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

Fritz HOLTER GmbH operates a comprehensive website focused on sanitary and heating wholesale distribution in Austria, with additional services in wellness and pool solutions. The company has a strong market presence with over 150 years of history, targeting both professional installers and end consumers. The website is content-rich, professionally designed, and offers multiple user engagement channels including partner installer search, online bathroom planner, and newsletter subscription. Technically, the site uses modern technologies such as Vue.js and Storyblok CMS, hosted on AWS CloudFront CDN, with good SEO and accessibility practices. However, the security posture is weakened by an invalid or missing SSL certificate, lack of HTTPS enforcement, and absence of modern TLS protocols, which poses a significant risk. Privacy compliance is well addressed with clear privacy and cookie policies and consent mechanisms. Overall, the site is trustworthy and professional but requires urgent SSL/TLS remediation to improve security and user trust.

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

    • 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

  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

  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 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';…

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 business is positioned as a leading sanitary and heating wholesaler in Austria, with a diversified service offering including consulting, planning, and a partner installer network. The business model combines wholesale distribution with value-added services and digital tools like an online bathroom planner app. The company targets installers, planners, architects, and end consumers, indicating a B2B and B2C hybrid approach. The presence of career pages and social media links suggests active growth and engagement strategies. The domain age and WHOIS data support the legitimacy and long-standing market presence. Partnerships with external platforms like palettehome.de and karriere.at enhance the ecosystem and customer reach.

Security posture

The website demonstrates basic security best practices with several security headers configured, including HSTS, X-Content-Type-Options, and X-XSS-Protection. However, the absence of a valid SSL certificate and lack of HTTPS support critically undermine the security posture. No vulnerable libraries or known exploits are detected, but the lack of TLS 1.2 or higher and missing OCSP stapling reduce security and performance. There is no evidence of published incident response or vulnerability disclosure policies, which could be improved to enhance security culture and transparency. Overall, the site is at risk due to missing SSL and should prioritize certificate renewal and HTTPS enforcement.

Recommendations

  1. Renew and properly configure SSL/TLS certificates to enable HTTPS across the entire site.
  2. Enable TLS 1.2 or higher protocols and strong cipher suites to improve security and performance.
  3. Implement OCSP stapling and session resumption to enhance SSL performance and security.
  4. Publish a security policy and vulnerability disclosure program to improve transparency and incident response readiness.
  5. Maintain and regularly audit privacy and cookie consent mechanisms to ensure ongoing GDPR compliance.
Technical notes

Notes

The website is built on a modern technology stack including Vue.js for frontend interactivity and Storyblok as the CMS. Hosting is via AWS CloudFront CDN with nginx as the web server. The site includes integrations with Google Maps API, Google Tag Manager, and Cookiefirst for consent management. Performance metrics indicate no load time data available, but the site is likely moderate in speed due to chunked transfer encoding and multiple large images. Mobile optimization and accessibility are good, with responsive design and ARIA roles. SEO is well implemented with meta tags, Open Graph, and canonical links. Technical debt is low, but SSL misconfiguration is a critical risk that needs immediate attention.
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.
