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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  2. 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 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';…

  3. 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

The company targets construction professionals, civil engineers, and infrastructure developers with a B2B manufacturing business model. Their product portfolio focuses on drainage systems for industrial, logistics, and urban applications. The website demonstrates strong branding consistency and trust signals such as detailed references and social media presence. While no direct contact emails or phone numbers were found in the provided content, the presence of privacy and cookie policies indicates regulatory compliance. The company appears medium-sized and focused on manufacturing and transportation sectors within Germany.

Security posture

The website enforces HTTPS and implements a cookie consent mechanism via Klaro. No exposed sensitive data or vulnerable libraries were detected. However, security headers like Content-Security-Policy and X-Frame-Options are not explicitly present in the HTML content. There is no visible security policy or incident response contact information, which could be improved to enhance transparency and readiness. No security.txt or vulnerability disclosure page was found. Overall, the security posture is good but could benefit from additional security headers and published policies.

Recommendations

  1. Add explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy page and provide incident response contact information to improve transparency and trust.
  3. Implement and publish a security.txt file to facilitate responsible vulnerability disclosure.
  4. Include clear company contact emails and phone numbers on the website to improve user trust and communication.
  5. Regularly audit third-party scripts and tracking tools to ensure no vulnerable or privacy-invasive components are used.

Technical notes

Notes

The website uses TYPO3 CMS with Bootstrap for responsive design and jQuery for frontend scripting. Google Tag Manager is used for analytics and marketing tracking. The site is mobile-optimized with good accessibility features such as skip links and ARIA labels. Performance is moderate, with compressed CSS and JS assets. The cookie consent is managed by Klaro, supporting GDPR compliance. No major technical debt or outdated libraries were detected. Hosting provider details are not explicitly available. Overall, the technical infrastructure is modern and well-implemented.
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.
