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

Crossmint, Inc. operates a sophisticated fintech platform specializing in wallet infrastructure, stablecoin payments, tokenization, and agentic commerce solutions. Positioned as a trusted provider for over 40,000 enterprises and developers, Crossmint offers a comprehensive suite of API-driven financial services designed to integrate stablecoin and crypto rails seamlessly. Their market presence is reinforced by partnerships with major financial and technology companies and backing from prominent venture capital firms. Technically, the website leverages modern web technologies including Webflow CMS, Google Fonts, Datadog RUM, PostHog analytics, and advanced JavaScript libraries such as GSAP and Splide.js. The platform demonstrates excellent performance, mobile optimization, and accessibility, reflecting a mature digital infrastructure. The use of multiple analytics and tracking tools indicates a data-driven approach to user engagement and product improvement. From a security perspective, Crossmint maintains a strong posture with HTTPS enforcement, SOC2 and VASP compliance, GDPR and CCPA adherence, and a responsible disclosure policy. Security headers and reCAPTCHA integration further enhance protection. However, the absence of publicly available WHOIS data introduces a minor trust concern, though the overall security and compliance indicators are robust. Overall, Crossmint presents a low-risk profile with a professional, secure, and compliant online presence. Strategic recommendations include publishing a security.txt file, enhancing incident response contact visibility, and disclosing Data Protection Officer information to further strengthen trust and compliance.

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 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 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 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

Crossmint is strategically positioned in the fintech and blockchain sectors, targeting enterprises and developers seeking to integrate stablecoin and crypto payment solutions. Their B2B SaaS model focuses on API and widget-based financial infrastructure, enabling rapid deployment and scalability. The company benefits from strong venture capital backing and partnerships with industry leaders, which enhances credibility and market reach. Their product portfolio addresses critical needs in wallet infrastructure, authentication, tokenization, and payments, catering to emerging trends in digital finance and agentic commerce. Growth indicators include extensive case studies, a broad client base, and continuous product innovation. The partnership ecosystem and compliance certifications provide competitive advantages in a regulated environment.

Security posture

Crossmint exhibits a mature security posture with multiple compliance certifications including SOC2 II, VASP, GDPR, and CCPA. The website enforces HTTPS and implements security headers to mitigate common web vulnerabilities. Use of reCAPTCHA on forms and a cookie consent mechanism demonstrate attention to user data protection and bot mitigation. The presence of a vulnerability disclosure policy indicates readiness for incident response. However, the lack of WHOIS transparency and absence of a security.txt file are areas for improvement. No critical vulnerabilities or exposed sensitive data were detected. Overall, the security culture appears strong, aligned with enterprise-grade expectations.

Recommendations

  1. Publish a security.txt file to facilitate vulnerability reporting and improve transparency.
  2. Disclose Data Protection Officer contact details to enhance GDPR compliance and user trust.
  3. Regularly audit and update third-party libraries to mitigate potential vulnerabilities.
  4. Increase visibility of incident response contacts and procedures on the website.
  5. Maintain and renew compliance certifications and communicate updates to stakeholders.

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.
