Risk levelHigh

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

The website dalekohled.cz is an educational platform focused on providing clear and insightful learning experiences, including educational excursions and summer camps primarily targeting school-age children and educators in the Czech Republic. The site is built on WordPress using standard technologies such as Bootstrap and jQuery, offering a responsive and user-friendly interface. However, it lacks advanced SEO and accessibility features and does not implement structured data or Open Graph metadata. From a security perspective, the site uses HTTPS but lacks important security headers and does not provide privacy or cookie policies, which are critical for GDPR compliance. No contact information or incident response channels are explicitly provided, limiting transparency and trust. No analytics or advertising scripts were detected, indicating minimal user tracking but also a lack of marketing tools. Overall, the website appears legitimate and consistent with its domain age and educational purpose. However, it would benefit from improved security practices, privacy compliance, and clearer contact information to enhance trustworthiness and user confidence.

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

10 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

  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"

    • 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

Dalekohled.cz operates in the education sector, providing experiential learning programs such as excursions and summer camps. Its market position is niche, focusing on Czech school children and educators. The business model appears to be service-oriented, possibly non-profit or community-focused, with no evident commercial transactions on the site. The site has partnerships or references to related educational sites but no clear parent or subsidiary companies. Growth indicators are limited due to minimal marketing and analytics presence. The partnership ecosystem includes educational museums and institutions referenced in content but not linked as domains. The company has maintained the domain since 2003, indicating stability.

Security posture

The security posture of dalekohled.cz is basic. HTTPS is enabled, which is essential, but the absence of security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security reduces protection against common web attacks. No vulnerability disclosures or incident response policies are visible, and no contact channels for security issues are provided. The lack of privacy and cookie policies indicates non-compliance with GDPR requirements. Forms present are minimal and do not show explicit security measures. Overall, the site is functional but requires significant improvements to meet modern security and privacy standards.

Recommendations

  1. Implement comprehensive privacy and cookie policies with clear GDPR compliance statements.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection.
  3. Provide explicit contact information including emails and phone numbers for general and security-related inquiries.
  4. Conduct a security audit to identify and remediate any vulnerable plugins or libraries.
  5. Enhance accessibility and SEO by adding structured data, Open Graph tags, and improving site navigation.

Technical notes

Notes

The website uses WordPress CMS version 6.4.5 with a custom theme 'iamsocial' and standard libraries such as jQuery and Bootstrap for frontend functionality. Google Fonts are used for typography. The site is responsive and mobile-friendly but lacks advanced SEO features like structured data or Open Graph metadata. Performance is moderate with no evident optimization or caching mechanisms detected. No analytics or tracking scripts are present, indicating minimal data collection. The hosting provider is not explicitly identified but DNS points to REG-ZONER registrar name servers. The site uses HTTPS but lacks security headers, which is a technical risk. Overall, the technical infrastructure is standard but could benefit from modernization and security enhancements.
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.
