A Managed Services Provider (MSP) delivers ongoing IT services — help desk, endpoint management, cloud, and basic security — for a monthly fee. A Managed Security Services Provider (MSSP) focuses specifically on cybersecurity — 24/7 threat monitoring, incident response, security operations, and compliance. For most small and mid-sized businesses in 2026, you need both capabilities, either from a single provider that offers both or from a coordinated pair of specialists.
What each provider actually delivers
Managed Services Provider (MSP)
An MSP handles day-to-day IT operations: help desk, endpoint management, patch management, cloud administration, backup, vendor management, and strategic planning. Modern MSPs include cybersecurity in the base offering — MFA, EDR on endpoints, email security, and awareness training. The scope is broad; the depth of any single capability is variable.
Managed Security Services Provider (MSSP)
An MSSP focuses exclusively on cybersecurity. Core services include a 24/7 Security Operations Center (SOC), advanced threat detection with SIEM/XDR, incident response, security engineering, penetration testing, and compliance framework support. MSSPs typically do not provide help desk, cloud administration, or general IT support.

| Factor | MSP | MSSP |
|---|---|---|
| Primary focus | IT operations + basic security | Advanced cybersecurity |
| Help desk | Yes | No |
| Endpoint management | Yes | Security-focused only |
| Patch management | Yes | For security patches |
| Cloud administration | Yes | No (except security) |
| Backup | Yes | Sometimes |
| 24/7 SOC | Sometimes | Always |
| SIEM / XDR | Sometimes | Always |
| Threat hunting | Rare | Standard |
| Incident response | Basic | Advanced |
| Penetration testing | No | Yes |
| Compliance depth | Moderate | Deep |
| Strategic IT planning | Yes | Security-focused only |
| Typical cost per user/month | $100-$250 | $50-$200 |
When you need an MSP
You need an MSP when:
- Your business needs day-to-day IT support (help desk, hardware, cloud, email)
- You have less than 50 employees and want a single point of contact
- Your cybersecurity needs are covered by a mature MSP's bundled security
- You want strategic IT planning integrated with operations
For most small businesses under 50 employees, a full-stack MSP is sufficient for both IT operations and cybersecurity. The MSP handles day-to-day work; a portion of your monthly fee funds the cybersecurity layer.
When you need an MSSP
You need an MSSP when:
- You are in a highly regulated industry (financial services under FTC Safeguards, healthcare under HIPAA, defense under CMMC)
- You have already suffered a breach and need advanced monitoring going forward
- Your cyber insurance carrier requires specific SOC or MSSP capabilities
- Your risk profile requires deeper capabilities than a bundled MSP security layer provides
- Your customers require attestation of specific security operations capabilities
MSSP engagements are typically layered on top of an MSP or internal IT team — the MSSP does not replace day-to-day IT support.
When you need both
Businesses in mid-market (50-500 employees) or in high-regulation verticals typically benefit from combining both:
- MSP for help desk, IT operations, cloud administration, endpoint management, and baseline security.
- MSSP for 24/7 SOC monitoring, advanced threat detection, incident response, and compliance-heavy security engineering.
The MSP and MSSP need to coordinate. The best structure names the MSP as the general contractor with the MSSP as a specialized subcontractor, so you have one point of accountability. PTG offers this coordinated model for clients that need both.
