ISO Certification for Defense Contractors: ISO 9001, ISO 27001, CMMC Readiness, and ISO 18788
ISO certification for defense contractors gives primes and agencies evidence they can check. It shows that quality, information security, and supply chain risk are controlled before a contract is signed. Accredify Global certifies defense management systems, including ISO 9001, ISO 27001, ISO 28000, and ISO 18788. We also assess readiness for AS9100, AQAP 2110, and CMMC. You get a tailored proposal after a free scoping review.
What ISO Certification for Defense Covers
ISO certification for defense contractors is an independent audit of how a supplier manages quality, information security, supply chain security, and ethics against ISO standards. Most suppliers start with ISO 9001 and ISO 27001. Those making aerospace or NATO items usually add AS9100 or AQAP 2110. A successful ISO audit leads to a certificate valid for three years.
Defense also has requirements that no ISO certificate meets on its own. CMMC and NIST SP 800-171 protect controlled unclassified information in US contracts. ITAR registration is filed with the State Department. NATO quality requirements are verified by national government quality assurance representatives.
Accredify Global is an accredited certification body. We certify the ISO systems underneath these programs and assess your readiness for the rest, so each customer audit starts from evidence you already hold.
Defense Requirements in 2026: ISO 9001:2026, CMMC, and AS9100
ISO 9001:2026 was published on 16 September 2026. Global ACI, which took over the work of the IAF, set the transition rules the same day. New certifications must use the 2026 edition from 31 March 2028, and 2015 certificates must transition by 30 September 2029. AS9100 and AQAP 2110 both build on ISO 9001, so their updates will follow.
CMMC Phase 2 was suspended on 13 July 2026. Phase 1 has applied since 10 November 2025, so Level 1 and Level 2 self-assessments and SPRS scores are still required. Phase 2 would have added Level 2 certifications by C3PAOs from 10 November 2026. A reform task force is reviewing the program, and no new date has been set. DFARS 252.204-7012 and NIST SP 800-171 obligations are unchanged.
AS9100D is still the current aerospace and defense standard. The IAQG is preparing its replacement, IA9100, to align with ISO 9001:2026. ISO 37001, the anti-bribery standard, was also revised in 2025.

ISO Certification for Defense: Standards and What We Provide
Quality and information security first, then the schemes and standards your customers name.
| Standard or scheme | What it covers | Who usually needs it | What Accredify Global provides |
|---|---|---|---|
| ISO 9001 | Quality management | Every supplier, as a first step | Certification |
| AS9100 | Aerospace and defense quality | Aircraft, missile, and space suppliers | Gap assessment (IAQG-recognized bodies certify) |
| AQAP 2110 | NATO quality assurance for design and production | Suppliers on NATO-country contracts | Readiness (verified by government quality assurance) |
| ISO 27001 | Information security | Anyone holding technical or customer data | Certification |
| NIST SP 800-171 / CMMC | Protection of controlled unclassified information | US defense contractors | Readiness (we are not a C3PAO) |
| ISO 28000 | Supply chain security | Logistics partners and depots | Certification |
| ISO 22301 | Business continuity | Sole-source and critical suppliers | Certification |
| ISO 18788 | Private security operations | Security and protective service providers | Certification |
| ISO 37001 | Anti-bribery management | Contractors working with governments | Certification |
| ISO 45001 | Occupational health and safety | Plants, ranges, and field teams | Certification |
| ISO 14001 | Environmental management | Manufacturers and depots | Certification |
ISO 37001 is within our UAF accreditation scope. For the other standards listed, your proposal names the certification body that will issue your certificate.
ISO 27001 vs NIST SP 800-171 and CMMC: How They Fit
Defense suppliers often need both. They overlap, but neither replaces the other.
| Topic | ISO 27001 | NIST SP 800-171 / CMMC |
|---|---|---|
| Purpose | A management system for all information risks | Fixed controls for controlled unclassified information |
| Scope | You define it, often the whole business | Systems that store, process, or send CUI |
| Controls | Chosen by risk from Annex A | 110 required controls in SP 800-171 Rev. 2 |
| Who checks | An accredited certification body | Self-assessment, or a C3PAO when required |
| Recognition | Worldwide, across all sectors | US Department of Defense contracts |
| Result | Certificate valid for three years | SPRS score and affirmation |
A practical route is to build one information security system that meets both. Map each NIST control to an ISO 27001 Annex A control, then keep one set of evidence. When the CMMC review ends and the next phase is set, you will not need to start again.

