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

ELK GmbH is a well-established Austrian company specializing in prefabricated houses, boasting over 60 years of market leadership. Their website reflects a mature business with a strong brand presence, offering a variety of housing solutions including single-family homes, bungalows, multi-family houses, and apartments. The company emphasizes sustainability and customer service, supported by multiple industry awards and partnerships such as with RB Leipzig. Technically, the website uses modern web technologies including Cloudflare CDN, Bootstrap, jQuery, and Vimeo for video content, ensuring a rich user experience and mobile responsiveness. However, the site lacks a valid SSL certificate, which is a critical security flaw that undermines user trust and data protection. Security headers are properly configured, but the absence of HTTPS and modern TLS protocols significantly lowers the security posture. Privacy compliance is partial, with a privacy policy present but no visible cookie consent mechanism. Contact information is primarily via contact forms and social media channels, with no explicit emails or phone numbers displayed. Overall, ELK GmbH's digital presence is professional and content-rich but requires urgent improvements in security and privacy compliance to align with best practices and regulatory requirements.

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. 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

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • 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. 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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

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

ELK GmbH operates in the real estate sector focusing on prefabricated housing solutions, targeting families and individuals in Austria and German-speaking markets. Their business model integrates manufacturing, design, and full-service customer support, positioning them as a market leader with a strong reputation. The company leverages partnerships and sponsorships to enhance brand visibility and trust. Their digital ecosystem includes career and vision subdomains, indicating strategic diversification. The website content and awards highlight a commitment to quality, sustainability, and innovation. Marketing efforts utilize Google Tag Manager and Intercom for user engagement and analytics. The absence of direct contact emails and phone numbers suggests a controlled communication channel strategy, likely to manage leads and customer interactions efficiently.

Security posture

The website demonstrates a moderate security maturity level with several positive practices such as HttpOnly and SameSite cookies, security headers, and content security policies. However, the lack of a valid SSL certificate and disabled TLS protocols represent critical vulnerabilities that expose users to risks such as data interception and man-in-the-middle attacks. The site does not implement advanced security features like OCSP stapling or session resumption, and there is no evidence of published incident response or vulnerability disclosure policies. Privacy compliance is partial, with GDPR-aligned privacy policy present but no cookie consent mechanism detected. These gaps could impact user trust and regulatory compliance, necessitating immediate remediation to secure communications and enhance privacy protections.

Recommendations

  1. Install and maintain a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Enable modern TLS protocols (TLS 1.2 and TLS 1.3) and disable deprecated protocols.
  3. Implement a comprehensive cookie consent mechanism to comply with GDPR and ePrivacy regulations.
  4. Publish clear security and incident response policies, including vulnerability disclosure channels.
  5. Enhance privacy compliance by appointing and publishing Data Protection Officer contact details if applicable.
  6. Improve accessibility features and ensure all forms have proper security controls and validation.
  7. Regularly audit third-party scripts and tracking tools to minimize privacy risks.
  8. Consider adding explicit company contact emails and phone numbers for transparency and trust.
Technical notes

Notes

The website is built on a modern technology stack including Bootstrap for responsive design, jQuery for DOM manipulation, Owl Carousel for sliders, and Vimeo for video embedding. It uses Cloudflare as a CDN and proxy, enhancing performance and security at the network level. The CMS appears to be Redaxo or a custom solution with Redaxo conventions. Lazy loading of images is implemented via LazySizes, improving load times and user experience. Google Tag Manager is used for analytics and marketing tags. Despite these strengths, the site lacks a valid SSL certificate and proper TLS configuration, which is a significant technical debt. Performance metrics were not available, but the use of modern frontend technologies and CDN suggests moderate to good performance. SEO is supported by proper meta tags, Open Graph tags, and structured navigation. Accessibility is basic but could be improved with more ARIA roles and semantic markup.
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.
