From Remote Access to a Critical Access Platform

Replacing Oracle Secure Global Desktop: Delta Air Lines Builds a Critical Access Platform

‍Delta Air Lines, one of the world's largest airlines, faced a strategic challenge: replacing its entire remote access infrastructure built on Oracle Secure Global Desktop. Over three years, Delta fully replaced this legacy environment with VISULOX — using the transition to turn a basic access path into a modern Critical Access Platform for secure access to critical systems.

Why replace Oracle Secure Global Desktop?

‍Legacy remote access infrastructures hit their limits as security requirements rise. Oracle Secure Global Desktop gave Delta basic remote access but lacked the core security capabilities that a highly regulated operation handling sensitive data now requires as standard. Rather than simply extending the existing solution, Delta chose a future-proof platform — and a measurable gain in security.

More than a migration: building the Critical Access Platform

‍The transition was not a simple one-to-one migration. In the course of replacing the old solution, all security capabilities the previous solution lacked were deliberately added. The result is a true Critical Access Platform: a platform that centrally controls privileged access (Privileged Access Management), secures every session, and makes it fully auditable. All administrative access runs through a single, secured point — with no direct network access to the underlying systems.

Secure access to performance and passenger data systems

‍Administrative access to performance and passenger data systems is among the most sensitive areas of an airline. Delta administrators access these systems in the US securely through the platform. Clear access control based on the least-privilege principle, continuous logging, and complete auditability ensure every access is controlled and verifiable at any time.

The result: higher security level, future-proof platform

‍With VISULOX, Delta Air Lines has not only replaced outdated infrastructure — it has meaningfully raised its security level for access to critical systems. The Critical Access Platform combines Secure Remote Access, central control, and complete auditability, providing a robust foundation for the secure operation of critical systems that scales with future requirements.
