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

The website is professionally designed with clear navigation and a focus on user experience, targeting property buyers, renters, and investors. The technical infrastructure includes a custom CMS, modern JavaScript libraries, and integration with Google reCAPTCHA for form security. Privacy and cookie policies are comprehensive and GDPR compliant, with a consent mechanism implemented. Security posture is strong with HTTPS enforced and no visible vulnerabilities, though security headers could be improved. WHOIS data is unavailable, likely due to privacy protection, which is justified for this business type.

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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  2. 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';…

  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 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

  4. DNS health

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

    • High

      Domain Expires Soon

      Domain expires in 10 days

      What to do: Renew domain registration before expiration

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 strong market position as a large real estate consultancy in the USA, providing a broad range of property services and research publications. The business model centers on property brokerage and consultancy, targeting affluent buyers and investors. The website supports this with detailed property search capabilities and extensive market research content. The company maintains a global presence with multiple regional domains, indicating a broad partnership ecosystem. The lack of explicit contact emails or phone numbers on the site suggests a controlled communication channel via contact forms, enhancing lead management. The presence of social media links and app promotion indicates active marketing and customer engagement strategies.

Security posture

The website exhibits a solid security posture with HTTPS enforced and Google reCAPTCHA protecting contact forms against spam and abuse. Cookie consent is actively managed, supporting privacy compliance. However, the absence of explicit security headers like Content-Security-Policy and a lack of published incident response or vulnerability disclosure policies represent areas for improvement. No exposed sensitive data or vulnerable libraries were detected. The site does not currently provide a security.txt file or dedicated security contact channels, which could enhance transparency and incident handling readiness. Overall, the security maturity is good but could benefit from formalized policies and enhanced header configurations.

Recommendations

  1. Implement security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to strengthen browser security.
  2. Publish an incident response policy and provide dedicated security contact channels to improve transparency and readiness.
  3. Develop and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance accessibility features to meet compliance standards and improve user experience for all visitors.
  5. Regularly audit third-party scripts and dependencies to mitigate potential vulnerabilities and maintain security hygiene.

Technical notes

Notes

The website uses a custom CMS platform (KnightFrank.OneCms.America) with modern JavaScript libraries including jQuery UI Autocomplete and Slick Carousel for UI components. Google reCAPTCHA v2 invisible is integrated for form security. TagCommander and TrustCommander scripts are used for privacy and consent management. The site is mobile optimized with responsive design and preloads fonts for performance. Performance is moderate with room for optimization. SEO is supported by proper meta tags and canonical links. Accessibility is basic but could be improved. Hosting provider details are not explicitly found. Overall, the technical infrastructure is modern and supports the business needs effectively.
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.
