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

8 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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

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 business operates in the education and non-profit sectors, focusing on cultural heritage and event hosting. It leverages partnerships with local institutions such as the Mendel Museum and is co-financed by regional and EU programs. The business model centers on venue rental and educational activities, targeting event organizers, tourists, and the general public interested in Mendel's legacy. The company is relatively new, founded in 2022, aligning with the recent construction of the greenhouse. The partnership ecosystem is strong, enhancing its market position in Brno's cultural landscape.

Security posture

The website employs HTTPS and uses a GDPR-compliant cookie consent plugin, indicating a baseline security and privacy awareness. However, the absence of explicit security headers like Content-Security-Policy and X-Frame-Options suggests room for improvement. No incident response or security policy pages are present, which could be a gap in transparency and preparedness. The contact form uses validation, reducing risk of injection attacks, but no vulnerability disclosure or security.txt is found. Overall, the security posture is moderate with recommendations to enhance header policies and publish security documentation.

Recommendations

  1. Implement comprehensive security headers including CSP, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a dedicated security policy and vulnerability disclosure page to improve transparency.
  3. Regularly update WordPress core and plugins to mitigate known vulnerabilities.
  4. Enhance accessibility features to improve compliance and user experience.
  5. Consider adding terms of service and data protection officer contact information for completeness.

Technical notes

Notes

The website is built on WordPress with PHP and jQuery, integrating Google Maps API and Contact Form 7 for interactive features. Hosting is provided by Wedos, a reputable Czech hosting provider. The site shows good mobile responsiveness and SEO optimization with proper meta tags and structured data (JSON-LD). Performance is moderate, with some lazy loading and preloading optimizations. Technical debt appears low, but security header implementation and accessibility could be improved. The site uses Google Analytics and Tag Manager for analytics and marketing purposes.
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.
