The Athenaeum Hotel & Residences is a luxury 5-star hotel located in the heart of Mayfair, London, offering upscale accommodation, dining, spa, and event services. The website reflects a well-established hospitality business with a rich history dating back to 1850, targeting affluent travelers, families, and long-stay guests. The site features a professional design, clear navigation, and integrated booking systems, enhancing user experience and business operations. Technically, the website utilizes modern frameworks and libraries including Umbraco CMS, Bootstrap, and various analytics and tracking tools such as Google Analytics, Hotjar, and Microsoft Clarity, indicating a mature digital infrastructure. Security posture is strong with HTTPS enforcement and security headers, though explicit security policies and incident response information are not publicly visible. Privacy compliance is partially addressed with privacy and cookie policies and consent mechanisms, but could be improved with clearer GDPR indicators and data retention disclosures.

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. 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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

  2. GDPR outside view

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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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. 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

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 Athenaeum Hotel & Residences positions itself as a premium luxury hospitality provider in central London, leveraging its historic legacy and prime location opposite Green Park. Its business model focuses on high-end accommodation including hotel rooms, suites, and private residences, complemented by dining, spa, and event hosting services. The company targets discerning travelers seeking exclusivity and personalized service. The website's integration with third-party booking platforms and extensive use of analytics tools suggests a data-driven approach to customer engagement and revenue optimization. The presence of multiple offers and seasonal promotions indicates active marketing strategies. The lack of visible WHOIS data is unusual for a hospitality business and may warrant further verification. No direct partnerships or subsidiaries are identified from the website content.

Security posture

The website demonstrates a solid security foundation with HTTPS enabled and multiple security headers implemented, reducing common web vulnerabilities. Booking forms appear secure and no sensitive data is exposed in the HTML. However, the absence of a published security policy, incident response plan, or vulnerability disclosure program limits transparency and preparedness perception. Extensive use of third-party scripts and tracking pixels introduces potential risk vectors that require ongoing monitoring. Privacy compliance is partially addressed but could be enhanced with clearer GDPR compliance statements and data protection officer contact details. Overall, the security posture is good but could benefit from improved policy disclosures and formalized incident response communication.

Recommendations

  1. Publish a dedicated security policy and incident response information page to improve transparency and trust.
  2. Implement a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  3. Regularly audit and update third-party scripts and tracking tools to mitigate potential vulnerabilities.
  4. Enhance privacy compliance by clearly stating GDPR adherence, data retention policies, and providing DPO contact information if applicable.
  5. Verify and publish domain registration details to improve legitimacy and reduce concerns related to WHOIS data absence.

Technical notes

Notes

The website is built on the Umbraco CMS platform, utilizing Bootstrap for responsive design and Tiny Slider for carousels. It integrates multiple analytics and tracking services including Google Analytics, Microsoft Clarity, Hotjar, Quantcast, and SessionCam, indicating a comprehensive approach to user behavior analysis. The site loads multimedia content such as Vimeo videos and uses FontAwesome for icons. Performance is moderate with good mobile optimization and accessibility features. The presence of multiple Google Tag Manager containers and third-party widgets suggests complexity that requires careful management to avoid performance degradation or security risks. No hosting provider information was directly identified from the HTML content.
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.
