83/100

Risk levelLow

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

The website www.deinhandy.de operates as an e-commerce platform specializing in the sale of mobile phones and mobile tariff plans in Germany. It targets consumers seeking affordable handsets with or without contracts, offering a variety of manufacturers and network options. The business model focuses on online retail and tariff comparison, positioning itself as a competitive player in the German telecommunications market. The site uses modern web technologies including React and Next.js, hosted on Amazon AWS infrastructure, and integrates marketing and analytics tools such as Google Tag Manager and AB Tasty. While the website demonstrates good design quality, mobile optimization, and user experience, it lacks visible privacy, cookie, and terms of service policies, which impacts its privacy compliance score. Security posture is moderate with no detected WAF or blocking mechanisms, but absence of security headers and incident response information suggests room for improvement. Overall, the site is professional and functional but would benefit from enhanced transparency and security practices to increase trust and compliance.

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

The platform serves the telecommunications sector with a focus on retailing mobile devices and contracts. Its competitive advantage lies in aggregating tariff plans and handset deals, appealing to price-conscious consumers in Germany. The business likely generates revenue through handset sales, contract commissions, and possibly affiliate partnerships. The target audience includes general consumers in Germany interested in mobile connectivity solutions. The use of AWS hosting and modern frameworks indicates a commitment to scalable and performant infrastructure. However, the lack of explicit business registration details and contact information limits full business credibility assessment. The absence of visible certifications or trust badges suggests potential areas for building consumer confidence. The company appears to operate independently without clear parent or subsidiary relationships disclosed in the content.

Security posture

The website employs HTTPS and modern JavaScript frameworks but lacks explicit security headers such as Content-Security-Policy or X-Frame-Options in the analyzed content. No security or incident response policies are visible, and no dedicated security contact channels are provided. The integration of third-party marketing and analytics scripts introduces moderate tracking but no evident vulnerabilities or exposed sensitive data were detected. The absence of privacy and cookie policies is a compliance gap under GDPR. Overall, the security maturity is moderate but could be significantly improved by implementing security best practices, publishing clear policies, and establishing incident response mechanisms.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies to comply with GDPR and enhance user trust.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to improve security posture.
  3. Provide clear contact information including security incident response and data protection officer contacts.
  4. Conduct regular security audits to identify and remediate potential vulnerabilities in third-party scripts and site infrastructure.
  5. Enhance accessibility and SEO features to improve compliance and user experience.

Technical notes

Notes

The website is built using Next.js, a React-based framework, indicating a modern and scalable front-end architecture. Hosting on AWS suggests reliable infrastructure. The site uses Google Tag Manager and AB Tasty for analytics and marketing optimization. Performance is moderate with preloading of key images and fonts, and mobile optimization is good. However, accessibility features appear basic and could be improved. SEO is supported by meta tags and Open Graph data but lacks structured data like JSON-LD for enhanced search presence. No CMS is explicitly detected, implying a custom or headless approach. The technical stack is contemporary but would benefit from enhanced security configurations and compliance documentation.
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.
