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. 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

  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
    • 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

Valve Corporation's Steam platform dominates the digital game distribution market with a vast catalog of games, community engagement tools, and hardware offerings. Its business model centers on digital sales, community-driven content, and developer partnerships. Revenue streams include game sales, in-game transactions, hardware sales, and subscription services. The platform serves a global audience of gamers and developers, supported by a mature partnership ecosystem including game publishers and hardware manufacturers. Growth indicators include continuous platform updates, new game releases, and hardware innovations like the Steam Deck. Strategic observations highlight Steam's strong brand equity, extensive user base, and integration of social and community features that enhance user retention and engagement.

Security posture

Steam exhibits a mature security posture with mandatory HTTPS, secure authentication mechanisms, and use of CDNs to mitigate DDoS and improve resilience. While explicit security headers such as Content-Security-Policy and X-Frame-Options are not directly observable in the provided HTML, it is likely they are implemented at the server or CDN level. No vulnerabilities or exposed sensitive data were detected in the content. Compliance with GDPR is indicated by a comprehensive privacy policy, though the absence of a cookie consent banner suggests room for improvement. Incident response and vulnerability disclosure mechanisms are not publicly evident, which could be enhanced to improve transparency and trust. Overall, Steam maintains a secure environment appropriate for its scale and user base.

Recommendations

  1. Implement and visibly display a cookie consent banner to enhance GDPR compliance and user transparency.
  2. Explicitly publish security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen client-side security.
  3. Establish and publicize a dedicated vulnerability disclosure policy and security.txt file to encourage responsible reporting and improve security posture.
  4. Provide clear contact information for security incidents, including dedicated security and abuse email addresses.
  5. Regularly audit third-party scripts and dependencies to mitigate risks from vulnerable libraries and ensure ongoing security.

Technical notes

Notes

The Steam website is built on a mature and scalable technical infrastructure utilizing Akamai CDN for global content delivery, ensuring fast load times and high availability. The front-end employs jQuery 1.8.3 and custom JavaScript for dynamic content and user interaction, alongside responsive CSS for mobile optimization. The platform supports multiple operating systems and VR hardware, reflecting a broad technical compatibility. Performance is optimized through efficient asset loading and video streaming capabilities. However, some legacy libraries like jQuery 1.8.3 may warrant updating to reduce security risks. The absence of explicit CMS indicators suggests a custom-built platform tailored to Steam's unique requirements. Overall, the technical implementation supports a robust, user-friendly, and performant digital storefront.
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.
