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.

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 company is positioned as a key player in the Czech domain registration and hosting market, leveraging partnerships with related service providers such as Czechia.com and ZonerCloud.cz. Their business model focuses on providing integrated domain and hosting services with value-added features like free SSL and email hosting. The target customers range from individual domain buyers to businesses requiring professional hosting solutions. The presence of multiple accreditations and customer testimonials indicates a stable and trusted operation. The company benefits from a diversified service ecosystem and a strong brand presence in the region. Growth potential exists through expanding TLD offerings and enhancing API services for B2B clients.

Security posture

The website exhibits a good security maturity level with HTTPS enforced site-wide, free SSL certificates for customers, and DNSSEC support for domain security. The cookie consent modal complies with GDPR requirements, offering granular user control over cookie categories. However, the lack of visible HTTP security headers such as Content Security Policy (CSP) and HSTS is a gap that could be addressed to harden security further. No vulnerabilities or exposed sensitive data were detected in the HTML content. Incident response contact information is available, but a formal security policy or vulnerability disclosure program is not published. Overall, the security posture is strong but could benefit from formalized policies and enhanced header configurations.

Recommendations

  1. Implement HTTP security headers including CSP, HSTS, and X-Frame-Options to improve browser security.
  2. Publish a security.txt file to facilitate vulnerability reporting and improve transparency.
  3. Enhance visibility and detail of incident response procedures and contacts on the website.
  4. Regularly audit third-party scripts and dependencies to mitigate potential vulnerabilities.
  5. Develop and publish a formal security policy outlining data protection and compliance measures.

Technical notes

Notes

The website uses a modern and widely supported technology stack including Bootstrap 5 for responsive design, jQuery for DOM manipulation, and Lightbox2 for image display. Google Tag Manager and Google Analytics are integrated for tracking and analytics purposes. The site is mobile optimized with good accessibility features and SEO metadata. Performance is moderate with video background usage and multiple external resources, but overall user experience is smooth. No CMS was explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not disclosed. The technical implementation is solid with opportunities for optimization in 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.
