Top Information Security Companies

Cybersecurity, a subset of information security, is a booming industry. Listed in this article are the top information security companies to watch out for. 

A recent study reported that the global cybersecurity market grew from $3.5 billion in 2004 to about $138 billion in 2017. The same study projects that such figures will reach $232 billion by 2022. Of course, we can’t say that these projections will be 100% accurate. Cybersecurity rapidly changes as new players come and go. 

However, these projections show that companies are desperate to protect their information against ever-evolving threats. Even COVID-19 can’t stop the uptick in cyberattacks. Thus, it is no wonder that the number of cybersecurity firms is increasing, too. Listed below are the top information security companies. 


KnowBe4 aims to deal with one of the root causes of cyberattacks – your employees. Due to our imperfect human nature, employees tend to make mistakes. This makes them the weakest link in your cybersecurity. KnowBe4 provides security awareness training to companies to solve that problem. 

In 2011, KnowBe4 hired Kevin Mitnick as the company’s Chief Hacking Officer. Mitnick was once the “World’s Most Wanted Hacker”. Today, he collaborated with KnowBe4 to develop state-of-the-art cybersecurity training programs. Hence, KnowBe4 aims to greatly increase the security awareness of employees against attacks, especially phishing. 


In 2011, George Kurtz and Dmitri Alperovitch founded Crowdstrike due to the massive increase in cyberattacks. CrowdStrike’s Falcon Platform offers the most advanced endpoint protection with expert intelligence. Thus, the platform can detect not only the malware but also the actors behind the attacks. 

Falcon is cloud-based and powered by artificial intelligence. Some of the many features the platform offers are IT hygiene, vulnerability assessment, and next-generation antivirus. Moreover, SC Magazine named CrowdStrike the Best Security Company for 2020. 


Fortinet’s co-founder and CEO Ken Xie has vast experience in entrepreneurship. In 1993, Ken started a network security company called SIS while studying at Stanford. In 1996, he started NetScreen to solve the performance limitations of firewalls running on PC/servers. 

Four years later, Ken and his brother co-founded Fortinet, one of the top information security companies. Fortinet has a strong and broad portfolio in security solutions, including:

  • Network
  • Edge
  • Cloud
  • IoT
  • Infrastructure

Moreover, Fortinet’s team is composed of respected tech innovators. Furthermore, the company has served 70% of Fortune 100 companies and many governments worldwide. Fortinet currently has 6,000 employees in 79 countries. 


Insider threats are one of the most common causes of cyberattacks. Such attacks may come from internal privileged users that abuse their level of access. Or it could be external attackers stealing privileges from users so they can operate stealthily as “privileged insiders”. Thus, both methods may cause huge damages to a business. 

CyberArk aims to prevent hackers from carrying out such attacks. They offer Privileged Access Management (PAM) solutions. These solutions aim to monitor, manage, and secure privileged access. Thus, CyberArk is one of the top information security companies committed to strengthening the weakest link in the cybersecurity chain.
