The problem
Environment provisioning, session management and resource monitoring, designed for security, multi-tenancy and concurrent workloads.
Customer and operations dashboards with backend services for parcel lifecycles, tracking events and notifications, built for high-throughput transactional workflows.
South African legal information is scattered across portals with limited keyword search, while international e-discovery platforms are often priced beyond the local market.
