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

ATELIÉR Klein is a Czech architectural design firm specializing in low-energy and passive family houses as well as commercial buildings. Their services include interior design, project documentation, and energy consulting, with a strong focus on energy efficiency and subsidy program support. The website reflects a small but professional business with consistent branding and a clear market position in the Czech Republic's real estate and energy sectors. Technically, the site is built on WordPress with modern scripts and integrations such as Google reCAPTCHA and Facebook Pixel, indicating a moderate level of digital maturity. Security posture is good with HTTPS and some security best practices, though there is room for improvement in security headers and incident response transparency. Overall, the site is trustworthy, GDPR compliant, and provides clear privacy and cookie policies, but lacks explicit contact details and terms of service. The domain WHOIS data is unavailable, likely due to privacy protection, but the website content and partner references support legitimacy.

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

9 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

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

  2. 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';…

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 company targets private and commercial clients interested in sustainable and energy-efficient building solutions. Their business model revolves around architectural design and consulting, leveraging expertise in subsidy programs like Nová zelená úsporám. The presence of partner companies in construction, wood production, and development suggests a collaborative ecosystem enhancing their service offerings. The website's content and social media presence support a credible market position, though the absence of direct contact information on the site may limit immediate client engagement. Growth potential exists through expanding digital presence and formalizing security and compliance disclosures.

Security posture

The website demonstrates a baseline security maturity with HTTPS enforced and integration of Google reCAPTCHA to protect forms. Facebook Pixel is used for marketing and tracking, which is common but requires privacy considerations. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the lack of HTTP security headers and absence of a security policy or incident response information indicate gaps in security governance. The missing WHOIS data reduces transparency but is justified by privacy protection. Overall, the security posture is adequate for a small business but could be enhanced by implementing recommended headers, publishing a security.txt file, and improving accessibility compliance.

Recommendations

  1. Implement HTTP security headers such as Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security to enhance protection against common web attacks.
  2. Publish a security policy and incident response contact information on the website to improve transparency and readiness.
  3. Add a security.txt file at the root domain to facilitate vulnerability reporting and improve security communication.
  4. Enhance accessibility features to comply with standards and improve user experience for all visitors.
  5. Consider adding explicit contact information such as company phone numbers and emails to improve business credibility and client trust.

Technical notes

Notes

The website is built on WordPress 6.2.8, using jQuery 3.5.1 and popular plugins like Slick Slider for UI components. Google reCAPTCHA is integrated for bot protection, and Facebook Pixel is used for marketing analytics. The site loads CSS and JS asynchronously where appropriate, aiding performance. Mobile optimization is good, with responsive design and viewport meta tags. SEO is supported by meta descriptions, Open Graph tags, and structured data for social sharing. No major technical debt or deprecated technologies were detected. Hosting provider details are not disclosed. Performance is moderate, with potential improvements in caching and resource optimization. Accessibility is basic and could be improved with ARIA roles and better keyboard navigation support.
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.
