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

Knight Frank is a well-established UK-based real estate company specializing in residential and luxury property sales and lettings, with a global presence spanning over 50 countries. The website reflects a mature digital infrastructure using modern technologies such as EPiServer CMS, JavaScript ES modules, and Azure Application Insights for analytics. The site is professionally designed, mobile-optimized, and provides comprehensive property search and service information. Security posture is strong with HTTPS enforcement and security headers, though explicit security policies and incident response contacts are not published. Privacy and cookie policies are present with consent mechanisms, indicating good compliance with GDPR. Overall, the site is trustworthy and professionally maintained, though WHOIS data for the 'www' subdomain is unavailable due to domain naming rules, which does not impact the legitimacy of the main domain.

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

1 finding 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

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

Knight Frank operates in the real estate sector, targeting property buyers, sellers, landlords, and tenants primarily in the UK but also worldwide. Their business model includes property sales, lettings, valuations, advisory, and specialist consultancies such as rural and interior design services. The company leverages a global network of offices and partners, enhancing market reach and customer service. The website's content and navigation support a high level of user engagement and conversion potential. The presence of multiple country-specific domains indicates a strong international strategy. Knight Frank's long history since 1896 and consistent branding reinforce its market position as a trusted estate agent.

Security posture

The website demonstrates a solid security posture with HTTPS enabled and multiple security headers implemented, reducing common web vulnerabilities. Use of Google reCAPTCHA on forms helps mitigate automated abuse. However, the absence of published security policies, incident response procedures, and vulnerability disclosure mechanisms suggests room for improvement in transparency and readiness. No vulnerabilities or exposed sensitive data were detected in the HTML content. The security score is high but could be enhanced by publishing explicit security documentation and providing direct security contact channels.

Recommendations

  1. Publish a dedicated security policy and incident response page to improve transparency and user trust.
  2. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Provide direct security contact emails (e.g., security@knightfrank.co.uk) for incident reporting.
  4. Regularly review and audit third-party scripts and dependencies to mitigate supply chain risks.
  5. Enhance data retention and privacy policy details to further strengthen GDPR compliance.

Technical notes

Notes

The website is built on the EPiServer CMS platform, utilizing modern JavaScript ES modules and libraries such as Swiper.js for UI components. It integrates Azure Application Insights for telemetry and Google reCAPTCHA for bot protection. The site is mobile-optimized with responsive design and accessibility considerations. Performance is moderate, with preloading of fonts and assets to improve load times. The technical stack is modern and well-maintained, though hosting provider details are not explicitly identified. Opportunities exist to optimize performance further and enhance security transparency.
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.
