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

The Trade Desk, Inc. operates a sophisticated advertising technology platform focused on targeted advertising and user privacy controls. The website adsrvr.org serves as a data access portal providing users with clear instructions to opt out of targeted advertising and control their personal information usage. The company is positioned as a leading enterprise in the programmatic advertising industry, with a strong emphasis on compliance and transparency regarding user data. Technically, the website employs modern JavaScript libraries such as jQuery 3.7.1 and integrates New Relic for performance monitoring. The site is moderately optimized for performance and mobile use, though accessibility and SEO could be improved. The domain is well-protected with multiple WHOIS status flags, though DNSSEC is not enabled, and security headers are not explicitly detected. From a security perspective, the site demonstrates good practices in domain registration and user privacy transparency but lacks published security policies, incident response contacts, and vulnerability disclosure mechanisms. No critical vulnerabilities or suspicious patterns were detected. Privacy compliance is strong with a comprehensive privacy policy and clear opt-out instructions, though a cookie consent mechanism is absent. Overall, the website presents a professional and trustworthy front with moderate technical maturity and a solid security posture. Strategic improvements in security headers, DNSSEC, and published security policies would enhance trust and compliance further.

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. 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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  3. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Potential Subdomain Takeover

      Subdomain api.adsrvr.org points to unregistered service ttd-east-desk-thetradedesk-com-761682349.us-east-1.elb.amazonaws.com

      What to do: Remove or fix CNAME record to prevent subdomain takeover

      • WSTG-CONF-10
      • NIS2 21(2)(i)
      • IR 2024/2690 12.4: Implementing Regulation (EU) 2024/2690, Annex point 12.4: Asset inventory

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

The Trade Desk holds a strong market position as an enterprise-level advertising technology provider specializing in programmatic advertising and data privacy solutions. Their business model revolves around offering advertisers tools to target audiences effectively while providing consumers with control over their personal data. The company targets advertisers and privacy-conscious users, leveraging partnerships with industry self-regulatory bodies to enhance transparency. The domain age and WHOIS data align with the company's founding date, supporting credibility. The absence of direct contact information on this page suggests a focus on self-service privacy controls rather than direct customer support here. The company’s ecosystem includes partnerships with major opt-out platforms and identity providers like LiveRamp and UID2, indicating a broad industry integration.

Security posture

The security posture is moderate with strong domain registration protections and no DNS privacy protection, which supports transparency. However, the lack of DNSSEC and missing security headers such as CSP, HSTS, and X-Frame-Options represent areas for improvement. No incident response or security policy information is publicly available on this page, which could hinder rapid response to security incidents. The use of New Relic indicates active performance monitoring but does not substitute for security monitoring. No vulnerabilities or exposed sensitive data were detected. GDPR compliance is supported by a comprehensive privacy policy and opt-out mechanisms, but cookie consent mechanisms are not implemented, which may be a compliance gap.

Recommendations

  1. Enable DNSSEC to enhance DNS security and prevent spoofing.
  2. Implement and publish comprehensive security headers (CSP, HSTS, X-Frame-Options) to mitigate common web attacks.
  3. Publish explicit security policies and incident response contacts to improve transparency and readiness.
  4. Add a cookie consent mechanism to comply fully with GDPR and ePrivacy regulations.
  5. Improve mobile optimization and accessibility to enhance user experience and compliance.

Technical notes

Notes

The website uses a modern JavaScript library (jQuery 3.7.1) and integrates New Relic for monitoring, indicating a commitment to performance tracking. The CSS and JavaScript are custom and minimal, suggesting a lightweight design. Hosting appears to be managed via MarkMonitor and NSOne DNS services, which are reputable providers. The site lacks CMS indicators, implying a custom or proprietary platform. Performance is moderate with room for improvement in mobile responsiveness and accessibility. SEO is basic, with minimal meta tags and no structured data or Open Graph tags detected. No forms are present, reducing attack surface but also limiting user interaction. Overall, the technical implementation is solid but could benefit from modernization and enhanced security 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.
