By identifying and attempting to breach weaknesses in an existing system, Penetration Testers help organizations resolve security vulnerabilities and weaknesses. These systems include websites, data storage systems, and other IT assets. This testing simulates cyberattacks and other breaches designed to access valuable sensitive data. Pen Testers can then document their actions to generate detailed findings and remediation reports.

Penetration Testers need an advanced knowledge of operating systems and scripting and/or coding tools, as well as networking and network protocols like TCP/IP, UDP, ARP, DNS, and DHCP. Penetration Testers also need experience with computer languages like Python, Powershell, and Golang, and common pen testing tools like Kali, Metasploit, Wireshark, and Web Inspect. They also need a deep understanding of exploits, vulnerabilities, and the latest trends in cyber breaches.
