Proficiency with tools such as Burp Suite, OWASP ZAP, and scripting languages (e.g., Python) is typically required. Excellent analytical thinking, problem-solving skills, and clear client communication set top testers apart. These skills and qualifications are vital to accurately identify threats, deliver actionable reports, and maintain client trust in a constantly evolving security landscape.
