TEMPEST shelters: emission security per project
TEMPEST is the discipline of keeping an emission inside. The shelter contributes the shielded volume, the separation and the filtered services; the level and the accreditation belong to the programme and its national security authority.
Levels and zoning
The shelter is engineered to the NATO SDIP-27 level the programme names, inside the SDIP-28 zoning of the site. The zoning decides how much the shelter must attenuate; the level decides what the equipment inside may emit.
Red/black separation
Red (classified) and black (unclassified) circuits are separated in the layout, the cable routes and the point of entry, so no black line runs beside a red one.
Filtered power, fibre-only data
Power enters through filters at the single point of entry; data enters on fibre only. The same chain that gives the EMC and EMP shielding gives the emission security.
Accreditation
A TEMPEST shelter is accredited by the national security authority per project, on the shelter as built with the equipment it carries. Tanax does not accredit and does not hold a TEMPEST certificate; it builds to the requirement and supports the accreditation.

Questions procurement asks
Who accredits the shelter?
The national security authority of the customer's country, per project, on the shelter as built with its equipment.
Is a TEMPEST shelter also an EMP shelter?
The shielded enclosure, the gasketed door, the waveguide vents and the single point of entry serve both. The EMP protection is engineered to MIL-STD-188-125-2; the TEMPEST level is specified per project.
Send the requirement. The shelter is engineered to it and measured against it.
Frequency range and attenuation, TEMPEST level and zone, protection level, climate and carrier: name them and the engineering starts. The specification sheet comes with the reply.

- Military CommandSpecial-purpose shelters to NATO standards, built by a defence manufacturer that also builds and services military trucks.
- EMC and EMP shieldingA shielded shelter is only as good as its weakest aperture. The chain below is read the way a programme engineer reads it: the enclosure, every aperture, the point of entry, the grounding, and the measurement that proves it.
- CBRN collective protectionCollective protection keeps the inside clean while the outside is not: a filtered overpressure, an airlock to pass through and seals that hold.
- Ballistic and blastArmour is a level the customer names and a laboratory verifies. Tanax brings the armoured truck cab work: the panels, the liners and the doors that take a round or a blast.
- Mobility and transportA shelter that cannot move is a building. Every Tanax shelter carries ISO 1496 corners and moves by truck, hooklift, rail or sling; air-transportable sizes and expandable shelters are engineered on request.
- Environment and signatureThe shelter is engineered for the climate it is sent to and for how little of it should be seen: in daylight, in infrared and at night.
- Armoury containersA weapon store is a security cage first and a container second. Tanax has engineered one from a written specification before; this page is the build.
