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

5 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 Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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. 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"

  3. 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's market position as a leading e-commerce and retail platform is supported by its extensive partner network and product catalog. The business model includes direct retail and marketplace services (OTTO Market), supplemented by advertising offerings (OTTO Advertising). The company targets a broad consumer base and business partners, emphasizing sustainability and digital responsibility. The corporate site supports brand trust through compliance information and active social media engagement. The presence of a dedicated compliance page and external corporate group site indicates strong governance. The company leverages partnerships and digital marketing tools to maintain competitive advantage and growth.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, CSRF protection, and a cookie consent mechanism aligned with GDPR. However, explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options are not evident in the HTML content, representing an area for improvement. No exposed sensitive data or vulnerable libraries were detected. Incident response contact information and vulnerability disclosure mechanisms are not publicly available, which could be enhanced to improve security transparency and readiness. Overall, the site balances user privacy and security well but could benefit from additional security best practices.

Recommendations

  1. Implement and publish a security.txt file to facilitate vulnerability reporting.
  2. Add and enforce security headers such as CSP, HSTS, and X-Frame-Options to strengthen defense-in-depth.
  3. Provide clear incident response contact channels on the website for security issues.
  4. Enhance transparency around data retention policies and user privacy controls.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy risks.

Technical notes

Notes

The website uses a modern tech stack with JavaScript, SVG icons, lazy loading images, and video autoplay features. It is hosted on Akamai CDN, ensuring fast content delivery and scalability. Google Analytics is used for traffic analysis, and Curator.io powers social media content integration. The site is mobile-optimized with responsive design and accessibility features. SEO is supported by comprehensive meta tags and Open Graph data. No CMS is explicitly detected, suggesting a custom or proprietary platform. Performance is fast with efficient resource loading. Opportunities exist to improve security headers and formalize vulnerability disclosure processes.
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.
