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 Policy found

      GDPR requires clear information about cookie usage

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

  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

GitHub holds a dominant position in the developer tools market, serving a broad audience from individual developers to large enterprises. Its SaaS business model focuses on subscription services for private repositories, enterprise solutions, and AI-powered developer tools. Revenue streams include paid plans, enterprise licenses, and marketplace integrations. The company benefits from Microsoft's backing, enabling extensive resources and global reach. Partnerships with technology providers and event platforms like GitHub Universe strengthen its ecosystem. Growth indicators include continuous feature expansion (e.g., GitHub Copilot, Spark) and strong community engagement. The website content and structure reflect a mature, professional operation aligned with industry best practices.

Security posture

GitHub demonstrates a high level of security maturity with enforced HTTPS, comprehensive security headers, and adherence to recognized frameworks such as ISO 27001 and NIST. The presence of a vulnerability disclosure policy and dedicated security contacts indicates readiness for incident response. No exposed sensitive data or vulnerable libraries were detected. The site uses secure forms with CSRF protection and employs reputable third-party libraries. Minor gaps include the absence of DNSSEC, which is recommended to prevent DNS spoofing. Overall, GitHub maintains a strong security culture and infrastructure suitable for enterprise-grade operations.

Recommendations

  1. Enable DNSSEC on the github.com domain to enhance DNS security and prevent spoofing attacks.
  2. Implement regular automated audits of third-party libraries and dependencies to identify and remediate vulnerabilities promptly.
  3. Increase transparency by publishing detailed data retention policies and privacy impact assessments.
  4. Enhance user trust by providing more visible security certifications and compliance badges on the website.
  5. Develop a long-term security strategy focusing on emerging threats such as supply chain attacks and AI-driven vulnerabilities.

Technical notes

Notes

The website is built using modern front-end technologies including React and Turbo, ensuring a responsive and dynamic user experience. Contentful CMS is used for content management, enabling efficient updates and scalability. Hosting is provided by AWS with multiple DNS providers for redundancy. The site employs SVG icons and optimized fonts for performance. Accessibility features such as keyboard shortcuts and ARIA labels are implemented, supporting inclusive design. SEO is addressed with proper meta tags and Open Graph data. Performance is optimized with preloading and deferred script loading. Technical risks are minimal, with opportunities for improvement in DNS security and continuous modernization.
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.
