Case Study: Independent Communications Authority of South Africa achieves secure, compliant email management with Mimecast

Mimecast provides streamlined Email Management to ICASA

The Independent Communications Authority of South Africa (ICASA), the government regulator for telecoms, broadcasting and postal services, needed a stable, compliant email system for its ~400 users. Its legacy GroupWise infrastructure was prone to outages, lacked central archiving and search, struggled with growing spam and viruses, and risked losing vital records when staff left — creating major regulatory and operational risks.

Mimecast’s Unified Email Management, deployed alongside Afrovation, delivered a cloud-based archive, security and continuity solution that integrated with ICASA’s environment and eased migration to Exchange. The deployment produced a searchable archive (including former employees’ mail), robust content-based filtering to prevent data leakage, significant reductions in spam and viruses, improved uptime and support, and cost-effective compliance and productivity gains.
