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

Steam's business model centers on digital sales and distribution of video games and software, supplemented by community engagement and hardware sales. The platform's extensive catalog and global reach position it as a market leader. Revenue streams include game sales, DLC, hardware, and digital gift cards. The target customer segments include casual and hardcore gamers, indie developers, and publishers. Partnerships with developers and publishers are facilitated through dedicated partner sites. The platform's growth is supported by continuous content updates, curated recommendations, and community features. Strategic observations highlight Valve's focus on user experience, platform stability, and ecosystem expansion through hardware and software integration.

Security posture

The Steam Store website exhibits a mature security posture with HTTPS enforced site-wide and implementation of key security headers such as Strict-Transport-Security, X-Frame-Options, and Content-Security-Policy. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. However, the absence of a public vulnerability disclosure policy or security.txt file and lack of explicit incident response contact information represent areas for enhancement. Cookie consent mechanisms are not evident, which may impact compliance with privacy regulations. Overall, the security measures align with industry best practices, supporting a secure user experience.

Recommendations

  1. Implement a clear and user-friendly cookie consent banner to comply with privacy regulations.
  2. Publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  3. Provide explicit incident response contact information, such as a dedicated security or abuse email address.
  4. Enhance transparency around data retention and privacy practices to strengthen user trust.
  5. Regularly review and update third-party libraries and dependencies to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on a robust technical infrastructure utilizing jQuery 1.8.3 and custom JavaScript, served via Akamai CDN for optimized performance and global reach. The site employs responsive design techniques ensuring excellent mobile optimization and accessibility. SEO is well addressed through comprehensive meta tags and Open Graph data. The absence of a CMS suggests a custom-built platform tailored for scalability and performance. The site demonstrates fast loading times and modern web standards adherence. Opportunities exist to modernize JavaScript libraries to newer versions and to implement enhanced privacy and security features to align with evolving compliance requirements.
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.
