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

Elektronické tržiště Gemin is a Czech Republic-based electronic marketplace platform designed to facilitate public sector procurement and government contracts. Operated by QCM, s.r.o., it serves as a B2B platform enabling public administration and self-government entities to electronically issue public tenders with minimal costs. The platform positions itself as the first next-generation electronic marketplace in the Czech Republic, emphasizing simplicity, efficiency, and transparency in public sector commerce with commercial entities. The website targets government bodies and suppliers interested in public procurement processes. Technically, the website employs a custom CMS named Gemin, utilizing legacy JavaScript libraries such as jQuery 1.8.3, jQuery UI 1.10.2, Prototype.js, and Scriptaculous. It uses Google Fonts and Google Analytics for tracking. The site is served over HTTPS, but the use of outdated libraries introduces potential security risks. The website demonstrates moderate performance and basic mobile optimization and accessibility features. From a security perspective, the site enforces HTTPS and uses cookies with domain and expiry settings. However, it lacks modern security headers like Content-Security-Policy and uses outdated JavaScript libraries that may expose vulnerabilities. No explicit privacy, cookie, or security policies are found, and no incident response or vulnerability disclosure information is provided. WHOIS data is unavailable, likely due to privacy protection, limiting domain registration trust verification. Overall, the security posture is moderate but could be improved by updating libraries and adding security policies. The overall risk assessment indicates a legitimate and professionally presented public sector platform with moderate technical maturity and some security gaps. Strategic recommendations include updating JavaScript libraries, implementing security headers, publishing privacy and cookie policies, enhancing accessibility and mobile responsiveness, and conducting regular security audits 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.

Priority findings

11 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

  2. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • Critical

      DNS Resolution Failed

      Unable to resolve domain A records

      What to do: Verify domain is properly configured and not expired

  3. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319

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

Gemin.cz operates as a specialized electronic marketplace for public procurement in the Czech Republic, targeting government ministries, local authorities, and suppliers. Its competitive advantage lies in being the first next-generation platform in the country, offering a transparent and cost-effective solution for public tenders. The business model is B2B SaaS-like, providing free registration for both contracting authorities and suppliers, facilitating electronic tendering processes compliant with Czech legislation. Revenue streams likely include service fees or value-added services related to tender management. The platform shows strong integration with public sector entities, evidenced by links to multiple ministries and public organizations. Growth indicators include active tender counts and ongoing updates. The partnership ecosystem includes QCM, s.r.o. as the solution provider, with social media presence on Facebook and Twitter enhancing outreach. Strategic observations suggest a focus on expanding public sector adoption and improving technical infrastructure to maintain market leadership.

Security posture

The security maturity of Gemin.cz is moderate. The site enforces HTTPS, which is mandatory for secure communications. However, the use of outdated JavaScript libraries such as jQuery 1.8.3 and jQuery UI 1.10.2 introduces potential vulnerabilities that could be exploited. The absence of modern security headers like Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options reduces protection against common web attacks. No explicit privacy or cookie policies are published, which is a compliance gap under GDPR. Incident response readiness and vulnerability disclosure mechanisms are not evident, limiting transparency and responsiveness to security incidents. No exposed sensitive data or credentials were detected in the HTML content. Overall, the platform should prioritize updating its technology stack, implementing security headers, and publishing comprehensive privacy and security policies to enhance its security posture and regulatory compliance.

Recommendations

  1. Update all JavaScript libraries and dependencies to their latest secure versions to mitigate known vulnerabilities.
  2. Implement comprehensive security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to strengthen web security.
  3. Publish clear and comprehensive privacy and cookie policies to improve GDPR compliance and user trust.
  4. Enhance accessibility and mobile responsiveness to improve user experience across devices and for users with disabilities.
  5. Establish and publicize incident response and vulnerability disclosure procedures to demonstrate security maturity and transparency.

Technical notes

Notes

The website is built on a custom CMS platform named Gemin, utilizing legacy JavaScript frameworks such as Prototype.js and Scriptaculous alongside older versions of jQuery and jQuery UI. Google Fonts and Google Analytics are integrated for typography and analytics respectively. The site uses asynchronous loading for analytics scripts and includes multiple custom JavaScript modules for UI enhancements and form validation. Performance is moderate with basic mobile optimization and accessibility features. The HTML structure is valid and includes meta tags for SEO and language specification. However, the use of outdated libraries presents technical debt and security risks. There is an opportunity to modernize the tech stack, improve performance, and enhance security configurations to reduce technical risks and improve operational stability.
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.
