Top 200 MSSPs for 2019: Companies 10 to 1

10. Atos
Paris, France

Atos in 2019 launched a cybersecurity services portfolio for health care organizations.


9. DXC Technology
Tysons, Virginia, USA

DXC inherited some MSSP services from an HP Enterprise business purchase. The company’s latest offering is Applications Security on Demand — a consumption-based applications security testing service powered by Micro Focus.


8. Orange Cyberdefense (acquired Securelink)
Nanterre, Paris, France

Orange in May 2019 acquired SecureLink, one of Europe’s largest MSSPs offering cybersecurity consulting, integration, managed detection and response (MDR) services.



7. Secureworks
Atlanta, Georgia, USA

Secureworks has been expanding into multiple MSSP sectors, partnering with various software providers along the way. But even as a leading MSSP, Secureworks offers an important reality check for the entire market. For instance, overall revenues are growing less than 10 percent year over year, proving that scaling an MSSP is difficult.


6. Alert Logic

Alert Logic continues to expand its SIEM-oriented threat management services. The company has also been building a partner program for MSPs, VARs and systems integrators.


5. Herjavec Group
West Hollywood, California, USA

Herjavec Group remains one of the most active MSSPs in the world. Over the past few months the company has opened a 24×7 facility in India; boosted SOC operations in the U.S.; expanded identity managed services across Canada, UK and the US; confirmed a partnership with Google Cloud Chronicle; and plenty more.


4 Trustwave
Chicago, Illinois, USA

Parent Singtel essentially bet its worldwide cybersecurity and MSSP business on Trustwave. In late 2019, Singtel integrated its own cybersecurity capabilities, technologies and resources and those associated with Optus and NCS into a single global brand operating under Trustwave.



3. NTT (acquired WhiteHat Security)
London, UK

NTT Security has global reach, and gained deep application security provider expertise by acquiring WhiteHat Security earlier this year. The deal made headlines at the RSA Conference.


2. AT&T Cybersecurity
Dallas, Texas, USA

AT&T had a strong MSSP practice long before acquiring AlienVault in 2018. Fast forward to present day, and an AT&T Cybersecurity division offers MSSP services directly to Global 2000 companies, while empowering peer MSSPs with AlienVault’s SOC-oriented software.


1. IBM Managed Security Services 
Armonk, New York, USA

IBM Security spans managed, cloud, consulting and other services. The technology giant’s key moves and milestones for 2019 include: Introducing security for SAP and ERP applications; and bolstering IBM Security Connect, a cloud-based community platform that extends the capabilities of IBM’s security products.
