Introduction
The average cost per cyber breach in 2025 was $7.42 million globally. The healthcare industry was one of the industries that suffered the most during data breaches. In the case of medical device manufacturers, this is because your product can be subjected to regulatory and financial risks. To counter this menace, the EU has introduced cybersecurity as a compulsory provision in the CE marking, including the CE Mark Cybersecurity Assessment. The authorities require the medical equipment company to implement MDR cybersecurity testing and vulnerability scanning, penetration testing, fuzz testing, and many others.
To work efficiently in the European market, manufacturers must:
Know the required testing, have a security by design structure that meets the audits of the Notified Body under EU MDR compliance. They must have comprehensive technical documentation throughout the lifecycle of the device.
What is the CE Mark Cybersecurity Assessment?
A CE Mark Cybersecurity Assessment is an obligatory procedure that allows manufacturers to prove their compliance with EU safety, health, and environmental regulations of their digital products. Products cannot be placed on the EU market without meeting applicable CE marking requirements, including cybersecurity-related obligations where relevant. The rules state that to achieve CE marking, it is a prerequisite to maintain cybersecurity.
- Radio Equipment Directive (RED 2014/53/EU): The Radio Equipment Directive (RED) introduces cybersecurity requirements for certain connected devices, with enforced as of August 2025 under Articles 3.3 (d), (e), and (f), depending on device category. The act mandates network integrity, personal data security, and avoidance of fraud or abuse.
- The Cyber Resilience Act (CRA): The upcoming Cyber Resilience Act (CRA) will introduce mandatory cybersecurity requirements for products with digital elements and is expected to impact CE marking in the coming years.
- Sector regulation: Medical devices must comply with cybersecurity regulations such as the EU Medical Device Regulation (MDR) guidelines to prevent unauthorized access and safeguard the sensitive data of patients.
Common Cybersecurity Testing Approaches Used for MDR Compliance
Companies producing medical devices in the European Union must be in compliance with the EU medical device security requirements. To meet the General Safety and Performance Requirement, the manufacturers may go through these 4 types of cybersecurity tests:
1. Vulnerability Scanning
This is technically the minimum of cybersecurity testing in EU MDR compliance. To detect known vulnerabilities, manufacturers must methodically scan software in scanning devices, third-party components, and even the Software of Unknown Provenance (SOUP).
Vulnerability scanning identifies known issues in systems and components, while SAST analyzes source code for security weaknesses during development. Software Composition Analysis also discovers risks in the open-source dependencies and supports SBOM requirements, and Dynamic Application Security Testing (DAST) that tests running applications to identify vulnerabilities such as injection vulnerabilities or cross-site scripting.
2. Fuzz Testing (Robustness Testing)
It involves giving invalid, unpredictable, or random data to the communication interfaces of the device in order to determine whether it can result in a failure or an insecure state. The chief objective of the fuzz testing is to demonstrate that the device is resistant to malformed input types of cyberattacks. The team performs the testing in all the outside interfaces such as Bluetooth Low Energy (BLE), Wi-Fi, USB ports, and proprietary serial ports.
3. Penetration Testing
Medical devices, connected mobile applications, and cloud backends are tested in penetration testing. Security experts perform a simulated real-world attack to identify exploitable weaknesses and test the safety of medical machines as stipulated by the EU MDR.
The key objective of the penetration testing is to demonstrate that the cyberattackers will not be able to circumvent security controls. In the case of more risky devices (Class IIa and higher), independent third parties will be required by the manufacturers to conduct the penetration testing.
4. Security Feature Testing
Such testing confirms that the particular security controls adopted by the manufacturers to minimize risks actually perform practically. It is concerned with proving every countermeasure as to its intent. It encompasses all Security Claims in the Technical File, such as user access controls (RBAC), secure boot sequences, and data at rest and in transit.
As an example, say you have defined encryption in your risk management plan to avoid data theft; in this case, this testing will give evidence that the encryption is working to protect data as expected.
5. Source Code Review/Analysis
It is the White Box assessment of MDR 2017/745. It analyses the software source code of the device to discover security vulnerabilities, bugs, or lack of adherence to secure coding guidelines (e.g., MISRA C, CERT C, or OWASP).
At the time that vulnerability assessment indicates vulnerabilities, Source Code Review/Analysis identifies the so-called hidden flaws of the automated scanners. It dwells upon high-risk modules, such as cryptographic implementations, authentication logic, memory management (to eliminate buffer overflows), and data-handling routines in support of Patient Identifiable Information (PII).

How Do Notified Bodies Assess Medical Security?
Notified Bodies (NBs) evaluate device security through an audit. NBs focuses on the “Security by Design” principle:
1. Lifecycle Traceability:
The Notified Bodies ensure that they address cybersecurity throughout the device’s entire lifecycle. It covers risk management according to ISO 14971, development according to IEC 62304 and EN 81001-5-1, and finally post-market activities.

2. Evidence:
The relevant authorities require the manufacturer to produce detailed reports on cybersecurity tests that have been performed. These include vulnerability scanning, source code review, fuzz testing, Penetration Testing, and security feature verification. In addition to this, third-party penetration testing is also required for high-risk devices to ensure unbiased results.
3. State of the Art (SOTA):
The Notified Bodies check to ensure that they have taken security measures according to the state of the art. They use guidelines such as MDCG 2019-16 and security protocols such as TLS 1.3.
Required Documentation for the CE Cybersecurity Assessment
Manufacturers of medical devices need to show the cybersecurity practices throughout the product lifecycle. They are also in line with CE mark cybersecurity requirements and broader EU medical device security compliance expectations.
1. Cybersecurity Risk Management Plan
This is the foundation of your cybersecurity assessment. It must align with ISO 14971 and AAMI TIR57. You need to provide a Formal Threat Model that visually maps your device’s attack surface and entry points.
2. Design Specifications & SBOM
To meet CE mark cybersecurity requirements, you must provide a Secure Architecture Design that includes details of encryption layers and authentication checkpoints. Software Bill of Materials (SBOM), along with Security Requirements Specification (SRS), is critical to support compliance with EU medical device security compliance frameworks.
3. Verification & Validation (V&V) Evidence
Provide evidence from cybersecurity testing in accordance with MDR cybersecurity testing expectations. This includes vulnerability assessment reports (SAST/DAST/SCA), code review summaries, healthcare penetration testing (for connected devices), fuzz testing results, and verification of implemented security features.
4. Lifecycle & Post-Market Plans
A cybersecurity assessment of medical devices requires proof that security continues after the sale. Manufacturers need to document a Post-Market Surveillance (PMS) Plan to monitor new “Zero-Day” threats and a Vulnerability Disclosure Policy (VDP) for external reporting. The manufacturer also needs to secure update mechanisms, including digitally signed updates and validation before deployment
Pro Tip
