Another way to thwart cyberattacks is to increase the number of cybersecurity experts, McGladrey says. According to the 2017 cybercrime report from the Herjavec Group, cybersecurity firms estimate such crimes are going to cost about $6 trillion annually by 2021. Companies are experiencing shortages in qualified applicants for cybersecurity jobs. The U.S. Department of Commerce estimates there are now about 350,000 unfilled positions, and that number is only going to increase. McGladrey says.
