Zero-Trust Network Segmentation & Statutory Compliance Audit

Remediating network vulnerabilities and aligning controls with Zimbabwe Data Protection requirements

The Challenge

An unsegmented flat network allowed any workstation access to member transactional databases. The organisation required an objective technical evaluation to mitigate ransomware risk and meet statutory data protection compliance.

The Technical Approach

Performed a non-invasive vulnerability assessment, redesigned the corporate switching topology into isolated VLAN tiers, deployed stateful firewall inspection, and enforced role-based access controls for core databases.

Objective Technical Review

Financial and member services organisations face heightened statutory scrutiny and sophisticated threat actors. Operating with a flat network exposes all internal assets once a single endpoint is compromised.

Methodology Executed

HiTa Synergy engineered an isolated network architecture with granular packet inspection between client workstations, member service portals, and back-office financial ledger databases.

MEASURED IMPACT
