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

CityOne is a Czech-based platform operated by Via Aurea, s.r.o., focused on smart city solutions including projects, products, and expert connections. The website serves municipalities, urban planners, and technology providers with resources and a marketplace to foster smart city development. Technically, the site uses a modern stack including jQuery, Bootstrap, Google APIs, and Nette Framework components, delivering a responsive and well-structured user experience. Security posture is solid with HTTPS, reCAPTCHA, and cookie consent, though it lacks some advanced security headers and explicit privacy policy pages. The absence of WHOIS data reduces transparency but does not detract significantly from the site's legitimacy given its professional presentation and active content. Overall, the platform is a credible resource in the smart city domain with room for improvement in privacy and security disclosures.

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

10 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. 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

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

CityOne occupies a niche market in smart city technology and urban development in the Czech Republic and Central Europe. Its business model is a platform marketplace connecting smart city projects, products, and experts with municipalities and stakeholders. The company Via Aurea, s.r.o. operates the site, targeting government entities, urban planners, and technology providers. The platform publishes news, hosts events, and facilitates collaboration, indicating a community-driven growth approach. The lack of explicit business registration details and WHOIS transparency is a minor concern but the site’s professional content and partnerships suggest a stable operation.

Security posture

The website demonstrates a moderate to good security maturity level. HTTPS is enforced, and Google reCAPTCHA is used to protect forms from abuse. A cookie consent mechanism is implemented with GDPR language, indicating awareness of privacy regulations. However, the site lacks visible security headers such as Content-Security-Policy and X-Frame-Options, which could enhance protection against common web attacks. No security.txt or vulnerability disclosure information is present, limiting incident response readiness. No exposed sensitive data or vulnerable libraries were detected. Overall, the security posture is adequate but could be improved with additional headers and transparency.

Recommendations

  1. Implement comprehensive privacy and terms of service pages to improve compliance and user trust.
  2. Add security headers like Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to enhance security.
  3. Publish a security.txt file to facilitate vulnerability disclosure and incident response.
  4. Improve WHOIS transparency or provide clear domain registration information to enhance legitimacy.
  5. Regularly audit and update third-party libraries and scripts to mitigate potential vulnerabilities.

Technical notes

Notes

The website uses a mature technology stack with jQuery, Bootstrap, Google APIs, and Nette Framework AJAX components. It loads asynchronously and includes modern UI elements like slick sliders and lightboxes. The site is mobile responsive with good navigation clarity and SEO meta tags. Performance is moderate, with some legacy libraries like jQuery 1.5.x versions, which could be updated for better speed and security. Accessibility is basic but functional. Hosting provider details are not explicitly found. Overall, the technical infrastructure supports the business goals but could benefit from modernization and performance tuning.
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.
