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

The Trade Desk is a leading independent demand-side platform (DSP) specializing in programmatic advertising for data-driven marketers and agencies. Their platform offers omnichannel advertising capabilities, identity solutions, audience targeting, and advanced measurement and optimization powered by artificial intelligence. The company maintains a strong market position with a comprehensive suite of services tailored to modern digital advertising needs. Technically, the website employs modern JavaScript frameworks such as Alpine.js, integrates Google Tag Manager for analytics, and uses Rollbar for error monitoring, reflecting a mature digital infrastructure. The site is fast, mobile-optimized, and well-structured, providing an excellent user experience. Security-wise, the site enforces HTTPS and uses consent mechanisms for cookies, but lacks explicit security headers and a public security policy or incident response contact, which are recommended for enhanced trust and compliance. Overall, the website is professional, trustworthy, and compliant with GDPR, though the absence of WHOIS data slightly reduces transparency. Strategic recommendations include adding security headers, publishing a security policy, and implementing a vulnerability disclosure program.

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

2 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.

    • 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

  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.

    • 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

The Trade Desk operates in the technology sector, focusing on advertising technology and programmatic buying solutions. Their business model revolves around providing a DSP platform that enables marketers to execute data-driven campaigns across multiple channels including audio, CTV/OTT, digital out-of-home, display, mobile, native, and video. The company targets advertisers, agencies, and data-driven marketers globally, with localized websites for multiple regions and languages. Their ecosystem includes partnerships with identity providers and retail data sources, enhancing targeting capabilities. The presence of dedicated investor and career portals indicates a large enterprise with structured corporate governance. The company leverages advanced AI and APIs to maintain competitive advantages and foster innovation. Their marketing and analytics tools are integrated with industry standards, supporting extensive data collection and user tracking within privacy compliance frameworks.

Security posture

The website demonstrates a solid security posture with mandatory HTTPS encryption and use of reputable analytics and error tracking services. The presence of cookie consent mechanisms aligns with GDPR requirements. However, the absence of explicit security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options represents an area for improvement. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. The lack of a published security policy or incident response contact reduces transparency and may impact user trust. Implementing a security.txt file or vulnerability disclosure program would enhance the security culture and readiness. Overall, the site is secure but could benefit from additional best practices to strengthen defenses and compliance.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options.
  2. Publish a clear security policy and provide incident response contact information on the website.
  3. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Enhance transparency around data retention policies and user privacy practices.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are used.

Technical notes

Notes

The website is built using modern web technologies including Alpine.js for reactive UI components, Vite for module bundling, and integrates third-party services such as Google Tag Manager and Rollbar. The site is well-optimized for performance and mobile responsiveness, with structured navigation and SEO-friendly meta tags. The use of asynchronous script loading and modulepreload improves load times. No CMS was detected, indicating a custom-built platform. Hosting provider details were not discernible from the content. The technical implementation reflects a mature and modern infrastructure with good practices in place, though opportunities exist to enhance security headers and formalize security policies.
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.
