The cybersecurity industry is quickly expanding in response to the need for increased computer security. Here are the 10 top publicly traded cybersecurity companies according to the Cybersecurity Ventures 500 list.


The cybersecurity industry is a quickly expanding market, growing in response to the rapidly developing need for computer security.

Like the report highlights, plenty of new cybersecurity companies are coming onto the scene, including mergers and agreements, as well as investments and initial public offering activities. In sum, the release states that these additions are “constantly changing the vendor and service provider landscape.”

With that in mind, here, the Investing News Network (INN) profiles the 10 top public cybersecurity companies on the most recent Cybersecurity 500 list.  The companies below are publicly traded across a range of stock exchanges.

  • As Cyber Security market is quickly expanding, New Companies will follow the footsteps of those top 5 Cyber Security Companies.

  • Thank you for listing these top Cyber security companies.As we know cyber security companies are expanding day by day for security purposes for small and large business enterprises. I would also like to add Transputec Ltd as a security service provider in this list . We are using there cyber security services since 2005 for our business.

    • Transputec looks like an interesting company Matt, but we focus on companies that our audience can consider investing in. Doesn’t look to me like Transputec is a public company.

  • Any idea why ManTech was left out of the cybersecurity500? They’ve been hiring a lot recently and got awarded large government contracts.

  • Sorry, but this list is TOTALLY WRONG!!!

    BlackBerry is the #1 CyberSecurity company in the WORLD!!! It should not be listed as #34 !!! That’s TOTAL CRAP! The person who compiled this list should be LINED UP and SHOT!!!

    BlackBerry’s common shares are listed on the NASDAQ Stock Market (NASDAQ: BBRY) and the Toronto Stock Exchange (TSX: BB).
