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

3 findings rated critical or high. Fix these first.

  1. 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

  2. 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
    • High

      SSL Certificate Expires Soon

      SSL certificate expires in 14 days

      What to do: Renew SSL certificate before expiration

      • NIS2 21(2)(h)
      • IR 2024/2690 9.2(c): Implementing Regulation (EU) 2024/2690, Annex point 9.2(c): Cryptography
      • NIST SC-17: NIST SP 800-53 Rev. 5 SC-17: Public Key Infrastructure Certificates

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

Blink's business model centers on providing a Bitcoin Lightning wallet and related services, including merchant POS solutions and developer APIs. The company leverages partnerships with Bitcoin communities worldwide to expand adoption. Revenue likely derives from wallet services and API usage. The target audience includes Bitcoin enthusiasts, merchants, and developers. The company maintains a consistent brand and strong community trust signals, with active social media engagement and educational content. The partnership with Galoy.io indicates a solid technology foundation. Growth indicators include multilingual support and active merchant onboarding.

Security posture

The website exhibits a mature security posture with enforced HTTPS, comprehensive security headers, and cookie consent management aligned with GDPR. No exposed sensitive data or vulnerable libraries were detected. However, the absence of a published security policy, incident response plan, and vulnerability disclosure program represents gaps in transparency and readiness. The site uses Google Tag Manager responsibly with consent updates. Overall, the security posture is good but could be enhanced by formalizing and publishing security governance documents.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and controls.
  2. Develop and disclose an incident response plan with contact channels for security issues.
  3. Implement a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Consider appointing and publishing Data Protection Officer contact information to enhance GDPR compliance.
  5. Regularly review and audit third-party scripts and dependencies to mitigate supply chain risks.

Hosting is via Amazon CloudFront CDN, ensuring fast content delivery. The site is mobile-optimized with responsive design and accessibility features.

Opportunities exist to enhance security documentation and incident response readiness to reduce operational 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.
