Penetration Tester

A Penetration Tester — often called an ethical hacker — is hired to attack an organisation's systems, networks, and applications before malicious actors can. Day-to-day work involves scoping engagements with clients, running structured attacks using tools such as Metasploit, Burp Suite, and Nmap, documenting vulnerabilities discovered, and writing clear reports that translate technical findings into business risk. Penetration testers work across web applications, internal networks, cloud infrastructure, and increasingly physical and social engineering scenarios.
