Risk levelMedium

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

Mind Mystery is a small experiential museum based in the Netherlands, specializing in illusions and interactive exhibits designed to engage visitors in discovering perceptual phenomena. The website is built on WordPress and uses common plugins such as Yoast SEO and WP Rocket, indicating a moderate level of technical maturity. The site is well-structured with good design and navigation, optimized for mobile devices, and employs Google Fonts for typography. However, the site lacks critical privacy and cookie policies, security headers, and explicit contact information, which are important for compliance and trust. No advanced security measures or incident response information are present, suggesting room for improvement in security posture. Overall, the website is safe for general audiences and presents a professional image consistent with a niche museum business.

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

2 findings rated critical or high. Fix these first.

  1. 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

  2. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

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 hospitality sector as a niche museum focused on illusions, targeting general visitors interested in experiential learning and entertainment. The business model revolves around visitor admissions and interactive exhibits. The website positions Mind Mystery as a unique local attraction with consistent branding and good content quality. There is no evidence of parent companies or subsidiaries. The lack of detailed business contact information and policies may limit trust and growth potential. The use of WordPress and SEO tools suggests an intent to reach a wider audience online, but the absence of analytics and marketing tools indicates limited digital marketing sophistication.

Security posture

The website currently exhibits a basic security posture with HTTPS presumably enabled (not explicitly confirmed in the HTML snippet), but no security headers such as Content-Security-Policy or Strict-Transport-Security were detected. There are no visible vulnerabilities or exposed sensitive data in the HTML content. The absence of privacy and cookie policies, security.txt, or incident response contacts indicates gaps in compliance and readiness. The site does not appear to use tracking or analytics scripts that could introduce privacy risks. Overall, the security maturity is low to moderate, with recommendations to implement standard security headers, privacy policies, and incident response mechanisms to enhance protection and compliance.

Recommendations

  1. Implement comprehensive privacy and cookie policies with clear GDPR compliance statements.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, X-XSS-Protection, and Strict-Transport-Security.
  3. Publish contact information including emails and phone numbers for general and security-related inquiries.
  4. Establish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Integrate analytics and marketing tools with privacy-compliant consent mechanisms to improve digital marketing effectiveness.

Technical notes

Notes

The website is built on WordPress with Yoast SEO and WP Rocket plugins, indicating a standard CMS infrastructure optimized for SEO and caching performance. Google Fonts are used for typography. The site appears mobile-optimized with responsive design elements. No advanced JavaScript frameworks or modern frontend technologies were detected. Performance is moderate, with some font preloading for optimization. Accessibility features are basic but present. The lack of security headers and privacy policies suggests technical debt in security and compliance areas. Hosting provider details were not identified from the HTML content. Overall, the technical stack is conventional and stable but could benefit from modernization in security and privacy implementations.
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.
