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 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

ChangeNOW operates in the finance and technology sectors, focusing on cryptocurrency exchange and management. Its business model revolves around instant crypto swaps with low fees, fiat integration, and value-added services like staking and loans. The company targets a broad audience from individual crypto users to businesses requiring API and white label solutions. Its ecosystem includes partner services such as wallet apps, payment gateways, and blockchain infrastructure providers, enhancing its market reach and service diversity. The company shows growth potential through continuous product expansion and strong community engagement via social media and affiliate programs.

Security posture

The platform exhibits a mature security posture with enforced HTTPS, Cloudflare protection, and non-custodial operations that reduce risk exposure. Error tracking via Sentry and support for two-factor authentication indicate proactive security management. However, the absence of a public security policy, incident response documentation, and vulnerability disclosure program are gaps that could be addressed to improve transparency and compliance. No critical vulnerabilities or exposed sensitive data were detected, and the platform respects user privacy by not forcing sign-ups and limiting data collection to necessary analytics.

Recommendations

  1. Enable DNSSEC to strengthen domain name security and prevent DNS spoofing.
  2. Publish a dedicated security policy and incident response plan to enhance transparency and user trust.
  3. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Review and enforce Content-Security-Policy headers to mitigate risks from third-party scripts.
  5. Continue regular audits of third-party libraries and scripts to prevent introduction of vulnerabilities.

Notes

The website is built with modern web technologies, including responsive design and progressive web app features, ensuring excellent mobile optimization and user experience. Hosting and DNS are managed via Cloudflare, providing CDN and DDoS protection. Analytics are implemented using both Universal and GA4 Google Analytics, supplemented by Sentry for error monitoring. The site uses JSON-LD structured data for SEO and rich snippets. Performance is fast with preloading of fonts and images. No CMS was explicitly detected, suggesting a custom or proprietary solution. Overall, the technical infrastructure is robust, scalable, and aligned with industry best practices.
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.
