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

MOL Bubi is a well-established public bike-sharing service operating in Budapest, Hungary, managed by nextbike GmbH in partnership with BKK and the city of Budapest. The service offers environmentally friendly urban mobility solutions with flexible rental options via a dedicated mobile app. The website reflects a professional and consistent brand image, targeting urban commuters and tourists seeking convenient transport alternatives. Technically, the site leverages modern web technologies including Bootstrap, jQuery, and integrates third-party analytics and marketing tools such as Google Analytics and Facebook Pixel, hosted on AWS and Cloudflare CDN, ensuring good performance and availability. Security posture is strong with HTTPS, security headers, and cookie consent mechanisms in place, though the absence of a public security policy and incident response contacts suggests room for improvement. Overall, the site is trustworthy, compliant with GDPR, and provides clear contact information and social media presence, supporting user confidence.

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

5 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 Cookie Policy found

      GDPR requires clear information about cookie usage

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

  2. 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 X-Frame-Options header

      Prevents clickjacking attacks

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

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…
  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

The business operates in the transportation sector, specifically urban bike-sharing, with a medium-sized footprint and a history dating back to 2014. Its business model combines subscription passes and pay-as-you-go rates, appealing to a broad audience including residents and visitors. Partnerships with local government entities like BKK and Budapest city enhance its market position and credibility. The company benefits from a strong digital presence and integration with nextbike's global platform, enabling scalability and operational efficiency. Marketing efforts include social media engagement and targeted advertising via Taboola and Facebook. The company’s growth is indicated by network expansions and service updates communicated through news sections. No direct revenue data is available, but the model suggests recurring income from subscriptions and usage fees.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, comprehensive cookie consent aligned with GDPR, and use of security headers to mitigate common web threats. The integration of third-party analytics is managed with anonymization features to protect user privacy. However, the lack of a dedicated security policy page and incident response contact details limits transparency and preparedness perception. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of iframe for login is a secure practice isolating authentication. Recommendations include publishing security policies, establishing a vulnerability disclosure program, and enhancing accessibility compliance to further strengthen security culture and user trust.

Recommendations

  1. Publish a dedicated security policy and incident response contact page to improve transparency and user trust.
  2. Implement a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  3. Enhance website accessibility features to comply with WCAG standards and improve user experience for all users.
  4. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Maintain and communicate clear data retention and privacy practices to reinforce GDPR compliance.

Technical notes

Notes

The website is built on a modern technology stack including Bootstrap for responsive design, jQuery for DOM manipulation, and Font Awesome for icons. It uses Google Tag Manager to manage analytics and marketing tags efficiently. Hosting is provided via AWS and Cloudflare CDN, ensuring fast content delivery and resilience. The site is mobile-optimized with good performance metrics and SEO practices. The use of iframe integration for login and account management isolates sensitive operations, enhancing security. Some technical debt may exist due to reliance on older jQuery versions, and accessibility could be improved. Overall, the technical infrastructure supports a reliable and user-friendly service.
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.
