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

Omnix.cz is a Czech-based technology company operated by SHEAN s.r.o., providing an integrated CMS and e-commerce platform tailored for businesses seeking unified web content management and online sales solutions. The platform emphasizes system integrations, multilingual content, configurators, and automation to serve a diverse client base with over 170 e-shop solutions and 200 web presentations. Technically, the website employs modern web technologies including HTTPS, Google Tag Manager, and reCAPTCHA, ensuring a secure and user-friendly experience. However, the absence of WHOIS data and explicit security policies slightly diminishes trustworthiness. Overall, the site is professional, well-structured, and compliant with GDPR, though improvements in security transparency and WHOIS data availability are recommended.

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

6 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

      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. 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

Omnix positions itself as a specialized B2B provider in the CMS and e-commerce sector within the Czech Republic, leveraging partnerships and client references to establish credibility. The business model focuses on customizable solutions integrating accounting and payment systems, targeting medium to small enterprises requiring scalable online stores and content management. The parent company SHEAN s.r.o. supports the platform with marketing and development expertise. Growth indicators include a significant annual turnover and numerous active projects. The ecosystem includes multiple partner domains, enhancing service reach and client trust.

Security posture

The website demonstrates a moderate to good security posture with HTTPS enforced, use of Google reCAPTCHA to protect forms, and a cookie consent mechanism aligned with GDPR. However, the lack of published security policies, incident response contacts, and vulnerability disclosure reduces transparency and preparedness. No critical vulnerabilities or exposed sensitive data were detected in the content. Security headers appear to be missing or not detected, which is a recommended enhancement. Overall, the security maturity is adequate for the business size but could benefit from formalized policies and improved header configurations.

Recommendations

  1. Implement and publish a comprehensive security policy including incident response procedures.
  2. Add HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-XSS-Protection.
  3. Publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Ensure WHOIS data is complete and publicly available to improve domain trustworthiness.
  5. Enhance accessibility features to meet higher standards and improve user experience.

Technical notes

Notes

The website uses a custom CMS platform (Omnix) supported by modern frontend technologies including jQuery, SVG icons, and Google services for analytics and bot protection. The site is mobile optimized with responsive design and good SEO practices such as meta tags and structured navigation. Performance is moderate with asynchronous script loading and optimized images. However, the absence of detected security headers and incomplete WHOIS data represent technical risks. Hosting provider details are not disclosed, limiting infrastructure assessment. Overall, the technical implementation is solid but could be improved with enhanced security configurations and transparency.
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.
