20 Public Cybersecurity Companies Being Traded Today
In a digitally hyperconnected world, our increasing reliance on the internet means lots of potential for 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.
“For most smart devices being made, there’s likely someone in the world reverse engineering it to see how to get in,” Rebecca Herold, CEO of The Privacy Professor, said recently. “This includes implanted medical devices, where privacy and security concerns are significant."
Cyber invasions have national security ramifications as well. As NSA Head Admiral Michael Rogers warned, a worst-case cyber strike on the U.S. could involve “outright destructive attacks focused on some aspects of critical infrastructure” — perhaps power grids or banking systems.
Cyber attacks can also interfere with major elections. The U.S. was famously hit by one in 2016 and France in 2017. Security experts believe we'll see more of the same in years to come.

Protecting businesses with cybersecurity
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.
Valued at $120 billion in 2017, the global cybersecurity market is estimated to exceed $300 billion by 2024, according to a Global Market Insights report. That same report says cybersecurity for enterprise-level companies accounts for 60 percent of the market. But seeing as the average large company loses $10 million annually from security breaches, it’s money well spent.
While smaller companies are smaller targets, they’re also susceptible to cyber assaults.
According to Brian NeSmith, CEO of Arctic Wolf Networks, “Small organizations are finally realizing that they need to be as prepared as large organizations when it comes to cybersecurity. We will see small businesses’ approach to cybersecurity impacting larger organizations through the supply chain vector. Hackers will take advantage of smaller organizations, which often fuel larger business’ supply chains, because they typically have security vulnerabilities that can be more readily exploited than larger ‘targeted’ 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. In 2018 alone, venture capitalists spent $5 billion backing them — a 20 percent hike from 2017.
“We’re seeing mega-breaches happening on an extremely frequent basis,” Chris Ahern, a data scientist and principal at Strategic Cyber Ventures, told Reuters. “I don’t think that’s going to stop anytime soon. And investors are seeing that as an opportunity for investment.”
