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

Rekola Bikesharing s.r.o. operates a bike sharing service primarily in Czech cities such as Prague and Brno, as well as select international locations. The company offers app-based rentals of distinctive pink bikes, targeting urban commuters and casual city travelers. Their business model includes pay-per-ride, subscription plans, and corporate benefits, positioning them as a well-established player in the urban transportation sector since 2013. The website reflects a professional and consistent brand image with clear business information and active social media presence. Technically, the website uses modern frontend technologies including Bootstrap 4 and deferred JavaScript loading, with mobile optimization and SEO best practices in place. The presence of app store links and a progressive web app manifest indicates a mature digital infrastructure supporting multiple platforms. Performance is moderate with good mobile responsiveness and basic accessibility features. From a security perspective, the site enforces HTTPS and avoids exposing sensitive data in the HTML. However, it lacks explicit security headers such as Content-Security-Policy and cookie consent mechanisms, which are recommended for enhanced security and GDPR compliance. The absence of WHOIS data limits domain trust analysis, but the visible company registration details and contact information support legitimacy. Overall, Rekola's website is professional, secure, and user-friendly, with minor improvements recommended in privacy compliance and security headers. The risk profile is low, and the company demonstrates a solid market position in urban transportation.

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

9 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

    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

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

Rekola Bikesharing holds a strong position in the Czech urban mobility market, leveraging a recognizable brand and a distinctive pink bike fleet. Their revenue streams include individual rides, subscriptions, and corporate partnerships, indicating diversified income sources. The company targets urban commuters and environmentally conscious users seeking convenient short-distance transport. Partnerships with well-known brands and event collaborations enhance their market visibility. Growth indicators include expansion into multiple cities and international presence in Bratislava and Tallinn. The business model is asset-light with app-driven operations, enabling scalability. Strategic observations suggest focusing on enhancing privacy compliance and expanding digital marketing to strengthen competitive advantage.

Security posture

The website demonstrates a moderate to good security posture with HTTPS enforced and no visible exposure of sensitive data. The use of deferred JavaScript loading reduces initial load risks. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security represents a gap that could be exploited in certain attack scenarios. No vulnerability disclosures or incident response contacts are published, limiting transparency. GDPR compliance is partially addressed via a privacy policy but lacks cookie consent mechanisms. The security culture appears basic but functional, with room for improvement in formalizing policies and enhancing technical controls.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to mitigate common web vulnerabilities.
  2. Deploy a cookie consent banner or mechanism to ensure full GDPR compliance and enhance user privacy transparency.
  3. Publish a dedicated security policy and incident response contact information to improve trust and readiness.
  4. Regularly audit third-party scripts and dependencies to identify and remediate potential vulnerabilities.
  5. Enhance accessibility features and conduct periodic penetration testing to maintain a robust security posture.

Technical notes

Notes

The website is built on a modern frontend stack using Bootstrap 4 and JavaScript with deferred loading for performance optimization. It includes a progressive web app manifest indicating support for mobile app-like experiences. External resources are loaded from trusted CDNs and Google Fonts. The site is mobile optimized with responsive design and good SEO metadata including Open Graph tags. However, no CMS or backend technology is explicitly detected. Hosting provider details are not available from the provided data. Performance is moderate with potential for improvement in accessibility and security header implementation. The technical debt appears low, but modernization opportunities exist in privacy and security 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.
