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

CK Blue Style is a Czech travel agency specializing in offering vacation packages and tours to popular European and exotic destinations such as Greece, Egypt, Tunisia, Turkey, Morocco, Italy, Bulgaria, and more. The website provides a comprehensive catalog of travel options including last minute and first minute deals, family vacations, and premium travel experiences. The company targets a broad audience including families, seniors, and adult travelers seeking quality holiday options. Technically, the website is built using modern web technologies including React and Next.js, with integrations for analytics and cookie consent management. The site is mobile optimized and provides a good user experience with clear navigation and search capabilities. Security-wise, the site enforces HTTPS and uses asynchronous script loading, but lacks some security headers and explicit security policies. The absence of WHOIS data for the domain reduces trustworthiness from a domain registration perspective, though the website content and business presence suggest legitimate operations. Privacy compliance is partial, with cookie consent implemented but no clear privacy or terms of service pages found. Overall, the site is professional and trustworthy but would benefit from improved transparency and security 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

6 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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook

      What to do: Document all third-party data sharing in your privacy policy

  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 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

CK Blue Style holds a solid position in the Czech travel market, offering a wide range of travel services primarily focused on leisure and holiday packages. Their business model revolves around online travel bookings with seasonal promotions to attract customers. The company leverages partnerships with airlines and hotels to provide competitive pricing and diverse destination options. The presence of social media and blog channels supports customer engagement and marketing efforts. Growth indicators include a broad destination portfolio and seasonal campaigns like last minute and first minute offers. The company appears to be medium-sized with a focus on hospitality and tourism sectors. Strategic observations suggest opportunities for enhancing trust through better domain registration transparency and expanded privacy and security disclosures.

Security posture

The website demonstrates a moderate security posture with HTTPS enforced and no visible exposure of sensitive data in the HTML content. However, the lack of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options represents a gap in defense-in-depth. No explicit security policies or incident response contacts are published, which limits transparency and preparedness communication. The use of third-party scripts like Google Tag Manager and Exponea introduces potential risk vectors that require ongoing monitoring. Privacy compliance is partial, with cookie consent mechanisms in place but no detailed privacy policy found. Overall, the security maturity is adequate for a travel agency website but could be improved by implementing recommended headers, publishing security policies, and enhancing privacy disclosures.

Recommendations

  1. Implement and publish a comprehensive privacy policy and terms of service pages to improve transparency and GDPR compliance.
  2. Add essential security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen security posture.
  3. Investigate and resolve the missing WHOIS data issue to enhance domain trustworthiness and legitimacy.
  4. Publish a security policy and incident response contact information to improve incident management readiness and customer trust.
  5. Regularly audit third-party scripts and tracking tools to minimize security risks and ensure privacy compliance.

Technical notes

Notes

The website is built on a modern React and Next.js framework, leveraging server-side rendering and client-side interactivity. It uses asynchronous loading for analytics and cookie consent scripts to optimize performance. The site is mobile responsive with good SEO practices including meta tags and Open Graph data. Fonts are loaded from a CDN, and images are optimized with responsive sources. However, there is no detected CMS, and hosting provider details are not evident. Performance is moderate, with room for improvement in accessibility features and security header implementation. The technical infrastructure supports a professional user experience but requires enhancements in security and privacy technical controls.
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.
