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

8 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

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  2. 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 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

ESO travel targets Czech-speaking travelers seeking exotic and discovery travel experiences. Their business model focuses on packaged tours and travel services with a medium-sized market presence. The company offers a broad range of destinations and travel types, supported by detailed travel information and client support. The website integrates marketing and tracking tools to optimize customer engagement. The lack of visible certifications or security policies beyond GDPR compliance suggests room for enhanced trust signals. The company appears independent with no parent or subsidiary domains identified.

Security posture

The website enforces HTTPS and uses cookie consent compliant with GDPR, indicating good privacy practices. Tracking scripts from Google and Facebook are present, with user tracking at a moderate level. No security.txt or explicit incident response contacts were found. Security headers are not detected in the provided data, representing an area for improvement. No vulnerabilities or exposed sensitive data were identified. The missing WHOIS data reduces domain trustworthiness but does not directly impact website security. Overall, the security posture is good but could benefit from enhanced header policies and formal vulnerability disclosure mechanisms.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security.
  2. Publish a security.txt file to facilitate vulnerability reporting and improve transparency.
  3. Verify and update WHOIS domain registration information to enhance trust and legitimacy.
  4. Regularly audit third-party scripts and tracking tools for security and privacy compliance.
  5. Enhance contact information with direct company emails for support and incident response.

Technical notes

Notes

The website uses a modern tech stack including jQuery, Foundation CSS framework, Font Awesome icons, and various jQuery plugins for UI components like sliders and date pickers. Google Tag Manager and Facebook Pixel are integrated for analytics and marketing. The site is mobile responsive and SEO optimized with proper meta tags and Open Graph data. Performance is moderate, with potential improvements in loading speed and accessibility features. No CMS was explicitly detected. Hosting provider details are not available from the provided data. Overall, the technical implementation is solid with opportunities for 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.
