Segmentation Penetration Testing

Segmentation Penetration Testing is a focused security assessment designed to verify that network segmentation controls are effectively isolating systems and data as intended. It is especially important in environments where critical systems (e.g., payment processing, industrial control systems, or sensitive databases) are separated from other network zones using firewalls, VLANs, or access control lists.

This test simulates how an attacker or malicious insider might attempt to traverse from a less trusted network segment (such as a user workstation) to a more restricted segment (such as the PCI zone or production environment). Segmentation testing is often a compliance requirement under standards like PCI DSS, which mandates the validation of segmentation controls to reduce the scope of audits and security risks.

Whether you're securing a cardholder data environment (CDE), managing third-party access, or isolating high-value systems, segmentation testing ensures that your defenses are actually working.
