SuperCOR · El Corte Inglés · Retail · Spain

Partial score · DNS & email only

59/100

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

SuperCOR is a supermarket brand operating under the El Corte Inglés retail group in Spain, offering a wide range of products including food, personal hygiene, and pet supplies. The website serves as a digital storefront providing product catalogs, store locators, and promotional information. Technically, the site uses modern web technologies such as Bootstrap, jQuery, and slick carousel, with integration of analytics and tracking tools like Google Tag Manager, Microsoft Clarity, and Facebook Pixel. The site is mobile optimized and presents a professional design with consistent branding. Security posture is adequate with HTTPS and cookie consent mechanisms, but lacks visible security headers and explicit privacy policy pages. WHOIS data is unavailable due to registry restrictions, but the domain appears legitimate and consistent with the business identity. Overall, the site is trustworthy and well-positioned in the retail market, though improvements in privacy transparency and security headers are recommended.

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. GDPR outside view

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

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, Twitter, Cloudflare

      What to do: Document all third-party data sharing in your privacy policy

  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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

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

  • Security headers: did not complete in this scan.
  • 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

SuperCOR targets general consumers in Spain seeking convenient supermarket shopping with quality assurance from a reputable parent company, El Corte Inglés. The business model focuses on physical stores complemented by digital catalogs and online promotions. The brand leverages its parent company's reputation to maintain market position and customer trust. The presence of social media channels and digital marketing tools indicates active customer engagement and modern retail practices. The lack of detailed WHOIS data is a limitation but not unusual for .es domains. The company could enhance customer trust by publishing comprehensive privacy and security policies.

Security posture

The website enforces HTTPS and uses a cookie consent banner compliant with GDPR principles, indicating awareness of privacy regulations. However, the absence of explicit privacy policy and terms of service pages reduces transparency. No security headers were detected in the provided data, which could expose the site to certain web-based attacks. The use of multiple third-party scripts introduces potential risk vectors that require regular auditing. No vulnerabilities or exposed sensitive data were found in the HTML content. Incident response contacts and security policies are not publicly visible, which is a gap in security readiness. Overall, the security posture is moderate but can be improved with better policy disclosures and technical hardening.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service pages accessible from the homepage.
  2. Implement standard security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Provide clear contact information for security incidents and abuse reporting.
  4. Regularly audit and update third-party scripts to mitigate vulnerabilities.
  5. Enhance accessibility features and conduct periodic security assessments.

Technical notes

Notes

The website is built on a modern tech stack including Bootstrap for responsive design, jQuery for DOM manipulation, and slick carousel for image sliders. It integrates third-party analytics and marketing tools such as Google Tag Manager, Microsoft Clarity, and Facebook Pixel. Hosting appears to be managed internally by El Corte Inglés via the eci.contebio.com domain. Performance is moderate with good mobile optimization and SEO meta tags present. Accessibility is basic and could be improved. The site uses OneTrust for cookie consent management, indicating compliance efforts. No CMS was explicitly detected. Overall, the technical infrastructure supports a professional retail website but could benefit from enhanced accessibility and security features.
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.
