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

NBCUniversal Media is a leading global media and entertainment company specializing in the development, production, and marketing of entertainment, news, and information content. As a subsidiary of Comcast Corporation, NBCUniversal operates a diverse portfolio of brands including NBC, NBC News, NBC Sports, Peacock streaming service, Telemundo, and Universal theme parks. The company targets a broad global audience with a comprehensive range of media offerings across multiple platforms. Technically, the website is built on Drupal 10 CMS and leverages modern web technologies such as jQuery, FontAwesome, Datadog RUM for real user monitoring, and OneTrust for cookie consent management. The site demonstrates good mobile optimization, accessibility, and SEO practices, with a professional design and clear navigation structure. From a security perspective, the site enforces HTTPS with strong SSL configuration and employs cookie consent mechanisms compliant with GDPR. While some standard security headers are present, there is room for improvement by adding additional headers like Content-Security-Policy. No critical vulnerabilities or exposed sensitive data were detected. The absence of a security.txt or explicit incident response contacts suggests an area for enhancement. Overall, NBCUniversal's website reflects a mature digital presence with strong privacy compliance and business credibility. The site is trustworthy, well-maintained, and aligned with the company's market position. Strategic recommendations include enhancing security headers, publishing vulnerability disclosure information, and improving visibility of security contact channels 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.

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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  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

NBCUniversal holds a dominant position in the media and entertainment industry, leveraging a diversified portfolio of brands and content distribution channels. Its business model focuses on content creation, broadcasting, streaming, and experiential offerings such as theme parks. The company benefits from its parent Comcast Corporation's resources and scale. NBCUniversal targets a wide demographic including general entertainment consumers, sports fans, news audiences, and Spanish-language viewers through Telemundo. The extensive brand ecosystem and partnerships support growth and market penetration. The website's content and linked domains reflect a coherent and integrated brand strategy, reinforcing NBCUniversal's competitive advantages and market leadership.

Security posture

The website exhibits a solid security posture with enforced HTTPS and use of modern monitoring tools like Datadog RUM. Cookie consent is managed via OneTrust, providing granular user control and GDPR compliance. Security best practices such as masking user input in session replay and tracking long tasks are implemented. However, the site lacks some recommended HTTP security headers (e.g., Content-Security-Policy, X-Content-Type-Options) which could mitigate risks like cross-site scripting and MIME sniffing. No exposed credentials or vulnerabilities were found in the HTML content. The absence of a published security policy or incident response contact limits transparency in security incident handling. Overall, the security maturity is good but can be improved with additional controls and disclosures.

Recommendations

  1. Implement additional HTTP security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options.
  2. Publish a security.txt file to provide clear vulnerability disclosure and incident response information.
  3. Enhance visibility of security contact channels such as security@ or abuse@ email addresses on the website.
  4. Regularly audit and update third-party scripts and cookie vendors to minimize privacy and security risks.
  5. Maintain and communicate clear data retention policies and privacy compliance updates to users.

Technical notes

Notes

The website is built on Drupal 10 CMS, indicating a modern and scalable content management platform. It uses jQuery and FontAwesome for UI components and icons, and integrates Datadog RUM for real user monitoring and performance analytics. OneTrust manages cookie consent, ensuring compliance with privacy regulations. The site is mobile optimized and accessible, with responsive design and skip links for screen readers. Performance is moderate, with asynchronous loading of scripts and optimized images. The technical stack is robust and well-maintained, though opportunities exist to enhance security headers and streamline third-party dependencies to reduce potential attack surface.
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.
