What is a Penetration Tester? 

A penetration tester is an information security professional who identifies potential security risks within an organization's computer networks. Given the heightened cybersecurity risks in many industries, these threats to network integrity are prevalent, making penetration testers a crucial asset to any IT team. 

Penetration testers may find employment within a company, offer freelance services to business clients, or join a specialized firm that provides penetration testing services to large-scale enterprises.

Penetration testers typically work in an office setting but may also have the flexibility to work remotely from home or off-site. While some maintain regular work hours, others may work overtime and extended shifts during nighttime, weekends, and holidays, contingent upon project demands and organizational needs. 

A penetration tester's key responsibilities encompass:

  • Conducting threat assessments for organizations and crafting reports for stakeholders and IT personnel.
  • Assessing existing security protocols and delivering recommendations for system enhancement.
  • Executing penetration tests on software, networks, and various IT infrastructure components.
  • Specifically testing networks to pinpoint existing vulnerabilities.
  • Providing support to network administrators in mitigating potential threats.
  • Staying current on evolving hacker tactics and methods for infiltrating vulnerable systems.
  • Establishing incident response teams to address security breaches.
  • Generating reports on potential losses to demonstrate the impact of security issues on other departments.
