May 19 (Asia Today) — South Korea’s fast-growing defense industry is confronting a major new obstacle in the U.S. market as the Pentagon fully implements strict cybersecurity certification requirements across its global supply chain.
The U.S. Department of Defense has begun enforcing the final version of the Cybersecurity Maturity Model Certification, or CMMC, program, requiring all companies participating in U.S. defense contracts to meet specific cybersecurity standards.
Industry officials warn that Korean defense firms unable to obtain certification could be excluded not only from exports to the United States but also from ship maintenance, repair and overhaul projects and future joint weapons development programs.
The certification system applies not only to primary contractors but also to subcontractors supplying parts and components.
Even companies with advanced technology and competitive pricing can be blocked from bidding if they fail to meet required cybersecurity levels.
For many South Korean defense firms, the most critical threshold is CMMC Level 2, which is required for handling Controlled Unclassified Information, or CUI, tied to U.S. military programs.
The requirement is considered especially important for South Korea’s ambitions to participate in U.S. Navy ship maintenance and repair projects, as well as broader bilateral defense cooperation initiatives.
Defense analysts say the new rules are becoming a de facto trade barrier across Western defense markets.
«Losing access to the U.S. market effectively means being pushed out of the global defense supply chain,» one industry expert said.
Defense Acquisition Program Administration has launched information sessions and consulting support programs in response to growing industry concerns.
The agency is working with regional defense innovation clusters, the Korea Defense Industry Association and the Defense Agency for Technology and Quality to help companies prepare for certification.
But smaller suppliers say the burden remains overwhelming.
Industry estimates suggest that achieving Level 2 certification can cost companies from hundreds of thousands to several million dollars due to infrastructure upgrades, consulting fees and final audits. Preparation alone can take more than a year.
Large defense contractors have already formed dedicated task forces, but many second- and third-tier suppliers lack both funding and cybersecurity specialists.
Because the CMMC system requires certification across the entire supply chain, failure by even a single subcontractor could jeopardize broader export opportunities involving larger Korean defense firms.
Additional complications stem from differences between U.S. and South Korean encryption standards.
One key CMMC requirement involves use of cryptographic modules certified under U.S. National Institute of Standards and Technology guidelines known as FIPS standards.
Many South Korean defense companies, however, rely on domestic encryption systems validated under the country’s K-CMVP framework overseen by intelligence and defense authorities.
Industry experts are calling for government-level negotiations between Seoul and Washington to seek mutual recognition or equivalency between Korean and U.S. encryption standards.
Some officials argue such talks could be linked to ongoing negotiations over a Reciprocal Defense Procurement Agreement between the two allies.
Concerns are also growing over South Korea’s lack of domestically accredited third-party CMMC assessment organizations, forcing companies to rely on U.S.-based auditors and raising concerns about defense technology exposure.
Analysts say South Korea’s defense industry must now treat cybersecurity as strategically important as weapons performance itself if it hopes to become a top-tier global arms exporter.
