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

5 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 X-Frame-Options header

      Prevents clickjacking attacks

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

  2. GDPR outside view

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

    • 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

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, Twitter

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

  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

  4. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • 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

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 holds a strong market position as one of the largest congress hotels in northern Moravia, leveraging its affiliation with CPI Hotels and Choice Privileges loyalty program. Its business model focuses on hospitality services including accommodation, wellness, and event hosting. The presence of special offers and gift vouchers indicates active marketing and customer engagement. The company maintains partnerships for ethics and whistleblowing, enhancing corporate governance. The website's external links and social media presence support a broad customer outreach and brand visibility.

Security posture

The website enforces HTTPS and implements cookie consent mechanisms aligned with GDPR. Forms include validation and anti-spam features. However, the lack of visible security headers such as Content-Security-Policy and absence of a dedicated security policy or vulnerability disclosure page are gaps. Incident response contact channels are indirect via whistleblowing and ethics hotlines but no direct security contact is provided. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the security posture is good but could be improved with explicit policies and headers.

Recommendations

  1. Implement and publish a dedicated security policy page outlining security practices and incident response.
  2. Add security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection.
  3. Establish and publicize a vulnerability disclosure program, possibly via security.txt.
  4. Verify and update WHOIS domain registration information to ensure transparency and trust.
  5. Regularly audit third-party scripts and tracking tools for security and privacy compliance.

Technical notes

Notes

The website uses modern web technologies including JavaScript frameworks, CSS, and HTML5 with lazy loading and responsive images for performance optimization. Analytics and marketing tools such as Google Analytics, Google Tag Manager, Sojern, and Dialogshift Webchat SDK are integrated. Cookie consent is managed via Cookies Giant. The site shows good mobile optimization and accessibility features. No CMS was explicitly detected, suggesting a custom or proprietary platform. Performance is moderate with room for improvement in loading speed and security header implementation.
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.
