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

2 findings 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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

  2. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

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.

Business context

Business profile

SYNLAB AG operates in the healthcare diagnostics sector with a strong market position as a European leader. Its business model focuses on providing diagnostic services to a broad audience including patients, medical professionals, hospitals, and governments. The company demonstrates transparency through regular financial and governance disclosures and maintains active communication channels. The presence of related domains for investor information and corporate mission indicates a well-structured corporate ecosystem. The use of professional CMS and analytics tools supports digital maturity. Growth indicators include recent news on acquisitions and leadership appointments. The company’s partnership ecosystem includes domains like synlab.com, reinforcing brand consistency.

Security posture

The website exhibits a solid security posture with HTTPS enabled and cookie consent implemented. No security headers were explicitly detected in the provided data, suggesting room for improvement. No exposed sensitive data or vulnerable libraries were found. However, the absence of a public security policy or incident response contact reduces transparency in security governance. The site uses Google Analytics with user consent, indicating privacy awareness. Overall, the security maturity is good but could be enhanced by publishing security policies, incident response procedures, and implementing additional HTTP security headers.

Recommendations

  1. Publish a dedicated security policy page outlining security governance and controls.
  2. Provide clear incident response contact information (e.g., security@ or abuse@ email).
  3. Implement and publish a vulnerability disclosure policy or security.txt file.
  4. Enhance HTTP security headers such as Content-Security-Policy, X-Frame-Options, and HSTS.
  5. Regularly audit third-party scripts and analytics tools for security and privacy compliance.

Technical notes

Notes

The website is built on TYPO3 CMS using the Bootstrap package, indicating a modern and maintainable infrastructure. It employs JavaScript and CSS for interactive and responsive design, with good mobile optimization and accessibility features. Google Analytics is integrated for user behavior tracking with consent. Performance is moderate, with compressed assets and responsive images. No hosting provider details were found. The site demonstrates good SEO practices with meta tags and canonical links. Technical risks are minimal but could be reduced by improving security headers and ensuring continuous monitoring of third-party dependencies.
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.
