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

BerlinerLuft.com is a professional website representing a medium-sized manufacturing company specializing in ventilation and air conditioning technology. The company offers a broad portfolio of products including industrial fans, ventilation components, air handling units, noise protection solutions, and process air systems. The website is well-designed, mobile-optimized, and provides comprehensive product and company information targeted at industrial and technical building services clients. Technically, the site is built on TYPO3 CMS and integrates Google Analytics and Tag Manager for tracking and marketing purposes. Security posture is generally good with HTTPS enforced and cookie consent implemented, though some security headers are missing and no explicit incident response or vulnerability disclosure information is found. The WHOIS data for the domain is missing or indicates the domain is not registered, which is inconsistent with the active and professional website presence, suggesting a need for verification. Overall, the site scores well on content quality and technical implementation but has moderate business credibility due to the WHOIS inconsistency.

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

11 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. Network security

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

    • Critical

      Critical Service Exposed: SMB

      Port 445 (SMB) is publicly accessible - SMB - Windows file sharing, high risk

      What to do: Immediately restrict access to SMB using firewall or VPN

      • 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
    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • 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

  3. 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"

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 · found on this site
  • 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

BerlinerLuft operates in the manufacturing sector with a focus on ventilation and air conditioning systems for industrial and technical building services markets. The company appears to have an international footprint with partner domains in multiple countries. Their business model centers on providing specialized, modular, and sustainable ventilation solutions. The website highlights references and industry solutions, indicating a strong market position and customer trust. The absence of direct contact emails or phone numbers on the site may be a deliberate choice to funnel inquiries through contact forms. The company demonstrates compliance with GDPR and cookie regulations, reflecting awareness of privacy requirements. The lack of WHOIS data raises questions about domain registration status, which should be clarified to ensure trustworthiness.

Security posture

The website uses HTTPS and has implemented a cookie consent mechanism, indicating a baseline security and privacy posture. However, no security headers such as Content-Security-Policy or X-Frame-Options were detected, which could improve protection against common web attacks. There is no visible security policy or incident response contact information, nor a security.txt file for vulnerability disclosure. No exposed sensitive data or vulnerable libraries were found in the HTML content. The integration of Google Analytics and Tag Manager is done with default consent denied initially, showing some privacy-conscious configuration. Overall, the security posture is good but could be enhanced by adding security headers and explicit security policies.

Recommendations

  1. Implement standard security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to strengthen web security.
  2. Publish a clear security policy and incident response contact information on the website to improve transparency and readiness.
  3. Verify and update WHOIS domain registration information to ensure consistency and trustworthiness.
  4. Consider adding a security.txt file to facilitate responsible vulnerability disclosure.
  5. Add verified company contact emails and phone numbers on the website to improve business credibility and user trust.

Technical notes

Notes

The website is built on TYPO3 CMS, a robust and mature content management system. It uses modern frontend libraries such as Slick Slider for UI components and integrates Google Analytics and Google Tag Manager for analytics and marketing. The site is mobile-optimized with responsive design and good accessibility features. Performance is moderate, likely due to the use of compressed CSS and JavaScript assets. The meta tags and structured data (JSON-LD) are properly implemented for SEO and social media sharing. Hosting provider details are not explicitly found. The site does not show signs of technical debt or outdated technologies but could benefit from enhanced security headers and performance tuning.
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.
