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

3 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 Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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

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

MTU Aero Engines holds a strong market position as a leading German engine manufacturer with a broad global network of subsidiaries and service centers. Their business model focuses on engine manufacturing and lifecycle services, catering to commercial and military aviation sectors. The company maintains active investor relations and compliance transparency, indicating a well-established corporate governance structure. The website content and navigation are designed to support multiple stakeholder groups including customers, investors, and job seekers, highlighting growth and innovation initiatives such as the Flying Fuel Cell project. Partnerships and subsidiaries are clearly identified, supporting a diversified and resilient business ecosystem.

Security posture

The website exhibits a solid security posture with HTTPS enabled and secure cookie handling. The presence of a cookie consent mechanism aligns with GDPR requirements, and no sensitive data exposure or vulnerable libraries were detected in the HTML content. However, the absence of a dedicated security policy page and incident response contact details suggests room for improvement in transparency and readiness. Security headers are not explicitly visible in the provided data, and recommendations include implementing standard HTTP security headers and publishing clear security policies. Overall, the security maturity is good but could be enhanced to meet best practices fully.

Recommendations

  1. Publish a dedicated security policy page outlining security frameworks and practices.
  2. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  3. Implement and verify HTTP security headers like Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Regularly audit and update third-party scripts and libraries to mitigate vulnerabilities.
  5. Enhance visibility of data protection officer contact information to improve GDPR compliance transparency.

Technical notes

Notes

The website is built on TYPO3 CMS, a robust and widely used content management system, indicating a stable and scalable infrastructure. It uses modern JavaScript libraries such as jQuery, Fancybox, and Swiper for interactive UI components. Analytics are handled via Piwik/Matomo, supporting privacy-conscious tracking. The site is mobile optimized with responsive design and accessibility features like skip links and ARIA labels. Performance is moderate, with compressed CSS and JS assets, though some scripts are deferred or loaded asynchronously. The technical setup supports a professional user experience but could benefit from enhanced security headers and performance tuning for faster load times.
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.
