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 holds a strong market position as a central hub for gamers and developers, facilitating content sharing and social interaction. The platform's competitive advantage lies in its integration with the Steam store ecosystem, extensive user base, and robust content moderation and engagement tools. Revenue streams are primarily driven by digital game sales and marketplace transactions. The target customer segments include casual and hardcore gamers, game developers, and content creators. Strategic partnerships with developers and use of global CDN infrastructure support scalability and user experience. Growth indicators include continuous content updates, active community participation, and expansion of supported content types. The ecosystem is tightly integrated with Valve's other services, enhancing user retention and monetization opportunities.

Security posture

The website exhibits a high level of security maturity with enforced HTTPS, domain status protections against unauthorized changes, and use of a reputable CDN provider. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of explicit security headers such as Content-Security-Policy and HSTS represents an area for improvement. There is no visible security policy or incident response contact information on the community site, which could be enhanced to improve transparency and user trust. Compliance with GDPR is implied through linked privacy policies, but cookie consent mechanisms are not evident on this page. Overall, the security posture is strong but could benefit from additional header implementations and clearer security communication.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Add a dedicated security policy page and incident response contact information to improve transparency.
  4. Introduce explicit cookie consent mechanisms on community pages to reinforce privacy compliance.
  5. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.

Technical notes

Notes

The website uses a mature and well-structured technical infrastructure with JavaScript libraries such as Prototype.js, Scriptaculous, and jQuery, supported by Akamai CDN for content delivery. The platform is optimized for Windows users and demonstrates good mobile responsiveness and accessibility features. Meta tags and Open Graph data are properly configured for SEO and social media sharing. The site performance is fast, with efficient loading of assets and images. There is no detected CMS, indicating a custom-built platform tailored for Steam's specific needs. Technical risks are minimal, but modernization opportunities include updating legacy JavaScript frameworks and enhancing security headers.
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.
