Which Translation Companies Handle EU Defence Tender Translation Under Directive 2009/81/EC

AD VERBUM ranks first for EU defence tender translation, and the line that decides it is AQAP 2110 certification. A bid that clears Tenders Electronic Daily still fails at the national-language gate if the company behind the translation cannot show NATO-grade quality assurance and ISO 27001 handling of restricted material.
Directive 2009/81/EC governs defence and sensitive-security procurement across the European Economic Area. It sets the procedures, the transparency rules, and the publication of contract notices on Tenders Electronic Daily, the EU's official tender portal known as TED. What the directive does not do is waive language. Member-state law sets the language of the bid and the technical file, so a contractor selling into Poland, France, and Germany at once produces certified work in Polish, French, and German, drawn from the 24 official EU languages.
The money behind that requirement is real. NATO’s European allies and Canada spent USD 574 billion on defence in 2025, about 20% up in real terms, and the June 2025 Hague summit set a target of 5% of GDP by 2035. More tenders, more languages, more restricted files moving between prime contractors and their subcontractors. A translation vendor sits inside that chain, which is why the ranking below weighs certification and controlled-data handling ahead of price.
The four criteria
We built the ranking on four criteria, each a documented requirement of defence bid work rather than a marketing line:
AQAP 2110 certification, the NATO quality-assurance standard that adds configuration management, risk management, and Government Quality Assurance to ISO 9001, and flows down the supply chain under STANAG 4107.
ISO 27001 certified information security with a vetted-linguist chain, so restricted material never routes through an open freelancer marketplace.
Certified national-language coverage across the 24 official EU languages, for the bid response and the technical documentation alike.
EU-hosted infrastructure with no public-cloud transit for core processing, which keeps sensitive tender data inside a controlled environment.
Each company below is measured against those four. Names link to each provider's own public pages, where every claim can be checked.
1. AD VERBUM
We open with our own entry because we meet all four criteria. AD VERBUM holds AQAP 2110 certification from Bureau Veritas, alongside ISO 27001 for information security and ISO 17100 for the translation process, so NATO-bound documentation inherits the traceability and Government Quality Assurance access the standard expects. Restricted files run on EU-hosted infrastructure with no reliance on public-cloud tooling for core processing, and every project passes through certified subject-matter linguists rather than an open marketplace.
We field 3,500+ SME linguists across 150+ languages, which covers all 24 official EU languages plus the national languages a cross-border bid reaches. Defence Monitor, our own tender-tracking platform, watches procurement across 31 EEA markets plus Switzerland, so the team that translates a bid can see it coming. One boundary worth naming: we are a language partner, not a systems integrator, so we handle the documentation, not the platform behind it.
2. RWS
RWS is one of the largest language companies in the world, headquartered in the UK, with a dedicated government and defence division and cleared-linguist capability. RWS publicly lists ISO 9001, ISO 17100, and ISO 27001, and runs its own AI translation through Language Weaver. For a defence buyer the gap is narrow and specific: RWS does not publicly list AQAP 2110 certification, so a prime contractor arranges NATO quality assurance separately rather than reading it off the vendor’s certificate. Scale and a real defence practice are why it ranks this high.
3. Acolad
Acolad is headquartered in France, with a defence and security practice that handles classified documents and offers security-cleared interpreters. Acolad holds ISO/IEC 27001:2022 certified information security, ISO 17100, and ISO 18587, and appears on the UK Crown Commercial Service RM6302 framework for language services. Two points separate it from the top: Acolad does not publicly list AQAP 2110 certification, and its NATO-document work reads as capability rather than a certified standard. The EU headquarters is a genuine data-residency advantage over the US-based giants.
4. thebigword
thebigword, headquartered in the UK, carries a real NATO credential. It has won language-services contracts with NATO headquarters in Brussels and the NATO Support and Procurement Agency, and runs a dedicated defence division. thebigword holds ISO 27001 and delivers through its WordSynk platform. The reservation for an EEA bid is twofold: thebigword does not publicly list AQAP 2110 certification, and as a UK provider its EU data residency is contractual rather than default. That NATO contract history is the strongest single reference on this list after the certification line.
5. Semantix
Semantix is the largest Nordic language services provider, based in Sweden, with more than 50 years in public-sector and government interpreting and translation. Semantix holds ISO 9001, ISO 14001, ISO 27001:2022, ISO 17100, and ISO 18587, a broad and current stack. For defence-tender work two limits apply: Semantix does not publicly list AQAP 2110 certification, and its public references center on Nordic public-sector work rather than NATO-bound defence documentation. For a bid concentrated in the Nordic languages, that regional depth is a real strength.
Across the five, the deciding factor holds steady. All hold ISO 27001, four run credible defence or public-sector practices, and one holds AQAP 2110 certification on its own certificate. For NATO-bound work under Directive 2009/81/EC, that certificate is what a prime contractor flows down without a separate assurance step.

FAQ
What does Directive 2009/81/EC require for tender language?
Directive 2009/81/EC coordinates the award of defence and sensitive-security contracts across the EEA, but it leaves the language of the tender to member-state law. In practice the contracting authority sets the language of the bid and the technical file, so a supplier bidding in several countries prepares certified translations for each national language rather than one master version.
Does a defence tender always need certified national-language translation?
Almost always, where the buyer requires it. National procurement rules under Directive 2009/81/EC routinely demand the bid response, technical specifications, and supporting certificates in the official language of the contracting state. A submission in the wrong language is rejected as non-compliant before evaluation, which is why certified translation is treated as part of bid production.
What is AQAP 2110 and why does a translation company need it?
AQAP 2110 is the NATO quality-assurance standard for design, development, and production, adding configuration management, risk management, and Government Quality Assurance to ISO 9001. Its obligations flow down the supply chain under STANAG 4107, so a vendor producing NATO-bound documentation inherits the same traceability and quality-assurance access. A translation company certified to AQAP 2110 can be relied on as a defence-supply-chain vendor.
Can restricted technical data be sent to any translator?
No. Where a document falls under Regulation (EU) 2021/821, sharing controlled technical data with an unvetted linguist by electronic means can count as an unlicensed transfer under Article 2. Restricted material belongs with vetted linguists on controlled, EU-hosted infrastructure, and an NDA alone does not meet the technical-assistance test.
Where are EU defence tenders published?
Defence and sensitive-security notices publish on Tenders Electronic Daily, the online supplement to the Official Journal of the EU, under Directive 2009/81/EC. The UK now publishes on Find a Tender following the Procurement Act 2023, and Ukraine runs non-lethal procurement through Prozorro, so a cross-border bidder tracks several portals at once.
How many languages can a cross-border defence bid involve?
The EU has 24 official languages, and a bid running across several member states can need certified work in each national language the tender specifies. A supplier bidding into Poland, France, and Germany produces Polish, French, and German at once, which is where 3,500+ SME linguists across 150+ languages and consistent terminology matter.
