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. 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 Cookie Policy found

      GDPR requires clear information about cookie usage

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

  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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1
    • 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

Coinmate holds a competitive advantage as the largest Czech crypto exchange with a decade-long history and unique fiat markets in EUR and CZK. Its business model revolves around providing accessible cryptocurrency trading services to both beginners and advanced users, supported by features like quick buy, dollar-cost averaging, and a professional trading platform integrated with TradingView. Revenue streams likely include trading fees and premium services. The company targets European retail and institutional investors, supported by multilingual customer service and educational content. Strategic partnerships with local financial institutions and fintech associations enhance its ecosystem credibility. Media coverage in reputable outlets further strengthens its market presence. The affiliate program indicates active marketing efforts to expand user base. Overall, Coinmate demonstrates sustainable growth potential and solid operational foundations.

Security posture

Coinmate exhibits a mature security posture with multiple layers of protection. The platform uses HTTPS exclusively, enforces two-factor authentication, and maintains segregated client funds to prevent misuse. Its custody infrastructure is described as state-of-the-art, comparable to banking standards. The ISO/IEC 27001:2022 certification confirms adherence to internationally recognized information security management practices. However, the absence of publicly disclosed incident response or vulnerability disclosure policies and lack of explicit security contact emails represent areas for improvement. The use of third-party scripts and analytics is managed with consent mechanisms, mitigating privacy risks. No obvious vulnerabilities or exposed sensitive data were detected in the analysis. Security headers and SSL configurations are robust, contributing to a high security score. Recommendations include publishing incident response details and enabling DNSSEC to further enhance domain security.

Recommendations

  1. Publish a dedicated incident response and vulnerability disclosure policy page with clear contact channels.
  2. Add explicit security contact emails such as security@coinmate.io or abuse@coinmate.io for reporting issues.
  3. Enable DNSSEC on the domain to protect against DNS spoofing and improve domain security.
  4. Regularly audit and update third-party scripts and analytics tools to minimize potential vulnerabilities.
  5. Enhance transparency by providing detailed data retention policies and privacy impact assessments.

Technical notes

Notes

The website is built on a modern Angular framework (version 19), utilizing advanced front-end technologies and integrations such as TradingView for charting and Microsoft Clarity for user behavior analytics. Hosting and DNS services are provided by Cloudflare, ensuring performance optimization and security. The site is mobile-optimized with responsive design and accessibility considerations.

Cookie consent is managed via Cookiebot, supporting GDPR compliance. Performance is fast with asynchronous loading of scripts and minimal blocking resources. The technical stack is current and well maintained, indicating low technical debt and good digital maturity. Opportunities exist to improve by integrating more explicit security and privacy documentation and enabling DNSSEC.
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.
