MSP vs MSSP: What's the Difference and Which One You Need
What is the difference between an MSP and an MSSP?
An MSP (managed service provider) manages your day-to-day IT, including networks, devices, help desk, and uptime. An MSSP (managed security service provider) specializes in cybersecurity, running a security operations center (SOC) with tools like SIEM and EDR to detect and respond to threats around the clock. MSPs keep IT running; MSSPs keep it defended.
Do you need an MSP or an MSSP?
If your priority is reliable systems, help desk, and managed infrastructure, an MSP covers it. If you handle sensitive data, face compliance mandates, or need 24/7 threat monitoring, an MSSP is built for that. Many growing businesses need both, layering dedicated managed cybersecurity on top of general IT support.
Can one provider be both an MSP and an MSSP?
Yes. Many providers offer managed IT and managed security under one roof, and some MSPs add a SOC or partner with an MSSP to deliver security as a service. This combined model gives you a single accountable team for both uptime and protection, though it's worth confirming the security side has real SOC, SIEM, and incident-response capabilities, not just antivirus.
What is an MSP?
A managed service provider (MSP) is an outsourced IT department. They handle the technology that keeps your business operating: managing servers and networks, supporting laptops and workstations, running a help desk, patching software, backing up data, and planning for growth. MSPs typically bill a predictable monthly fee per user or per device, which replaces the unpredictable cost of break-fix repairs.
The core promise of an MSP is uptime and productivity. When email goes down, a server needs patching, or a new employee needs onboarding, the MSP handles it. Most include basic security hygiene such as firewalls, antivirus, spam filtering, and patch management. That baseline matters, but it is not the same as a dedicated security operation.

What an MSP typically covers
- Help desk and end-user support
- Network, server, and cloud infrastructure management
- Software updates, patching, and asset management
- Data backup and disaster recovery
- IT strategy, procurement, and budgeting
What is an MSSP?
A managed security service provider (MSSP) focuses specifically on protecting your organization from cyber threats. Where an MSP keeps the lights on, an MSSP watches for the people trying to break in. The engine behind an MSSP is the security operations center (SOC), a team of analysts who monitor your environment continuously, investigate alerts, and respond to incidents.
MSSPs run specialized tooling that goes well beyond standard antivirus. A SIEM (security information and event management) platform aggregates and correlates logs from across your systems to surface suspicious patterns. EDR (endpoint detection and response) watches endpoints for malicious behavior and can isolate a compromised device. Together with threat intelligence and 24/7 human analysis, these tools let an MSSP catch and contain attacks that automated, set-and-forget defenses miss. Explore the range of cybersecurity services MSSPs commonly deliver.
What an MSSP typically covers
- 24/7 SOC monitoring and threat detection
- SIEM log management and correlation
- EDR/MDR for endpoint protection and response
- Vulnerability management and penetration testing
- Incident response and security compliance reporting
MSP vs MSSP: side-by-side comparison
| Factor | MSP | MSSP |
|---|---|---|
| Focus | IT operations and uptime | Cybersecurity and threat defense |
| Core services | Help desk, networks, backups, patching | SOC monitoring, SIEM, EDR, incident response |
| Monitoring | System health and performance | 24/7 security events and threats |
| Compliance role | Supports requirements (backups, access) | Drives compliance with controls and reporting |
| Typical team | IT technicians and engineers | Security analysts and incident responders |
| When you need it | You need reliable, managed IT | You need active defense or must meet a security mandate |
Where MSPs and MSSPs overlap
The line between the two has blurred. Most MSPs now include security basics, and many MSSPs offer some IT management. Both monitor systems, both touch your infrastructure, and both bill on a recurring model. The key difference is depth: an MSP's security is usually preventive hygiene, while an MSSP's security is active detection and response backed by a staffed SOC. A firewall and antivirus reduce risk; a SOC analyst investigating an alert at 2 a.m. is what stops a breach in progress.
How to decide which you need
Start with your risk profile and obligations. Ask three questions: What data do we hold? What would an outage or breach cost us? Are we bound by any compliance framework? If you store regulated data such as health records or handle payment information, the security bar is higher and an MSSP-grade capability becomes essential. If you mainly need dependable systems and responsive support, a strong MSP may be enough on its own.
- Inventory your obligations. Map any compliance frameworks (HIPAA, PCI DSS, CMMC) to required controls.
- Assess your current coverage. Do you have real-time threat monitoring, or just antivirus?
- Weigh the cost of downtime versus a breach. Heavier breach exposure justifies dedicated security.
- Match the provider to the gap. Choose an MSP, an MSSP, or a combined team accordingly.

The co-managed and combined model
You don't have to pick just one. In a co-managed arrangement, your existing MSP keeps handling IT while an MSSP layers in dedicated security, or your MSP brings in SOC-as-a-service to fill the gap. This split lets each team do what it does best: the MSP owns uptime and user support, the MSSP owns detection and response. For organizations under a specific mandate, this layered approach is often the cleanest path, especially when paired with framework-specific expertise like HIPAA-compliant IT services. The goal is full coverage with clear accountability, so nothing falls between IT and security.
Frequently Asked Questions
How much more does an MSSP cost than an MSP?
An MSSP generally costs more than a comparable MSP engagement because you're paying for specialized analysts, a staffed SOC, and security tooling like SIEM and EDR rather than general IT support. Pricing varies widely by environment size, data sensitivity, and whether monitoring is 24/7. Many businesses control cost by keeping an MSP for IT and adding targeted MSSP services only for the security gaps they actually have, rather than buying a full security suite they won't use.
What exactly is a SOC?
A SOC, or security operations center, is the team and facility that monitors an organization's security around the clock. SOC analysts watch alerts from tools like SIEM and EDR, investigate suspicious activity, and coordinate incident response when something is wrong. It's the human layer that turns raw security data into action. MSSPs operate SOCs so clients get enterprise-grade detection and response without hiring and staffing an in-house security team, which is expensive and hard to keep covered overnight.
Can an MSSP work alongside my existing MSP?
Yes, and it's a common setup. In a co-managed model, your MSP continues handling IT operations, help desk, and infrastructure while the MSSP layers in security monitoring and response. The two coordinate on shared systems, with the MSP owning uptime and the MSSP owning threat defense. The main thing to nail down is clear ownership, so both teams know who handles what during an incident and there are no gaps between IT support and security operations.
Do compliance requirements force me toward an MSSP?
Often, yes. Frameworks like HIPAA, PCI DSS, and CMMC require specific security controls, continuous monitoring, logging, and documented incident response that exceed what a typical MSP provides. An MSSP is built to implement and report on those controls. If you're a defense contractor, for example, requirements like CMMC are demanding enough that dedicated security expertise is usually necessary. See our guide to CMMC compliance for defense contractors for specifics.
Should I build an in-house security team instead of outsourcing?
It depends on scale and risk. Building an in-house SOC means hiring security analysts, buying SIEM and EDR tooling, and staffing 24/7 coverage, which is costly and hard for small and mid-sized businesses to sustain. Outsourcing to an MSSP gives you mature processes, established tooling, and round-the-clock analysts immediately, usually at lower total cost. Large enterprises with deep budgets sometimes run hybrid models, keeping a small internal team while outsourcing overnight monitoring and surge response to an MSSP.
