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

The website dohled.cz currently serves as a domain-for-sale landing page, indicating that the domain is available for purchase. The site provides a single contact email for offers and lists many other domains available for sale with brief descriptions. The business model is focused on domain brokerage and sales, targeting potential buyers or investors interested in acquiring domain names. The website is simple, with basic content and minimal interactivity. From a technical perspective, the site uses standard HTML5 and CSS3 with a responsive design approach suitable for mobile devices. The hosting provider is REG-WEDOS, a known registrar and hosting service. However, there is no evidence of advanced frameworks, CMS, or analytics tools. Performance is moderate, and SEO and accessibility features are basic. Security posture is minimal; no HTTPS/SSL information is provided, and no security headers or policies are present. There are no privacy or cookie policies, and no incident response or vulnerability disclosure mechanisms. The WHOIS data is consistent with the domain's purpose and recent registration date. Overall, the site lacks many standard security and compliance features expected for professional business websites. The overall risk is low in terms of malicious content but moderate due to lack of security best practices and compliance documentation. Strategic recommendations include implementing HTTPS, adding privacy and cookie policies, improving security headers, and providing clearer business and security contact information.

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

9 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

  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 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

      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

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 domain dohled.cz is positioned as a domain-for-sale asset managed by a domain reseller or broker. The business model revolves around selling or brokering domain names, targeting businesses or individuals seeking domain acquisitions. The website lists a broad portfolio of domains with suggested use cases, indicating a diverse inventory. The market position is that of a small-scale domain reseller without direct product or service offerings beyond domain sales. Revenue streams likely come from domain sales and brokerage fees. The target customers are domain investors, startups, and businesses looking for relevant domain names. There is no indication of partnerships or subsidiaries. Growth indicators are limited due to the placeholder nature of the site.

Security posture

The security maturity level of the website is low. The absence of HTTPS/SSL information, security headers, privacy policies, and incident response contacts indicates minimal security controls. No forms or user input fields reduce attack surface but also limit business functionality. There are no visible vulnerabilities or exposed sensitive data, but the lack of security best practices and compliance documentation is a concern. The site does not demonstrate readiness for GDPR or other data protection regulations. Incident response and vulnerability disclosure mechanisms are absent, which could delay response to security issues. Overall, the security culture appears minimal and reactive rather than proactive.

Recommendations

  1. Implement HTTPS with a valid SSL certificate to secure data transmission and improve trust.
  2. Add a comprehensive privacy policy and cookie consent mechanism to comply with GDPR and enhance transparency.
  3. Configure security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  4. Provide clear contact information for security incidents, including abuse and security email addresses.
  5. Enhance website content and navigation to improve user experience and business credibility.

Technical notes

Notes

The website is built with basic HTML5 and CSS3 without any detected JavaScript frameworks or CMS platforms. The design uses flexbox for layout and is mobile responsive. Hosting is provided by REG-WEDOS, a known Czech hosting provider. There are no analytics or tracking scripts, which limits data-driven insights but improves privacy. Performance is moderate given the minimal content and simple structure. The site lacks advanced SEO metadata and accessibility features. There is an opportunity to modernize the technical stack by adding structured data, improving SEO, and implementing security 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.
