Gartner Top 10 Security Consulting Services Companies Ranked By Revenues

Related: Read the Top 100 MSSPs List and Research here.

Thousands of IT consulting firms offer security products and services. But which ones are the largest providers of security consulting services?

To answer that question, Gartner built a top 10 list of security consulting firms for 2016 based on annual revenues. But before we share the list, it's important not to confuse it with managed security services revenues and associated capabilities. After all, Gartner's Magic Quadrant for MSSPs in 2017 is strikingly different than the IT consulting list. The same goes for the Forrester Wave report for Top North America MSSPs. (Still, a handful of companies appear on multiple lists.)

Gartner Ranks Top Security Consulting Firms

Now, onto Gartner's Top 10 Security Consulting Services Firms list based on 2016 revenues in the sector. The 'recent moves' commentary after each company is from MSSP Alert rather than Gartner.
