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

SHT Haustechnik GmbH is a leading Austrian wholesaler specializing in sanitary, heating, installation, and electrical products, serving primarily professional installers and industry partners. The company operates a comprehensive digital presence including a WordPress-based website, an online shop (sht.at), and regional offices across Austria, positioning itself as the market leader in the haustechnik sector. The website content is well-structured, professionally designed, and includes customer testimonials and partner logos, reinforcing trust and credibility. Technically, the site uses a modern WordPress stack with PHP 8.1 and React components, but lacks a valid SSL certificate and HTTPS support, which is a critical security deficiency. Privacy compliance is addressed with a cookie consent mechanism and clear privacy and terms of service pages. However, the absence of HTTPS and security headers significantly undermines the security posture. Strategic recommendations include immediate SSL deployment, enabling modern TLS protocols, and enhancing security headers and policies to protect user data and improve 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

8 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

  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 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

Business profile

SHT Haustechnik GmbH leverages its strong industry partnerships and extensive product range (over 800,000 articles) to maintain a dominant position in the Austrian haustechnik wholesale market. Its business model combines traditional regional service with digital transformation via an online shop and mobile app, targeting professional installers and industry clients. The company benefits from its parent Frauenthal Holding's backing and maintains a robust partner ecosystem including ISZ and Bad & Energie. The website reflects a mature digital strategy with marketing tools like Facebook Pixel and consent management, supporting customer engagement and compliance. Growth indicators include active bonus programs and frequent news updates. The company’s market positioning is reinforced by consistent branding and comprehensive service offerings.

Security posture

The website's security posture is currently weak due to the lack of HTTPS and a valid SSL certificate, exposing users to potential data interception and undermining trust. While no critical vulnerabilities like Heartbleed or POODLE were detected, the exposure of PHP version information and absence of security headers such as HSTS and Content-Security-Policy increase risk. No incident response or security policy information is published, limiting transparency and preparedness. Privacy compliance is partially addressed through cookie consent and privacy policy presence. Immediate remediation of SSL/TLS issues and implementation of security best practices are essential to mitigate risks and align with GDPR and industry standards.

Recommendations

  1. Deploy a valid SSL/TLS certificate and enforce HTTPS site-wide immediately.
  2. Enable modern TLS protocols (TLS 1.2 and TLS 1.3) and disable insecure protocols.
  3. Implement HTTP security headers including HSTS, Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options.
  4. Remove or obfuscate server and PHP version information from HTTP headers.
  5. Publish a clear security policy and incident response contact information on the website.
  6. Enhance privacy compliance by detailing data retention policies and user rights.
  7. Conduct regular security audits and vulnerability scans to maintain a strong security posture.
  8. Improve website performance metrics and accessibility features for better user experience.
  9. Expand contact information to include verified company phone numbers for customer support.
  10. Maintain consistent branding and update marketing tools to ensure transparency and user trust.

Technical notes

Notes

The website runs on a WordPress 6.7.2 CMS with PHP 8.1 and Apache 2.4 on Windows hosting. It uses modern JavaScript libraries including React and Bootstrap for UI components. SEO is enhanced via Yoast SEO plugin and structured data (JSON-LD) is implemented for organization and breadcrumb schema. The site integrates third-party services such as Consentmanager for cookie compliance and Facebook Pixel for marketing analytics. However, the absence of HTTPS and valid SSL certificate is a major technical risk. Performance data is missing, indicating potential slow loading times. Mobile optimization is good, but accessibility is basic. Hosting provider details are not explicitly identified. Overall, the technical infrastructure is modern but requires urgent security upgrades and performance optimization.
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.
