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

The website go.dev is the official site for the Go programming language, an open source project supported and maintained by Google LLC. It serves as a comprehensive resource hub for developers, offering documentation, learning materials, downloads, and community engagement. The site targets software developers and engineering teams seeking to build secure, scalable systems using Go. The business model revolves around providing an open source programming language ecosystem backed by a major technology company, positioning Go as a leading language in cloud and network services, web development, and DevOps. Technically, the site is well-implemented with modern web technologies including HTML5, CSS3, JavaScript, and Google’s own analytics and tag management tools. It is hosted on Google Cloud Platform, ensuring fast performance and excellent mobile optimization. The site demonstrates good SEO and accessibility practices, with clear navigation and professional design. No CMS is detected, indicating a custom-built platform tailored for the Go project. From a security perspective, the website enforces HTTPS with strong SSL configuration and includes standard security headers. It uses Google Analytics and Tag Manager scripts loaded asynchronously, and a cookie consent banner is present to comply with privacy regulations. However, there is no explicit security policy or vulnerability disclosure page, nor contact information for incident response, which are areas for improvement. No vulnerabilities or exposed sensitive data were detected. Overall, go.dev is a high-quality, trustworthy, and professional website that effectively supports the Go programming language community. It reflects the credibility of Google LLC and provides valuable resources for developers. Strategic recommendations include publishing a dedicated security policy, adding vulnerability disclosure information, and providing clear security incident contacts to enhance trust and compliance.

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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  2. 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  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

Go.dev is positioned as a leading open source programming language platform backed by Google LLC, targeting developers and technology companies. Its competitive advantages include strong corporate backing, a large ecosystem, and comprehensive learning and documentation resources. The business model is centered on open source software development and community engagement rather than direct monetization. The site features case studies from major global companies, indicating wide adoption and industry trust. Partnerships with cloud providers and integration with popular tools further strengthen its market position. Growth indicators include active community involvement, extensive educational content, and continuous updates. The strategic ecosystem includes Google Cloud, AWS, Azure, and various open source projects, reflecting a broad and collaborative approach.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, excellent SSL configuration, and multiple security headers. Use of Google-managed analytics and tag management reduces risk from third-party scripts. The presence of a cookie consent banner indicates privacy awareness and GDPR compliance. However, the absence of a published security policy, vulnerability disclosure program, and incident response contact information represents a compliance gap and potential risk in transparency and responsiveness. No exposed sensitive data or vulnerabilities were found in the content. Overall, the security maturity is good but could be improved by formalizing security governance documentation and communication channels.

Recommendations

  1. Publish a dedicated security policy page detailing security practices and commitments.
  2. Implement and publicize a vulnerability disclosure program including a security.txt file.
  3. Provide explicit contact information for security incidents such as security@ or abuse@ email addresses.
  4. Enhance accessibility features to meet or exceed WCAG standards.
  5. Regularly audit and update third-party scripts to mitigate supply chain risks.

Technical notes

Notes

The website is built on a custom platform using modern web standards (HTML5, CSS3, JavaScript) and leverages Google Tag Manager and Google Analytics for tracking. Hosting on Google Cloud Platform ensures high availability and fast performance. The site is mobile optimized with responsive design and includes accessibility features such as skip navigation links and ARIA labels. SEO is well addressed with meta tags, Open Graph, and Twitter card metadata. No CMS or frameworks like React or Angular were detected, indicating a lightweight and performant implementation. The technical infrastructure is robust with minimal technical debt and good modernization practices, supporting the business goals effectively.
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.
