Risk levelHigh

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

The website www.domainmarkt.de/stadt-lueneburg.de operates as a domain marketplace specializing in the sale of premium domains, exemplified by the offering of stadt-lueneburg.de at a promotional price. The business is positioned as a niche reseller targeting German businesses and entrepreneurs seeking to establish a solid online presence through premium domain acquisition. The site is owned by nomino GmbH, a small-sized company operating in the real estate domain sector. Technically, the website employs legacy JavaScript libraries such as jQuery 1.11.0 and easySlider 1.7, with a basic CSS styling approach. The site demonstrates moderate performance and basic mobile optimization but lacks advanced accessibility and SEO features. Security posture is moderate; no HTTPS status is confirmed, and no security headers are detected, which presents an area for improvement. Privacy compliance is minimal, with a basic privacy policy present but no cookie consent mechanism or GDPR compliance indicators. Overall, the site is functional and professional but would benefit from enhanced security and privacy practices to improve 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

7 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

  2. 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.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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 X-Frame-Options header

      Prevents clickjacking attacks

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

    • 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

The business model centers on domain sales and transfer services, supported by customer testimonials and a partnership with DENIC, the German domain registry. The company leverages promotional pricing to attract buyers and provides direct phone support. The market positioning is niche, focusing on premium domains for German businesses, with a clear revenue stream from domain sales. The partnership ecosystem includes DENIC and the parent company nomino GmbH. Growth indicators are limited from the data, but the presence of multiple customer testimonials suggests a stable customer base. The business operates primarily in Germany and targets small to medium enterprises or entrepreneurs.

Security posture

The current security maturity level is basic. The absence of HTTPS confirmation and security headers reduces the security score. No vulnerabilities or exposed sensitive data were detected in the HTML content. However, the use of an outdated jQuery version could pose risks if exploited. There is no evidence of published incident response or security policies, and no contact channels for security incidents are provided. GDPR compliance is minimal, with no cookie consent mechanism or detailed privacy practices. The security culture appears limited, focusing mainly on domain sales without explicit security emphasis.

Recommendations

  1. Implement HTTPS across the entire website to ensure secure communications.
  2. Add standard security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Introduce a cookie consent banner to comply with GDPR and enhance privacy transparency.
  4. Update JavaScript libraries to current versions to mitigate potential vulnerabilities.
  5. Publish clear security and incident response policies and provide dedicated contact channels for security issues.

Technical notes

Notes

The website uses a simple technology stack with jQuery 1.11.0 and easySlider 1.7 for UI interactions. CSS is custom and minimal. There is no detected CMS or advanced framework. Performance is moderate, with no explicit indicators of slow loading but also no advanced optimization. Mobile optimization is basic, with no responsive design details evident. Accessibility features are minimal. SEO is basic, with meta description and keywords present but no structured data or Open Graph tags beyond a Facebook page ID. Hosting provider and SSL/TLS details are not provided, limiting full technical assessment. The site would benefit from modernization and improved technical standards to enhance user experience and security.
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.
