0–100, higher is better. How it is calculated

BALCKE-DÜRR GmbH is an established German company specializing in the supply of heat exchangers and reactors, primarily serving industrial clients in the energy and manufacturing sectors. The company has a long-standing presence since 1997, supported by a professional and well-structured website that targets B2B customers. The website is built on WordPress using the Enfold theme and incorporates SEO best practices via the Yoast SEO plugin, indicating a moderate level of digital maturity. From a security perspective, the website employs HTTPS and has domain transfer protections in place, but lacks advanced DNS security features such as DNSSEC and does not exhibit explicit security headers. There is a cookie consent mechanism implemented, reflecting some privacy compliance efforts, though no formal privacy policy or terms of service were detected. Contact information is not explicitly presented in the analyzed content, which may impact user trust and compliance. Overall, the website demonstrates a solid business credibility and technical foundation but would benefit from enhanced security practices, clearer privacy documentation, and more transparent contact details to improve trust and compliance. Strategic recommendations include enabling DNSSEC, publishing comprehensive privacy and security policies, and implementing security headers to strengthen the security posture.

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

5 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  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

BALCKE-DÜRR GmbH operates in the energy sector, focusing on manufacturing and supplying heat exchangers and reactors. The company targets industrial clients requiring specialized equipment, positioning itself as a reliable supplier with over two decades of market presence. The business model is B2B, emphasizing quality and technical expertise. The website content and domain age support a stable market position, though the lack of visible contact details and formal policies may limit customer engagement and trust. The company appears to maintain a focused product portfolio without evident diversification or subsidiaries. Digital marketing efforts include SEO optimization but lack advanced analytics or advertising integrations.

Security posture

The website's security posture is moderate. HTTPS is enforced, and the domain status clientTransferProhibited prevents unauthorized domain transfers. However, the absence of DNSSEC and security headers such as Content-Security-Policy or X-Frame-Options reduces resilience against certain attacks. No vulnerability disclosure or incident response information is provided, limiting transparency. The cookie consent mechanism is a positive privacy feature, but the lack of a privacy policy and terms of service indicates compliance gaps. No contact channels for security incidents (e.g., security@ or abuse@ emails) were found. Overall, the security maturity is basic with room for improvement to meet modern standards and regulatory requirements.

Recommendations

  1. Enable DNSSEC to enhance domain name system security and prevent DNS spoofing.
  2. Implement and publish comprehensive privacy policy and terms of service to improve legal compliance and user trust.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to mitigate common web vulnerabilities.
  4. Provide explicit contact information including security incident response contacts to improve transparency and readiness.
  5. Consider publishing a vulnerability disclosure policy or security.txt file to encourage responsible reporting and improve security culture.

Technical notes

Notes

The website is built on WordPress with the Enfold theme and uses the Yoast SEO plugin, indicating a modern CMS-based infrastructure optimized for SEO. The hosting registrar is InterNetX GmbH, a reputable provider. Performance is moderate with good mobile optimization and basic accessibility features. The site uses standard web technologies including HTML5, CSS, and JavaScript. No advanced analytics or third-party marketing tools were detected, suggesting limited tracking and data collection. The absence of DNSSEC and security headers represents technical debt in security. Overall, the technical implementation supports business needs but could benefit from modernization in security and privacy features.
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.
