Risk levelHigh

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

The website letenkylevnecz.cz is a Czech language travel deals aggregator focused on providing users with tips and affiliate links for purchasing cheap flight tickets and booking accommodations. It targets budget-conscious travelers interested in European and exotic destinations. The site leverages affiliate marketing partnerships with known travel platforms such as Pelikan and Nakup-letenek.cz. Technically, the site uses Bootstrap for styling and includes a cookie consent mechanism, indicating some level of privacy compliance. However, no explicit privacy policy or terms of service pages were found, and no direct company contact information is provided, which limits transparency and trust. Security headers are not detected, and SSL configuration could not be verified from the provided data. Overall, the site is functional, mobile-optimized, and provides relevant content but lacks some critical compliance and security features.

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

9 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. 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

  4. 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 · 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 business operates as a small affiliate marketing entity within the transportation sector, specifically focusing on flight ticket sales and travel deals in the Czech market. Its competitive advantage lies in aggregating discounted flight offers and providing curated travel tips. The business model relies on referral commissions from partner sites. The website's market position is niche and localized, with a focus on Czech-speaking travelers. The partnership ecosystem includes multiple travel and booking platforms, enhancing its service offerings. Growth potential depends on expanding affiliate relationships and improving trust signals such as clear privacy and security policies.

Security posture

The security posture is moderate but with notable gaps. The presence of a cookie consent mechanism is positive, indicating awareness of privacy regulations. However, the absence of visible security headers and lack of explicit privacy and security policies reduce the overall security maturity. No incident response or vulnerability disclosure information is provided. The site does not expose sensitive data or show signs of vulnerabilities in the analyzed content. To improve, the site should implement standard security headers, enforce HTTPS, and provide clear security and incident response information.

Recommendations

  1. Implement and publish a comprehensive privacy policy and terms of service.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Verify and enforce HTTPS across the entire site.
  4. Provide clear contact information including security incident contacts.
  5. Regularly audit third-party scripts and affiliate integrations for security and privacy compliance.

Technical notes

Notes

The website uses a modern front-end stack with Bootstrap CSS and JavaScript, including a third-party cookie consent library and an affiliate flight booking widget from Pelikan. The site is mobile-optimized and has good SEO meta tags. Performance is moderate with no obvious technical debt. No CMS or backend platform was detected, suggesting a static or custom-built site. Hosting provider details are not available. The site could benefit from improved accessibility features and enhanced security configurations to reduce technical risks.
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.
