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

RegZone.cz is a professional domain registration and hosting service provider operating primarily in the Czech Republic. The company offers a broad portfolio of over 700 top-level domains including popular extensions such as .cz, .com, and .eu, complemented by free SSL certificates, email hosting, DNS management with DNSSEC, and domain parking services. The business is part of the larger ZONER a.s. group, which is a recognized player in the Czech internet services market. Their website is well-designed, mobile-optimized, and provides clear navigation and comprehensive customer support information. From a technical perspective, RegZone.cz employs modern web technologies including Bootstrap 5, jQuery, and Lightbox2, alongside Google Tag Manager and Google Analytics for tracking and analytics. The site enforces HTTPS and offers a granular cookie consent mechanism, demonstrating good privacy compliance. However, there is room for improvement in security headers and explicit security policy disclosures. Security posture is solid with free SSL certificates, DNSSEC support, and 24/7 technical support, but the absence of visible security headers and vulnerability disclosure mechanisms suggests opportunities for enhancement. The WHOIS data is unavailable from the provided source, which slightly impacts transparency but does not detract significantly from the overall trustworthiness given the company's accreditation and professional presentation. Overall, RegZone.cz presents a trustworthy, professional, and technically competent service offering in the domain registration and hosting sector, with strong compliance and customer focus. Strategic improvements in security policy transparency and WHOIS data availability would further strengthen their market position and customer trust.

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 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

    • 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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

  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

      SSL Certificate Expires Soon

      SSL certificate expires in 21 days

      What to do: Renew SSL certificate before expiration

      • NIS2 21(2)(h)
      • IR 2024/2690 9.2(c): Implementing Regulation (EU) 2024/2690, Annex point 9.2(c): Cryptography

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

RegZone.cz holds a strong market position as an accredited domain registrar with a comprehensive offering of domain extensions and integrated hosting services. Their business model focuses on providing end-to-end domain and hosting solutions to individuals and businesses, leveraging the backing of ZONER a.s. The company benefits from a broad partner ecosystem including Czechia.com and SSLmarket.cz, enhancing their service portfolio. Customer testimonials and accreditation badges reinforce their credibility. The target customer segments include Czech and regional clients seeking reliable domain registration and hosting. Growth indicators include continuous service expansion, AI domain suggestion tools, and active content updates. The company’s revenue streams likely derive from domain registrations, renewals, hosting packages, and value-added services such as SSL certificates and email hosting.

Security posture

RegZone.cz demonstrates a mature security posture with enforced HTTPS, free SSL certificates for all domains, DNSSEC support, and 24/7 technical support. The presence of a cookie consent modal with granular user controls indicates strong privacy compliance. However, the absence of explicit security headers (e.g., CSP, HSTS) and a published security policy or vulnerability disclosure program suggests areas for improvement. Incident response contact information is available, but could be more prominently featured. No vulnerabilities or exposed sensitive data were detected in the analysis. Overall, the security culture appears proactive but would benefit from formalized policies and enhanced technical controls.

Recommendations

  1. Implement and enforce security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options to enhance protection against common web attacks.
  2. Publish a comprehensive security policy and consider adding a security.txt file or vulnerability disclosure program to encourage responsible reporting of security issues.
  3. Enhance visibility and accessibility of incident response contacts and procedures to improve customer trust and readiness.
  4. Regularly audit and update third-party scripts and libraries to mitigate risks from vulnerable dependencies.
  5. Maintain transparency in domain registration data by ensuring WHOIS information is accessible and accurate, improving trust and compliance.

Technical notes

Notes

The website is built on a modern technology stack including Bootstrap 5 for responsive design, jQuery for DOM manipulation, and Lightbox2 for image display. Google Tag Manager and Google Analytics are used for analytics and tracking. The site is mobile-optimized with good accessibility and SEO practices. Performance is moderate, with potential for optimization in loading speed. No CMS was explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not disclosed. The technical implementation supports a professional user experience but could benefit from enhanced security headers and performance tuning.
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.
