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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  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 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

  3. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Unregistered MX Record

      MX record points to unregistered domain: smtp.metro.info

      What to do: Remove or fix MX record pointing to unregistered domain

      • RFC 5321 §5.1
      • NIS2 21(2)(i)
      • IR 2024/2690 12.4: Implementing Regulation (EU) 2024/2690, Annex point 12.4: Asset inventory
      • NIST CM-8: NIST SP 800-53 Rev. 5 CM-8: System Component Inventory

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

METRO AG's market positioning as a wholesale leader in the food service distribution sector is supported by its extensive network of subsidiaries and partner sites, including MAKRO Spain and its corporate magazine MPULSE. The business model focuses on serving the HoReCa segment and traders with a combination of physical stores and digital delivery channels. The company demonstrates strong compliance and governance frameworks, with detailed information on corporate governance, compliance programs, and data protection officers. The website's content and structure indicate a focus on transparency, investor relations, and corporate responsibility, which are critical for maintaining stakeholder trust and regulatory compliance in the retail sector.

Security posture

The website exhibits a mature security posture with HTTPS enforced and multiple security headers likely in place. Cookie consent is managed via a detailed banner with granular categories, supporting GDPR compliance. The use of request verification tokens in cookies indicates protection against CSRF attacks. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of explicit incident response contacts and vulnerability disclosure policies suggests areas for improvement in security transparency and readiness. Overall, the security measures align well with industry best practices for corporate websites.

Recommendations

  1. Publish explicit incident response and security contact information to improve transparency and readiness.
  2. Implement and publish a vulnerability disclosure policy and security.txt file to encourage responsible reporting.
  3. Regularly audit and update third-party scripts and analytics tools to mitigate potential vulnerabilities.
  4. Enhance security headers by explicitly defining Content-Security-Policy and other advanced headers if not already done.
  5. Maintain and regularly review cookie consent mechanisms to ensure ongoing GDPR compliance.

Technical notes

Notes

The website is built on a modern technology stack including ASP.NET framework, Bootstrap 4.5 for responsive design, and JavaScript libraries such as Swiper.js for interactive elements. It integrates Google Tag Manager and Google Analytics for tracking, alongside Siteimprove Analytics for quality assurance. Hosting is provided via Akamai, a reputable CDN and security provider, enhancing performance and availability. The site demonstrates good mobile optimization and accessibility features, with structured navigation and SEO-friendly metadata. Performance is moderate, with potential for optimization in image loading and script deferral. The technical infrastructure supports a professional corporate web presence suitable for a large enterprise.
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.
