TT-Line GmbH & Co. KG

TT-Line GmbH & Co. KG runs the infrastructure it operates on. The Lübeck-based ferry company moves nearly 1 million passengers and more than 500,000 freight units a year across the Baltic Sea, connecting Germany, Poland, Lithuania, and Sweden with a fleet of nine modern Ro-Pax ferries. That is a distributed, cross-border operation: ticketing and passenger data flows, freight logistics coordination, port and terminal processes, and vessel operations all sit on the same commercial backbone. The threat model is the one common to maritime transport - availability of booking and logistics systems during continuous sailings, protection of passenger records across four national jurisdictions, and the growing overlap between corporate IT and shipboard operational technology. The company has been at this for over 60 years and employs more than 900 people from 33 nations, so the environment is long-lived, multilingual, and multinational rather than greenfield. Systems have accreted around an operating fleet that doesn't pause for maintenance windows; freight customers depend on schedule reliability, and roughly a million guests a year pass through the digital front door. Sustainability is central to the stated mission - environmentally conscious sea transport is the company's stated direction - which increasingly means data-driven efficiency work alongside the operational stack. Roles here sit at the intersection of maritime transport, freight logistics, and sustainable shipping, spanning the Baltic Sea region. The work is less about defending a single data center and more about securing an operating company: passenger services, Ro-Pax freight flows, and the corporate systems that keep nine vessels running on schedule across four countries.
