Security score

45/100

Risk levelHigh

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

The website rewe-group.com is currently inaccessible due to a Cloudflare Web Application Firewall (WAF) block, which prevents access to any meaningful content. This blockage indicates that the site is actively protected against online attacks but also restricts external analysis. The domain is mature, registered since 2005, and shows professional DNS and email configurations, suggesting a legitimate business presence likely in the retail sector. However, the lack of a valid SSL certificate and absence of HTTPS severely impacts the security posture and trustworthiness of the site. No privacy, cookie, or terms of service policies are detectable, and no contact information is available on the accessible page, limiting compliance and user trust assessment. The technical infrastructure relies on Cloudflare for security and hosting, but critical security best practices such as TLS enablement and HSTS are missing. Overall, the site’s security posture is weak due to missing HTTPS and blocked content, resulting in a low AI score and incomplete analysis.

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

8 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

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • 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

  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

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. 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';…

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

Based on the domain and DNS data, rewe-group.com is associated with a large retail entity, likely the REWE Group, a known European retail conglomerate. The domain age and registration details support a stable and established business. The lack of accessible content prevents detailed insights into business model, services, or market positioning. The domain uses professional email hosting and Google domain name servers, indicating a well-managed IT infrastructure. No direct partnerships or subsidiaries are identifiable from the accessible data. The business likely targets retail consumers and operates at an enterprise scale given the domain maturity and DNS setup.

Security posture

The current security posture is poor due to the absence of a valid SSL certificate and HTTPS support, which is a critical vulnerability for any modern website. The presence of security headers like X-Frame-Options and Referrer-Policy is positive but insufficient without HTTPS. The Cloudflare WAF is actively blocking access, indicating a proactive security stance but also limiting transparency. No vulnerabilities such as Heartbleed or POODLE are detected, but the lack of TLS protocols and HSTS reduces protection against interception and downgrade attacks. No incident response or security policy information is publicly available, and no vulnerability disclosure or security.txt files are found. Overall, the site needs urgent improvements in SSL/TLS configuration and transparency to enhance trust and compliance.

Recommendations

  1. Install and maintain a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Enable modern TLS protocols (TLS 1.2 or TLS 1.3) and disable legacy protocols.
  3. Implement HTTP Strict Transport Security (HSTS) with includeSubDomains and preload directives.
  4. Publish clear privacy, cookie, and terms of service policies accessible to users.
  5. Provide visible and verified contact information including support and security contacts.
  6. Consider publishing a security policy and vulnerability disclosure program to improve transparency.
  7. Enable DNSSEC and CAA records to enhance DNS security and certificate issuance control.
  8. Review and optimize Cloudflare WAF rules to reduce false positives and improve user access.
Technical notes

Notes

The website is hosted behind Cloudflare, which provides CDN and security services. DNS records are professionally managed with Google Cloud DNS and hosted email services. However, the SSL certificate is missing or invalid, and no TLS protocols are enabled, which is a critical technical deficiency. The HTTP headers include some security controls but lack comprehensive coverage. The site currently serves a Cloudflare block page with minimal HTML content, no metadata, no forms, no scripts beyond Cloudflare challenge scripts, and no visible business or marketing content. Performance metrics are unavailable due to blocked content. The technical stack is minimal and focused on security enforcement rather than content delivery. There is an opportunity to modernize the SSL/TLS configuration and improve content delivery and SEO once access is restored.
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.
