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

ExchangeSumo is an established online platform specializing in monitoring and rating electronic money and cryptocurrency exchangers, primarily serving Russian and Ukrainian speaking users. The website offers real-time exchange rate updates, cashback offers, and a comprehensive search for exchange directions, positioning itself as a trusted resource in the finance sector since 2012. The domain, registered in 2018, aligns well with the business's operational history and market presence. Technically, the site employs modern web technologies including jQuery, Bootstrap, and multiple analytics tools, ensuring a responsive and user-friendly experience across devices. Security-wise, the site enforces HTTPS and uses Cloudflare DNS but lacks DNSSEC and explicit security policies, indicating room for improvement in security posture. Privacy compliance is partial, with no visible cookie consent mechanism or GDPR-specific disclosures. Overall, ExchangeSumo presents a professional and functional service with moderate risk, suitable for users seeking currency exchange information in its target regions.

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.

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

  • Security headers: did not complete in this scan.
  • 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

The platform operates in the finance and technology sectors, focusing on currency exchange monitoring and cryptocurrency services. Its business model revolves around providing updated exchange rates, ratings, and cashback incentives to attract and retain users. The target audience includes individuals and businesses involved in currency exchange, particularly in Russian-speaking countries. The website's market position is strengthened by its longevity and comprehensive service offerings. While direct contact details are limited to a contact form, the presence of a Telegram channel and YouTube link supports community engagement and marketing efforts. The absence of explicit certifications or security policies suggests a focus on service delivery over formal compliance frameworks.

Security posture

ExchangeSumo demonstrates a basic to moderate security maturity level. The use of HTTPS and Cloudflare DNS provides foundational security, but the lack of DNSSEC and missing security headers like Content-Security-Policy reduce its defense-in-depth. No security.txt or incident response contacts are published, limiting transparency in vulnerability management. The site collects user data via forms and tracking scripts but lacks visible cookie consent mechanisms, potentially impacting GDPR compliance. No critical vulnerabilities or exposed sensitive data were detected in the analysis. Enhancing security policies, implementing DNSSEC, and adding cookie consent would significantly improve the security posture.

Recommendations

  1. Enable DNSSEC to enhance DNS security and prevent spoofing.
  2. Publish a clear security policy and provide incident response contact information.
  3. Implement a cookie consent banner to comply with GDPR and improve user privacy transparency.
  4. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy risks and potential vulnerabilities.

Technical notes

Notes

The website uses a modern tech stack including jQuery and Bootstrap for UI, with multiple analytics platforms integrated for user behavior tracking. Hosting details are not explicit, but DNS is managed via Cloudflare, indicating a reliable DNS infrastructure. Performance is moderate with good mobile optimization and SEO practices evident through meta tags and structured data. Accessibility is basic, with potential for improvement in ARIA roles and keyboard navigation. The site does not appear to use a common CMS, suggesting a custom or proprietary platform. Technical risks include reliance on multiple third-party scripts which may introduce vulnerabilities or privacy concerns if not properly managed.
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.
