Zero Trust Security Architecture for a Regional Bank

Challenge

A regional bank with 1,200 employees faced escalating phishing incidents and lacked centralised identity governance across 14 branch locations. The CISO had no consolidated view of access rights or privileged accounts.

Solution

We designed and implemented a Zero Trust identity framework using Microsoft Entra ID, conditional access policies and privileged identity management across all endpoints and applications. A phased rollout minimised operational disruption.

Business Outcome

94% reduction in unauthorised access incidents within 6 months. Board received monthly security posture dashboard for the first time.

✓94% reduction in access incidents
✓Zero downtime during rollout
✓Monthly board security dashboard
✓Full POPIA access compliance achieved

Business Intelligence Platform for a Healthcare Network

Challenge

A healthcare group with 8 facilities operated on siloed systems with no consolidated view of patient flow, resource utilisation or financial performance. Leadership made decisions based on weekly PDF reports that were already 5 days old.

Solution

We built a unified Power BI analytics environment connected to EHR, finance and operations systems, giving executives real-time visibility across all facilities. A data governance framework was established to ensure accuracy and trust.

Business Outcome

Executive reporting time reduced by 70%. Bed utilisation improved by 18% through better capacity planning.

✓70% reduction in reporting time
✓18% improvement in bed utilisation
✓Real-time multi-facility dashboards
✓Unified data governance framework

Education

Digital Workplace Transformation for a University

Challenge

A South African university with 15,000 students was operating on legacy infrastructure that could not support hybrid learning. Staff productivity was hampered by disconnected systems and students had inconsistent access to digital resources.

Solution

We designed and oversaw a full Microsoft 365 implementation — including Teams, SharePoint and OneDrive — underpinned by a modern identity and device management framework. Staff training was embedded throughout the programme.

Business Outcome

100% of academic staff moved to digital-first workflows within 8 months. Student satisfaction scores improved by 32%.

✓100% digital-first staff adoption
✓32% improvement in student satisfaction
✓Secure access from any device or location

IT/OT Security Assessment for an Industrial Group

Challenge

A large manufacturing group had never formally assessed the security of its operational technology environment. Following a ransomware incident at a peer company, the board requested urgent clarity on their exposure.

Solution

We conducted a comprehensive IT/OT security assessment across 4 production facilities, identifying 37 critical vulnerabilities and mapping attack paths from corporate network to production floor. A prioritised remediation roadmap was delivered to the board within 6 weeks.

Business Outcome

All critical vulnerabilities remediated within 3 months. The board approved a R8 million security investment programme based on the risk-quantified roadmap.

✓37 critical vulnerabilities identified and remediated
✓Board-approved R8M investment programme
✓OT network fully segmented from IT
✓Ongoing OT monitoring capability established
