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

1 finding rated critical or high. Fix these first.

  1. 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

SupplierOne targets suppliers and corporate buyers in the procurement sector, focusing on supplier diversity and small business sourcing. Its business model revolves around supplier registration and intelligence services, facilitating connections between suppliers and buyers. The platform's market position is strong as a trusted supplier intelligence provider with a comprehensive database and analytics. The company was founded in 2015 and operates primarily in the United States. Partnerships with Zendesk and HubSpot enhance customer support and marketing capabilities. The absence of direct contact emails or phone numbers suggests reliance on web forms and support portals for communication.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, use of anti-CSRF tokens, and Cloudflare Bot Management. Cookie consent and privacy policies align with GDPR requirements. However, the lack of DNSSEC and some security headers like Content-Security-Policy and Referrer-Policy represent areas for improvement. No vulnerabilities or exposed sensitive data were detected. Incident response and security policy information are not publicly available, indicating potential gaps in transparency. Overall, the security measures are adequate for the business type but could be enhanced to meet higher standards.

Recommendations

  1. Enable DNSSEC to strengthen DNS security and prevent spoofing.
  2. Implement Content-Security-Policy and Referrer-Policy headers to improve protection against XSS and privacy leaks.
  3. Publish a clear security policy and incident response plan to increase transparency and trust.
  4. Regularly audit third-party scripts and dependencies to mitigate vulnerabilities.
  5. Consider adding direct contact information for security and incident reporting.

Technical notes

Notes

The website uses a robust technology stack including jQuery, Bootstrap, Select2, and various plugins for UI and analytics. It is hosted behind Cloudflare, providing DNS and security benefits. The site is mobile optimized and accessible with WCAG considerations. Performance is moderate, with room for optimization. The use of ASP.NET backend is inferred from cookies and tokens. Integration with HubSpot and Zendesk supports marketing and customer service. No CMS detected, indicating a custom or proprietary platform. Technical debt appears low, but enabling DNSSEC and additional security headers would modernize the infrastructure further.
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.
