Security score

Risk levelMedium

0–100, higher is better. How it is calculated

DUOMAI is a well-established affiliate marketing platform founded in 2010, serving over 2000 brands globally with a focus on performance marketing and diversified media resources. The website demonstrates a professional design and clear business focus targeting brands, publishers, and influencers. Technically, the site uses modern frameworks such as React and Next.js, with integrations like Google Tag Manager and Tencent's TCaptcha for analytics and security. Security posture is moderate with HTTPS enabled and domain status protections, but lacks DNSSEC and security headers. Privacy compliance is weak due to missing privacy and cookie policies. Overall, the site is accessible and trustworthy but would benefit from enhanced privacy and security practices.

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. 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 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

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

DUOMAI operates in the e-commerce sector as an affiliate marketing network with a large scale and global reach. Its competitive advantages include a decade of industry experience, a large brand portfolio, and a diversified media network. The business model centers on performance marketing, connecting brands with publishers and influencers to drive sales conversions. The company targets global markets, with a strong presence in China and international regions. The partnership ecosystem includes mini programs and Walmart seller programs, indicating diversified service offerings. Growth indicators are positive given the extensive brand cooperation and media diversity.

Security posture

The website employs HTTPS and domain registration protections, indicating a baseline security maturity. However, the absence of DNSSEC and security headers such as Content-Security-Policy and X-Frame-Options suggests room for improvement. No visible vulnerabilities or exposed sensitive data were detected. The lack of published security policies or incident response contacts limits transparency and preparedness. Analytics tracking is present but without explicit user consent mechanisms, which may pose compliance risks. Overall, the security posture is moderate but should be enhanced to meet best practices and regulatory requirements.

Recommendations

  1. Enable DNSSEC to protect against DNS spoofing and improve domain security.
  2. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Publish clear privacy and cookie policies with user consent mechanisms to improve GDPR compliance.
  4. Add incident response and vulnerability disclosure information to enhance transparency and trust.
  5. Regularly audit analytics and tracking implementations to ensure privacy compliance and minimize data collection risks.

Technical notes

Notes

The website is built on a modern React and Next.js stack, leveraging Ant Design icons and asynchronous loading of scripts for performance. Google Tag Manager is used for analytics, and Tencent's TCaptcha is integrated for bot protection. The site is mobile-optimized with responsive design elements and preloaded images for faster rendering. However, no CMS or hosting provider details were detected. Performance is moderate with room for optimization in accessibility and SEO. The technical infrastructure supports a professional user experience but could benefit from enhanced security configurations and privacy features.
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.
