Penetration Testing, or “pentesting” for short, is a valuable service for businesses and organizations of all sizes. It involves trying to access a system, website, or service illegally in order to expose any vulnerabilities that hackers can exploit. This allows IT departments and the people that protect the organization’s data to see those security issues before anyone malicious does. A Penetration Tester can help an organization keep their systems securely running by tackling any issues they discover while testing their systems.
