GlobalProtect to ZTNA Transformation

Confidential Technology Sector

Context

A global technology company with a large distributed workforce and extensive partner ecosystem. Traditional VPN architecture created bottlenecks, broad network access, and complex partner connectivity management. Legacy VPN infrastructure was struggling to meet performance, security, and user experience requirements.

Challenge

Replace aging VPN infrastructure with a modern Zero Trust Network Access solution supporting thousands of remote users and partners while improving security posture and reducing operational overhead. The traditional VPN created broad network access creating security risks.

Approach

Executed a phased migration from GlobalProtect to Zero Trust Network Access (ZTNA), enabling per-application, identity-aware access with centralised visibility. Designed integration patterns with existing identity providers and created comprehensive runbooks.

Delivery

The transformation was delivered over 16 weeks, including architecture design, pilot deployment, staged rollout, and full production deployment with monitoring and support.

Outcomes

Significant attack surface reduction

Per-application access replaced broad network access, reducing risk dramatically

Enhanced user experience

Least-privilege access patterns eliminated VPN performance constraints

Reduced support tickets

Self-service capabilities reduced helpdesk load substantially

Legacy & Sustainability

Phased migration roadmap, security baselines, and automated rule clean-up processes to maintain policy currency.
