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

Steam Community, operated by Valve Corporation, is a leading global platform for gamers and developers to share content, engage in discussions, and access official game hubs. It serves as a comprehensive community ecosystem integrated with the Steam digital distribution platform, offering user-generated content such as screenshots, videos, guides, and workshop items. The platform targets a broad audience of gamers worldwide and maintains a strong market position as a trusted and established gaming community hub. Technically, the website leverages modern web technologies including Prototype.js, Scriptaculous, jQuery, and extensive use of Akamai CDN for performance and scalability. The site is mobile-optimized and accessible, with a professional and consistent design aligned with the Steam brand. Security-wise, the site enforces HTTPS, employs domain locking mechanisms, and avoids exposing sensitive data. However, it lacks visible cookie consent mechanisms and explicit security or incident response policies on the community site. Overall, the site is safe for general audiences with no adult content detected, and the domain registration details confirm high legitimacy and trustworthiness.

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

  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

  3. 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 Community platform complements its digital storefront by fostering user engagement and content sharing, which enhances user retention and platform stickiness. The business model revolves around digital distribution, community engagement, and marketplace transactions. The platform's extensive user base and integration with Steam's store ecosystem provide competitive advantages. Revenue streams include game sales, marketplace transactions, and potentially advertising or promotional partnerships. The target customers are gamers, content creators, and developers globally. The partnership ecosystem includes related domains such as the Steam Store, support, and developer portals. The platform demonstrates growth through active user-generated content and community activities, reinforcing Valve's market leadership in digital game distribution and community services.

Security posture

The Steam Community website exhibits a mature security posture with enforced HTTPS, domain registration protections, and no visible exposure of sensitive information. The use of reputable CDNs and modern JavaScript libraries supports secure and performant delivery. However, the absence of explicit cookie consent banners and visible security policies or incident response contacts represents a compliance gap, especially under GDPR and similar regulations. No vulnerability disclosure or security.txt files were found, which could limit external security reporting. Overall, the platform is secure but could improve transparency and compliance by publishing security policies and implementing cookie consent mechanisms.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement a visible cookie consent mechanism to comply with GDPR and other privacy regulations.
  3. Publish a clear security policy and incident response contact information on the community site.
  4. Provide a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Regularly review and update third-party libraries to mitigate potential vulnerabilities.

Technical notes

Notes

The website uses a custom CMS with a tech stack including Prototype.js, Scriptaculous, and jQuery 1.11.1, which are somewhat dated but still functional. The extensive use of Akamai CDN ensures fast content delivery globally. The site is mobile-optimized and accessible, with good SEO practices including meta tags and Open Graph data. Performance is fast due to CDN usage and optimized assets. There is an opportunity to modernize JavaScript libraries and frameworks to improve maintainability and security. The site architecture supports dynamic content loading and user interaction effectively, but cookie consent and privacy compliance features should be enhanced.
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.
