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

Mojekolo.cz is a Czech Republic-based medium-sized retail business specializing in bicycles, electric bicycles, and cycling accessories. It operates both online and through 14 physical stores, positioning itself as the largest cycling store in the region. The website is professionally designed with good content quality and clear navigation, targeting cycling enthusiasts and outdoor sports consumers primarily in the Czech Republic and Slovakia. Technically, the site uses modern JavaScript libraries, Google Tag Manager for analytics, and implements cookie consent mechanisms, indicating a moderate level of digital maturity. Security posture is adequate with HTTPS enforced and no exposed sensitive data, but lacks advanced security headers and published security policies. The absence of WHOIS data limits trust assessment, but the visible business presence and contact information support legitimacy. Overall, the site is functional, trustworthy, and compliant with basic privacy requirements, though improvements in transparency and security practices 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

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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  2. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  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 Content-Security-Policy header

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 · found on this site
  • 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

Mojekolo.cz holds a strong market position as the largest cycling retailer in its region, leveraging a hybrid business model combining e-commerce with physical retail stores. Its key services include sales of bicycles, electric bikes, and related accessories, supported by a network of 14 stores. The company targets active lifestyle consumers and outdoor sports enthusiasts, with a focus on quality products and customer service. The website's integration of marketing tools like Google Tag Manager suggests active digital marketing efforts. However, the lack of publicly available WHOIS and detailed company registration data reduces transparency. The business appears stable with a consistent brand presence and customer trust signals such as product reviews and free shipping offers.

Security posture

The website demonstrates a baseline security posture with HTTPS enabled and cookie consent implemented, which aligns with GDPR requirements. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options indicates room for improvement in mitigating common web vulnerabilities. No security policy or incident response contacts are published, which could hinder effective vulnerability reporting and incident management. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of third-party scripts like Google Tag Manager is standard but requires ongoing monitoring to prevent supply chain risks. Overall, the security maturity is moderate but would benefit from enhanced security controls and transparency.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service to improve transparency and compliance.
  2. Implement and configure security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Establish and publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Enhance WHOIS transparency by ensuring domain registration data is publicly available and accurate.
  5. Regularly audit third-party scripts and tracking tools to minimize supply chain security risks.

Technical notes

Notes

The website employs a modern front-end technology stack including JavaScript, Bootstrap framework, Flexslider for image carousels, and FontAwesome for icons. Google Tag Manager is used for analytics and marketing tracking. The site is mobile responsive with good navigation and SEO meta tags. Cookie consent is managed via a vanilla JavaScript library. Performance appears moderate with asynchronous loading of scripts. No CMS or hosting provider information is explicitly detected. Accessibility features are basic but present. The technical infrastructure supports a professional e-commerce experience but could be enhanced with improved security headers and performance optimizations.
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.
