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

Knight Frank is a globally recognized independent real estate consultancy founded in 1896 and headquartered in London, UK. The company offers a broad range of residential and commercial property services including sales, lettings, investment advisory, occupier strategy, and valuations. With nearly 500 offices worldwide, Knight Frank serves a diverse international clientele seeking property solutions. The website reflects a mature digital presence with comprehensive content, professional design, and clear navigation, supporting their market leadership. Technically, the site is built on ASP.NET with modern front-end libraries and includes security features such as HTTPS and Google reCAPTCHA to protect user interactions. Privacy and cookie policies are well implemented with consent mechanisms, indicating good compliance with GDPR and related regulations. However, the WHOIS data for the domain is unavailable, which is inconsistent with the company's long history but may be due to privacy protection or query limitations. Overall, the website demonstrates a strong security posture and business credibility with minor recommendations for enhanced security headers and accessibility improvements.

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

2 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 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

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 holds a leading position in the global real estate market, leveraging a vast international office network and a diversified service portfolio. Their business model focuses on consultancy and brokerage services for high-value residential and commercial properties, targeting investors, occupiers, and private clients. The company emphasizes research and insights, publishing flagship reports and maintaining a strong content marketing strategy. Partnerships such as fund management (kf-im.com) complement their offerings. The brand's longevity and global footprint provide competitive advantages, while their digital infrastructure supports client engagement and lead generation. The absence of detailed WHOIS data is a minor anomaly but does not detract from their established market presence.

Security posture

The website employs HTTPS with a good SSL configuration and integrates Google reCAPTCHA to mitigate spam and automated abuse on contact forms. Security headers are partially implemented but could be improved by adding Content-Security-Policy and X-Content-Type-Options headers. No exposed sensitive data or vulnerable libraries were detected in the HTML content. Privacy and cookie consent mechanisms are robust, supporting GDPR compliance. Incident response contact is provided via a dedicated email for cyber fraud protection. Overall, the security posture is strong for a commercial real estate website, with room for enhancement in HTTP header policies and accessibility.

Recommendations

  1. Implement a Content-Security-Policy header to reduce risk of cross-site scripting and data injection.
  2. Add X-Content-Type-Options header to prevent MIME-sniffing vulnerabilities.
  3. Enhance website accessibility features to improve compliance with WCAG standards.
  4. Regularly audit third-party scripts and dependencies for security vulnerabilities.
  5. Consider publishing a formal security policy and vulnerability disclosure program to increase transparency.

Technical notes

Notes

The website is built on ASP.NET Web Forms with a custom CMS platform (KnightFrank.OneCms.Europe). It uses modern front-end libraries such as jQuery, Slick Carousel, and Google reCAPTCHA. The site loads multiple custom fonts and icons, and integrates TagCommander for marketing tag management. Performance is moderate with good mobile optimization and SEO practices including meta tags and structured navigation. Accessibility is basic and could be improved. Hosting provider details are not explicitly identified. The technical stack is mature and stable, supporting a large enterprise-level real estate consultancy with global reach.
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.
