NIS2 and GDPR posture

Not assessed

Both readouts depend on the site's pages, which could not be loaded in this scan.

Priority findings

1 finding rated critical or high. Fix these first.

  1. 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

  • Security headers: did not complete in this scan.
  • GDPR outside view: did not complete in this scan.
  • 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

The company maintains a professional digital presence using the Liferay CMS platform, integrating marketing and analytics tools such as HubSpot. The website structure supports multiple languages and provides comprehensive corporate information, including management, history, sustainability, and career opportunities. The domain registration data aligns with the company's German roots and business claims, supporting legitimacy. The company appears to have a well-established partnership ecosystem and a clear focus on compliance and corporate responsibility.

Security posture

The website currently lacks a valid SSL certificate, serving content over HTTP only, which is a critical security vulnerability. While some security headers like X-Content-Type-Options, X-Frame-Options, and X-XSS-Protection are present, the absence of HTTPS and HSTS significantly weakens the security posture. No incident response or vulnerability disclosure information is publicly available, and no security.txt file is detected. Cookies are set with HttpOnly flags, and privacy policies are in place, indicating some attention to data protection. Overall, the security maturity is low and requires urgent improvements to protect user data and trust.

Recommendations

  1. Install and maintain a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Enable HTTP Strict Transport Security (HSTS) with includeSubDomains and preload options.
  3. Update SSL/TLS configuration to support modern protocols (TLS 1.2 and 1.3) and strong cipher suites.
  4. Publish a security.txt file and provide clear incident response contact information.
  5. Enhance privacy compliance by documenting data retention policies and improving cookie consent transparency.
Technical notes

Notes

The website is built on Liferay Digital Experience Platform 7.1.10 GA1, utilizing technologies such as jQuery, Bootstrap, and Clay CSS/JS. The site integrates HubSpot for marketing and analytics. DNS records indicate hosting and mail services via Retarus and 123ns.de. Performance metrics are not available, but the site shows basic mobile optimization and accessibility features. The lack of HTTPS and modern TLS protocols is a significant technical debt. The site uses multiple portlets and nested portlets, indicating a modular architecture but potentially increasing complexity. SEO and accessibility are basic but functional.
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.
