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

8 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

      Forces HTTPS connections

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

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

Kolofix positions itself as a specialized bicycle repair service provider targeting cyclists throughout the Czech Republic. Its competitive advantage lies in its extensive branch network, mobile service offerings, and transparent online booking system. The business model focuses solely on repair services without selling bicycles, which differentiates it from typical bike shops. Revenue streams likely include service fees for repairs and maintenance, with potential upselling of parts and accessories. The company leverages digital marketing and analytics tools to optimize customer acquisition and retention. Partnerships with payment providers and integration of multiple payment methods enhance customer convenience. Growth indicators include a significant number of completed services and a clear focus on customer satisfaction as evidenced by testimonials. The company maintains active social media presence on Instagram and Facebook, supporting brand engagement and community building.

Security posture

The website demonstrates a good security maturity level with enforced HTTPS and a robust cookie consent mechanism that allows users granular control over cookie categories, supporting GDPR compliance. The use of reputable third-party analytics and marketing tools is balanced with user privacy considerations. However, the absence of published security policies, incident response contacts, and terms of service pages indicates gaps in formal security governance and legal transparency. No vulnerabilities or exposed sensitive data were detected in the HTML content. The site would benefit from implementing security headers such as Content-Security-Policy and X-Frame-Options to enhance protection against common web attacks. Overall, the security posture is adequate for the business type but could be improved to meet higher compliance and trust standards.

Recommendations

  1. Publish a dedicated security policy and incident response contact information to improve transparency and readiness.
  2. Add a terms of service page to clarify user rights and obligations.
  3. Implement HTTP security headers (CSP, X-Frame-Options, X-Content-Type-Options) to strengthen web security.
  4. Regularly review and update third-party scripts to mitigate potential vulnerabilities.
  5. Enhance website accessibility features to comply with standards and improve user experience for all visitors.

Technical notes

Notes

The website is built using a combination of modern front-end technologies including jQuery, Swiper.js for sliders, and Google Fonts for typography. It integrates multiple third-party services such as Google Analytics, Microsoft Clarity, Facebook Pixel, Google Tag Manager, and Tawk.to live chat, indicating a mature digital marketing and customer engagement strategy. Hosting is provided by Active24, a known Czech hosting provider, ensuring regional performance optimization. The site is mobile responsive with good navigation clarity and SEO optimization through proper meta tags and Open Graph data. Performance is moderate, likely influenced by multiple external scripts. No CMS was explicitly detected, suggesting a custom or static site architecture. Overall, the technical implementation supports the business goals effectively but could benefit from performance tuning 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.
