PCI DSS 4.0 introduced important changes to penetration testing requirements: Requirement 11.4 now emphasises testing from both inside and outside the network, segmentation testing must verify isolation of the cardholder data environment, the methodology must cover industry-accepted approaches, and the customised approach option allows organisations to demonstrate security through alternative controls that meet the objective. The transition deadline has passed, and all organisations must now comply with 4.0 requirements including updated penetration testing scope and methodology.
