Top 100 Managed Service Providers in North America

What Is a Managed Service Provider?

A managed service provider (MSP) takes over day-to-day IT for a business so it does not need a large in-house team. The MSP monitors systems, fixes problems before they cause downtime, and supports employees, usually for a flat monthly fee per user or device instead of hourly break-fix charges. Managed service providers range from local firms serving small businesses to global companies serving the Fortune 500, and the Top 100 managed service providers above are the largest in North America.

Managed service providers typically cover:

• Network and server management: 24/7 monitoring, maintenance, and updates
• Cybersecurity: endpoint protection, threat detection, and compliance (see the MSSP list and the top 100 cybersecurity companies)
• Cloud services: AWS, Azure, Google Cloud, and Microsoft 365 management
• Helpdesk and backup: end-user support, data backup, and disaster recovery

Why Choose a Top Managed Service Provider

The MSPs listed here represent the largest, most experienced, and most innovative providers in North America. They offer enterprise-grade infrastructure, 24/7 support, and specialized expertise across cloud platforms, cybersecurity, industry compliance, and digital transformation. Whether you need a global partner or a regional specialist, these Top 100 MSPs have the scale and expertise to manage complex IT environments.

From Enterprise to Mid-Market to Local MSPs

The Top 100 includes three categories: large global providers (Accenture, IBM, Capgemini) serving Fortune 500 companies with $1M+ annual IT budgets; mid-market specialists (Rackspace, Insight, CDW) serving 100–1,000 employee firms with $50K–$1M budgets; and innovative regional providers serving SMBs with faster on-site support and flexible pricing. Whether you need enterprise-scale infrastructure or personalized SMB service, this list has providers at every tier.

Which Tier Is Right for Your Business?

The right tier on this list depends entirely on your organization's size and IT budget, not just brand recognition:

• Large global providers (Accenture, NTT DATA, Leidos) make sense for Fortune 500 companies with $1M+ annual IT budgets needing global delivery and deep bench strength across every technology domain.
• Mid-market specialists (CDW, Rackspace, Insight) fit 100–1,000 employee organizations with $50K–$1M budgets that need breadth of services without enterprise-scale overhead.
• Regional and specialized providers typically serve SMBs best, offering faster on-site response and more flexible, negotiable contract terms than any name on this Top 100 list. If that's your business, our best MSP companies ranking and MSP Near Me locator are better starting points than a national Top 100.

How This List Differs from Other Top MSP Rankings

Other "top MSP" lists CloudTango's annual rankings, MSP 501-style industry awards are often built from self-submitted surveys, peer nominations, or vendor sponsorships, which rewards marketing effort as much as actual scale. This list is built directly from verified firmographic data instead: real revenue, employee counts, and founding years rather than submission-based scoring.

Neither approach is "wrong" a survey-based list can surface strong regional players that pure scale-based ranking misses but if you're specifically trying to identify the largest, most established managed service providers by verifiable size, that's what this list is built to do. For a broader universe of MSPs and MSSPs beyond the top 100 by scale, see the full MSP list or MSSP list.

Methodology: How We Ranked the Top 100

This list is built from verified company data, annual revenue, employee count, headquarters location, and founding year drawn from our directory of 180,000+ managed service providers across North America. Companies are ranked primarily by scale (revenue and employee count) rather than by self-reported awards or vendor-sponsored placements, which is why this list leans toward large global integrators and established mid-market specialists rather than the newest or most heavily marketed providers. For context on the broader market this list is drawn from, the managed services industry in the US includes tens of thousands of providers.
