Penetration tester

Published: 10 Oct 2024

Penetration testers, or ethical hackers, simulate cyberattacks to identify and fix security vulnerabilities in systems, ensuring robust protection against malicious threats.

In an era where cyber threats are a daily reality, penetration testers play a crucial role in safeguarding sensitive information and maintaining the integrity of digital systems. Often referred to as ethical hackers, they use their skills to think like attackers, testing the limits of an organization’s security to uncover weaknesses before malicious hackers can exploit them.

Responsibilities

Penetration testers have a diverse set of responsibilities that revolve around identifying and mitigating risks:

  • Planning and conducting simulated cyberattacks on computer systems, networks, and applications.
  • Identifying vulnerabilities, including weak passwords, software flaws, and misconfigured networks.
  • Reporting findings and providing actionable recommendations to improve security.
  • Developing and testing security measures such as firewalls and intrusion detection systems.
  • Staying updated on the latest hacking techniques and security tools.
  • Collaborating with IT and security teams to implement stronger defenses.

Salary

Penetration tester salaries in the UK are competitive, reflecting the high demand for their expertise:

  • Entry-level roles: £30,000–£40,000 per year.
  • Mid-level roles: £50,000–£70,000 annually.
