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 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 Strict-Transport-Security header

      Forces HTTPS connections

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

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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

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

Smart4City holds a competitive position in the Czech smart parking market, offering a streamlined mobile payment solution that eliminates traditional parking tickets. Its business model relies on app-based transactions, targeting urban drivers in multiple municipalities. The company benefits from partnerships with city administrations, as evidenced by the list of supported cities on the website. Revenue streams likely include transaction fees or service charges associated with parking payments. The platform's integration with major app stores and payment providers enhances user adoption and trust. Growth potential exists through expansion to additional cities and enhancement of service features. The company maintains a focused ecosystem with limited external dependencies, emphasizing direct customer engagement via mobile applications and web presence.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, comprehensive security headers, and secure form handling. No exposed sensitive data or vulnerable libraries were detected in the analysis. However, the absence of a published security policy, incident response plan, or vulnerability disclosure program represents a compliance gap and potential risk in incident management. The lack of a cookie consent mechanism may also expose the company to regulatory scrutiny under GDPR. Overall, the security measures in place are robust for the website's scope, but formalizing policies and transparency around security practices would strengthen the security culture and user trust.

Recommendations

  1. Implement a cookie consent banner to ensure compliance with EU cookie laws and GDPR.
  2. Publish a detailed security policy and incident response plan accessible to users and partners.
  3. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Enhance contact information with dedicated security and abuse contact channels.
  5. Regularly review and update third-party scripts and dependencies to mitigate emerging vulnerabilities.

Technical notes

Notes

The website is built using Next.js and React frameworks, leveraging Tailwind CSS for styling and Google Maps API for geolocation features. Hosting and DNS services are provided by Cloudflare, ensuring performance optimization and security. The site is mobile-optimized with responsive design and accessibility considerations. Performance is fast with asynchronous loading of scripts and preloading of fonts. SEO is supported by appropriate meta tags and structured navigation. No CMS was detected, indicating a custom or framework-based implementation. The technical infrastructure is modern and well-maintained, minimizing technical debt and supporting scalability.
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.
