works.
