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

4 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 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. 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

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

Dolby is positioned as a premium technology provider in the audio-visual entertainment industry, leveraging licensing and partnerships to monetize its innovations. Its competitive advantage lies in proprietary technologies like Dolby Atmos and Dolby Vision, which are widely adopted across consumer devices and content platforms. The company targets a broad audience including consumers, content creators, device manufacturers, and professionals. Revenue streams likely include licensing fees, professional services, and consumer product ecosystems. The presence of multiple regional sites and language versions indicates a global market reach. The company maintains a strong partnership ecosystem with device makers and streaming services. Growth indicators include continuous technology innovation and expansion into new sectors like automotive audio. Strategic observations highlight Dolby’s focus on immersive experiences and maintaining brand leadership through consistent messaging and high-quality digital presence.

Security posture

Dolby’s current security maturity is moderate to good. The website employs secure cookies and a valid SSL certificate but lacks support for modern TLS protocols and HSTS, which are critical for protecting data in transit. The absence of security.txt and explicit incident response contacts suggests room for improvement in transparency and readiness. The cookie consent mechanism and comprehensive privacy and cookie policies demonstrate compliance with GDPR and privacy best practices. No known vulnerabilities or weak cipher suites were detected. The use of multiple third-party analytics and marketing tools introduces potential privacy risks, but these are managed with consent mechanisms. Overall, the security culture appears mature but could benefit from enhanced protocol support, security headers, and clearer incident response communication.

Recommendations

  1. Enable TLS 1.2 or higher protocols and disable legacy SSL/TLS versions to improve encryption security.
  2. Implement HTTP Strict Transport Security (HSTS) with includeSubDomains and preload directives to prevent protocol downgrade attacks.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  4. Publish a security.txt file and provide explicit incident response contact information to improve vulnerability disclosure and response.
  5. Regularly review third-party scripts and tracking tools to ensure privacy compliance and minimize data exposure.
Technical notes

Notes

The website infrastructure is modern and robust, utilizing Cloudflare for hosting and CDN services, and EPiServer CMS for content management. The tech stack includes Vue.js components, jQuery, and multiple marketing and analytics integrations such as Braze, Google Tag Manager, Hotjar, and Optimizely. Performance is fast with good mobile optimization and accessibility. The site uses asynchronous and deferred loading for scripts and fonts, enhancing load times. However, the SSL configuration lacks support for modern TLS protocols, which is a technical debt and security risk. DNS configuration does not include DNSSEC or CAA records, which could improve domain security. Overall, the technical environment supports a high-quality user experience but requires updates to security protocols and headers to reduce risks.
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.
