Millions of Attacks
The world is inundated with hundreds of millions of cyberattacks every year targeting private industry, government and individuals. Every hour of the day, thousands of software agents of all variety scan the Internet looking for vulnerabilities in computers and servers (see bot). Datacenters that hold sensitive information such as banks, Wall Street firms and the military are especially bombarded 24/7 to find an unguarded entry point.

Billions in Damage
Although companies are loathe to publicize data breaches, millions of records are stolen every year by criminal gangs and government espionage. The stolen data are sold on the Dark Web each year making billions of dollars for the attacker and causing substantial damage to the victims.
