7 Best Cybersecurity Stocks to Buy Right Now
Twenty-five years ago cybersecurity simply meant antivirus software and computer firewalls. The internet has grown dramatically since then, and the cybersecurity industry has grown along with it.
What we used to call the World Wide Web now encompasses a massive, global digital communications system, expansive cloud computing platforms, and digital networks that drive almost every aspect of international business, investing and finance. In that relatively short period of time, the world has transformed from mostly analog to almost completely digital. The benefits have been incredible but the risks have also increased.
Today, cybercriminals pose a tremendous threat to individuals and businesses of every size. There’s a virtual army of hackers, ransomware attackers and scammers out there trying to infiltrate systems and steal money and valuable data. It’s the mission of cybersecurity companies to stand in their way.
That’s why, according to research by Fortune Business Insights, cybersecurity is a $250 billion industry projected to reach a market size of half a trillion dollars by 2032. The rapid growth of the cybersecurity industry is the result of an ever-increasing number of highly sophisticated cyberattacks and the implementation of strict data protection laws that became necessary to protect our critical digital economy.
It’s also why smart investors are loading up on cybersecurity stocks. The growth of the cybersecurity segment of the technology sector has been truly impressive and, as we continue to increase our reliance on digital infrastructure, it shows no signs of slowing down. In short, as cyberattacks become more prevalent and more sophisticated, cybersecurity will become more indispensable.
