Border surveillance: Greece
Greece's frontiers combine mountainous land borders in the north with maritime approaches threaded through the islands, so the border problem is really two problems that must share one picture. Turning that mixed frontier into a monitored line, across terrain and water that both favour the crosser, is a coverage problem, not a manpower one.
A frontier of mountains and sea approaches
Northern land borders through high, wooded terrain and river lines sit alongside sea approaches where crossers move between islands and along the coast, and neither can be held by a patrol line alone. Passive radar contributes coverage without emitting a signature that reveals where the watch begins and ends, on land and over water alike, while persistent drone surveillance classifies contacts across ground and channels a patrol cannot see into, so a response is ordered against a confirmed track rather than a rumour.
Posts and vessels that must share one picture
Awareness across a mixed land-and-sea frontier is only useful if dispersed posts and craft see the same track at the same time, which means resilient links between them that an adversary cannot read or spoof. Secure communications hold that shared picture together, so a sensor cue in a mountain sector or a channel reaches the unit that can act on it. Because the sensing and communications layers come from independent, non-aligned makers, the frontier picture is tasked on national priorities and retained under national control rather than routed through an outside partner.
How engagement works in Greece
As an independent, non-aligned prime vendor, Unstrat fields one accountable team that begins by closing the sectors, on land or between islands, where the frontier is most open, then fuses passive, aerial and communications layers into a single picture the border authority operates itself. Equipment is end-use certified and sustained in-region. Localisation arrangements are scoped per programme, subject to export controls and end-use approvals.
One picture across two very different frontiers
A programme opens with a briefing that treats Greece's frontier as the two problems it really is (mountainous land borders in the north and maritime approaches threaded through the islands) and identifies the sectors, on land or between islands, that are most open. Before any representation is offered, end-use is certified and export-control approvals are settled, so the accountable single channel carries only what the border authority is cleared to operate. Capability is matched to both domains at once: passive radar that adds coverage without emitting on land and over water alike, persistent drone classification that reaches into mountain ground and island channels a patrol cannot see, and secure links so dispersed posts and craft share one track. Fielding is phased with in-region sustainment, closing the most open sectors first to protect the interior, then fusing the layers into a single monitored line the border authority runs itself. Localisation arrangements are scoped per programme, subject to export controls and end-use approvals.

Adjacent priorities in Greece
Contraband, fuel and untaxed goods cross borders wherever surveillance is thinnest, draining customs revenue. Wide-area overhead surveillance and low-observable radar coverage let enforcement concentrate where the traffic actually moves.
Problem pageTrafficking networks exploit the scattered maritime approaches around Greece's islands, moving people across open water in unsafe craft at terrible human cost. Finding those vessels early, before an approach becomes a rescue emergency, is a persistent, wide-area awareness problem across waters no patrol can watch continuously.
Problem pageTerrorist and insurgent networks exploit remote terrain, porous borders and unprotected communications. Persistent ISR, protected tactical communications, counter-drone defence and cyber protection give security forces a decisive information edge, from a supplier with no political agenda attached.

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
Long land borders across remote terrain cannot be watched by patrols alone. Layered surveillance, using passive radar that emits nothing, persistent drone coverage and secure communications between posts, turns a porous frontier into a monitored one, under sovereign control.
Frequently asked questions
Why is Greece's border effectively two problems?
Because mountainous land frontiers in the north sit alongside maritime approaches threaded through the islands, and neither can be held by a patrol line alone. Layered passive and aerial sensing fused into one picture covers both. We would be glad to brief your team on closing the most open sectors first.
How does the same sensing work on land and over water?
Passive radar adds coverage without emitting on land and sea alike, while persistent drone surveillance classifies contacts across mountain ground and island channels a patrol cannot see into, one picture across two very different frontiers.
Who controls the border picture this produces?
The national border authority. The sensing and communications layers come from independent, non-aligned makers, so the frontier picture is tasked and retained nationally, with localisation arrangements scoped per programme and subject to export controls and end-use approvals.
