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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Twitter

      What to do: Document all third-party data sharing in your privacy policy

  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 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

Suno operates in the AI music technology sector, targeting a broad audience of music creators and enthusiasts. Its business model centers on providing AI-driven music generation and sharing services, positioning itself as an innovative player in the creative technology market. The company benefits from a consistent brand presence and active social media engagement, which supports community building and user acquisition. While the company appears small in size, its long domain age and comprehensive digital presence indicate stable operations. The absence of parent or subsidiary companies suggests an independent operation focused on niche AI music solutions. The integration of marketing and analytics tools like AppsFlyer and Singular indicates a data-driven approach to growth and user engagement.

Security posture

The website exhibits a mature security posture with enforced HTTPS, use of authentication frameworks, and bot protection via hCaptcha. However, the lack of DNSSEC and absence of explicit security headers such as Content-Security-Policy and Strict-Transport-Security represent areas for improvement. No vulnerabilities or exposed sensitive data were detected in the analysis. The absence of a published security policy or incident response contact limits transparency in security governance. Privacy policies and cookie consent mechanisms are well implemented, supporting GDPR compliance. Overall, the security maturity is good but could be enhanced by formalizing security documentation and improving DNS security.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement and verify security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Publish a dedicated security policy page and provide clear incident response contact information.
  4. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Continue monitoring third-party scripts and SDKs for vulnerabilities and update regularly.

Technical notes

Notes

The website is built on a modern React and Next.js stack, utilizing Chakra UI for UI components and Clerk.js for authentication. It integrates multiple third-party SDKs for analytics and marketing, including AppsFlyer, Singular, and Google Tag Manager. Hosting and DNS services are provided by Cloudflare, ensuring fast content delivery and DNS resolution. The site is optimized for mobile devices and demonstrates excellent performance and SEO practices. No CMS was detected, indicating a custom or framework-based build. The technical infrastructure is robust, though the absence of DNSSEC and some security headers suggests room for technical security enhancements.
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.
