Part-time penetration testers evaluate the security of a computer network, website, application, database, or another type of computer system by attempting to breach the network. Unlike full-time employees, part-time penetration testers work thirty hours or less per week. In this role, you assess vulnerabilities in computer systems by attempting to hack into the network using the same techniques as a cyber hacker, and then you report on your findings to your client or employer. You also help respond to a known network threat or security breach. You may work on the staff of a technology firm or within a company's IT department, or you may be an independent contractor who works with many different clients.
