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

7 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. 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

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  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 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 holds a stable position in the regional construction engineering market in Brno, Czech Republic, as part of a larger holding. Its business model focuses on providing engineering and project management services for residential, civil, and industrial construction projects. The website content and structure suggest a focus on quality, client collaboration, and timely delivery. The presence of certifications and awards adds to its credibility. The lack of public WHOIS data is balanced by clear company identification on the site. The company targets developers, architects, and clients seeking engineering expertise. There is no evidence of e-commerce or direct sales, indicating a service-oriented business model. The use of modern web technologies and compliance with privacy regulations suggests a moderate level of digital maturity.

Security posture

The website enforces HTTPS and includes a cookie consent banner with advanced settings, demonstrating awareness of privacy and security best practices. However, no explicit security headers such as Content-Security-Policy or X-Frame-Options were detected, which could improve protection against common web attacks. There is no visible security policy or incident response contact information, and no security.txt file was found for vulnerability disclosure. No exposed sensitive data or vulnerable libraries were identified. The use of Google Tag Manager introduces moderate user tracking, but privacy compliance appears adequate. Overall, the security posture is good but could be enhanced with additional headers and explicit security policies.

Recommendations

  1. Implement standard security headers (CSP, X-Content-Type-Options, X-Frame-Options) to strengthen web security.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and readiness.
  3. Consider adding a security.txt file to facilitate responsible vulnerability disclosure.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Regularly review and update privacy and cookie policies to maintain GDPR compliance and user trust.

Technical notes

Notes

The website is built on the Webnode CMS platform, utilizing Amazon Cloudfront CDN for content delivery, which supports good performance and scalability. The tech stack includes standard web technologies such as HTML5, CSS, and JavaScript. The site is mobile-optimized with responsive design and includes SEO meta tags and Open Graph metadata for social sharing. Google Tag Manager is used for analytics and marketing tracking. Performance is moderate, with no major issues detected. The site lacks advanced frameworks or custom backend technologies visible from the front end. Opportunities exist to improve accessibility and implement additional security headers to reduce technical risks.
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.
