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

6 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. GDPR outside view

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

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, Twitter, LinkedIn

      What to do: Document all third-party data sharing in your privacy policy

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

Blizzard Entertainment operates in the technology and e-commerce sectors, focusing on digital distribution of gaming products. The business model centers on direct sales to consumers via its Battle.net platform, leveraging strong brand recognition and a loyal customer base. The company benefits from its parent, Activision Blizzard, and maintains a global presence. The website's content and structure reflect a well-established market position with clear product offerings and customer engagement strategies. Partnerships with major content delivery networks and analytics providers support operational efficiency and marketing effectiveness.

Security posture

The website exhibits a high level of security maturity, with enforced HTTPS, multiple security headers, and no visible vulnerabilities or exposed sensitive data. Privacy compliance is evident through detailed privacy and cookie policies and active consent management. However, there is no publicly visible dedicated security policy or incident response contact information, which could be improved to enhance transparency and readiness. No vulnerability disclosure or security.txt files were detected, suggesting an opportunity to formalize security communication channels. Overall, the security posture is strong but could benefit from enhanced incident response visibility.

Recommendations

  1. Implement and publicly link a dedicated security policy and incident response page.
  2. Publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  3. Regularly audit and update third-party libraries to mitigate potential vulnerabilities.
  4. Enhance contact information availability for security and privacy inquiries.
  5. Maintain and monitor cookie consent mechanisms to ensure ongoing GDPR compliance.

Technical notes

Notes

The website uses a modern tech stack including JavaScript frameworks (likely Angular), Google Tag Manager for analytics, and OneTrust for cookie consent management. Content is delivered via Akamai CDN, ensuring fast load times and global availability. The site is mobile-optimized with responsive design and accessibility considerations. SEO practices are well implemented with proper meta tags and structured data. No CMS was explicitly detected, suggesting a custom or proprietary platform. The technical infrastructure supports a high-quality user experience with minimal technical debt visible from the front-end analysis.
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.
