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

frogblue Smart Home Systems is a German-based company specializing in wireless smart home and building technology solutions. Their product portfolio includes lighting, heating, blind control, alarm systems, and video door intercoms, all controllable via a single app. The company emphasizes energy efficiency, security, and ease of installation with a mature Bluetooth mesh technology. The website is professionally designed, multilingual, and provides comprehensive user and privacy information, reflecting a mature digital presence. Technically, the site is built on WordPress with modern plugins and analytics tools, ensuring good performance and SEO. Security posture is strong with HTTPS, hCaptcha, and GDPR-compliant cookie management, though some security headers are missing and no explicit security policy or incident response contacts are published. WHOIS data is unavailable, which is a concern but the overall site and business indicators suggest legitimacy. Strategic recommendations include enhancing security headers, publishing a security policy, and adding vulnerability disclosure mechanisms to improve trust and compliance.

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

3 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 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. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Domain Expires Soon

      Domain expires in 16 days

      What to do: Renew domain registration before expiration

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

frogblue positions itself as a specialist in smart, wireless building automation with a focus on energy savings and security. Their business model revolves around product sales and software licensing with a strong emphasis on user-friendly configuration and reliability. The company targets homeowners, installers, and building managers seeking flexible and secure smart home solutions. Their market position is strengthened by German engineering quality and certifications like VDE. The website supports multiple languages, indicating an international market approach. Partnerships include an official shop domain. The company maintains active social media channels and provides detailed contact information, enhancing credibility and customer engagement.

Security posture

The website demonstrates a good security maturity level with enforced HTTPS, use of hCaptcha for form protection, and a GDPR-compliant cookie consent mechanism. The Bluetooth mesh technology described is encrypted and timestamped, indicating secure product design. However, the absence of key security headers (e.g., CSP, HSTS) and lack of a published security policy or incident response contact reduce the overall security posture. No vulnerabilities or exposed sensitive data were detected in the analysis. The site should improve transparency by publishing a security policy and vulnerability disclosure to enhance incident response readiness and user trust.

Recommendations

  1. Implement comprehensive HTTP security headers including Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), X-Frame-Options, and X-Content-Type-Options.
  2. Publish a formal security policy and incident response contact information on the website.
  3. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Regularly audit and update third-party scripts and plugins to mitigate potential vulnerabilities.
  5. Enhance website accessibility features to improve compliance and user experience.

Technical notes

Notes

The website is built on WordPress CMS with a modern tech stack including Yoast SEO, Gravity Forms, Matomo and Google Analytics for tracking, and Real Cookie Banner Pro for privacy compliance. It uses jQuery and other JavaScript libraries for UI enhancements and AJAX search functionality. The site is multilingual with language switcher support. Performance is moderate with preloading and deferred scripts. Mobile optimization is good with responsive design. However, some accessibility features could be improved. Hosting provider details are not explicit. Overall, the technical infrastructure supports a professional and user-friendly experience but could benefit from enhanced security configurations and performance tuning.
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.
