Security score

78/100

Risk levelLow

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

OTTO is a major German e-commerce company specializing in fashion, furniture, and technology products. The website presents a professional and comprehensive online shopping platform targeting general consumers in Germany. It offers various services such as installment purchases, purchase on account, old device take-back, and assembly services, positioning itself as a large enterprise in the retail sector. The technical infrastructure leverages modern JavaScript modules, Akamai CDN for hosting, and OneTrust for cookie consent management, indicating a mature digital presence with good performance and mobile optimization. Security posture is solid with HTTPS and cookie consent, but lacks explicit security policies and vulnerability disclosures. Overall, the website is trustworthy and professionally maintained, though improvements in transparency around privacy and security policies 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

2 findings rated critical or high. Fix these first.

  1. 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  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 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

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

OTTO holds a strong market position as a leading online retailer in Germany with a broad product range and well-established brand recognition. Its business model focuses on direct-to-consumer e-commerce with additional services enhancing customer convenience. The company targets a wide demographic, primarily general consumers interested in fashion, home furnishings, and technology. The website's extensive navigation and curated categories reflect a sophisticated marketing and product management strategy. While no explicit partnerships or subsidiaries were identified in the provided data, the use of Akamai CDN and OneTrust indicates collaboration with reputable service providers. The absence of detailed company registration or VAT information on the site suggests that such details may be located elsewhere or require deeper inspection.

Security posture

The website demonstrates a good security baseline with enforced HTTPS and cookie consent mechanisms. However, it lacks visible security headers and published security policies or incident response contacts, which are important for transparency and trust. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The absence of a security.txt file or vulnerability disclosure page limits the ability for external security researchers to report issues responsibly. Overall, the security posture is adequate for a large e-commerce platform but could be enhanced by adopting additional best practices and publishing relevant policies.

Recommendations

  1. Publish a clear and accessible privacy policy and terms of service on the website.
  2. Implement and publish a security policy and incident response contact information.
  3. Add standard security headers such as Content-Security-Policy and X-Frame-Options.
  4. Provide a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Enhance privacy compliance transparency by detailing data retention and processing practices.

Technical notes

Notes

The website uses a modern tech stack with ES modules, custom frontend components, and polyfills for compatibility. Hosting is via Akamai CDN, ensuring fast content delivery and scalability. The site is well-optimized for mobile devices and accessibility, with good SEO practices evident from meta tags and structured navigation. No common CMS was detected, suggesting a custom or proprietary platform. Performance is likely fast due to CDN usage and efficient resource loading. Technical risks are minimal, but the lack of explicit security headers and published policies represents an area for improvement to reduce potential attack surfaces and increase user trust.
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.
