MSSP Alert has ranked Quorum Cyber at 30th place in its annual managed security services provider (MSSP) league table.

The company has jumped 20 places from its ranking of 50th in 2024 and, since 2022, has risen by almost 120 positions. The rating is a measure of the company’s range of managed cyber security services and the types of cyber incident it has handled in the past 12 months, along with its revenue and headcount figures.

MSSP Alert is one of the leading online resources that reviews and assesses MSSPs and how they contribute to cyber security across the wider global economy. In an ever-evolving market, the MSSP Top 250 sets a benchmark for service excellence and innovation and keep organisations and decision makers informed about the breadth and quality of services available in the market.

This recognition follows on hot on the heels of Quorum Cyber being recognised as a Microsoft Security Excellence Awards finalist for Data Security & Compliance Trailblazer and Security Service Partner of the Year and just weeks after the company was named as a Finalist of 2025 Microsoft Security Partner of the Year.

MSSP Alert compares cyber security service providers on several criteria including:

• Annual recurring revenues
• Profitability
• Business growth rate
• Cyber security professional headcount
• Managed security services offered
• MSSP Alert’s editorial coverage of MSSPs worldwide
