This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

8 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

BIOTRONIK operates in the healthcare industry with a focus on cardiac rhythm management, vascular intervention, electrophysiology, and radiation protection. Their business model centers on manufacturing and distributing advanced medical devices and providing related professional services including clinical studies and remote patient monitoring. The company targets a global audience including patients and medical professionals. Their partnerships with recruitment and monitoring service providers enhance operational capabilities. The company’s long history since 1963 and consistent domain registration reinforce market trust. The website content and structure support strong brand positioning and customer engagement.

Security posture

The website’s security posture is weak due to the lack of HTTPS and SSL/TLS encryption, which is a critical vulnerability that undermines user data protection and trust. While some security headers like HSTS and X-Content-Type-Options are present, the absence of a valid certificate and modern TLS protocols significantly lowers the security score. No incident response or vulnerability disclosure policies are publicly available, which could hinder timely handling of security issues. The site uses consent management tools indicating awareness of privacy regulations, but urgent remediation of transport layer security is necessary to protect users and comply with best practices.

Recommendations

  1. Implement HTTPS with a valid SSL/TLS certificate immediately to secure all user communications.
  2. Enable modern TLS protocols (TLS 1.2 or 1.3) and configure strong cipher suites to enhance encryption strength.
  3. Add and regularly update security headers such as Content-Security-Policy and Referrer-Policy to mitigate common web attacks.
  4. Publish a clear security policy and incident response contact information to improve transparency and readiness.
  5. Continue to maintain and improve privacy compliance with visible cookie consent and data protection officer contact details.

Technical notes

Notes

The website is powered by Drupal 10 CMS, indicating a modern and maintainable platform. It uses JavaScript libraries and integrates Usercentrics for consent management and Google Tag Manager for analytics. Hosting is supported by Versatel DNS and Varnish caching servers located in Frankfurt and Helsinki, suggesting a robust infrastructure. The site is mobile optimized and accessible with good SEO practices. However, the lack of HTTPS severely impacts the technical security posture. Performance data is missing, but the use of caching and CDN-like services suggests potential for good load times. Technical debt appears low, but urgent security upgrades are required.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
