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

Recuair is a Czech-based manufacturer specializing in decentralised heat recovery ventilation units designed to improve indoor air quality by providing smart, automatic ventilation with air and heat recovery. Their products target homeowners, apartment residents, and offices seeking energy-efficient, quiet, and allergen-free ventilation solutions. The company collaborates with academic institutions to develop patented technology, positioning itself as a leader in the Czech ventilation market. The website reflects a professional digital presence built on Joomla CMS with modern frameworks and includes remote monitoring features for their products. Security posture is generally good with HTTPS and CSRF protections, though some security headers and explicit policies are missing. Privacy compliance is basic, with a cookie consent mechanism but no visible privacy or terms of service pages. WHOIS data is unavailable, raising questions about domain registration status, but the website content and branding appear consistent and trustworthy. Overall, the site demonstrates a solid business and technical foundation with room for improvement in transparency and security documentation.

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. 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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

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

Recuair operates in the energy sector, focusing on ventilation technology with heat recovery. Their competitive advantage lies in patented technology developed with universities, offering energy savings, noise reduction, and allergen filtration. The business model includes manufacturing, direct sales, and remote monitoring services. Target customers include residential and commercial property owners valuing indoor air quality and energy efficiency. The company emphasizes ease of installation and long-term service life. The website supports marketing and customer engagement but lacks direct contact details and comprehensive privacy/legal policies. The partnership ecosystem includes academic institutions and uses third-party marketing and analytics services. Growth indicators are not explicit but implied by technology innovation and warranty offerings.

Security posture

The website employs HTTPS with a good SSL configuration and uses CSRF tokens for AJAX requests, indicating awareness of common web security practices. However, it lacks explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options, which could enhance protection against clickjacking and MIME sniffing. No vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of published security policies or incident response contacts limits transparency and preparedness communication. Tracking and advertising scripts are present, requiring clear privacy disclosures to comply with GDPR and other regulations. Overall, the security maturity is moderate but could be improved with additional headers and policy documentation.

Recommendations

  1. Implement and publish a comprehensive privacy policy and terms of service pages to improve compliance and user trust.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance web security.
  3. Provide explicit contact information including company emails and phone numbers for customer support and security incident reporting.
  4. Publish an incident response policy and security contact channels to demonstrate readiness and transparency.
  5. Verify and update WHOIS registration data to ensure domain legitimacy and reduce suspicion.

Notes

The website is built on Joomla CMS using the Helix Ultimate framework, leveraging modern JavaScript libraries such as jQuery and LayerSlider for interactive content. It integrates multiple marketing and analytics tools including Google Tag Manager, Facebook Pixel, Bing Ads, and Seznam Analytics. The site is mobile responsive with good SEO metadata and structured navigation. Performance is moderate, with some heavy slider images and multiple external scripts. Accessibility features are basic but present. The technical stack is modern and well-maintained, though opportunities exist to optimize loading times and enhance accessibility compliance.
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.
