Renaissance Energy Africa emerged following the landmark $2.4 billion acquisition of Shell’s Nigerian onshore business, instantly becoming one of Nigeria’s largest indigenous upstream oil and gas operators.

Microsoft 365 E5 delivers an integrated security and compliance platform that enables organizations to implement Zero Trust principles across identity, endpoint, and data layers while enabling secure AI adoption.

For Volta River Authority (VRA), Ghana’s national power utility and critical infrastructure operator, Reliance Infosystems delivered a unified Microsoft 365 E5 transformation aligned to the Microsoft Cybersecurity Reference Architecture.

The engagement shifted VRA from fragmented, legacy security controls to a governed, cloud-native security and compliance model that now protects identities, endpoints, and sensitive data across the enterprise.

This transformation was designed not only to improve security posture but also to establish the foundational governance required for safe rollout of 500 Microsoft 365 Copilot licenses.

“Reliance Infosystems’ ability to unify complex security controls and modernize endpoint management enabled VRA to establish a robust, AI-ready Zero Trust foundation without compromising the performance of Ghana’s critical power utility.”
