Port security: Greece
Greece's ports concentrate national and regional trade in small, exposed footprints scattered across the mainland and the islands, each vulnerable from the water, the air and the network at once. Securing those gateways end to end, where a single busy harbour handles flows an economy depends on, is a layered problem no single measure addresses.
A gateway exposed from several directions
A working port is open by design: approaches crowded with traffic, a waterline that cannot be sealed, and an operating network that ties cranes, gates and manifests together. Passive radar addresses the near-shore threat that overhead sensors miss, while vessel monitoring from orbit tracks what approaches from seaward, including craft running dark. Together they give the port authority awareness of the water it sits on, from the harbour to the far approach.
Air and network layers a busy harbour cannot ignore
Above and behind the waterline sit two further exposures: the low-cost drone that can surveil or disrupt a terminal, and the operating technology that a busy port cannot run without. Counter-UAS defence tuned to small, slow targets protects the airspace over the quay, while maritime cybersecurity hardens the systems that keep cargo and vessel movements coordinated. Because these capabilities come from independent, non-aligned makers, the protection of a gateway an economy depends on is accountable to the national authority rather than to an outside supplier.
How engagement works in Greece
As an independent, non-aligned prime vendor, Unstrat fields one accountable team that secures the busiest gateways first (water, air and network together), then extends the model to the ports the islands rely on, operated by the port authority itself. Equipment and services are end-use certified and sustained in-region. Localisation arrangements are scoped per programme, subject to export controls and end-use approvals.
Securing the gateways end to end
A programme opens with a briefing on how Greece's ports are exposed from several directions at once: a waterline that cannot be sealed, airspace over the quay, and the operating network that ties cranes, gates and manifests together. Before any representation is offered, end-use is certified and export-control approvals are settled, so protection of gateways an economy depends on stays accountable to the national authority. Capability is matched to how a working port actually runs: passive radar for the near-shore threat overhead sensors miss, satellite vessel monitoring for what approaches from seaward including craft running dark, counter-UAS tuned to small, slow targets over the quay, and maritime cybersecurity for the systems that keep cargo and vessel movements coordinated. Fielding is phased with in-region sustainment, securing the busiest gateways (water, air and network together) first, then extending the model to the ports the islands rely on, operated by the port authority itself. Localisation arrangements are scoped per programme, subject to export controls and end-use approvals.

Greece's maritime domain is among the most fragmented anywhere: a scatter of islands, straits and long approaches across the Aegean that no chain of coastal radar can watch as a whole. Building a single picture from the beach out to the edge of the exclusive economic zone is a scale and geometry problem before it is a sensor problem.
Problem pagePiracy raises insurance costs, deters shipping and endangers seafarers. Space-based vessel monitoring, aerial patrol and hardened port and vessel systems let coastal states detect threats early and protect the shipping lanes their economies depend on.
Problem pageGreece's essential services span a mainland grid and the island systems that depend on interconnections and local generation across water, so critical infrastructure is a first-order target from the network and the air alike. Control systems built for reliability rather than for adversaries carry particular weight where an island cannot easily fall back on a neighbour.

A single picture of a nation's waters, orbit to harbour, for EEZ enforcement, illegal-fishing detection and port security, held on national tasking rather than a coalition's.
Solution page →Power, water, transport and port systems assessed, hardened and watched continuously, by a team with no foreign government to report the findings to.
Solution page →Greece: security context
Greece's maritime geography shapes its priorities: domain awareness across the Aegean, surveillance of an exclusive economic zone dotted with islands, monitoring of borders and migration routes, and protection of critical infrastructure. It is an environment where scattered waters and long approaches demand persistent, wide-area awareness.
An accountable single-channel engagement gives Greece a coherent counterpart for those priorities: Aegean maritime domain awareness, EEZ and island surveillance, border monitoring and infrastructure protection. A defence ministry gains end-use certified equipment, disciplined export-control handling and localisation arrangements scoped per programme rather than promised in advance.
About this challenge
Ports concentrate national trade in a small, exposed footprint, vulnerable from the water, the air and the network. Inshore passive radar, vessel monitoring from orbit, counter-drone defence and maritime cyber protection secure the gateway end to end.
Frequently asked questions
Why does port security in Greece need several layers at once?
Because a port is exposed from the water, the air and the network simultaneously: the waterline cannot be sealed, drones can overfly the quay, and the operating systems cannot be taken offline. Passive radar, satellite monitoring, counter-UAS and maritime cyber cover it end to end. We would be glad to brief your team on securing the busiest gateways first.
What does non-emitting passive radar add over overhead sensing?
It addresses the near-shore threat around the quay without radiating a signature an adversary can locate or jam, resolving the small craft and surface contacts that satellites cannot pick out, completing the picture from the harbour to the far approach.
Who controls the protection once fielded?
The national port authority. All the layers come from independent, non-aligned makers, so protection of the gateway stays accountable nationally, with localisation arrangements scoped per programme and subject to export controls and end-use approvals.
