Requirements to sell to the Spanish defence sector: certifications, security clearances and first steps

Understanding the requirements to sell to the Spanish defence sector is usually more important than chasing a tender too early. Industrial and technology suppliers first need to clarify their offer, route to market, security obligations and procurement readiness.

Not every company needs the same certifications or clearances. A software company, an engineering firm, a component manufacturer, a communications provider or a maintenance specialist may face very different requirements. Before discussing certificates, the company should first clarify what it wants to sell, to whom, in which type of programme and with what level of sensitivity.

There is no single requirement to enter the defence market

A common mistake is to assume that there is a closed checklist of certificates required to sell to defence. In practice, requirements depend on the activity, the contract, the end customer, the type of information involved and whether the company acts as prime contractor, subcontractor or technology partner.

A company may need commercial preparation, technical solvency, administrative documentation, information security, quality certifications, public registers, electronic procurement readiness or industrial security clearances. But not everything is mandatory from day one.

1. Clarify what capability the company wants to sell

Before reviewing certifications, the company must define precisely what capability it brings to the defence sector. It is not enough to say that it has technology, engineering or advanced manufacturing. That capability must be translated into real defence problems and use cases.

What product, service or technology is being positioned.
What operational, industrial or technological problem it solves.
What previous references can be demonstrated.
What maturity level the solution has.
What adaptation may be required for a defence environment.
What type of customer, integrator or prime contractor may need it.

This translation matters because many requirements only become clear once the opportunity is defined: a public contract, a partnership with a prime contractor, a classified programme, an ICT service or an industrial supply agreement.

2. Prepare for public procurement

When the route to market involves public tenders, the company must be ready to use Spain’s Public Sector Procurement Platform, review tender documents, monitor opportunities and submit electronic offers when required. For a deeper view of this route, review how to prepare for defence tenders in Spain through the Public Procurement Platform.

In practice, this means preparing aspects such as electronic certificates, powers of representation, administrative documentation, solvency evidence, electronic signature and an internal process to respond to short deadlines.

The key point is not simply to register on a platform. The company needs a repeatable process to assess opportunities, decide whether to bid, prepare documentation and avoid formal mistakes.

3. Consider the Spanish Defence Industry Register managed by DGAM

The Spanish Defence Industry Register, historically associated in business language with DGAM, can be relevant for companies that want to position themselves as current or potential suppliers of equipment, materials or services required by the Spanish Armed Forces.

According to the Spanish Ministry of Defence, the register provides a database to identify the industrial, technical, financial and production capabilities of registered companies. It can therefore be a useful institutional visibility tool for companies that want to be recognised within the Spanish defence industrial ecosystem.

However, it should not be seen as a sales guarantee or as a substitute for commercial strategy. Being listed in a register may help, but it does not replace positioning, relationships with integrators, proposal preparation or programme knowledge.

4. Understand HSEM, HSES and HPS when classified information is involved

Defence security clearances in Spain, including HSEM, HSES and HPS, are among the most sensitive areas for companies that want to participate in programmes, projects or contracts involving classified information.

In simplified terms:

HSEM: Company Security Clearance. It is the formal recognition of a contractor’s capacity and reliability to generate and access classified information up to a specific level. Importantly, HSEM alone does not authorise the company to handle or store that information at its own facilities.
HSES: Facility Security Clearance. It may be required when a company that already holds HSEM needs to handle or store classified information at its own authorised facilities.
HPS: Personal Security Clearance. It applies to specific individuals who need access to classified information.

The Spanish Ministry of Defence states that HPS applies to people in companies who need access to classified information in classified programmes, projects or contracts. It also indicates that, when classified information must be stored at company facilities, HSES may be required in addition to HSEM.

The practical conclusion is clear: these clearances should not be requested “just in case”. The company should first understand whether a specific opportunity involves access to classified information, what classification level applies, who requires it and at what stage of the programme it becomes necessary.

5. Review ENS, ISO 27001 and cybersecurity requirements for digital services

Spain’s National Security Framework, known as ENS, may be relevant when the company provides digital services, processes information in systems linked to the public sector or participates in ICT projects subject to security requirements. Royal Decree 311/2022 regulates the ENS and establishes the applicable security framework in the field of electronic administration.

However, it is important not to oversimplify: not every company that wants to sell to defence needs ENS certification. It depends on the contract, the service, the affected system, the customer and the tender requirements.

In parallel, certifications such as ISO 27001 may add credibility in information security management, especially for companies working in software, communications, sensors, cybersecurity, data or systems integration. But they should be prioritised according to the target market, not because they are fashionable.

6. Consider quality standards, PECAL/AQAP and industrial requirements

In certain defence supplies, developments or services, quality requirements may be particularly important. Many companies already have ISO 9001 or other sector-specific standards, but defence opportunities may refer to specific standards such as PECAL or AQAP depending on the contract and customer.

They will not always be essential at the beginning, but it is useful to know whether the target segment commonly requires them. A company aiming to join the supply chain of major prime contractors should review not only public tenders, but also the supplier qualification requirements of potential industrial customers.

7. Build a roadmap before investing in certifications

The main recommendation is not to start by spending money on certifications without a clear strategy. The steps should be ordered first:

Define the capability to be brought to the defence sector.
Identify relevant segments and potential customers.
Analyse whether the main route will be public procurement, a prime contractor, an integrator, a European programme or an industrial partnership.
Review administrative, technical and security requirements in comparable opportunities.
Prioritise registers, certifications and clearances according to business probability.
Prepare commercial and technical documentation adapted to the language of the defence sector.
Activate relationships with partners, associations, public bodies and integrators.

This roadmap avoids two common problems: arriving too late to an opportunity because the documentation was not ready, or investing in requirements that do not bring immediate commercial value. This article is an initial strategic guide and does not replace the legal, technical or administrative review of each specific tender, contract or programme.

Common mistakes when preparing to enter the defence sector

Assuming that being listed in a register automatically leads to sales.
Requesting certifications without knowing which opportunities require them.
Failing to distinguish between administrative, technical, quality and security requirements.
Approaching a tender without basic documentation already prepared.
Ignoring the role of prime contractors and systems integrators.
Presenting the company with a generic message rather than clear defence use cases.
Forgetting that some defence opportunities have long commercial cycles.

When defence consulting can help

Defence consulting can help an industrial or technology company distinguish between what is essential, what is useful and what is secondary. The goal is not to accumulate certificates, but to prepare a realistic market-entry path.

This includes reviewing capabilities, identifying opportunities, prioritising certifications, assessing registers, preparing documentation, understanding public procurement and building a commercial strategy adapted to the defence sector.

If your company wants to sell to the Spanish defence sector, the first question should not be “which certificate do we need?”, but “which opportunity do we want to pursue and what requirements separate us from it?”.
