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

ČeskýKrumlov.com is a well-established regional tourism information portal focused on Český Krumlov, Czech Republic. It provides comprehensive information about local attractions, cultural events, accommodation options, and practical visitor information. The site integrates affiliate booking services and social media channels to enhance user engagement and monetization. The business is operated by Alcedo Media, s.r.o., with a domain age dating back to 1998, indicating a mature presence in the market. Technically, the website uses common JavaScript libraries and tracking tools such as jQuery, Google Analytics, Facebook SDK, and Smartlook, reflecting a moderate level of digital maturity. The site is mobile-optimized and offers a good user experience with clear navigation and relevant content. Security posture is adequate with HTTPS enabled and domain transfer protection, but lacks DNSSEC and advanced security headers. Privacy compliance is partial, with a privacy policy present but no cookie consent mechanism detected. Overall, the website is trustworthy and professional but could improve in security and privacy transparency.

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

12 findings rated critical or high. Fix these first.

  1. 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

  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.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • 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

  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 · found on this site
  • 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 targets tourists and visitors interested in Český Krumlov, offering detailed guides, event calendars, and accommodation booking. Its business model relies on affiliate marketing (notably Booking.com) and advertising partnerships with regional tourism-related sites. The company maintains partnerships with local and regional tourism websites, enhancing its ecosystem. The site’s longevity and consistent branding position it as a key regional player. Growth opportunities include expanding digital marketing and improving compliance to meet evolving privacy regulations.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is enforced, and domain transfer is restricted, which are positive indicators. However, the absence of DNSSEC and security headers such as Content-Security-Policy or X-Frame-Options reduces resilience against DNS spoofing and clickjacking attacks. No public security or incident response policies were found, which may impact incident handling readiness. The use of multiple third-party scripts increases the attack surface and necessitates regular security audits. GDPR compliance is partial due to missing cookie consent mechanisms.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement standard security headers (CSP, X-Frame-Options, X-Content-Type-Options) to mitigate common web attacks.
  3. Add a cookie consent banner/mechanism to comply fully with GDPR requirements.
  4. Publish clear security and incident response policies to improve transparency and readiness.
  5. Regularly review and update third-party scripts to minimize vulnerabilities and privacy risks.

Technical notes

Notes

The website uses a combination of jQuery, Moment.js, and DateRangePicker for UI components, along with Google Analytics and Facebook SDK for tracking and marketing. The presence of Smartlook indicates session recording capabilities. The site appears custom-built or uses a proprietary CMS, with no major CMS detected. Performance is moderate with room for optimization. Mobile responsiveness is good, but accessibility features are basic. SEO is supported by proper meta tags and structured navigation. Hosting provider details are not explicit. Technical debt is moderate, with opportunities to modernize the tech stack and improve security configurations.
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.
