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

KHWS Limited is an established independent marketing agency based in London, operating since 1993. The company specializes in delivering marketing solutions that leverage data and behavioural science, partnering with Durham University Business School to develop proprietary insight tools known as Sales Triggers. Their services span brand marketing, channel marketing, and digital marketing, targeting brands seeking effective customer engagement strategies. The website reflects a professional and modern digital presence, utilizing React, Next.js, and Bootstrap frameworks, hosted likely on Render.com. Privacy compliance is robust, with Cookiebot managing cookie consent and a clear privacy policy in place. Security posture is good with HTTPS enforced and no visible vulnerabilities, though some security headers and policies could be improved. WHOIS data is unavailable due to domain naming restrictions, which introduces some uncertainty but the website's professionalism and content quality support legitimacy.

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. 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
    • 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

  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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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';…

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

KHWS holds a strong market position as a data-driven marketing agency with a unique approach integrating behavioural science. Their competitive advantage lies in proprietary methodologies and academic partnerships, enabling them to deliver differentiated marketing campaigns. The business model focuses on B2B marketing services with a medium-sized team and a portfolio of notable clients. Growth indicators include active case studies and testimonials. The partnership ecosystem includes Durham University and major brands like Samsung and Bacardi. The company maintains a transparent and compliant online presence, supporting trust and credibility.

Security posture

The website demonstrates a mature security posture with HTTPS enabled and cookie consent mechanisms aligned with GDPR. No critical vulnerabilities or exposed sensitive data were detected. However, the absence of explicit security policies, incident response contacts, and security headers suggests room for improvement. The lack of a security.txt file or vulnerability disclosure policy limits transparency for security researchers. Overall, the security maturity is good but could be enhanced by publishing formal policies and implementing additional HTTP security headers.

Recommendations

  1. Implement and publish a dedicated security policy and incident response page to improve transparency and preparedness.
  2. Add security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to strengthen web security.
  3. Create and host a security.txt file to facilitate responsible vulnerability disclosure.
  4. Regularly audit third-party scripts and libraries for vulnerabilities and update them promptly.
  5. Enhance accessibility features to improve compliance and user experience for all visitors.

Technical notes

Notes

The website is built on a modern technology stack including React, Next.js, and Bootstrap, ensuring responsive design and good user experience across devices. Hosting appears to be on Render.com, with assets served efficiently. SEO is well addressed with meta tags and structured data, although no JSON-LD schema was detected in the truncated HTML. Cookiebot is integrated for cookie management, and Google Tag Manager along with HubSpot analytics are used for tracking and marketing automation. Performance is moderate, with potential for optimization in loading speed and accessibility compliance. No CMS was explicitly detected, suggesting a custom or headless architecture.
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.
