What Is Penetration Testing (Pentest) in Cybersecurity?

Pentest (Penetration Test) is a legal and controlled simulated attack carried out to reveal the security vulnerabilities of systems. The aim is not to "harm the system" but to find and close weak points before attackers do.

Pentest Process (Summary)

• Reconnaissance: Understanding the target surface (domains, services, versions)
• Scanning: Detecting vulnerabilities and misconfigurations
• Exploitation Attempt: Verifying the real impact of the vulnerability (in a controlled manner)
• Reporting: Risk level + remediation steps + prioritization

Why Should You Have One Done?

Most attacks are not "sophisticated"; they are the exploitation of known vulnerabilities. Pentests turn the question "Could it happen?" into "If it happens, from where?" and make security measurable: risk, impact and action.
