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

The Trade Desk operates a well-established advertising technology platform focused on providing targeted advertising services and comprehensive data access controls for personal information. The website analyzed serves as a data access portal, offering users clear instructions to opt out of targeted advertising and manage their privacy preferences. The company is positioned as a significant player in the digital advertising industry with a large operational scale and a founding date consistent with its domain registration. Technically, the website employs modern web technologies such as jQuery and New Relic for performance monitoring. The site is moderately optimized for mobile and accessibility, with a clean and professional design. However, some improvements could be made in SEO and explicit cookie consent mechanisms. The domain is protected with strong WHOIS status flags, although DNSSEC is not enabled, which is a recommended security enhancement. From a security perspective, the site demonstrates good practices in domain registration and cookie-based opt-out mechanisms but lacks publicly available security policies, incident response contacts, and vulnerability disclosure information. No critical vulnerabilities or security issues were detected in the content or technical setup. Privacy compliance is well addressed with a comprehensive privacy policy and clear opt-out instructions, aligning with GDPR requirements. Overall, the website presents a trustworthy and professional front for The Trade Desk’s data access and privacy controls. Strategic recommendations include enabling DNSSEC, publishing security and incident response policies, and enhancing cookie consent transparency to further strengthen security posture and user trust.

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

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 in the advertising technology sector, providing services that enable advertisers to target audiences effectively while offering consumers control over their personal data. The business model revolves around a platform that integrates data-driven advertising with privacy compliance tools. Revenue streams likely include advertising fees and data services. The target customers include advertisers, agencies, and privacy-conscious consumers. The company’s partnerships with industry self-regulatory bodies and identity providers like LiveRamp and UID2 indicate a robust ecosystem engagement. The company’s domain age and WHOIS data support its established presence and credibility in the market.

Security posture

The current security maturity level is moderate to good. The domain registration includes multiple prohibitive status flags that protect against unauthorized changes, enhancing domain security. However, the absence of DNSSEC and security headers reduces the overall security posture. No exposed sensitive data or vulnerable libraries were detected. The lack of publicly available incident response contacts and vulnerability disclosure mechanisms represents a compliance gap. Data protection practices are evident through cookie opt-out mechanisms and privacy policy adherence. Incident response readiness and security culture indicators are not publicly visible, suggesting room for improvement in transparency and user assurance.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement and publish comprehensive security policies including incident response procedures.
  3. Add explicit cookie consent banners to comply fully with privacy regulations and improve user transparency.
  4. Publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Enhance website security headers (CSP, HSTS, X-Frame-Options) to mitigate common web vulnerabilities.

Technical notes

Notes

The website uses a modern JavaScript library (jQuery 3.7.1) and integrates New Relic for performance monitoring, indicating a mature technical infrastructure. The hosting and DNS services are managed via MarkMonitor and NS1, reputable providers. The site’s performance is moderate with basic mobile optimization and accessibility features. SEO optimization is basic but functional. There is no detected CMS, suggesting a custom or proprietary platform. Technical risks include lack of DNSSEC and missing security headers, which could be addressed to reduce attack surface and improve resilience.
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.
