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

BestChange operates as a well-established online directory and monitoring platform for cryptocurrency, fiat, and e-currency exchangers. It provides users with real-time exchange rates, trusted exchanger listings, and referral opportunities, positioning itself as a reliable intermediary in the digital currency exchange market. The platform targets both individual users and businesses seeking efficient and secure currency conversion solutions. Technically, the website employs standard web technologies including JavaScript, CSS, and integrates Google Tag Manager for analytics and hCaptcha for bot mitigation, reflecting a moderate level of digital maturity. Security-wise, the site enforces HTTPS and uses CAPTCHA to prevent automated abuse, but lacks visible security headers and explicit privacy or cookie policies, which are areas for improvement. The absence of WHOIS registration data is a notable concern, although the website's content and longevity suggest legitimacy. Overall, the site presents a professional and trustworthy interface with room to enhance privacy 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

4 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 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

    • 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

  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

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

BestChange holds a strong market position as a trusted aggregator in the cryptocurrency exchange sector, leveraging a business model centered on providing comprehensive exchange rate monitoring and vetted exchanger referrals. Its revenue streams likely include affiliate commissions from exchangers and possibly advertising. The platform's long operational history and extensive exchanger network indicate stable growth and a broad user base. The referral program and detailed exchanger statistics enhance user engagement and trust. However, the lack of explicit company contact details and privacy documentation may limit institutional partnerships and regulatory compliance. Strategic partnerships with payment processors or financial institutions could further solidify its market presence.

Security posture

The website demonstrates a baseline security posture with HTTPS enforcement and bot protection via hCaptcha. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces its defense-in-depth. No explicit incident response or vulnerability disclosure mechanisms are visible, which could hinder timely mitigation of security issues. Privacy compliance indicators are minimal, with no visible GDPR statements or cookie consent mechanisms. The missing WHOIS data raises questions about domain registration transparency, which is a potential risk factor. Enhancing security headers, publishing privacy and cookie policies, and establishing clear incident response contacts would significantly improve the security maturity.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies with GDPR compliance details.
  2. Add security headers (Content-Security-Policy, X-Frame-Options, X-Content-Type-Options) to strengthen protection against common web attacks.
  3. Provide clear contact information for security incidents and general inquiries to improve trust and incident response readiness.
  4. Verify and disclose domain registration details to enhance legitimacy and user confidence.
  5. Improve mobile optimization and accessibility to broaden user reach and comply with best practices.

Technical notes

Notes

The website uses a traditional web stack with HTML, CSS, and JavaScript, including external scripts for analytics (Google Tag Manager) and bot protection (hCaptcha). The site appears to be custom-built without a common CMS, indicating tailored development. Performance is moderate with some room for optimization, especially for mobile devices where responsiveness is basic. SEO is well addressed through meta tags and structured navigation. The lack of modern frameworks or platforms suggests potential technical debt but also simplicity that may aid stability. Opportunities exist to modernize the tech stack, enhance accessibility, and implement advanced security 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.
