Port of London Authority

The Port of London Authority runs the tidal River Thames - 95 miles of the UK's busiest inland waterway - as a self-funding trust port with no shareholders and no parent company to fall back on. Harbour masters and pilots keep commercial and leisure traffic moving around the clock, which means the operational surface here isn't abstract: navigation and pilotage services, marine services, hydrography, port development and environmental monitoring all run continuously, and the data behind them supports real decisions about where ships go and how the river is managed.

The threat model follows from that. Navigation safety, hydrographic survey data, water quality and ecology monitoring, and the infrastructure investment and engineering programs that underpin them span both operational technology and ordinary enterprise systems. Planning, finance and environmental science teams sit alongside harbour masters, pilots and engineers, so anything touching the river's data has users in disciplines that don't think about security first - and can't afford to stop work when systems don't behave. Governance splits between a Board of Directors handling strategy and oversight and an Executive Committee running day-to-day operations, which shapes how security decisions get escalated and funded.

Work here sits inside a public-benefit mandate: surpluses are reinvested in the tidal Thames region, and delivery runs on partnership with industry, government and environmental groups. The organization pairs a historic public trust structure with ongoing investment in skills, technology, infrastructure and decarbonisation. Domains in scope include hydrography, navigation safety, marine services, port development, environmental science and ecology, water quality improvement, engineering, planning and decarbonisation - a wide, multidisciplinary estate, operated 24/7 across the Thames estuary and the wider UK maritime sector.
