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

Grand Hotel Praha is a well-established 4-star hospitality business located in the historic center of Prague, offering a range of accommodation options, dining, and event services. The website reflects a professional and consistent brand image with clear navigation and comprehensive service descriptions. The technical infrastructure leverages modern web technologies including Bootstrap, jQuery, and Google services, ensuring a responsive and interactive user experience. Security posture is solid with HTTPS enforced and cookie consent mechanisms in place, although some advanced security headers and policies could be improved. The absence of WHOIS data slightly impacts trust but the overall digital presence and contact transparency support legitimacy. Strategic recommendations include enhancing security headers, publishing incident response information, and improving accessibility 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

6 findings rated critical or high. Fix these first.

  1. 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"

    • 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';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

The hotel targets tourists and travelers seeking premium accommodation in Prague's Old Town, leveraging its unique location and historic ambiance as competitive advantages. The business model focuses on direct bookings through the official website, supported by ancillary services such as concierge, transfers, and event hosting. The presence of multiple related hospitality properties indicates a broader group or partnership network. Marketing efforts include retargeting and analytics tools, with GDPR-compliant cookie management. Growth potential lies in expanding digital engagement and enhancing security and privacy transparency to build further trust.

Security posture

The website demonstrates a mature security posture with HTTPS and cookie consent compliance. However, the lack of visible security headers like Content-Security-Policy and absence of published security policies or incident response contacts indicate areas for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of multiple third-party tracking and marketing scripts is managed with user consent, aligning with privacy regulations. Overall, the security culture appears adequate but could benefit from formalized policies and disclosures.

Recommendations

  1. Implement and enforce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a security policy and incident response contact information to improve transparency and readiness.
  3. Introduce a security.txt file to facilitate vulnerability disclosures.
  4. Enhance website accessibility to meet WCAG standards for broader user inclusivity.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy risks and improve performance.

Technical notes

Notes

The website uses a combination of jQuery, Bootstrap, and various plugins for UI components and interactivity, including date pickers, sliders, and fancybox galleries. Google Maps API integration provides location services. Analytics and marketing tools include Google Analytics, Facebook Pixel, and ZoomLetter popups. The site is mobile responsive with good SEO meta tags and Open Graph data. Performance is moderate, with some lazy loading implemented. No CMS is explicitly detected, suggesting a custom or proprietary platform. Hosting details are not evident from the HTML content. Opportunities exist to modernize JavaScript usage and optimize loading times further.
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.
