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

BestChange.net serves as an official mirror site for BestChange.ru, a well-known Russian-language cryptocurrency exchanger monitoring platform. The service provides users with real-time exchange rates, reviews, and tools to facilitate safe and cost-effective cryptocurrency and fiat currency exchanges. The platform targets cryptocurrency users seeking reliable and transparent exchange services. Technically, the site employs standard web technologies including JavaScript, CSS, and HTML, with integration of hCaptcha for bot mitigation and Google Tag Manager for analytics. The site is accessible via HTTPS, ensuring encrypted communications. However, the absence of explicit privacy and cookie policies, as well as missing contact information, represents gaps in privacy compliance and user trust. The WHOIS data for the domain is unavailable or protected, which limits the ability to fully verify domain legitimacy. Overall, the site appears professional and functional but would benefit from enhanced transparency and compliance documentation.

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. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  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. 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';…

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 operates in the finance sector, specifically focusing on cryptocurrency exchange monitoring. Its business model revolves around aggregating and verifying exchange rates from multiple exchangers, providing users with a centralized platform to find the best rates and trusted exchangers. The platform includes features such as AML address checking, referral programs, and exchange calculators, indicating a mature service offering. The mirror domain bestchange.net supports accessibility in regions where the main site may be blocked. The company appears to have a medium-sized operation with a significant user base, evidenced by thousands of exchanger reviews and active listings. The lack of publicly available registrant data and contact details suggests a cautious approach to privacy or possible regulatory considerations.

Security posture

The website enforces HTTPS and uses hCaptcha to mitigate automated abuse, which are positive security measures. However, the absence of visible security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options indicates room for improvement in hardening the site against common web attacks. No vulnerabilities or exposed sensitive data were detected in the provided content. The lack of a published security policy or incident response contact reduces transparency and preparedness perception. Overall, the security posture is moderate but could be enhanced by implementing additional HTTP security headers, publishing security policies, and providing clear incident response channels.

Recommendations

  1. Publish comprehensive privacy and cookie policies with explicit GDPR compliance statements and consent mechanisms.
  2. Add clear contact information including support and security incident email addresses to improve user trust and incident response readiness.
  3. Implement and configure HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Regularly audit and update third-party scripts and dependencies to mitigate potential vulnerabilities.
  5. Consider publishing a security policy and vulnerability disclosure program to enhance transparency and community trust.

Technical notes

Notes

The site uses a traditional web stack with HTML, CSS, and JavaScript, including asynchronous loading of Google Tag Manager and hCaptcha scripts. The charset is windows-1251, indicating a focus on Russian language users. The site includes meta tags for viewport and SEO, canonical links, and Open Graph tags for social media sharing. The presence of a manifest file suggests some level of progressive web app support. Performance appears moderate with frequent updates of exchange rates. Mobile optimization is basic but functional. No CMS or hosting provider information was detected. The site could benefit from modernizing charset to UTF-8 and enhancing accessibility 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.
