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

3 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. 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.

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  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

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 Belgium targets a mature real estate market with a focus on office, industrial, and residential sectors. Their business model centers on consultancy and brokerage services, leveraging global brand strength and local expertise. The company has a long-standing presence since 1973, indicating market experience and stability. The website supports multiple languages and regional offices, reflecting a broad geographic reach. Marketing and analytics tools are used moderately, balancing user experience with data collection. The absence of direct contact emails or phone numbers on the site suggests a preference for controlled lead capture via forms. The company maintains a strong digital footprint with active social media channels and regularly updated research publications, supporting thought leadership and client engagement.

Security posture

The website employs HTTPS with a valid SSL configuration, uses Google reCAPTCHA to protect contact forms, and avoids exposing sensitive data in the HTML. However, it lacks some recommended security headers such as Strict-Transport-Security and X-Frame-Options, which could mitigate certain attack vectors. No known vulnerabilities or outdated libraries were detected in the provided content. The absence of a published security policy or incident response contact limits transparency in security governance. Overall, the security posture is good but could be improved with enhanced header configurations and formalized security disclosures.

Recommendations

  1. Implement additional HTTP security headers including Strict-Transport-Security, X-Content-Type-Options, and X-Frame-Options to strengthen browser security.
  2. Publish a clear security policy and incident response contact information to improve transparency and trust.
  3. Consider adding a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  4. Enhance accessibility features to improve compliance with standards and user experience for all visitors.
  5. Regularly review and update third-party scripts and libraries to ensure no vulnerabilities are introduced.

Technical notes

Notes

The website is built on ASP.NET WebForms, indicating a mature but somewhat legacy technology stack. It integrates modern services such as Google reCAPTCHA for bot protection and TagCommander for consent and marketing management. Performance is moderate with some optimizations possible. The site is mobile responsive with good SEO practices including meta tags and structured navigation. Accessibility is basic and could be improved. Hosting provider details are not explicitly identified. The site uses multiple external domains for scripts and analytics, all reputable. Overall, the technical infrastructure supports a professional and secure user experience but could benefit from modernization and enhanced accessibility.
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.
