Annual MSP 501 Ranking Recognizes Leading Technology Providers Driving Business Growth Through Innovation, Operational Excellence, and Strategic IT Leadership

JUNE 27, 2026 – Reliable Technology Services (RTS), a Maryland-based managed IT and cybersecurity provider, has been named to the prestigious 2026 MSP 501 list, recognizing the world’s top managed service providers for operational excellence, financial performance, innovation, and long-term business sustainability.

The MSP 501 is widely regarded as one of the technology industry’s most respected benchmarks for managed service providers. Unlike rankings based solely on company size or revenue, the MSP 501 evaluates organizations based on a comprehensive set of criteria, including recurring revenue, profitability, operational maturity, and the ability to deliver consistent value to clients.

For Reliable Technology Services, this recognition reflects the company’s continued commitment to helping small and mid-sized organizations use technology not simply as infrastructure, but as a strategic business asset. Through proactive IT management, cybersecurity, cloud solutions, and executive-level technology consulting, RTS partners with organizations to reduce risk, improve productivity, and support long-term business growth.

“The 2026 MSP 501 winners represent the highest-performing and most innovative IT providers in the industry today. Everyone wants to be a 501 because they stand head and shoulders above the competition,” said Robert DeMarzo, Vice President of Content, Channel Events. “Today’s managed services organizations serve as the backbone to the world’s small, medium, and large organizations, and the MSP 501 sets the standard for all other MSPs. These managed service providers aren’t just keeping pace with the industry—they’re actively shaping the future of managed services. Making the MSP 501 list is a testament to their commitment to operational excellence, innovation, and their ability to deliver exceptional value to their clients in an increasingly complex technology landscape.”

The MSP 501 has recognized the world’s top-performing managed service providers for nearly two decades through a rigorous evaluation process developed in collaboration with industry experts, the MSP Summit Board, and previous MSP 501 honorees. The methodology rewards organizations that demonstrate strong financial health, operational efficiency, recurring revenue growth, and sustainable business practices.

MSP Summit is pleased to name Reliable Technology Services to the 2026 MSP 501.

“We’re thrilled to be recognized as one of the top MSPs in the world! This award is a huge shout out to our incredible team. They’re the ones who work tirelessly, always putting our customers first and coming up with creative, out-of-the-box solutions to tough tech problems. We love finding new ways to help our clients’ businesses grow with the latest technology. This win is for them,” said Lenny Giller, President, RTS.

“The MSP 501 represents far more than a ranking—it’s the definitive benchmark for excellence in the managed services industry, and a reflection of our unwavering commitment to serving the channel community,” said Kelly Danziger, General Manager, Channel Partners and MSP Summit. “Our team works year-round to provide the insights, connections, and platforms that empower MSPs to grow and thrive in an ever-evolving market. Backed by the power of Informa, a global leader in live events, digital platforms, and research, we leverage unparalleled industry expertise and data-driven intelligence to deliver programs like the MSP 501 that truly matter. This recognition celebrates not just the achievements of these exceptional providers, but the collaborative ecosystem we’ve built together to drive the channel forward.”

This year’s MSP 501 list represents one of the most competitive classes in the program’s history.

The MSP 501 organizations collectively represent some of the most successful and innovative managed service providers in the world, delivering strategic technology services across cybersecurity, cloud, AI, networking, collaboration, help desk, and managed operations. This year’s honorees averaged more than $32 million in revenue, with recurring revenue accounting for nearly 60% of total business revenue.
