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.

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

Sharethrough operates in the technology and media sectors, targeting advertisers, publishers, and agencies with programmatic advertising solutions. Its business model revolves around providing proprietary ad enhancements, inventory curation, and sustainability programs to optimize ad performance and user experience. The company leverages partnerships with sustainability certification bodies and political ad registries to enhance its market credibility. Sharethrough's merger with Equativ strengthens its global presence and scale. The company emphasizes transparency, quality inventory, and sustainable advertising, positioning itself competitively in the ad tech ecosystem. Its marketing ecosystem includes advanced tracking and analytics tools, multi-language support, and a strong content strategy featuring blogs, case studies, and press releases.

Security posture

The website demonstrates a mature security posture with the implementation of key HTTP security headers such as Strict-Transport-Security, Content-Security-Policy restricting frame ancestors, and X-Frame-Options set to SAMEORIGIN. SSL certificates are valid and not self-signed, but the absence of TLS 1.2 or higher protocols is a notable gap. No known vulnerabilities such as Heartbleed or POODLE are present. The site uses secure cookies with HttpOnly and Secure flags and SameSite=None. However, DNSSEC and CAA records are not enabled, which could improve domain security. There is no visible security policy or incident response information, nor a published security.txt file. The privacy policy is comprehensive and GDPR compliant, but cookie consent mechanisms are lacking. Overall, the security score is good but could be enhanced by modernizing TLS support and improving transparency around incident response.

Recommendations

  1. Enable TLS 1.2 or higher protocols to ensure secure communications.
  2. Implement DNSSEC and CAA records to strengthen domain security and certificate issuance control.
  3. Publish a security.txt file and provide clear incident response contact information.
  4. Add a cookie consent mechanism to comply with privacy regulations and enhance user trust.
  5. Regularly review and update security headers and monitor for emerging vulnerabilities.
Technical notes

Notes

The website is built using Webflow CMS and hosted on Cloudflare CDN with AWS DNS services. It employs modern JavaScript libraries including jQuery and integrates Google Tag Manager and Google reCAPTCHA for analytics and bot protection. Multi-language support is provided via Weglot. The site demonstrates fast performance with optimized media and responsive design for mobile devices. SEO is well addressed with comprehensive metadata and Open Graph tags. However, the lack of TLS 1.2+ support and absence of DNSSEC indicate technical debt in security infrastructure. The site uses advanced ad tech features and sustainability certifications, reflecting a modern and responsible technical approach. Opportunities exist to enhance security protocols and implement additional compliance 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.
