Quorum Cyber has ranked in 30th place this year in the 2025 MSSP Alert Top 250 – MSSP Alert’s annual list and research tracking the world’s top managed security services providers (MSSPs).
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 cybersecurity 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 cybersecurity across the wider global economy. In an ever-evolving market, the MSSP Top 250 sets a benchmark for service excellence and innovation and keeps organizations and decision makers informed about the breadth and quality of services available in the market.
MSSP Alert compares cybersecurity service providers on several criteria including:
- Annual recurring revenues
- Profitability
- Business growth rate
- Cybersecurity professional headcount
- Managed security services offered
- MSSP Alert’s editorial coverage of MSSPs worldwide
- Third-party industry honors from analysts such as Gartner, Forrester, and IDC
In 2025 Quorum Cyber continued to build momentum for a new phase of growth for 2026 and beyond. The company launched its new Threat Division, made several exciting Executive Appointments, and won a string of Prestigious Awards. All this on top of integrating its two major acquisitions: Difenda and Kivu Consulting.
New Threat Business Unit
In January 2025, the business launched its new Threat business unit and appointed Paul Caiazzo as Chief Threat Officer. As a cybersecurity engineer, entrepreneur, and strategist with over 27 years’ experience, Paul brings a wealth of knowledge and expertise to the role, having previously developed cybersecurity businesses from the ground up. The Threat division of Quorum Cyber covers threat intelligence, threat hunting, incident response and ransom negotiations. The team is trusted by regulated sectors, has Preferred Vendor Status with over 40 insurance companies, and has established law firm partnerships with top boutique and full-service law firms.
Strengthened Leadership Team with New Senior Appointments
Quorum Cyber also strengthened its leadership team in 2025 with several senior appointments:
- Chief Revenue Officer (CRO) Mike LaPeters joined the business with 30 years’ experience in building and leading sales and marketing organizations and channels for security, storage and infrastructure software products.
- Stacey Sweeney brings nearly 30 years of cybersecurity marketing leadership experience to the Chief Marketing Officer (CMO) role. In her career to date, she has built high-performing teams to shape and revitalize brands.
- With more than two decades of senior leadership experience in the enterprise technology sector, Melissa Webb’s role as Vice President – Microsoft Partnership will drive and grow Quorum Cyber’s strategic partnership globally.
- And, as a seasoned risk and cybersecurity executive with over 25 years’ experience, John Bruce joined as the company’s Chief Information Security Officer (CISO) to further strengthen defenses across the business.
Awards and Recognition
In April 2025, Quorum Cyber won the Microsoft Security MSSP of the Year 2025 award at the Microsoft Excellence Awards. It also reached the finals of two more categories: Data Security & Compliance Trailblazer, and Security Changemaker. And for the second consecutive year, it was named as a Finalist in the 2025 Microsoft Security Partner of the Year awards, in November.
This month the company was named as a Microsoft Security Excellence Awards Finalist for Data Security & Compliance Trailblazer and Security Service Partner of the Year. Quorum Cyber has been named as a finalist in at least two categories at the Microsoft Security Excellence Awards since 2023, showing remarkable consistency in providing the highest standards of service delivery and satisfaction to customers worldwide.
Quorum Cyber was awarded Managed Security Service Provider of the Year at the CyberSecurity Breakthrough Awards 2025 in October and won Cybersecurity Company of the Year at the Scottish Cyber Awards 2025 in February.
With the Microsoft partnership being one of the pillars of the company’s success, Quorum Cyber also achieved the Identity and Access Management Specialization from Microsoft this year. As a Microsoft Solutions Partner for Security, the company now holds all four available Microsoft Security specializations: 1) Threat Protection, 2) Cloud Security, 3) Information Protection and Governance, and 4) Identity and Access Management. Building on this, in October Quorum Cyber was named as a proud participant of both the Microsoft Security Store Partner Ecosystem and the Microsoft Sentinel Partner Ecosystem.
