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

Comscore, Inc. is a leading media measurement and analytics company founded in 1999, providing trusted cross-platform audience and advertising measurement services. The company serves media buyers, sellers, advertisers, and marketers by offering comprehensive data solutions that enable planning, transacting, and evaluating media performance across digital, television, social, and programmatic platforms. Comscore holds a strong market position as a trusted currency in the media industry with a broad portfolio of services including advertising measurement, digital audience analytics, marketing impact, and box office performance tracking. Technically, the website employs a modern technology stack including jQuery, Bootstrap, Google Tag Manager, and Google Charts, delivering a responsive and well-structured user experience. The site is optimized for mobile devices and accessibility, with good SEO practices and clear navigation. The presence of structured data enhances search engine understanding and branding consistency. From a security perspective, the site enforces HTTPS and implements cookie consent mechanisms, demonstrating compliance with privacy regulations such as GDPR. However, the absence of visible security headers and a public incident response contact or vulnerability disclosure program suggests areas for improvement. The WHOIS data is unavailable, which slightly impacts trust but is likely due to registry restrictions rather than malicious intent. Overall, Comscore's website reflects a professional, secure, and privacy-conscious digital presence aligned with its business objectives. Strategic recommendations include enhancing security headers, publishing incident response information, and adding vulnerability disclosure details to further strengthen 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.

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

Comscore operates in the media sector as an essential entity providing cross-platform audience measurement and advertising analytics. Its competitive advantage lies in its trusted currency status and comprehensive data solutions that integrate multiple media types and platforms. The business model focuses on data-driven insights for media planning, buying, and evaluation, targeting advertisers, media companies, and marketers globally. Revenue streams likely include subscription services, data licensing, and analytics tools. The company demonstrates growth through subsidiary services like Proximic and maintains a strong partnership ecosystem. Its market presence is reinforced by investor relations, press releases, and active social media engagement, indicating a mature and stable operation.

Security posture

Comscore exhibits a mature security posture with enforced HTTPS, cookie consent compliance, and privacy policy transparency. The website does not expose sensitive data and uses reputable analytics and marketing tools. However, the lack of explicit security headers such as Content-Security-Policy and absence of a public incident response or vulnerability disclosure program indicate gaps in security maturity. No critical vulnerabilities or malware indicators were detected. Compliance with GDPR is evident, but further enhancements in security communication and technical controls would improve resilience and stakeholder trust.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Publish a dedicated incident response page with clear security contact information to improve transparency and readiness.
  3. Establish and publicize a vulnerability disclosure or security.txt file to encourage responsible reporting and improve security posture.
  4. Regularly audit third-party scripts and libraries to ensure no vulnerable components are in use.
  5. Enhance data retention and privacy policy disclosures to align with evolving regulations and user expectations.

Technical notes

Notes

The website is built on a solid technical foundation using modern JavaScript libraries such as jQuery and Bootstrap for responsive design, Google Tag Manager for analytics management, and Google Charts for data visualization. The site loads scripts asynchronously to optimize performance and employs cookie consent banners for privacy compliance. While the hosting provider is not explicitly identified, the use of Google services and CDN-hosted scripts suggests a reliable infrastructure. Performance is moderate with good mobile optimization and accessibility features. Opportunities exist to improve technical SEO and security header implementation to reduce risk and enhance user trust.
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.
