In a digitally hyperconnected world, our increasing reliance on the internet means lots of potential new problems — chief among them malicious cyber attacks that can lock us out of our computers, hold ransom our most sensitive files or even siphon our bank accounts

The greater the number of new technologies and platforms we use to conduct our digital (and, sometimes, physical) lives — from smartphone apps to cloud computing software to pacemakers — the more we become vulnerable to privacy attacks. And it’s hard to predict where these attacks will come from. 

Cyber invasions have national security ramifications as well. As quoted in a Cybersecurity and Infrastructure Security Agency advisory, Rob Jones, NCA Director General for Cyber, explains, “Cyber attacks have evolved and increased in scale and severity over recent years, with the criminal groups behind them targeting the critical infrastructure of countries around the world.”  

Cyber attacks can also interfere with major elections. The U.S. was famously hit by one in 2016 and France in 2017. Many fear we’ll see more election hacking in years to come.

Why Cybersecurity Is Important

Businesses are especially vulnerable to large-scale breaches that swipe or corrupt valuable data. Because of this, there’s an immediate need to protect ourselves online. This is why cybersecurity has taken center stage in recent years.

Citing a 2021 Euroconsumers report, the World Economic Forum noted that hackers today use connected devices to stage massive DDOS attacks, “the likes of which have been used to bring down banking and even healthcare networks.”  

A Zion Market Research study shows that the global cybersecurity market has followed suit, reaching a value of $139 billion in 2021, while on track to hit $210 billion in 2028. Larger organizations may be better equipped to invest in cybersecurity resources, but the benefits of cybersecurity far outweigh the costs of cyber attacks for all companies.

Not surprisingly, as businesses ramp up efforts to keep their data and systems safe, the number of cybersecurity firms that provide those services is rising. Cybersecurity funding reached record levels in 2021, swelling beyond $20 billion. It seems companies are finally taking concrete steps to address data breaches, creating an environment where cybersecurity companies can thrive.
