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

CityCoins operates a niche cryptocurrency platform that enables users to support their favorite cities while earning Bitcoin yield. The platform focuses on city-themed coins such as MiamiCoin and NYC Coin, targeting cryptocurrency enthusiasts and city supporters. The website is professionally designed using modern web technologies including Webflow, Google Fonts, and integrates analytics tools like Cloudflare Web Analytics and Fathom Analytics. Hosting appears to be via Webflow with Cloudflare CDN, providing good performance and mobile optimization. Security posture is moderate with HTTPS enabled and no exposed sensitive data, but lacks visible security headers and formal privacy or terms of service documentation. WHOIS data is fully redacted, which is common in crypto projects but reduces transparency. Overall, the site is functional and professional but could improve in compliance and security transparency.

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. 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';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

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

CityCoins positions itself as a specialized crypto platform focusing on city-based tokens, leveraging community engagement and Bitcoin yield incentives. The business model revolves around mining and investing in citycoins, appealing to crypto users interested in local impact. The platform's market presence is niche but growing, with active offerings for cities like Miami and New York City. The absence of detailed company information and contact data limits external trust signals. The use of modern web infrastructure and analytics indicates digital maturity. No partnerships or subsidiaries are explicitly identified. The platform could benefit from enhanced transparency and formalized policies to strengthen credibility.

Security posture

The website demonstrates a basic to moderate security posture with HTTPS enforced and no visible sensitive data leaks. However, it lacks important security headers such as Content-Security-Policy and X-Frame-Options, which are recommended to mitigate common web attacks. There is no public security policy, incident response information, or vulnerability disclosure program visible, which are important for user trust and compliance. The use of third-party scripts and analytics requires ongoing monitoring to avoid supply chain risks. GDPR compliance indicators are minimal, with no explicit privacy or cookie policies found. Overall, the security maturity is adequate for a small crypto platform but requires improvements to meet higher compliance and security standards.

Recommendations

  1. Publish comprehensive privacy and cookie policies to improve GDPR compliance and user trust.
  2. Implement and configure security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Provide clear contact information including security incident response and abuse contacts.
  4. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  5. Enhance accessibility features and conduct regular security audits of third-party dependencies.

Technical notes

Notes

The website is built on Webflow CMS with integration of Google Fonts and jQuery libraries. It uses Cloudflare Web Analytics and Fathom Analytics for traffic monitoring. The site is mobile optimized with responsive design and good SEO meta tags. Hosting is likely via Webflow with Cloudflare CDN, providing moderate performance. No major technical debt or deprecated technologies detected. However, the absence of advanced security headers and formal compliance documentation indicates areas for modernization. The site’s JavaScript and CSS are minified and well-structured, supporting good user experience. Overall, the technical infrastructure is solid for a small to medium crypto platform but can be enhanced with improved security and compliance features.
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.
