Defence and security

Defence and security contracts sit under their own procurement regime, with clearance, security of supply, and information security requirements.

Defence and security procurement runs under a separate regime from general public procurement in almost every serious defence market. Success depends not only on capability and price, but also on security clearances, information-handling obligations, supply-chain assurance, industrial participation expectations, and strict adherence to formal procurement requirements.

Public buyers in this market are typically a country's ministry of defence or its armed-forces procurement organisation, alongside rescue and emergency services, border and coast guard authorities, security agencies, and multinational procurement bodies open to member and partner countries. Procurement may cover equipment and systems, framework agreements, sustainment and spare parts, maintenance and overhaul, training and simulation, and long-term in-service support.

For suppliers, the central challenge is to demonstrate a complete solution that meets the contracting authority's operational, technical, security, and commercial requirements. This requires clear evidence that the necessary clearances and information-handling arrangements are in place before bidding, that the supply chain can be assured, and that the capability can be delivered, sustained, and supported throughout the full contract period.

You sell defence and security solutions to public buyers

Defence and security procurement runs under a separate regime from general public procurement in almost every serious defence market. A supplier typically needs a security clearance before it can even access classified tender material, and clearance timelines have to start long before a specific opportunity appears. Security-of-supply and offset-style obligations recur across markets too, negotiated separately in each one.

Common procurement categories include:

Equipment, platforms, and integrated systems
Communications and secure information systems
Sensors, surveillance, and situational awareness
Protective equipment and personal kit
Sustainment, spare parts, and consumables
Maintenance, repair, and overhaul services
Training, simulation, and exercise support
Logistics, storage, and transport
In-service support and lifecycle management

Defence materiel: equipment, platforms, munitions, and any contract a buyer classifies as security-sensitive

Almost every jurisdiction runs this under its own dedicated regime rather than the general public procurement rules. In the EU, that regime is set by Directive 2009/81/EC, implemented through each member state's own national law. Check what the specific contract actually is before building a bid around the wrong rulebook.

NATO-agency business through NSPA

NSPA, the NATO Support and Procurement Agency, is the one genuinely multinational route in this sector: a single registration and procurement channel open to suppliers from NATO member and partner countries, running entirely independently of any single country's national procurement system. Registering with it is often the most direct way into defence-adjacent business for a supplier with no established footprint in any one country's national defence-industrial base.

Security-of-supply and offset arrangements

These recur in some form across most defence markets, even though the specific mechanism, and whether a given contract requires one, is negotiated separately in each country rather than standardised anywhere. Treat a buyer's question about this as a genuine, country-specific negotiation point.

How this market buys

Buyers in this category are typically a country's own ministry of defence or its armed-forces procurement organisation, running procurement under national defence-procurement law rather than the general public procurement rules. Clearance decisions typically run through a national security or intelligence authority, sometimes with a separate track for armed-forces-related assignments. NSPA, the NATO Support and Procurement Agency, sits alongside national channels as a genuinely multinational buyer and procurement route open to suppliers from NATO member and partner countries, and is often the most accessible entry point for a supplier without an existing national footprint.
