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

Cestovatelský fotodeník is a Czech travel photo diary platform focusing on the documentation and sharing of photographs of town halls and historical sites across Czechia. It is affiliated with the Association of Historical Towns of Bohemia, Moravia and Silesia, indicating a cultural and non-profit orientation. The platform offers interactive maps, photo contests, and user registration, supported by a mobile app for iOS and Android, reflecting a moderate level of digital maturity. The website is professionally designed with good content relevance and navigation clarity, targeting travel enthusiasts and cultural heritage audiences within Czechia. Technically, the site uses jQuery, Leaflet.js for mapping, and a custom CMS named Public4u. The site is mobile optimized and uses HTTPS, but lacks some modern security headers and explicit privacy policies, which are areas for improvement. No major vulnerabilities or tracking technologies were detected in the provided content, suggesting a moderate security posture. The absence of WHOIS data for the domain raises concerns about domain registration legitimacy and trustworthiness, although the website content and business information appear professional and consistent with its cultural mission. Contact information is clearly provided, and cookie consent mechanisms are implemented, supporting basic privacy compliance. Overall, the site presents a trustworthy and valuable resource for its niche audience but should address domain registration transparency and enhance security and privacy policies to improve trust 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

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. 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 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 platform operates in the government and non-profit cultural heritage sector, serving a niche market of travel and history enthusiasts in Czechia. Its business model revolves around community engagement through photo contests and educational content rather than commercial revenue. The presence of a mobile app and interactive map indicates investment in user experience and digital engagement. The company behind the platform, as4u.cz, s.r.o., appears to be a small-sized entity focused on supporting cultural and historical initiatives. The lack of WHOIS data is a notable risk factor but does not detract from the platform's apparent legitimacy and community value. Partnerships include the Association of Historical Towns and social media presence on Facebook, supporting outreach and user interaction.

Security posture

The website enforces HTTPS and includes a cookie consent mechanism, which are positive security and privacy practices. However, the absence of security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces the overall security posture. No evidence of vulnerable libraries or exposed sensitive data was found in the HTML content. The site lacks explicit security or incident response policies, which could be improved to enhance readiness and compliance. Overall, the security maturity is moderate, with room for improvement in headers and documented policies.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection to strengthen defense against common web attacks.
  2. Publish a clear and comprehensive privacy policy and terms of service to improve transparency and GDPR compliance.
  3. Investigate and resolve the missing WHOIS data to ensure domain registration legitimacy and improve trustworthiness.
  4. Enhance accessibility features to meet modern standards and improve user experience for all visitors.
  5. Develop and communicate an incident response plan and security policy to demonstrate security governance and preparedness.

Technical notes

Notes

The website uses a combination of jQuery, jQuery UI, and Leaflet.js for interactive maps, supported by a PHP-based CMS called Public4u. The site loads multiple JavaScript files for UI and gallery functionality and includes mobile menu scripts and calendar widgets. The presence of a mobile app and QR codes indicates a multi-platform approach. Performance appears moderate with no obvious broken elements. SEO is basic with meta keywords and description but lacks advanced structured data like JSON-LD or Open Graph tags. Accessibility is basic with some ARIA roles but could be improved. The hosting provider and server details are not disclosed in the HTML content.
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.
