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

Trustworthy Accountability Group (TAG) operates as a leading global initiative dedicated to combating criminal activity and enhancing trust and transparency within the digital advertising ecosystem. The organization provides industry-wide certification programs, threat intelligence sharing, and brand safety initiatives, positioning itself as a key player in the media sector. TAG's website reflects a mature digital presence with comprehensive content, professional design, and clear navigation aimed at industry stakeholders including brands, agencies, publishers, and ad tech providers. Technically, the website is built on the HubSpot CMS platform, utilizing modern web technologies such as jQuery and Google Fonts, and incorporates HubSpot analytics for user tracking. The site is mobile-optimized and demonstrates good SEO practices, although some accessibility features could be enhanced. Security posture is solid with HTTPS enforced and cookie consent mechanisms in place, but lacks explicit security headers and a published security policy or vulnerability disclosure framework. The absence of WHOIS registration data is a notable concern, as it conflicts with the otherwise professional and transparent nature of the site. This discrepancy suggests either privacy protection or a domain registration anomaly, which impacts the overall trust score. No direct company contact emails or phone numbers are publicly listed, with contact primarily facilitated through web forms. The site contains no adult or questionable content and is fully accessible without WAF or security challenges. Overall, TAG's website is a well-executed digital platform serving an essential role in the digital advertising industry, but improvements in transparency regarding domain registration and enhanced security practices are recommended to bolster trust and compliance.

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

3 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  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

  3. 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

TAG holds a strong market position as a non-profit industry initiative focused on digital advertising integrity. Its competitive advantage lies in its comprehensive certification programs and threat intelligence sharing that address fraud, malware, brand safety, and transparency. The business model revolves around membership and certification services, targeting large enterprises, brands, agencies, and technology providers in the media sector. The presence of numerous high-profile platinum members and partner logos indicates a robust partnership ecosystem and industry acceptance. Growth indicators include frequent press releases, data reports, and active community engagement. Strategic observations highlight the importance of maintaining domain registration transparency and expanding direct contact channels to enhance stakeholder trust.

Security posture

The website demonstrates a moderate to good security maturity level with enforced HTTPS, cookie consent, and no visible exposure of sensitive data. However, the lack of security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options reduces its defense-in-depth posture. No vulnerability disclosure policy or security.txt file is published, limiting external security collaboration. Compliance with GDPR is indicated through privacy and cookie policies. Incident response readiness and security culture indicators are not explicitly documented. The domain registration opacity is a significant compliance and trust gap. Overall, the security posture is adequate but would benefit from enhanced header implementation, explicit security policies, and improved transparency.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection to strengthen site security.
  2. Publish a clear security policy and vulnerability disclosure framework, including a security.txt file, to facilitate responsible reporting and improve trust.
  3. Clarify domain registration details or use verified WHOIS privacy protection to resolve inconsistencies and enhance legitimacy.
  4. Provide direct company contact emails and phone numbers to improve communication channels and business credibility.
  5. Enhance accessibility features to meet higher standards and improve user experience for all visitors.

Technical notes

Notes

The website is built on the HubSpot CMS platform, leveraging standard web technologies such as jQuery 1.7.1 and Google Fonts for typography. It uses HubSpot's analytics and marketing tools, including cookie consent banners, indicating a mature marketing infrastructure. Performance is moderate with room for optimization, particularly in loading speed and accessibility compliance. The site is mobile responsive and SEO optimized with proper meta tags and Open Graph data. However, the use of an older jQuery version may pose security risks and modernization opportunities exist. The hosting and platform choice provide stability but limit customization. Overall, the technical infrastructure supports the business needs effectively but could be improved with updated libraries and enhanced security configurations.
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.
