Prison security: South Africa
South Africa's correctional facilities face a modern breach that a wall was never built to stop: small drones flying contraband over the perimeter, and incarcerated networks that keep operating through smuggled phones. With organised crime deeply woven into some custodial populations, that airborne and spectrum threat undermines the isolation on which custody depends.
Walls that no longer contain the threat
Small drones now fly phones, drugs and weapons directly over prison perimeters to waiting inmates, a route no fence addresses. Counter-UAS screens the airspace over the wall, detecting and defeating the drones that make the deliveries, while modular aerial platform kits and fixed sensing strengthen the perimeter picture on the ground. A smuggled phone is not a nuisance but a breach: it lets an incarcerated network coordinate outside associates and plan escapes.
Organised networks operating from inside
The distinctive South African dimension is the depth of organised-crime involvement in some facilities, so custodial control is contested through the spectrum as much as at the gate. Defended communications protect the links between the facility and its control room against jamming or compromise, and close the channels an escape attempt would otherwise run through. Because the counter-drone, surveillance and communications layers come from independent, non-aligned makers, the custodial authority controls the whole picture without a foreign supplier's conditions.
How engagement works in South Africa
Unstrat engages South Africa as an independent, non-aligned prime vendor: one accountable team, end-use certified, sustained in-region. A programme typically begins by screening the airspace over the highest-risk facilities, then extends perimeter and communications protection and hands operation to correctional teams. The non-aligned position matters because custodial security is a core state function that should answer to national command alone.
Restoring isolation the wall no longer keeps
Because organised networks contest custodial control through the airspace and the spectrum as much as at the gate, an engagement opens with a briefing on the highest-risk facilities and the airborne and communications threats a wall was never built to stop. Export-control and end-use approvals are confirmed before any representation, keeping the whole picture under the correctional authority's own hand. Capability is matched to real conditions: Counter-UAS screening the airspace over the perimeter against small drones flying contraband, surveillance strengthening the ground picture, and defended communications protecting the links between facility and control room against jamming or compromise. Sustainment is phased in-region, extending from airspace screening to perimeter and communications protection as correctional teams take over. Localisation arrangements are scoped per programme, subject to export controls and end-use approvals. The advantage protected is the isolation custody depends on; the mission is a core state function answering to national command.

Adjacent priorities in South Africa
Cheap unmanned aircraft now threaten airports, energy sites, borders and public events in every region. Layered counter-UAS, combining detection radar tuned to small slow targets, passive sensing and defeat systems, is the affordable answer recent conflicts demand.
Problem pageProtecting leadership and mass public events now means defending airspace measured in metres and communications measured in milliseconds. Deployable counter-drone systems and protected communications extend the security perimeter into the air and the spectrum.
Problem pageSouth Africa's long land borders with Zimbabwe, Mozambique, Botswana, Namibia and Lesotho, together with its busy ports, create many routes for contraband and untaxed goods to move where surveillance is thinnest. The cumulative loss to customs is fiscal, but the erosion of control over remote frontier stretches is strategic.

Layered defence against hostile unmanned aircraft: detection, tracking and defeat priced for the mass threat rather than a missile economy that empties the magazine first.
Solution page →Hardened control systems, security that works with the network down, and inspection that certifies the physical estate, the unglamorous half of national defence that decides the loud half.
Solution page →South Africa: security context
South Africa's priorities span sea, infrastructure and networks: maritime domain awareness across busy waters, protection of critical infrastructure, and defence of a financial sector exposed to cyber threats. It is an environment where economic weight raises the stakes of every domain.
One accountable, non-aligned partner gives South Africa a coherent counterpart for that capability: maritime domain awareness, infrastructure protection and financial-sector cyber defence through a single channel, with transparent export-control handling. A security agency gains end-use certified equipment and localisation arrangements scoped per programme rather than promised in advance.
About this challenge
Drones deliver contraband over prison walls, and coordination of escapes increasingly runs through compromised networks. Counter-drone screens, perimeter surveillance and defended communications close the modern gaps in custodial security.
Frequently asked questions
How does counter-drone defence apply to South African prisons?
Small drones fly contraband directly over prison walls to inmates, a route no fence stops. Counter-UAS screens the airspace over the perimeter, detecting and defeating those deliveries, while perimeter surveillance covers the ground. We would be glad to brief your team on screening the highest-risk facilities first.
Why are defended communications part of prison security here?
Because organised networks operate from inside some facilities through smuggled phones and can coordinate escapes through channels the prison cannot see. Defended communications protect the links between the facility and its control room and close the spectrum the threat relies on.
Who controls this capability once deployed?
The correctional authority does. Because the counter-UAS, surveillance and communications layers come from independent, non-aligned makers, custodial security stays under national control without a foreign supplier's conditions.
