About the Author

Karthik Anchan is an SAP Security and GRC consultant whose expertise centers on protecting SAP landscapes and ensuring they meet governance and compliance requirements. Working across security and Basis functions, he helps organizations manage access, mitigate risk, and maintain the controls that keep enterprise systems secure.

His technical strength lies in SAP security administration. He is experienced in S/4HANA and Fiori role design, user administration, authorization troubleshooting, and role building through the Profile Generator. This hands-on capability enables him to design and maintain the authorization structures that determine who can access what within complex SAP environments.

Governance, risk, and compliance form an equally important part of his work. Within GRC Access Control, he handles access risk analysis, emergency access management, and access request management, along with the resolution of segregation of duties conflicts. This focus on controlling and monitoring access is central to keeping organizations both secure and audit-ready.

Compliance and audit support further define his contribution. He has worked on SOX controls, user access reviews, and the remediation of high-privilege access and firefighter IDs, providing the kind of support that helps organizations demonstrate strong governance during audits. His project experience also spans cutover activities, user acceptance testing, production support, and knowledge transfer.

His credentials include SAP certifications as a Security Administrator and a Fiori System Administrator, along with a Bachelor of Engineering. Drawing on this combination of hands-on security expertise and governance knowledge, Karthik Anchan writes to help readers understand how SAP security and GRC access control work in practice, how authorizations and risk controls are managed, and how organizations can protect their SAP systems while meeting the compliance standards their operations demand.
