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

P. de Jager & Sons Limited is a well-established UK-based supplier of top quality flower bulbs, with a history dating back to 1868. The company operates an e-commerce platform offering a wide range of bulbs including tulips, daffodils, crocus, hyacinth, and allium varieties. The business holds prestigious royal warrants, underscoring its trusted market position and commitment to quality. Their website is professionally designed, mobile-optimized, and provides comprehensive product information and customer engagement features such as newsletters and catalog downloads. Technically, the website leverages modern JavaScript libraries and frameworks including Alpine.js, HTMX, and Swiper.js, supported by a specialized e-commerce platform (KhooSeller). The site integrates multiple analytics and marketing tools such as Google Analytics, Klaviyo, and Google Ads, with appropriate cookie consent mechanisms in place. Security best practices are observed with HTTPS enforcement, CSRF tokens, and no visible sensitive data exposure, although some security headers could be more explicitly defined. The security posture is solid with no evident vulnerabilities or malicious content. However, the absence of WHOIS data limits domain trust verification, and no public vulnerability disclosure or incident response policies are found. Overall, the website presents a low risk profile with strong business credibility and good privacy compliance. Strategic recommendations include enhancing security header implementation, publishing a vulnerability disclosure policy, and improving incident response contact visibility to further strengthen trust and compliance.

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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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

The company holds a strong market position as a trusted supplier of flower bulbs in the UK, supported by its long history and royal warrants. Its business model combines retail and wholesale e-commerce, targeting gardeners and horticultural professionals. The website's comprehensive product catalog and customer engagement tools indicate a mature digital presence. Partnerships with platform providers and marketing services support operational efficiency. The company appears to maintain consistent branding and high content quality, reinforcing customer trust and satisfaction.

Security posture

The website demonstrates a mature security posture with HTTPS, CSRF protection, and cookie consent mechanisms. Use of modern libraries and deferred script loading enhances security and performance. However, explicit security headers like Referrer-Policy and Permissions-Policy are not clearly present. The lack of a public vulnerability disclosure policy and incident response contacts represents a compliance gap. No vulnerabilities or exposed sensitive data were detected in the analysis. Overall, security practices are good but could be improved with formal policies and header enhancements.

Recommendations

  1. Implement explicit security headers such as Referrer-Policy and Permissions-Policy to enhance browser security.
  2. Publish a public vulnerability disclosure policy to encourage responsible reporting and improve security transparency.
  3. Add clear incident response contact information, including security@ or abuse@ email addresses, to facilitate timely communication.
  4. Regularly audit and update third-party libraries to mitigate risks from vulnerabilities.
  5. Consider publishing a security.txt file to align with industry best practices and improve security posture.

Technical notes

Notes

The website is built on a modern tech stack including Alpine.js, HTMX, jQuery, and Swiper.js, integrated within the KhooSeller e-commerce platform. It uses deferred and async script loading to optimize performance. The site is mobile-optimized and accessible, with good SEO practices including meta tags and structured data (JSON-LD). Analytics and marketing tools are well integrated. Performance is moderate, with potential for improvement through further optimization. The lack of explicit hosting provider information limits full infrastructure assessment.
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.
