This guide on MSP vs MSSP is part of our ongoing series for vendors selling into the MSP channel.
“MSP” and “MSSP” get used almost interchangeably in a lot of vendor outreach, but treating them as the same buyer is a common way to get an otherwise-good pitch ignored — the two run genuinely different businesses with different priorities.
What an MSP actually does
A managed service provider (MSP) is responsible for the day-to-day health of a client’s IT environment — help desk, patching, backups, network monitoring, procurement. Security is usually one part of a broader service bundle, not the entire pitch. An MSP’s buying decisions are driven by ticket volume, technician efficiency, and client retention.
What an MSSP actually does
A managed security service provider (MSSP) is specifically in the business of security operations — threat detection and response, SIEM/SOC services, compliance-driven monitoring — often as their entire offering rather than one line item among many. MSSPs are evaluated by clients (and regulators, indirectly) on detection speed and incident response quality, which makes them a fundamentally more security-literate buyer than a generalist MSP.
Why this distinction matters for outreach
A vendor pitching a security tool to a generalist MSP often needs to build the case for why security matters as a service line at all. The same pitch to an MSSP can skip that step entirely and go straight into technical differentiation, since the buyer already lives in that world. Sending the same message to both without adjusting is a common reason reply rates look flat across a list that’s actually two different audiences.
FAQ
Can a company be both an MSP and an MSSP?
Yes — many larger MSPs have built out a dedicated MSSP practice or security division; our data tags firms with both designations where applicable.
Do you let me filter by MSP vs MSSP specifically?
Yes — this is one of the standard filters available on every segment; request a free sample to see it in the data.

Why the distinction matters for vendor targeting
The MSP/MSSP line has blurred in marketing copy but still matters operationally. A pure MSP is typically selling general IT management — help desk, patching, backup, uptime — as its core offer, with security as one line item among several. An MSSP (managed security service provider) has built its entire business around security operations: a SOC, threat monitoring, incident response, and often a dedicated compliance practice. Some firms genuinely operate as both, but treating every “MSP” contact as a security buyer, or every “MSSP” as a general-IT buyer, is exactly the kind of mismatch that tanks reply rates.
How to tell which one you’re actually contacting
Look at how the firm describes itself on its own site and directory listings, what certifications it holds (a SOC 2 report or a dedicated SOC points toward MSSP), and what its case studies emphasize. This site’s managed security services and managed IT services pages break down the segment further, and filtering your list by primary service focus — not just the word “MSP” in a firm’s name — produces a meaningfully more accurate first-campaign segment.
FAQ
Q: Is every MSSP also an MSP?
A: Not necessarily — some MSSPs are security-only shops with no general IT management offering at all, which matters if your product isn’t security-specific.
Q: Does this database distinguish between the two?
A: Yes, service focus is one of the filterable attributes in the full dataset — request a sample via the contact page to see it applied to a real export.
One more practical marker: pricing structure. Pure MSPs typically bill flat monthly per-seat or per-device rates; MSSPs more often bill a base security-operations fee plus incident-response retainers, reflecting the different cost structure of running a SOC versus a help desk.
