One of the most powerful cybersecurity testing strategies a company of any size can implement is called a penetration test.  Cyber threats and data breaches have increased dramatically over the last few years, and cyber criminals have advanced skills, tools and the ability to exploit critical data and systems. A penetration test, or pen-test , is a controlled exercise that simulates a malicious hacking attack on a computer system, network, application or device and is performed to help evaluate the cybersecurity controls that are in place, that defend the system, device or application.
