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

5 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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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
    • 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

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

Kesslers London operates in the retail design sector, targeting retail brands and businesses seeking innovative in-store solutions. Their business model is B2B, focusing on creative design, technical engineering, manufacturing, project management, and installation services. The company leverages a strong partnership ecosystem, including a sister brand, to enhance its market offering. The website showcases key clients and brand logos, indicating established market presence and trust. Their digital marketing strategy includes social media engagement and tracking pixels for analytics and retargeting. The lack of visible privacy policy and WHOIS data suggests areas for improvement in transparency and compliance documentation. Growth indicators include a comprehensive service portfolio and a focus on evolving retail trends to increase shopper engagement and footfall.

Security posture

The website demonstrates a good security posture with HTTPS enabled and a GDPR-compliant cookie consent banner that allows users to customize preferences. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces the overall security hardening. No security.txt or incident response contact information is published, which limits the ability for external parties to report vulnerabilities responsibly. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The use of Google Tag Manager and third-party tracking pixels is managed but should be regularly audited for security risks. Overall, the site is secure for typical business use but could benefit from enhanced security policies and headers.

Recommendations

  1. Implement and verify comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to improve protection against common web attacks.
  2. Publish a clear and accessible privacy policy page detailing data collection, processing, and user rights to enhance GDPR compliance and user trust.
  3. Create and maintain a security.txt file to provide a formal channel for vulnerability disclosure and incident reporting.
  4. Add explicit security policy and incident response contact information on the website to improve transparency and readiness.
  5. Regularly audit third-party scripts and tracking pixels to ensure they are up to date and do not introduce vulnerabilities.

Technical notes

Notes

The website is built on WordPress CMS using the Elementor page builder, supported by plugins such as Rank Math SEO, Cookie Law Info, Jet Engine, and Unlimited Elements. It uses jQuery and Google Tag Manager for analytics and marketing integrations. The site is mobile optimized with responsive design and good accessibility features. Performance is moderate, with some large images and multiple scripts that could be optimized further. The technical stack is modern and well-maintained, but there is room for improvement in security header implementation and hosting transparency. No hosting provider information was found in the HTML content. Overall, the technical infrastructure supports a professional and user-friendly website experience.
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.
