Sabre Corporation

Sabre Corporation has been running critical infrastructure for global travel since 1960 - back when reservation systems were mainframes and the threat surface was a locked room. Now the company processes billions of transactions annually across 160+ countries, connecting airlines, hotels, and travel agencies through its SabreMosaic platform. That scale means the attack surface is vast: PII at rest and in transit, payment data flowing through distributed systems, and the uptime expectations of an industry where downtime isn't an inconvenience - it's a cascading operational failure. The technical stack spans computerized reservation systems, intelligent retailing engines, and seamless distribution layers that touch every leg of a travel booking. Security here isn't perimeter defense; it's embedded in platforms handling real-time transaction processing across a fragmented global ecosystem with varying regulatory regimes - GDPR, PCI-DSS, and country-specific data residency laws all in play simultaneously. Headquartered in Southlake, Texas, Sabre operates at the intersection of legacy infrastructure modernization and cloud-native transformation. For security engineers, that means working with both - hardening systems that have been running for decades while securing new platform builds designed for personalized travel experiences at global scale. The threat model includes fraud vectors, API abuse, supply-chain risk from interconnected partners, and the operational complexity of defending a system where availability is non-negotiable.
