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 cybercriminals 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.
