Do you trust that foreign-owned technology used in your nation's critical infrastructure is secure?
Critical infrastructure in Europe and the UK faces potential security risks due to significant reliance on Chinese equipment suppliers. A report from October 2026 revealed that nations lack unified standards for identifying high-risk technology vendors.
Why it matters
The absence of a cohesive policy among European nations regarding ICT equipment has created inconsistent security protocols across the continent. This fragmentation leaves sensitive communication and research networks exposed to potential foreign vulnerabilities.
Germany relies on Chinese suppliers for nearly 60% of its 5G radio access network components. Meanwhile, Spain awarded a €12m contract to Huawei for OceanStor cloud storage systems that have housed judicial wiretap records.
The players
Huawei
This Chinese multinational technology corporation is a major global supplier of telecommunications equipment and cloud storage infrastructure.
ZTE
This Chinese technology company specializes in telecommunications hardware and networking equipment for global markets.
MI5
This British intelligence agency is responsible for protecting the United Kingdom against threats to national security.
Rusi
This independent research institute provides analysis and policy recommendations on international security and defense issues.
The details
Nations currently employ a patchwork approach to assessing risk, often without basic information about the specific equipment integrated into their networks. In some instances, this has led to sensitive data, such as judicial wiretap recordings, being stored on Chinese-made servers.
Timeline
In 2025, US lawmakers raised concerns regarding Spanish Huawei data storage.
Rusi published a report on Chinese tech risk in October 2026.
The Tech Race
The reliance on foreign suppliers like Huawei and ZTE marks a critical tension point as nations modernize their digital foundations. This report follows the precedent set by the Rusi report on Chinese tech risk by illustrating how legacy integration complicates efforts to secure 5G networks.
Users may face evolving digital security requirements as governments potentially phase out or audit existing infrastructure components. These changes could influence the availability and cost of next-generation connectivity services as providers adjust to new compliance standards.
The takeaway
The lack of standardized security assessments across European countries leaves critical data systems potentially vulnerable to foreign intervention. Readers should remain aware that national security policies regarding digital hardware are becoming increasingly stringent as infrastructure risks are identified.
