The company facilitates buying and selling of cryptocurrencies such as Bitcoin, Ether, XRP, and Bitcoin Cash using the iDEAL payment method. SATOS partners with Bybit.com to provide customers access to over 300 cryptocurrencies and offers wallet services without holding user accounts, emphasizing a security-first approach.

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

5 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 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

SATOS operates in the competitive Dutch cryptocurrency market, leveraging a partnership with Bybit.com to expand its service offerings. Its business model focuses on facilitating fiat-to-crypto transactions and wallet services without custodial accounts, appealing to users valuing self-custody and security. The company targets retail crypto buyers and sellers in the Netherlands, emphasizing ease of use and regulatory compliance. The presence of DNB registration and transparent business information strengthens its market position. The partnership ecosystem includes Bybit as a critical service provider for trading infrastructure. Growth indicators include active content updates and multilingual support. Strategic observations suggest SATOS benefits from combining local regulatory trust with global crypto platform capabilities.

Security posture

The website demonstrates a mature security posture with HTTPS enforced, use of Google reCAPTCHA v3 for bot mitigation, and a comprehensive cookie consent mechanism aligned with GDPR requirements. No exposed sensitive data or vulnerable scripts were detected in the HTML content. However, the absence of explicit security headers like X-Frame-Options and a dedicated security policy page indicates room for improvement. Incident response contact information is not publicly available, which could hinder timely reporting and resolution of security issues. Overall, the security culture appears proactive but could benefit from formalized policies and transparency to enhance user trust and compliance with evolving regulations such as NIS2.

Recommendations

  1. Implement and verify standard security headers including X-Frame-Options, X-Content-Type-Options, and Content-Security-Policy.
  2. Publish a dedicated security policy and incident response contact information on the website.
  3. Regularly audit and update third-party plugins and scripts to mitigate vulnerabilities.
  4. Enhance accessibility features to improve compliance and user experience for all users.
  5. Consider publishing data retention policies and transparency reports to strengthen privacy compliance.

Overall, the technical infrastructure supports a professional and secure user experience aligned with business goals.
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.
