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

Do-muzea.cz is a Czech Republic-based online portal dedicated to providing comprehensive information about museums across the country. The website serves both museum visitors and museum professionals by offering a detailed directory of museums, visitor information, and services tailored to cultural institutions. The site is operated by NETservis s.r.o., as indicated by the author meta tag, and features a professional design with integrated Google Maps for location visualization. Technically, the website employs jQuery 3.2.1, Google Fonts, and Google Maps API, indicating a moderately modern tech stack. The site is mobile-optimized and offers a good user experience with clear navigation and relevant content. However, there is no detected CMS or hosting provider information. Performance is moderate, with no critical errors or broken elements observed. From a security perspective, the site uses HTTPS, which is a fundamental security measure. However, it lacks important security headers such as Content-Security-Policy and X-Frame-Options, which could enhance protection against common web attacks. No vulnerabilities or exposed sensitive data were detected. The absence of privacy and cookie policies, as well as contact information for incident response, indicates gaps in compliance and security transparency. Overall, the website is functional and trustworthy for its intended purpose but would benefit from improved privacy compliance and enhanced security practices. The lack of WHOIS data limits domain trust analysis, but the website content and HTTPS usage suggest legitimate operation. Strategic improvements in security headers, privacy policies, and contact transparency are recommended to strengthen the site's security posture and compliance.

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. 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 website occupies a niche market position as a cultural information portal focused on museums in the Czech Republic. Its business model centers on providing a directory and visitor information, targeting museum visitors and professionals. The key services include museum listings, visitor guidance, and support for museums. The site is operated by NETservis s.r.o., a small-sized entity. There is no evidence of revenue streams such as advertising or affiliate programs, suggesting a primarily informational or non-commercial focus. The absence of social media links and limited external partnerships indicates a focused but modest ecosystem. Growth potential may lie in expanding services, improving user engagement, and enhancing compliance to attract institutional partnerships.

Security posture

The current security posture is moderate. The site benefits from HTTPS encryption, ensuring secure data transmission. However, the lack of security headers reduces protection against clickjacking, MIME sniffing, and cross-site scripting attacks. No incident response or security policy information is provided, which limits preparedness for security events. The absence of vulnerability disclosure or security.txt files further reduces transparency. No tracking or analytics services were detected, minimizing privacy risks from third-party data collection. Overall, the site is secure enough for informational purposes but requires enhancements in security headers, privacy policies, and incident response readiness to meet higher security standards and compliance requirements such as GDPR and NIS2.

Recommendations

  1. Implement essential security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  2. Publish comprehensive privacy and cookie policies to improve GDPR compliance and user trust.
  3. Add clear contact information including emails and phone numbers for general inquiries and security incident reporting.
  4. Consider creating a security.txt file and vulnerability disclosure policy to enhance transparency and security culture.
  5. Regularly review and update WHOIS information to ensure domain registration transparency and trustworthiness.

Technical notes

Notes

The website uses a combination of jQuery 3.2.1, Google Fonts, and Google Maps API, indicating a moderately modern front-end technology stack. The HTML structure is valid and includes meta tags for SEO and mobile optimization. The site is responsive and accessible with basic accessibility features. Performance is moderate with no major issues detected. There is no evidence of a CMS or server-side technologies from the provided data. The site lacks advanced SEO optimizations such as structured data (JSON-LD) or extensive meta descriptions. Hosting provider and infrastructure details are not disclosed. Opportunities exist to modernize the tech stack, improve SEO with structured data, 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.
