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. 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';…
  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.

    • 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

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

Sievert operates in the manufacturing and transportation sectors, providing premium construction materials and logistics services. The company targets B2B customers in Germany, Europe, and China, leveraging a large workforce and multiple locations. Their business model focuses on delivering high-quality products and integrated logistics solutions, supported by consulting and technical documentation services. The company maintains a strong brand with consistent messaging and active social media engagement. Growth is supported by sustainability initiatives and a comprehensive career and training academy. The website supports these business goals with detailed product and service information, career opportunities, and customer support tools.

Security posture

The website demonstrates a moderate to good security maturity level with HTTPS enabled and a cookie consent mechanism that complies with GDPR. However, there is no visible security policy or incident response contact information, and no security.txt file is published. Security headers such as Content-Security-Policy and X-Frame-Options are not detected, which could improve protection against common web attacks. No vulnerabilities or exposed sensitive data were found in the HTML content. The absence of explicit incident response channels and security certifications suggests room for improvement in security transparency and readiness.

Recommendations

  1. Implement standard security headers (CSP, X-Frame-Options, X-Content-Type-Options) to enhance protection.
  2. Publish a dedicated security policy page and provide incident response contact information.
  3. Enable DNSSEC for the domain to improve DNS security.
  4. Consider adding a security.txt file to facilitate vulnerability disclosures.
  5. Regularly audit third-party scripts and dependencies for vulnerabilities and update them accordingly.

Technical notes

Notes

The website uses the Neos CMS platform built on the Flow PHP framework, indicating a modern and flexible content management system. The site loads multiple responsive images and uses lazy loading for performance optimization. Google Tag Manager is used for analytics and marketing tracking. The site is mobile-optimized with responsive design and accessible navigation. Performance is moderate with room for improvement in loading speed and accessibility features. The domain is registered with a reputable registrar but is relatively new, which may reflect a recent rebranding or new international presence. Overall, the technical infrastructure supports a professional and scalable web presence.
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.