| Pricing | Ask for audit man-days in writing. Ours come in a tailored proposal. |
FAQ: ISO Certification for Defense
Straight answers on CMMC, AS9100, AQAP 2110, ITAR, cost, and timeline.
Which ISO certification do defense contractors need?
Most start with ISO 9001 for quality and ISO 27001 for information security. Aerospace and defense manufacturers are often asked for AS9100, NATO suppliers for AQAP 2110, and logistics partners for ISO 28000.
Is ISO 9001 enough for defense contracts?
For many sub-tier and service suppliers, yes. Prime contractors and defense agencies often add AS9100, AQAP 2110 or customer-specific clauses for flight-critical or mission-critical items. ISO 9001 is the base for all of them.
Does Accredify Global perform CMMC assessments?
No. Accredify Global is not a CMMC Third-Party Assessment Organization (C3PAO). We run NIST SP 800-171 and CMMC readiness assessments and certify ISO 27001, which covers much of the same ground.
What is the status of CMMC in 2026?
Phase 1 has applied since 10 November 2025, so self-assessments and SPRS scores are required in new contracts. On 13 July 2026 the Department suspended Phase 2, which would have added C3PAO certifications, and started a review. DFARS 252.204-7012 and NIST SP 800-171 still apply.
Does ISO 27001 replace CMMC or NIST SP 800-171?
No. ISO 27001 does not satisfy DFARS or CMMC requirements on its own. The two overlap heavily, so a well-run ISO 27001 system makes the NIST SP 800-171 controls much easier to evidence.
What is AQAP 2110?
AQAP 2110 is the NATO quality assurance standard for design, development and production. Edition D, from June 2016, includes all of ISO 9001:2015 and adds NATO requirements, including access for government quality assurance representatives.
Can Accredify Global certify AS9100?
No. AS9100 certificates can only be issued by certification bodies recognized under the IAQG scheme. We run an AS9100 gap assessment and certify the ISO 9001 system it builds on.
Is ITAR registration a certification?
No. ITAR registration is filed with the US State Department's Directorate of Defense Trade Controls. No ISO certificate replaces it, but ISO 27001 and ISO 9001 help you control export-controlled data and parts.
What is ISO 18788?
ISO 18788 is the management system standard for private security operations. It covers use of force, human rights, weapons management and incident reporting for security providers working for governments and defense clients.
Do defense logistics companies need ISO 28000?
Often. ISO 28000 covers security management in the supply chain, including cargo, facilities and people. It is useful for freight forwarders, warehouses and carriers moving defense materiel.
Do defense contractors need ISO 37001?
Increasingly. Defense procurement carries high bribery risk, and ISO 37001 shows you run an anti-bribery system. The 2025 edition replaced the 2016 version.
How long does ISO certification take for a defense company?
Most companies with a working management system certify in 6 to 12 weeks from Stage 1 to the certificate. Several sites, several standards or a new system take longer.
How much does ISO certification cost for defense contractors?
The cost follows the audit man-days your scope needs. Headcount, sites, products and services, and the standards in scope set the man-days. A free scoping review gives you a tailored proposal.
Can auditors visit sites that hold classified work?
Audits cover the management system, not classified content. We agree access rules in advance, and the scope can exclude areas auditors may not enter. Tell us your security constraints in the scoping review.
What changes with ISO 9001:2026 for defense suppliers?
ISO 9001:2026 was published on 16 September 2026. Existing 2015 certificates must transition by 30 September 2029. AS9100 and AQAP 2110 build on ISO 9001, so plan those moves together.
Does Accredify Global write our procedures?
No. As a certification body we must stay impartial, so we audit and certify but do not write your system. Your team, or a consultant you choose, closes any gaps.
