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

Dan.com operates as a domain marketplace platform specializing in the buying, selling, leasing, and renting of domain names. The platform emphasizes secure transactions through its Buyer Protection Program, fast domain ownership transfers, and integration with trusted payment processors like Adyen. The website content is professionally presented with clear navigation and a focus on trust and security, targeting domain investors, businesses, and individuals interested in domain trading. The platform is a subsidiary of Undeveloped BV, with a domain history dating back to 2003, indicating a mature presence in the domain marketplace industry. Technically, the website employs modern JavaScript libraries, Google reCAPTCHA v3 for bot protection, and Google Tag Manager for analytics and marketing. The site is mobile-optimized and uses secure payment integrations. However, explicit security headers are not visible in the provided data, and no cookie consent mechanism is present despite a cookie policy page. The technical implementation is solid but could benefit from enhanced security header configurations and improved privacy compliance features. From a security perspective, the platform demonstrates good practices including secure payments, buyer protection with refund guarantees, and form protection via reCAPTCHA. There are no visible vulnerabilities or exposed sensitive data. However, the absence of incident response contact information and security headers suggests room for improvement in transparency and defense-in-depth. Overall, the security posture is good but not exemplary. The overall risk assessment is moderate with a strong business credibility and technical foundation. Strategic recommendations include implementing security headers, adding explicit incident response contacts, and introducing a cookie consent mechanism to enhance GDPR compliance and user trust. These improvements will strengthen the platform's security posture and regulatory adherence, supporting its market position as a trusted domain marketplace.

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

  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. 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

  4. 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 X-Frame-Options header

      Prevents clickjacking attacks

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

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

Dan.com holds a competitive position as a domain marketplace with a clear value proposition centered on secure and hassle-free domain transactions. Its business model leverages domain sales, leasing, and renting, supported by an API partnership program and brokerage services. The company targets domain investors, businesses, and individuals seeking domain assets. Revenue streams likely include transaction fees, leasing fees, and brokerage commissions. The platform's integration with Adyen and use of Google services indicate a mature partnership ecosystem. Growth indicators include a long domain history and consistent branding under Undeveloped BV. Strategic observations highlight the importance of trust signals such as buyer protection and secure payments in maintaining market leadership.

Security posture

The security maturity level of Dan.com is good, with key strengths including the use of Google reCAPTCHA v3 to mitigate automated abuse, secure payment processing via Adyen, and a buyer protection program that offers refunds within 24 hours if sellers fail to deliver. The platform does not expose sensitive data in its HTML content and uses HTTPS, ensuring encrypted communications. Compliance gaps include the lack of visible security headers (e.g., CSP, HSTS) and absence of explicit incident response or security contact information, which are important for transparency and rapid response. Data protection practices are implied but not explicitly detailed on the page. Incident response readiness is unclear due to missing contact channels. Overall, the security culture appears focused on user protection but could benefit from enhanced transparency and technical controls.

Recommendations

  1. Implement comprehensive security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options to strengthen defense-in-depth.
  2. Add explicit incident response contact information (e.g., security@dan.com or abuse@dan.com) to improve transparency and facilitate vulnerability reporting.
  3. Introduce a cookie consent mechanism to comply fully with GDPR and enhance user privacy controls.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Develop and publish a vulnerability disclosure policy or security.txt file to encourage responsible security reporting.

Technical notes

Notes

The website is built on a custom or proprietary platform with modern JavaScript usage and integration of third-party services such as Google reCAPTCHA and Google Tag Manager. The presence of SVG4Everybody indicates attention to cross-browser SVG support. The site is mobile-optimized and uses responsive design patterns. Performance is moderate, with deferred loading of scripts and use of CDN-hosted libraries. There is no evidence of a common CMS, suggesting a bespoke solution tailored for domain marketplace functionality. Technical risks include the absence of visible security headers and potential gaps in privacy compliance mechanisms. Opportunities exist to modernize security configurations and enhance accessibility and privacy features to align with best practices.
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.
