Explore the Role of a Pentester: This cybersecurity professional protects data by identifying system vulnerabilities through controlled attacks. Their expertise defends businesses against security breaches.
What is a Pentester?
The term “pentester” is a contraction of “penetration tester.” It refers to a cybersecurity expert specializing in finding security flaws in computer systems.
Serving as an ethical hacker, a pentester conducts controlled attacks to identify potential vulnerabilities. Their mission is to simulate intrusion scenarios, test the resilience of infrastructures, and produce a comprehensive report that allows companies to enhance the protection of sensitive data at risk from hackers and prevent cyberattack threats.
What are the responsibilities of a Pentester?
The pentester identifies security flaws and systematically exploits vulnerabilities in computer systems. They simulate controlled attacks through penetration tests on networks, applications, and infrastructures, assessing their resilience.
Their role is to anticipate cyberattacks by identifying weaknesses before malicious hackers do: They map out risk areas, analyze possible attack scenarios, and ensure the integrity of sensitive data.
Finally, they prepare a detailed report with recommendations and propose appropriate solutions to strengthen defenses and mitigate cyberattack risks.
In 2024, the cost of cyberattacks in France will hit $129 billion, underscoring the critical importance of this role.
