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.
