Enterprise penetration testing: find the breach before an attacker does

Penetration testing is an authorized, simulated cyberattack against an organization's systems, performed by security professionals to identify exploitable vulnerabilities before real attackers do. It involves manual exploitation, not just automated scanning, to confirm what an attacker could actually achieve.

Vulnerability scanning uses automated tools to identify known vulnerability signatures and is typically run frequently as a baseline check. Penetration testing involves manual exploitation by security professionals to confirm which vulnerabilities are actually exploitable and what real-world business impact they would have, typically run periodically or after major changes.

Costs vary by scope: a focused web application or API test can range from a few thousand to tens of thousands of dollars, while a comprehensive engagement covering network, application, cloud, and social engineering testing typically ranges higher, depending on environment size and complexity.

Most organizations should conduct penetration testing at least annually, and additionally after major infrastructure or application changes. Organizations subject to PCI DSS or similar regulatory frameworks are typically required to test annually and after significant changes as a condition of compliance.

Black box testing simulates an external attacker with no prior system knowledge. Gray box testing gives the tester partial knowledge, such as a standard user account, simulating an insider or compromised-credential scenario. White box testing gives the tester full access to source code and architecture for the most thorough, code-level review.
