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's market positioning is that of an essential media measurement provider with a broad product portfolio that addresses multiple verticals within media and advertising. Their competitive advantage lies in their cross-platform measurement capabilities and integration of diverse data sources to deliver actionable insights. Revenue streams are likely derived from subscription-based analytics services, licensing of measurement data, and programmatic targeting solutions. The target customer segments include advertisers, media agencies, broadcasters, and digital content providers. Growth indicators include expansion into programmatic targeting via their subsidiary Proximic and continuous updates to their analytics offerings, including AI tool usage data. The partnership ecosystem includes integrations with platforms like PubMatic and Eloqua, enhancing their market reach and service capabilities.

Security posture

The website demonstrates a moderate security maturity level with several security headers implemented such as Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and X-XSS-Protection. However, critical gaps exist in the SSL/TLS configuration, as no valid certificate is detected and no TLS protocols are enabled, which severely impacts secure communications. HSTS is declared but not enforced, and OCSP stapling is absent. There is no evidence of a published vulnerability disclosure or incident response contact, which could hinder timely security issue reporting and resolution. Privacy compliance is supported by a cookie consent mechanism and a comprehensive privacy policy indicating GDPR adherence. Overall, while some best practices are observed, the lack of proper HTTPS implementation is a significant vulnerability that should be addressed promptly.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate to enable HTTPS across the site.
  2. Enable TLS 1.2 or higher protocols and disable insecure protocols to secure data in transit.
  3. Enforce HSTS with includeSubDomains and preload directives to prevent protocol downgrade attacks.
  4. Implement OCSP stapling to improve certificate revocation checking performance and security.
  5. Publish a vulnerability disclosure policy and provide clear incident response contact channels.
  6. Regularly audit and update third-party libraries and scripts to mitigate vulnerabilities.
  7. Enhance accessibility features to improve compliance and user experience for all users.

Technical notes

Notes

The website is built on a modern technology stack including eZ Platform Enterprise CMS, Bootstrap framework, and various JavaScript libraries such as jQuery and Google Charts. Hosting is provided via AWS CloudFront CDN, ensuring global content delivery. Performance metrics indicate slow loading times, possibly due to unoptimized resources or server response delays. Mobile optimization is good with responsive design elements and alternate language support. SEO is well addressed with proper meta tags, Open Graph data, and structured JSON-LD schema for organization details. Technical debt is minimal but the lack of SSL/TLS is a critical risk. Opportunities exist to improve performance and security configurations to enhance overall site reliability and 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.
