Security report for colruyt.be

Colruyt · Retail · Belgium

Low risk. 2 critical or high findings in GDPR outside view and SSL/TLS.

Security score

83/100

Risk levelLow

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

Colruyt is a leading Belgian retail supermarket chain focused on offering the lowest prices for a wide range of products. The website serves as a digital storefront providing product information, promotions, recipes, and store locators primarily targeting Dutch-speaking customers in Belgium and Luxembourg. The site is built on modern web technologies including Vue.js and Adobe Experience Manager, with performance and mobile optimization considered good. Security posture is strong with HTTPS enforced and monitoring via Dynatrace, though explicit security headers and public security policies are absent. Privacy compliance is partially addressed with a cookie consent mechanism but lacks a clearly accessible privacy policy. WHOIS data is restricted by the .be registry, which is common but reduces transparency. Overall, the website is professional, trustworthy, and well-positioned in the retail market.

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. GDPR outside view

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

    • 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

  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

      SSL Certificate Expires Soon

      SSL certificate expires in 26 days

      What to do: Renew SSL certificate before expiration

      • NIS2 21(2)(h)
      • IR 2024/2690 9.2(c): Implementing Regulation (EU) 2024/2690, Annex point 9.2(c): Cryptography
      • NIST SC-17: NIST SP 800-53 Rev. 5 SC-17: Public Key Infrastructure Certificates

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

Colruyt operates in the retail sector with a strong emphasis on price competitiveness and customer engagement through promotions and recipes. The business model is centered on supermarket sales supported by digital tools for customer convenience. The company maintains a consistent brand presence and leverages a parent company domain (colruytgroup.com) for broader corporate functions. The website's technical infrastructure indicates a mature digital presence with integration of tag management and monitoring services. Growth indicators include extensive product offerings and localized content. Partnerships appear limited to internal group domains and standard third-party services for fonts and cookie management.

Security posture

The website demonstrates a solid security foundation with HTTPS and cookie security attributes set to SameSite=Lax. Use of Dynatrace for real user monitoring indicates proactive performance and security monitoring. However, the absence of explicit security headers such as Content-Security-Policy and X-Frame-Options is a gap. No public security or incident response policies were found, limiting transparency for security incident handling. The lack of a vulnerability disclosure program or security.txt file suggests room for improvement in security communication. No vulnerabilities or exposed sensitive data were detected in the analyzed content.

Recommendations

  1. Publish a comprehensive privacy policy accessible from the homepage to improve GDPR compliance and user trust.
  2. Implement and publish security policies including incident response and vulnerability disclosure to enhance transparency.
  3. Add standard security headers (CSP, X-Frame-Options, HSTS) to strengthen defense against common web attacks.
  4. Provide clear and verified contact information including support emails and phone numbers to improve business credibility.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are included.

Technical notes

Notes

The website uses Adobe Experience Manager as CMS, Vue.js for frontend interactivity, and integrates Dynatrace for monitoring. Fonts are loaded from Google Fonts and Adobe Typekit. Cookie consent is managed via cookielaw.org scripts. The site is mobile optimized with responsive design and preconnect hints for performance. No major technical debt or deprecated technologies were detected. Performance is moderate with room for optimization in loading scripts asynchronously and reducing third-party dependencies. Accessibility features are basic but present. SEO is supported by meta tags, canonical links, and Open Graph metadata.
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.
