Risk levelLow

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

Greencore is a leading UK-based producer of convenience foods, with a strong market position and a focus on sustainability, investor relations, and career development. The website reflects a mature business with comprehensive corporate information and multimedia content. Technically, the site is built on WordPress with modern analytics and marketing tools, showing good digital maturity. Security posture is solid with HTTPS and cookie consent mechanisms, though some security headers could be improved. The WHOIS data is unavailable, which slightly reduces trust but the overall professional presentation and business information support legitimacy. The site is accessible without WAF blocking or challenges.

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

2 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

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

Greencore operates in the manufacturing and retail sectors, focusing on convenience food production. It maintains a transparent investor relations section and actively promotes sustainability and inclusion. The business model centers on large-scale food manufacturing with subsidiaries such as Bakkavor. The company targets consumers, investors, and potential employees, leveraging a strong partnership ecosystem and digital presence. Growth indicators include recent news updates and sustainability reporting. The website supports recruitment and investor engagement effectively.

Security posture

The website employs HTTPS and Cloudflare bot management, with a cookie consent banner compliant with GDPR. Analytics tools include Google Analytics and Microsoft Clarity, indicating moderate user tracking. Security headers are not fully evident and could be enhanced. No critical vulnerabilities or exposed sensitive data were detected. Incident response and security policy information are not publicly available, suggesting room for improvement in transparency. Overall, the security posture is good but could benefit from additional hardening and disclosure.

Recommendations

  1. Implement comprehensive security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a clear security policy and incident response contact information to improve transparency and trust.
  3. Regularly audit third-party scripts and analytics tools to minimize potential vulnerabilities and privacy risks.
  4. Enhance privacy policy visibility and detail to fully comply with GDPR and other regulations.
  5. Consider publishing vulnerability disclosure and data protection officer contact details to demonstrate commitment to security and privacy.

Technical notes

Notes

The website is built on WordPress CMS with Yoast SEO plugin, Google Tag Manager, and analytics services like Google Analytics and Microsoft Clarity. It uses AWS and Cloudflare services for hosting and security. The site is mobile-optimized with good accessibility and SEO practices. Performance is moderate, with room for optimization. The technical stack is modern and well-integrated, supporting a professional corporate presence. No major technical debt or risks were identified, but security header implementation could be improved.
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.
