Gemerka is a Slovakian company specializing in mineral water products with a focus on the optimal balance of magnesium and calcium for health benefits. The website positions Gemerka as a niche regional brand targeting health-conscious consumers interested in natural mineral supplementation. The business model revolves around retailing mineral water and educating consumers on its benefits, supported by expert testimonials and social media engagement. Technically, the website is built on WordPress using Elementor and Slider Revolution, with modern SEO tools like Rank Math and Google Tag Manager integrated, indicating a moderate level of digital maturity. The site is mobile-optimized and presents a professional design with clear navigation and consistent branding. Security-wise, the site enforces HTTPS and includes cookie consent mechanisms, but lacks advanced security headers and explicit incident response or vulnerability disclosure information. Overall, the website is trustworthy and compliant with GDPR, though it could improve in security policy transparency and contact information visibility. Strategic recommendations include enhancing security headers, publishing detailed security and incident response policies, and improving contact accessibility to strengthen trust and compliance.

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.

  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

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

Gemerka operates in the retail sector, focusing on mineral water products enriched with magnesium and calcium in an optimal ratio. The company leverages expert endorsements to build credibility and targets a general audience interested in health and wellness. Its digital presence includes active social media channels on Facebook, Instagram, and YouTube, supporting brand engagement and marketing. The website's business model is straightforward retail with educational content, positioning Gemerka as a specialized health-oriented brand in Slovakia. There is no evidence of parent or subsidiary companies, suggesting a small to medium-sized independent operation. The use of modern CMS and SEO tools indicates an investment in digital marketing and customer outreach. However, the absence of visible contact emails or phone numbers on the homepage may limit direct customer interaction. The company could benefit from expanding transparency around business credentials and certifications to enhance market position.

Security posture

The website demonstrates a baseline security posture with HTTPS enabled and a cookie consent banner compliant with GDPR. However, it lacks several recommended security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options, which are important for mitigating common web vulnerabilities. No exposed sensitive data or vulnerable libraries were detected in the provided content. The absence of explicit security policies, incident response contacts, or vulnerability disclosure mechanisms indicates limited transparency in security governance. The site uses popular WordPress plugins, which require regular updates to prevent exploitation. Overall, the security posture is adequate for a small retail website but could be significantly improved by implementing additional security headers, publishing security policies, and establishing formal incident response channels.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common attacks.
  2. Publish a dedicated security policy and incident response page with clear contact channels such as security@ or abuse@ emails.
  3. Regularly update WordPress core and all plugins to mitigate risks from known vulnerabilities.
  4. Improve visibility and accessibility of contact information on the website to enhance customer trust and support.
  5. Consider establishing a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.

Technical notes

Notes

The website is built on WordPress CMS with Elementor page builder and Slider Revolution for dynamic content presentation. It uses jQuery and Google Tag Manager for analytics and tracking. SEO is managed via Rank Math plugin, indicating attention to search engine optimization. The site is mobile responsive and loads with moderate performance. Accessibility features are basic but present. The technical stack is modern and widely supported, though reliance on multiple plugins requires diligent maintenance to avoid technical debt and security risks. Hosting provider details were not identified. Overall, the technical infrastructure supports a professional and user-friendly experience but could benefit from performance optimization and enhanced accessibility compliance.
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.
