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

4 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

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, Google APIs

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

  2. 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

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 business operates in the hospitality sector with a focus on wellness and congress services, positioning itself as a regional hotel near a popular recreational area. The business model centers on direct bookings through its website, offering packages and gift vouchers to enhance customer engagement. The presence of social media channels and professional branding indicates active marketing efforts. The lack of WHOIS data suggests a need for domain registration verification to strengthen credibility. The company targets both leisure and business customers, leveraging its location and facilities to attract a diverse clientele.

Security posture

The website demonstrates a mature security posture with HTTPS and cookie consent compliance. However, no explicit security headers were detected, and there is no published security or incident response policy, which are areas for improvement. No vulnerabilities or exposed sensitive data were found in the HTML content. The use of third-party analytics and retargeting scripts is balanced with user consent mechanisms, aligning with GDPR requirements. The absence of WHOIS data is a concern for domain legitimacy and should be addressed to improve trustworthiness.

Recommendations

  1. Implement and configure HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-XSS-Protection.
  2. Publish a clear security policy and incident response information on the website to enhance transparency and preparedness.
  3. Verify and update WHOIS domain registration information to ensure public availability and trust.
  4. Regularly audit third-party scripts and dependencies to mitigate potential vulnerabilities.
  5. Enhance accessibility features to improve compliance and user experience for all visitors.

Technical notes

Notes

The website uses a modern tech stack including vanilla JavaScript, Google Tag Manager, Google Analytics, Facebook Pixel, and a third-party booking engine (Bookolo). It loads fonts from Typekit and Google Fonts and uses a vanilla JS datepicker. The site is mobile optimized with responsive images and a clear navigation structure. Performance is moderate with asynchronous loading of analytics scripts. No CMS was detected, suggesting a custom or static site architecture. Hosting provider details are not disclosed. The site could benefit from improved accessibility and SEO metadata 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.
