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

Valve Corporation operates a professional and well-branded website focused on game development, the Steam digital distribution platform, and hardware innovation. The site targets gamers, developers, hardware engineers, and business partners, positioning itself as a leading technology company in the gaming industry. The business model centers on product development and digital platform services, supported by a large company size and consistent branding. Technically, the website employs modern web technologies including jQuery, Google reCAPTCHA, HTML5 video, and is hosted on Akamai CDN, ensuring fast performance and good mobile optimization. SEO and accessibility are adequately addressed, though accessibility is basic. Security posture is strong with HTTPS enforced and use of CAPTCHA, but lacks explicit security headers and a cookie consent mechanism. The security evaluation reveals no critical vulnerabilities or exposed sensitive data. However, the absence of WHOIS data for the domain is unusual and reduces trust slightly, though the website content and external links strongly indicate legitimacy. Privacy policies are comprehensive and GDPR compliant, hosted on related Steam domains. No incident response or vulnerability disclosure information is publicly available. Overall, the website is professional, secure, and trustworthy with minor areas for improvement in security headers and privacy consent. The domain WHOIS inconsistency warrants monitoring but does not currently undermine the site's credibility.

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 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
    • 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 Cookie Policy found

      GDPR requires clear information about cookie usage

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

    • 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

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 holds a strong market position as a pioneer in gaming software and digital distribution through Steam. Its competitive advantage lies in its integrated ecosystem of game development, digital storefront, and hardware innovation. The business model leverages product sales, platform fees, and hardware sales. Target customers include gamers, developers, and business partners. Growth is supported by continuous hiring across diverse technical and creative roles. The partnership ecosystem includes Steam partners and developers. Strategic observations highlight a flat organizational structure and emphasis on collaboration, which may foster innovation and agility.

Security posture

Valve's security maturity is solid with HTTPS enforced and use of Google reCAPTCHA to protect forms. The lack of explicit security headers such as Content Security Policy and HSTS is a gap that could be exploited in certain attack scenarios. No vulnerabilities or exposed sensitive data were detected. Compliance with GDPR is indicated by linked privacy policies, but no cookie consent mechanism was found, which is a compliance risk. Incident response readiness is unclear due to absence of public contact channels for security issues. Overall, the security culture appears mature but could benefit from enhanced transparency and technical controls.

Recommendations

  1. Implement and enforce security headers including Content Security Policy, HSTS, and X-Frame-Options to strengthen defense-in-depth.
  2. Add a cookie consent banner/mechanism to comply fully with GDPR and other privacy regulations.
  3. Publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  4. Provide clear incident response contact information on the website to improve transparency and trust.
  5. Investigate and resolve the missing WHOIS data to enhance domain registration transparency and trustworthiness.

Technical notes

Notes

The website uses a stable and proven technology stack with jQuery 1.8.3 and Google reCAPTCHA for security. Multimedia content is delivered via HTML5 video with fallback formats, ensuring compatibility. Hosting on Akamai CDN provides fast global content delivery. The site is mobile optimized with responsive design and uses semantic meta tags for SEO. However, the use of an older jQuery version may pose security risks and modernization opportunities exist. Accessibility is basic and could be improved with ARIA roles and better keyboard navigation support. No CMS detected, indicating a custom or static site architecture.
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.
