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

Krušnohorci.cz is a well-established Czech regional travel portal focused on the Krušné hory mountain region, providing travel tips, event information, accommodation listings, weather updates, and news. The site targets tourists and locals interested in exploring the region's natural and cultural attractions. The business model relies on content provision combined with advertising revenue and community engagement. Technically, the site uses a mix of Google Fonts, Font Awesome, jQuery 1.12.4, Google Custom Search, Adsense, and Google Tag Manager, hosted on a Czech hosting provider. The website is moderately performant, mobile-optimized, and SEO-friendly but uses an outdated jQuery version which poses some security risks. Security posture is generally good with HTTPS enforced and a consent management platform for cookies, though some security headers are not explicitly detected. Privacy compliance is strong with a comprehensive privacy policy and cookie consent mechanism. Contact information is available via email and contact forms, but no phone numbers or physical addresses are provided. Overall, the site is professional, trustworthy, and safe for general audiences.

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

11 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

The portal occupies a niche regional tourism market with a focus on the Krušné hory area, leveraging rich content and community-driven event promotion. Its competitive advantage lies in localized, detailed travel content and integration of weather and webcam data. The business model is content and advertising-driven, with partnerships evident through related domains and social media channels. Growth potential exists through enhanced digital marketing and possible expansion of services. The site maintains a consistent brand and active social media presence, supporting user engagement and trust.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and a cookie consent platform compliant with GDPR. However, the use of an outdated jQuery library (version 1.12.4) introduces potential vulnerabilities. No explicit security policy or incident response information is publicly available, which could hinder transparency and user trust. Security headers such as Content-Security-Policy and X-Frame-Options are not clearly present, representing an area for improvement. No exposed sensitive data or obvious vulnerabilities were detected in the HTML content. Overall, the site is secure but would benefit from updates and enhanced security practices.

Recommendations

  1. Update jQuery to the latest stable version to mitigate known security vulnerabilities.
  2. Implement and verify security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish a clear security policy and incident response contact information to improve transparency and trust.
  4. Enhance accessibility features to comply with standards and improve user experience for all visitors.
  5. Conduct regular security audits and penetration testing to proactively identify and remediate vulnerabilities.

Technical notes

Notes

The website uses a custom or unknown CMS with a technology stack including Google Fonts, Font Awesome, jQuery 1.12.4, Google Custom Search Engine, Google Adsense, and Google Tag Manager. Hosting is provided by cesky-hosting.eu, a Czech hosting provider. The site is moderately performant with good mobile optimization and basic accessibility features. SEO is well addressed with proper meta tags and Open Graph data. However, the use of an outdated jQuery version indicates some technical debt and potential security risk. The site could benefit from modernization efforts including updating libraries and improving 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.
