What is the difference between an MSP and an MSSP?

An MSP (Managed Service Provider) handles all IT management — help desk, monitoring, patches, Microsoft 365, and security as a component. An MSSP (Managed Security Service Provider) focuses exclusively on cybersecurity with a 24/7 SOC, SIEM, MDR, threat hunting, and compliance reporting — but does not handle day-to-day IT support.

When does a Canadian business need an MSSP?

Consider MSSP services when you need dedicated 24/7 SOC capabilities beyond what a typical MSP provides, have compliance requirements mandating a formal SOC (OSFI B-13, SOC 2), have an existing in-house IT team that needs security augmentation, or have experienced a significant breach requiring stronger detection.

Can an MSP provide MSSP-level security?

Some MSPs offer MSSP-grade security by partnering with MDR providers and SIEM vendors. The key question is whether the MSP has dedicated security analysts monitoring your environment 24/7. Outsource IT Canada operates The Cyber Arm Security as a dedicated security division providing MSSP-level services.

What Is an MSSP (Managed Security Service Provider)?

An MSSP — Managed Security Service Provider — is a specialized type of IT service provider focused exclusively on cybersecurity, operating a 24/7 Security Operations Centre (SOC) staffed by security analysts who monitor your environment, hunt for threats, and respond to incidents. Unlike an MSP that provides broad IT management, an MSSP focuses entirely on security — SIEM, MDR, vulnerability management, threat intelligence, and compliance reporting.

MSP vs. MSSP: key differences

MSP scope: full IT management — monitoring, help desk, patches, Microsoft 365, backups, networking, and security as a component
MSSP scope: security only — SOC monitoring, SIEM management, MDR, vulnerability management, pen testing, compliance reporting
Day-to-day IT: MSP handles all IT issues; MSSP does not provide IT helpdesk, device provisioning, or end-user support
Security depth: MSSP provides deeper security expertise with dedicated security analysts, threat hunters, and incident responders; MSP security is typically delivered using security tools and partner MDR services
Cost: MSSPs typically cost more per endpoint than adding security to an MSP engagement; appropriate when security expertise must be dedicated rather than shared

When does a Canadian business need MSSP vs. MSP?

Choose an MSP with strong security tools if:

You need both IT support and security for a single contract
Your business is under 100 users
Your compliance requirements (PIPEDA, PHIPA) can be met with EDR + MFA + email security + tested backups
Budget is a primary consideration

Consider adding MSSP services if:

You have an existing IT team and need to add dedicated 24/7 SOC capabilities
Your compliance framework requires a formal SOC (OSFI B-13, SOC 2, ISO 27001)
You've experienced a significant breach and need stronger detection and response
You are in a regulated industry where cyber incidents carry regulatory reporting obligations
