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

Gemioptal.cz is an e-commerce website offering specialized eye health supplements developed by the Czech company GEMINI oční klinika a.s. The company leverages its expertise in ophthalmology to market products such as Gemioptal HERBAL, FORTE, and TOP Q, targeting consumers seeking to maintain or improve eye health. The website is professionally designed with clear navigation, customer testimonials, and a bonus program to enhance customer engagement. Technically, the site uses established technologies including jQuery, Google Tag Manager, and cookie consent scripts, ensuring compliance with GDPR and providing a good user experience across devices. Security posture is adequate with HTTPS enforced and cookie consent mechanisms in place; however, the absence of security headers and use of an outdated jQuery version present moderate risks. The lack of WHOIS data transparency slightly reduces domain trustworthiness, though the business information and contact details are clearly presented and verifiable. Overall, the site is a credible and professional platform for health supplement sales in the Czech market.

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.

Priority findings

7 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

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 operates in the healthcare sector, focusing on nutritional supplements for eye health. Its market positioning is niche but strong within the Czech Republic, supported by its affiliation with a reputable eye clinic. The business model is direct-to-consumer e-commerce, with additional customer retention strategies such as a bonus program. Revenue streams likely derive from product sales and bundled packages. The target audience includes adults concerned with vision health and age-related eye conditions. The partnership with GEMINI oční klinika a.s. enhances credibility and provides a competitive advantage. The website content and marketing tools indicate a mature digital presence with PPC campaigns and tracking for performance optimization.

Security posture

The website demonstrates a moderate security maturity level. HTTPS is properly implemented, and cookie consent mechanisms comply with GDPR requirements. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces protection against common web attacks. The use of an outdated jQuery version may expose the site to known vulnerabilities. No public incident response or security policies are found, and no security.txt file is present for vulnerability disclosure. The site does not expose sensitive data or show signs of active vulnerabilities. Overall, while basic security practices are followed, improvements are needed to enhance resilience and compliance.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  2. Upgrade jQuery and other JavaScript libraries to the latest secure versions to reduce exposure to known exploits.
  3. Publish a security.txt file and incident response policy to improve transparency and readiness for vulnerability reporting.
  4. Conduct regular security audits and penetration testing to identify and remediate potential weaknesses.
  5. Enhance accessibility features and performance optimizations to improve user experience and SEO.

Technical notes

Notes

The website uses a traditional tech stack with jQuery 1.12.4, Google Tag Manager, and Owl Carousel for UI components. Cookie consent is managed via a third-party script ensuring GDPR compliance. The site is mobile responsive with good navigation and SEO meta tags. Performance is moderate, with potential improvements in script optimization and caching. No CMS is explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not disclosed. The site lacks modern frontend frameworks and some accessibility features, indicating room for modernization. Overall, the technical implementation supports the business needs but could benefit from updates to improve security, performance, and maintainability.
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.
