This post introduces Wise Company’s strategy for addressing European CE medical device cybersecurity regulatory compliance based on MDR, IEC 81001-5-1, and ISO 14971.
European (CE) Medical Device Cybersecurity
A Practical Guide Based on MDR, IEC 81001-5-1, and ISO 14971

1. Security Is Not “Technology” – It Is a Regulatory Requirement

Under MDR Annex I GSPR 17.1-17.2, medical devices incorporating electronic and programmable systems must ensure reliability and performance in accordance with their intended purpose.
In addition, software must be developed according to the state of the art, following principles of risk management, verification, and information security.
MDR’s Cybersecurity Perspective
MDR treats cybersecurity as an essential patient safety requirement. Products without adequate security are considered unsafe.
Therefore, cybersecurity is a key evaluation item in the CE conformity assessment process.
2. Security Starts at the Design Stage


Manufacturer Security Activity Requirements
Document Security Functional Requirements
Establish activities to document security functional requirements covering installation, operation, maintenance, and end-of-life
Review Security Requirements Consistency
Review whether security requirements are consistent with product requirements and risk controls, clearly defined, and expressed in a way that allows test criteria to be established
IEC 81001-5-1:2021 Clauses 5.2.1-5.2.2 require manufacturers to document security requirements during the design input phase and to ensure they are consistent with risk controls and verifiable.
This means that security is not a post-development checklist item, but a regulatory requirement incorporated from the design stage.
3. Security Risks Are Managed as Safety Risks


Risk Management Requirements
Identify and Analyze Hazards Throughout the Lifecycle
Manufacturers shall identify and analyze all hazards throughout the entire lifecycle of the medical device, including harms resulting from software, system, or data security failures.
Assess CIA Loss Impact
For each identified asset, the impact of any loss of confidentiality, integrity, or availability (CIA) on safety, effectiveness, and system or data security shall be assessed.
Key Standard Requirements
- ISO 14971:2019 Clause 4.1 – Requires management of all risks throughout the device lifecycle, including those caused by software and data security failures
- AAMI TIR57:2016 Clause 4.3.4 – Requires assessment of how CIA losses affect safety and effectiveness
4. A Security Framework Proven by Documentation



Technical Documentation Requirements
MDR Annex II – Security Requirements and Verification Results
Technical documentation must include security requirements and verification results demonstrating compliance with Annex I (GSPR)
MDCG 2019-16 Rev.1 Section 4.1 – Solution Justification and Verification
Justification, verification, and results for solutions addressing security risks must be documented
In short, security is not proven by implementation alone – it is proven through documentation for regulatory approval.
European CE Cybersecurity Key Summary
| Key Principle | Main Content | Related Standards |
|---|---|---|
| Regulatory Requirement | Security is a patient safety requirement Key item in CE conformity assessment |
MDR Annex I GSPR 17.1-17.2 |
| Design Integration | Document security requirements from design input phase Ensure consistency with risk controls |
IEC 81001-5-1:2021 Clauses 5.2.1-5.2.2 |
| Risk Management | Manage security risks as safety risks Assess CIA loss impact on safety |
ISO 14971:2019 AAMI TIR57:2016 |
| Documentation | Document security requirements and verification Document solution justification and verification |

Conclusion
European CE medical device cybersecurity is not merely a technical implementation, but a regulatory requirement.
MDR, IEC 81001-5-1, and ISO 14971 define security as a core element of patient safety and require a systematic approach from design stage through documentation.
Wise Company Inc. supports manufacturers in achieving CE conformity through cybersecurity strategies based on these international standards.
