As mainstream support for legacy SAP ERP platforms ends on December 31, 2027, organizations face increased cybersecurity risks during their transition to SAP S/4HANA. The migration process, which often spans multiple years, involves complex hybrid infrastructures that expand the attack surface significantly. Companies must ensure secure connectivity to external partners without exposing S/4HANA to potential threats. The ISG Provider Lens report highlights that enterprises in Asia Pacific are accelerating their SAP modernization efforts while focusing on system stability and minimizing risks associated with data migration. Challenges include managing insecure data transfers and maintaining compliance with varying regulatory environments across regions. The urgency for robust security measures is underscored by the need for organizations to modernize their security architecture alongside their ERP transformations. Failure to address these challenges could lead to significant operational disruptions and data breaches.
