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

Tipy na Letenky Levné Lety is a Czech Republic-based travel deals website specializing in offering discounted flights, weekend stays, and vacation packages primarily targeting travelers from Prague, Brno, and Vienna. The site operates as an affiliate marketing platform, leveraging partnerships with known travel brands such as Pelikan to provide curated offers. The website is built on WordPress with modern frontend technologies like Bootstrap and jQuery, delivering a good user experience with mobile optimization and clear navigation. However, it lacks direct contact information and formal privacy or terms of service pages, which impacts trust and compliance perception. Security posture is adequate with HTTPS enabled but could be improved by adding security headers and formal security policies. Overall, the site is functional, safe, and moderately trustworthy but would benefit from enhanced privacy compliance and security best practices.

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. 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

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 website occupies a niche in the travel and transportation sector, focusing on budget-conscious travelers seeking affordable flights and vacation deals. Its business model relies on affiliate commissions from flight and travel bookings. The site targets primarily Czech and nearby European customers, offering localized content and deals. The presence of multiple partner domains indicates a networked affiliate ecosystem. The relatively recent domain registration in 2022 aligns with a startup or small business profile. The lack of direct company information and contact details suggests a lean operation focused on content aggregation rather than direct service provision.

Security posture

The website demonstrates basic security hygiene by enforcing HTTPS, ensuring encrypted communications. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options leaves it vulnerable to certain web attacks like clickjacking or MIME sniffing. No evidence of exposed sensitive data or vulnerable libraries was found in the HTML content. The site lacks a published security policy or incident response contact, which limits transparency and preparedness for security incidents. Overall, the security posture is moderate but could be significantly improved with standard web security best practices and formal policies.

Recommendations

  1. Implement standard security headers (Content-Security-Policy, X-Frame-Options, X-Content-Type-Options) to enhance protection against common web attacks.
  2. Publish a comprehensive privacy policy and terms of service to improve legal compliance and user trust.
  3. Add clear contact information including support or business emails and phone numbers to enhance credibility and user support.
  4. Establish a security policy page and provide incident response contact channels to demonstrate security readiness.
  5. Regularly update WordPress core, themes, and plugins to mitigate vulnerabilities and maintain platform security.

Technical notes

Notes

The website is built on WordPress 6.8.2, utilizing Bootstrap for responsive design and jQuery for client-side scripting. It integrates an external affiliate flights widget from Pelikan, indicating reliance on third-party services for core functionality. The site loads external fonts from Google Fonts and uses Font Awesome for icons. Performance is moderate with no major issues detected, and mobile optimization is good. SEO is supported by proper meta tags and structured navigation menus. Accessibility is basic but could be improved with ARIA roles and better semantic markup. The hosting provider is not explicitly identified from the HTML content. Overall, the technical infrastructure is modern and suitable for the site's business model but could benefit from enhanced accessibility and 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.
