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

6 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.

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • 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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. 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 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';…

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

YieldStreet targets accredited investors seeking diversification beyond traditional stocks and bonds. Its business model revolves around an online marketplace for alternative investments, generating revenue through investment management and brokerage services. The company maintains regulatory compliance as an SEC-registered investment adviser and broker-dealer member of FINRA and SIPC. Its ecosystem includes subsidiaries such as Yieldstreet Management, LLC and Yieldstreet Markets LLC. The platform's competitive advantage lies in its curated investment offerings, educational resources, and managed portfolio solutions. Growth indicators include active content updates, multiple investment products, and strategic partnerships with private market sponsors.

Security posture

The website exhibits a mature security posture with enforced HTTPS, comprehensive security headers, and no exposed sensitive data. The presence of detailed disclaimers and responsible disclosure policy indicates awareness of security and compliance requirements. However, the absence of a dedicated security policy page and incident response contact limits transparency. No critical vulnerabilities or outdated libraries were detected. Privacy policies and cookie consent mechanisms align with GDPR requirements. Overall, the security culture appears proactive but could benefit from enhanced public security documentation and incident response readiness.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and controls.
  2. Provide explicit incident response contact channels such as security@ or abuse@ email addresses.
  3. Implement and publish a security.txt file to facilitate vulnerability reporting.
  4. Regularly review and audit third-party scripts and dependencies for vulnerabilities.
  5. Enhance accessibility compliance to meet or exceed WCAG AA standards for inclusivity.

Technical notes

Notes

The website is built using React and Gatsby, leveraging modern JavaScript and CSS for a responsive and performant user experience. Hosting appears to be behind Cloudflare, providing CDN and security benefits. The site uses preconnect and preload hints for performance optimization and loads fonts and assets efficiently. SEO is supported by comprehensive meta tags including Open Graph and Twitter cards. Accessibility features are present but could be improved. No CMS is detected, indicating a custom-built solution. The technical infrastructure supports scalability and modern web standards, with opportunities to enhance security transparency and accessibility.
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.
