What is Penetration Testing?
Penetration testing (pen testing) is the process of simulating cyberattacks on computer systems, networks, and applications to find security weaknesses before real hackers do.
Why is Penetration Testing Important?
🔹 Prevents Data Breaches – Identifies vulnerabilities before they are exploited.
🔹 Ensures Compliance – Meets cybersecurity regulations like PCI-DSS, HIPAA, and GDPR.
🔹 Tests Security Defenses – Assesses the effectiveness of security controls.
🔹 Helps Companies Stay Secure – Protects sensitive data from hackers.
Penetration testers use various tools, techniques, and hacking methodologies to identify vulnerabilities and provide security recommendations.
