Security score

61/100

Risk levelMedium

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

Eugen Pfeifer GmbH is a medium-sized German company specializing in climate technology, including planning, installation, and operation of climate, air, and refrigeration systems. The company targets both industrial and private customers, emphasizing tailored solutions for air conditioning and industrial refrigeration. Their market position is that of an experienced regional specialist with a focus on quality and customer service. Technically, the website is built on Joomla CMS with Bootstrap and jQuery, offering a modern and responsive user experience, though some accessibility and SEO improvements are possible. Security posture is solid with HTTPS and cookie consent mechanisms, but lacks advanced security headers and incident response information. Overall, the site is professional and trustworthy, though contact information is not explicitly presented on the homepage, which could be improved for better business credibility.

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

6 findings rated critical or high. Fix these first.

  1. GDPR outside view

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

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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 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
  • 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 operates in the energy sector, focusing on HVAC and refrigeration services. Its business model revolves around providing comprehensive climate technology solutions including consulting, installation, and maintenance. The website reflects a stable, medium-sized enterprise with a clear service offering and consistent branding. There is no evidence of partnerships or subsidiaries from the website content. The absence of social media and limited contact details may indicate a traditional business approach focused on direct client relationships. The company appears to have a solid regional presence with potential for growth by enhancing digital engagement and transparency.

Security posture

The website enforces HTTPS and implements a cookie consent mechanism that blocks cookies and storage until user acceptance, demonstrating good privacy respect. However, it lacks important security headers such as Content-Security-Policy and X-Frame-Options, which could mitigate common web attacks. No vulnerability disclosure or incident response contacts are provided, which limits transparency in security management. No exposed sensitive data or vulnerable libraries were detected. Overall, the security posture is moderate but could be significantly improved by adopting additional security best practices and providing clear security policies.

Recommendations

  1. Implement security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web vulnerabilities.
  2. Add a dedicated security or incident response page with contact information to improve transparency and readiness.
  3. Publish a terms of service page to clarify user and business obligations.
  4. Enhance accessibility features to comply with standards and improve user experience for all visitors.
  5. Include clear contact information such as company phone numbers and emails on the website to increase business credibility and user trust.

Technical notes

Notes

The website is built on Joomla 4.4.0 CMS with Bootstrap 5.3.2 and jQuery 3.7.1, indicating a modern and maintainable technology stack. The site uses responsive design with Google Fonts integration and a cookie consent mechanism that disables cookies and storage until consent is given. Performance is moderate with no obvious errors or broken elements. SEO is basic with meta description and structured data for breadcrumbs but lacks Open Graph or Twitter Card metadata. Accessibility is basic but could be improved. Hosting provider details are not disclosed in the HTML. Overall, the technical implementation is solid but could benefit from enhanced SEO and accessibility improvements.
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.
