Risk levelMedium

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

ATLANTIC Hotels operates a regional chain of conference and wellness hotels primarily in Germany and Austria, targeting business travelers and wellness tourists. Their website is built on TYPO3 CMS and integrates modern consent management via Cookiebot and analytics through Google Analytics with opt-out capabilities. The site presents a professional design with good navigation and mobile optimization, supporting a medium-sized hospitality business model. However, the absence of explicit privacy policy and terms of service pages limits full compliance transparency. Technically, the site uses some outdated libraries such as jQuery 1.11.3, which may pose security risks if not updated. Security posture is generally good with HTTPS enforced and cookie consent mechanisms in place, but lacks visible security headers and published security policies. Overall, the website is accessible without WAF or blocking, linking to multiple external domains related to analytics and booking services.

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 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. 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

  3. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Unregistered MX Record

      MX record points to unregistered domain: mx01.reservision.com

      What to do: Remove or fix MX record pointing to unregistered domain

      • RFC 5321 §5.1
      • NIS2 21(2)(i)
      • IR 2024/2690 12.4: Implementing Regulation (EU) 2024/2690, Annex point 12.4: Asset inventory
      • NIST CM-8: NIST SP 800-53 Rev. 5 CM-8: System Component Inventory

      Unregistered MX Record

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.

Business context

Business profile

ATLANTIC Hotels holds a stable market position as a medium-sized hospitality provider with over 15 hotels in Germany and Austria. Their business model focuses on full-service hotel bookings for conferences and wellness, appealing to corporate and leisure segments. The website's integration with booking and analytics platforms indicates a mature digital presence. However, the lack of visible contact information and legal pages may impact customer trust and regulatory compliance. The company leverages partnerships with service providers like Cookiebot and Google for consent and analytics, but no direct partner or subsidiary domains were identified. Growth potential exists through enhanced transparency and security improvements.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and cookie consent management via Cookiebot. Google Analytics opt-out functionality is implemented, reflecting privacy awareness. However, the use of an outdated jQuery version (1.11.3) introduces potential vulnerabilities. No explicit security headers were detected, and no published security or incident response policies were found. The absence of a vulnerability disclosure or security.txt file limits transparency for security researchers. Overall, the site follows basic security best practices but would benefit from updating libraries, adding security headers, and publishing security policies to improve resilience and compliance.

Recommendations

  1. Update jQuery and other JavaScript libraries to current secure versions to mitigate known vulnerabilities.
  2. Publish a comprehensive privacy policy and terms of service pages to enhance legal compliance and user trust.
  3. Implement and publish security policies including incident response and vulnerability disclosure information.
  4. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to improve protection against common web attacks.
  5. Enhance contact information visibility including official company emails and phone numbers to improve business credibility.

Technical notes

Notes

The website is built on TYPO3 CMS, a robust open-source content management system, with jQuery 1.11.3 as the primary JavaScript library, which is outdated and should be upgraded. Google Tag Manager and Cookiebot scripts are integrated for analytics and cookie consent management respectively. The site uses Google Maps API for location services. Hosting appears to be managed via plutex.de nameservers. Performance is moderate with preloaded fonts and responsive design elements. SEO is supported by meta tags and hreflang attributes for German and English languages. Accessibility is basic with some ARIA roles and language attributes present. Technical debt is indicated by legacy jQuery and lack of modern security headers. Opportunities exist for modernization and enhanced security hardening.
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.
