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. 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"

    • 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';…
  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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

KNV holds a solid market position in the Austrian energy sector, focusing on heat pumps and energy-efficient systems. Their competitive advantage lies in their comprehensive product range, innovative technologies like the KNV S-Series and Smart Price Adaption, and a wide network of over 250 installation partners. The business model is B2B and B2C hybrid, leveraging direct sales and partner channels. Revenue streams likely include product sales, installation services, and after-sales support. The company demonstrates growth potential through technology innovation and sustainability trends. Partnerships with NIBE and integration of smart home components indicate strategic ecosystem development.

Security posture

The website demonstrates a good security maturity level with enforced HTTPS, use of Google reCAPTCHA on forms to prevent abuse, and a detailed cookie consent mechanism compliant with GDPR. Security headers are partially implemented, and no critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of a public security policy, vulnerability disclosure program, or incident response contact reduces transparency and readiness perception. Regular audits of third-party scripts and formalization of security governance documents are recommended to enhance security posture further.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Implement a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Provide clear incident response contact information for security issues.
  4. Regularly review and update third-party scripts and plugins to mitigate vulnerabilities.
  5. Enhance transparency by publishing data protection officer contact details and compliance certifications.

Technical notes

Notes

The website is built on a modern WordPress CMS platform with WooCommerce for e-commerce capabilities. It uses popular plugins such as Yoast SEO for search optimization and integrates Google Tag Manager and Analytics for tracking. The site loads moderate external resources including fonts and embedded scripts from Mavenoid and Google services. Mobile optimization and accessibility are well addressed, with responsive design and ARIA roles. Performance is moderate, with potential improvements in script loading and caching. The technical stack is standard for professional business websites, with no significant technical debt or risks identified.
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.
