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

Cryptomus is a cryptocurrency exchange and payment platform offering a variety of services including a payment gateway, wallet, staking for rewards, P2P exchange, and a cryptocurrency converter supporting multiple currencies. The platform targets cryptocurrency traders and users seeking low fees and a comprehensive crypto service ecosystem. Their market position is supported by trust signals such as Certik certification and positive Trustpilot reviews, indicating a reputable presence in the crypto finance sector. Technically, the website is built on modern frameworks such as Next.js and React, with mobile optimization and integration of Google Tag Manager and reCAPTCHA for analytics and security. However, some areas such as explicit privacy and cookie policies are missing, which impacts privacy compliance scores. Security posture is generally good with HTTPS and some best practices but lacks explicit security headers and incident response disclosures. Overall, the website is professional and trustworthy but could improve 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

6 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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

Cryptomus operates in the finance and technology sectors, focusing on cryptocurrency exchange and payment services. Their business model revolves around providing a multi-service platform that includes trading, payments, staking, and wallet management. The target customers are retail and institutional crypto users. The company leverages partnerships with security certification providers like Certik and maintains a presence on multiple social media platforms to enhance brand visibility and trust. The platform's app availability on iOS and Android indicates a strategy to capture mobile users. Growth indicators include a large number of user ratings and media mentions. The absence of detailed company registration data or physical addresses limits deeper business verification but the WHOIS data aligns with the business claims, supporting legitimacy.

Security posture

The security maturity of Cryptomus is moderate to good. The site enforces HTTPS and integrates Google reCAPTCHA to mitigate automated abuse. However, the lack of visible security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces defense-in-depth. No public security policy or incident response contact is disclosed, which is a gap for transparency and user trust. No vulnerability disclosure or security.txt file is found, limiting external security reporting. No exposed sensitive data or known vulnerable libraries were detected in the provided content. Overall, the platform demonstrates awareness of security best practices but should enhance policy transparency and technical controls to improve security posture and compliance with regulations like GDPR and NIS2.

Recommendations

  1. Publish comprehensive privacy and cookie policies with explicit GDPR compliance and consent mechanisms.
  2. Implement and disclose a formal security policy and incident response contact information.
  3. Add security headers such as CSP, HSTS, X-Frame-Options to strengthen browser security.
  4. Create and maintain a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  5. Enhance accessibility features and provide physical contact information to improve trust and compliance.

Technical notes

Notes

The website uses a modern technology stack including React and Next.js frameworks, enabling server-side rendering and good SEO. Integration with Google Tag Manager and reCAPTCHA indicates use of advanced analytics and bot protection. The site is mobile optimized with app availability on major platforms. Performance is moderate with some room for improvement in loading speed and accessibility. No CMS was detected, suggesting a custom or framework-based build. Hosting provider details are not explicit. The technical implementation is solid but could benefit from enhanced security headers and accessibility improvements to reduce technical debt and risks.
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.
