Security score

Risk levelLow

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

HBO is a leading premium media and entertainment company specializing in original series, movies, documentaries, and exclusive video content. The website serves as the official platform for streaming and information dissemination, targeting a broad general audience with a subscription-based business model. HBO maintains a strong market position as a top-tier content provider under the Warner Bros. Discovery umbrella. Technically, the site leverages modern web technologies including React and Next.js, ensuring fast performance, mobile optimization, and good accessibility. Security posture is robust with HTTPS, security headers, and cookie consent mechanisms, although explicit security policies and incident response contacts are not publicly disclosed. Overall, the site demonstrates high professionalism, trustworthiness, and compliance with privacy regulations such as GDPR. The absence of WHOIS data is consistent with privacy protection practices common among large enterprises and does not detract from the site's legitimacy.

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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

HBO operates in the media sector with a focus on premium content streaming. Its competitive advantage lies in exclusive original programming and a strong brand legacy. Revenue streams primarily come from subscriptions and licensing. The target customer segment is broad, encompassing general audiences seeking high-quality entertainment. The company benefits from a robust partnership ecosystem, including authentication services via auth.max.com. Growth indicators include continuous content updates and expansions in streaming offerings. Strategic observations highlight HBO's emphasis on digital transformation and user experience to maintain market leadership.

Security posture

HBO exhibits a mature security posture with enforced HTTPS, comprehensive security headers, and a cookie consent framework aligned with privacy laws. No exposed sensitive data or vulnerable libraries were detected in the analysis. However, the lack of publicly available security policies, incident response contacts, and vulnerability disclosure mechanisms suggests room for improvement in transparency and readiness communication. Compliance with GDPR is evident through consent management. The security culture appears strong but could benefit from enhanced public-facing documentation to bolster trust and incident handling clarity.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact information, such as a security@ or abuse@ email address.
  3. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Enhance transparency around data retention and privacy compliance details.
  5. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on a modern technology stack featuring React and Next.js, enabling server-side rendering and optimized performance. The use of Webpack and modular JavaScript supports maintainability and scalability. The site is mobile-optimized with responsive design and accessibility considerations. SEO is well addressed through meta tags and structured data (JSON-LD). Hosting details are not explicitly identified but the presence of CDN and cookie consent scripts indicates a professional infrastructure. Performance is fast with lazy loading of images and deferred scripts. Technical risks are minimal, with no visible deprecated or vulnerable components.
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.
