Secure SAP S/4HANA Migration: Top 4 Challenges Companies Must Address
Zscaler Blog, Friday, May 1st, 2026
SAP S/4HANA migrations face four critical security challenges including partner access, data exfiltration, manufacturing connectivity, and SaaS outbound traffic.
As SAP ERP platforms approach end-of-support deadlines, companies are migrating to S/4HANA, creating complex hybrid infrastructures that span multiple years and environments.
The article identifies four major security challenges: securely providing partner access without exposing S/4HANA, protecting sensitive data during migration across on-premises and cloud environments, securing manufacturing floor connectivity while preventing lateral threat movement, and safely managing outbound SaaS traffic without data leakage.
Traditional security approaches using firewalls and VPNs struggle to scale in these hybrid environments, leading companies to adopt zero-trust architectures that enforce least-privilege, identity-based access controls across all connections.
