What is Penetration Testing?
Penetration testing (pen testing) is the practice of simulating cyberattacks against your systems to identify exploitable vulnerabilities before real attackers do.
Penetration testing (pen testing) is the practice of simulating cyberattacks against your systems to identify exploitable vulnerabilities before real attackers do. Unlike vulnerability scanning (automated tool-based), pen testing involves skilled security professionals actively attempting to breach your defenses.
Pen test types: black box (tester has no prior knowledge), gray box (tester has partial knowledge like API docs), and white box (tester has full knowledge including source code). White box testing is most thorough but takes longer.
Common findings: injection vulnerabilities (SQL, command, LDAP), authentication bypass, API security gaps (rate limiting, authorization), data exposure through verbose error messages, and privilege escalation.
Pen testing frequency: annually at minimum, plus after major releases or infrastructure changes. Cost ranges from $5,000-50,000+ depending on scope and depth.
Why It Matters
Pen testing reveals real-world exploitable vulnerabilities that automated tools miss. Many compliance frameworks (SOC 2, PCI DSS, HIPAA) require periodic penetration testing.
Frequently Asked Questions
