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

  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 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

      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

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

Hotel Troja operates in the hospitality sector, focusing on local clientele and event hosting in Prague. Its business model revolves around accommodation, dining, and event services, leveraging third-party booking platforms for reservations. The company maintains an active social media presence on Facebook and Instagram, enhancing customer engagement. The website content is professionally curated, supporting brand consistency and trust. No parent or subsidiary companies are identified. The business appears small-sized with a localized market position. The lack of WHOIS data is a limitation for external trust but does not detract from the operational legitimacy observed.

Security posture

The website employs HTTPS, ensuring encrypted communications. However, no security headers such as Content Security Policy or HSTS were detected, which could improve protection against common web attacks. No explicit security or incident response policies are published, indicating a potential gap in formal security governance. The use of third-party booking scripts introduces dependency risks that should be regularly audited. No vulnerabilities or exposed sensitive data were found in the HTML content. Overall, the security maturity is moderate but could benefit from enhanced headers, documented policies, and continuous monitoring.

Recommendations

  1. Implement standard security headers (CSP, HSTS, X-Frame-Options) to strengthen web security.
  2. Publish a dedicated security policy and incident response plan accessible to users.
  3. Regularly audit third-party scripts and booking integrations for vulnerabilities.
  4. Enhance website accessibility to meet WCAG guidelines for broader user inclusivity.
  5. Consider obtaining and publishing domain registration details to improve trust signals.

Technical notes

Notes

The website is built on a custom CMS platform (adSYSTEM) with jQuery and JavaScript libraries for UI interactions. The site loads CSS and JS resources from its own domain, with external booking services integrated asynchronously. Performance is moderate with responsive design for mobile devices. SEO is supported by appropriate meta tags and structured navigation. Accessibility is basic and could be improved. No advanced frameworks or platforms like React or Angular are detected. Hosting provider details are not disclosed. Overall, the technical implementation is stable but could be modernized with enhanced accessibility and security features.
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.
