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

Mount Street Neighbourhood is a luxury retail and cultural destination located in London’s Mayfair district, offering designer fashion, luxury beauty, dining, and cultural events. The website presents a polished and professional digital presence, leveraging Drupal 10 CMS and modern web technologies to deliver a rich user experience optimized for mobile and accessibility. The business targets affluent shoppers and tourists seeking high-end retail and dining experiences. However, the absence of WHOIS registration data raises concerns about domain legitimacy and ownership transparency. Security posture is generally good with HTTPS and no exposed sensitive data, but lacks explicit security policies and cookie consent mechanisms. Overall, the site is trustworthy and professional but would benefit from improved transparency and compliance documentation.

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. 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 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 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

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 website positions Mount Street Neighbourhood as a premier luxury retail and hospitality hub, supported by the Grosvenor parent company. It showcases a curated selection of high-end brands, restaurants, and cultural events, targeting a niche market of affluent consumers and visitors. The business model focuses on experiential retail and community engagement through events and exclusive offers. The partnership with Mayfair Club indicates a loyalty ecosystem. The site’s content and branding reflect a mature and consistent marketing strategy, though direct contact information is limited to a contact form, which may impact customer engagement. The lack of WHOIS data is a notable anomaly requiring further investigation.

Security posture

The website employs HTTPS and integrates Google Tag Manager and Mailchimp for analytics and marketing. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of security headers and published security or incident response policies limits the security maturity level. Cookie consent mechanisms are not evident, which may affect GDPR compliance. The site does not provide direct security contact channels such as security@ or abuse@ emails. Overall, the security posture is moderate but could be enhanced by implementing recommended headers, explicit privacy controls, and incident response information.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Add a clear cookie consent banner/mechanism to comply with GDPR and ePrivacy regulations.
  3. Publish a dedicated security policy and incident response contact information on the website.
  4. Verify and update WHOIS domain registration information to ensure transparency and trust.
  5. Regularly audit third-party scripts and marketing tools for security and privacy compliance.

Key observations

  2. Content is rich with images, events, and brand showcases.
  3. No direct company contact emails or phone numbers found; contact via form only.
  4. No explicit security or incident response policies published.
  5. Use of modern web technologies and CMS (Drupal 10).
  6. No WHOIS data available, which is a concern for domain legitimacy verification.
Technical notes

Notes

The website is built on Drupal 10 CMS, utilizing modern JavaScript libraries such as jQuery and Swiper.js for interactive content. Google Tag Manager is used for analytics and marketing integration, alongside Mailchimp for newsletter subscriptions. The site is mobile-optimized with responsive design and accessibility features such as skip links and ARIA attributes. Performance is moderate, with optimized images and lazy loading. No hosting provider information was detected. The technical implementation is solid but could benefit from enhanced security headers and privacy controls to reduce risk and improve compliance.
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.
