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

NBC is a major US media and entertainment company providing television broadcasting, streaming services, and exclusive online content. The website serves as a portal for accessing full episodes, clips, schedules, and promotional material for NBC shows. It targets a broad general audience interested in entertainment and news. Technically, the site employs modern web technologies including React, Adobe DTM, mParticle, and Google Publisher Tags, hosted likely on Akamai CDN, ensuring fast performance and mobile optimization. Security posture is strong with HTTPS, security headers, and cookie consent mechanisms, though explicit security policies and incident response contacts are not publicly linked. Privacy compliance is well addressed with comprehensive privacy and cookie policies and GDPR compliance indicators. Overall, the site is professional, trustworthy, and well-branded, though WHOIS data is unavailable likely due to registry restrictions, which slightly impacts domain trust analysis.

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 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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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

NBC holds a leading position in the US media industry with a diversified portfolio including subsidiaries like Peacock, NBC Sports, and Telemundo. Its business model revolves around content creation, broadcasting, and streaming monetized through advertising and subscriptions. The company targets mass-market consumers with a wide range of entertainment and news programming. The website reflects a mature digital presence with extensive partnerships and integrations with advertising and analytics platforms. Growth indicators include active promotion of streaming content and integration with mobile apps. The partnership ecosystem includes major ad networks and analytics providers, supporting a data-driven marketing approach.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, comprehensive security headers, and cookie consent management. No vulnerabilities or exposed sensitive data were detected in the analyzed content. However, the absence of publicly available security policies, incident response contacts, and vulnerability disclosure mechanisms suggests room for improvement in transparency and readiness. Compliance with GDPR is indicated through cookie consent and privacy policy. The extensive use of third-party scripts necessitates ongoing security audits to mitigate risks. Overall, the security maturity is high but could benefit from enhanced communication of security governance.

Recommendations

  1. Publish a dedicated security policy and incident response contact information to improve transparency and trust.
  2. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Enhance contact information availability, including verified company emails and phone numbers for support and security inquiries.
  4. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Provide clear data retention policies and enhance user privacy transparency to align with evolving regulations.

Technical notes

Notes

NBC's website is built on a modern React framework with asynchronous ad loading via Google Publisher Tags and Adobe DTM for tag management. Performance monitoring is implemented using Boomerang. The site is optimized for mobile devices and accessibility with ARIA roles and responsive design. Hosting appears to leverage Akamai CDN for global content delivery. The technical infrastructure supports fast load times and a rich multimedia experience. However, the site relies heavily on third-party scripts which require vigilant security management. SEO is supported by proper meta tags, Open Graph, and JSON-LD structured data. Overall, the technical implementation is robust and aligns with industry best practices.
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.
