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

The website git-send-email.io is an educational resource focused on teaching developers how to use git's email collaboration tools effectively. It provides detailed step-by-step tutorials covering installation, configuration for various email providers, sending patches, handling feedback, and best practices. The site targets developers and contributors involved in open source projects who want to leverage email workflows for git contributions. The business behind the domain is small and technology-focused, with a clear niche in developer education. Technically, the site is well-structured with clean HTML and CSS, hosted likely on sourcehut infrastructure as indicated by name servers and footer references. The site is performant, mobile-optimized, and accessible, though it lacks advanced SEO features and does not use a CMS. No analytics or tracking scripts are present, enhancing user privacy. From a security perspective, the site uses HTTPS (implied by URL), but no explicit security headers were detected in the provided data. The domain lacks DNSSEC and privacy policies, indicating room for improvement in compliance and security best practices. No forms or sensitive data collection reduces risk exposure. WHOIS data shows a legitimate registration with a reputable registrar and appropriate domain age. Overall, the site is a trustworthy, high-quality educational platform with minor gaps in privacy and security policy disclosures. Strategic improvements in security headers, privacy compliance, and vulnerability disclosure mechanisms would enhance its security posture and user trust.

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

7 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

  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 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 X-Frame-Options header

      Prevents clickjacking attacks

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

  3. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

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

Business profile

git-send-email.io operates as a niche educational platform within the technology sector, focusing on git email workflows. Its market positioning is that of a specialized tutorial resource catering to developers contributing to open source projects. The business model appears community-driven and non-commercial, with no evident monetization or advertising. The target audience includes developers, open source contributors, and technical users seeking to improve their git email collaboration skills. The site leverages partnerships with sourcehut and references official git resources, indicating a collaborative ecosystem. Growth indicators are limited but the detailed, high-quality content suggests a stable presence within its niche.

Security posture

The website demonstrates a moderate security maturity level. HTTPS is used, but no security headers such as Content-Security-Policy or Strict-Transport-Security were detected, which are recommended to mitigate common web vulnerabilities. The absence of privacy and cookie policies indicates compliance gaps with GDPR and other privacy regulations. No vulnerability disclosure or incident response information is provided, limiting transparency. The site does not collect user data or use tracking, reducing attack surface. WHOIS data is consistent and legitimate, with no suspicious patterns. Overall, the security posture is adequate for an informational site but could be improved with enhanced headers, policies, and disclosure mechanisms.

Recommendations

  1. Implement standard security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to improve protection against common web attacks.
  2. Publish comprehensive privacy and cookie policies to enhance GDPR compliance and user trust.
  3. Enable DNSSEC for the domain to improve DNS security and integrity.
  4. Add a security.txt file or vulnerability disclosure policy to facilitate responsible reporting of security issues.
  5. Consider adding minimal analytics with privacy-respecting configurations to monitor site usage and improve user experience.

Technical notes

Notes

The website is built with clean, semantic HTML5 and CSS3, without reliance on heavy JavaScript frameworks or CMS platforms, which contributes to fast loading times and good accessibility. The hosting appears to be on sourcehut infrastructure, known for minimalistic and privacy-focused hosting. The site is mobile responsive and well-structured with clear navigation steps. There is no evidence of technical debt or outdated technologies. However, the lack of security headers and DNSSEC indicates some technical security gaps. SEO optimization is basic, with meta viewport and charset tags present but no Open Graph or structured data detected. Overall, the technical implementation is solid for an educational site but could benefit from modern security and SEO enhancements.
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.
