Largest Cybersecurity M&A Deals in 2017 (CSO)


The cybersecurity market — estimated to be worth more than $1 trillion over the next five years — is simultaneously expanding and consolidating.

CSO previously provided a list of the largest cybersecurity VC deals in 2017. At least 20 companies have raised $40 million or more from venture capital firms and corporate investors so far this year (not including recent Q4 deals). Dozens of other cybersecurity startups have pulled in smaller rounds during the first three quarters.

The cybersecurity space is dotted with new market entrants, and the trend is expected to continue through 2021. A total addressable market — TAM, as VCs like to call it — with 12 zeroes equates to a lot of investment activity.

On the other hand, the market is being somewhat equalized by a slew of mergers and acquisitions over the past two years.
