HTM

HTM operates the public transit network for The Hague - trams, light rail, and buses moving hundreds of thousands of people daily. That's a massive, always-on attack surface: payment systems, vehicle control software, operational infrastructure. The company runs OVpay, the Netherlands' contactless debit-card check-in system, which means they're custodians of financial transaction data at scale. They're also rolling out next-gen TINA trams with modern onboard tech stacks.

Founded in 1864, HTM is a 2,000-person operation with over 160 years of institutional history. That kind of longevity in critical infrastructure means legacy systems layered under modern platforms - a complexity profile that keeps things interesting. They've been named the best city transport operator in the Netherlands, with a 7.9 customer satisfaction rating, so uptime and reliability aren't aspirational; they're contractual.

The threat model here spans payment fraud, OT/IT convergence risks across fleet management systems, and the usual enterprise perimeter concerns at municipal scale. Cybersecurity roles likely touch payment security for OVpay, hardening of embedded vehicle systems, and securing the operational technology that keeps the network running. All based in The Hague, Netherlands.
