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

Alpine Linux is a small, security-oriented Linux distribution project founded in 2006, focusing on providing a lightweight and secure operating system based on musl libc and busybox. The website serves as a hub for news, downloads, community engagement, and development resources, positioning Alpine Linux as a niche but respected player in the open source Linux ecosystem. The project maintains active development with frequent releases and community contributions, supported by a consistent and professional web presence. Technically, the website is built with clean HTML5 and CSS using Pure.css and FontAwesome for styling and icons. It is hosted on Linode, a reputable cloud provider, and uses GitLab for source control and issue tracking. The site is mobile responsive and well-structured, though it lacks advanced CMS or analytics integrations. Performance is likely fast given the minimalistic design and static content delivery. From a security perspective, the domain registration is solid with a long history and clientTransferProhibited status, but the website lacks DNSSEC and security headers, which are recommended to enhance protection. No explicit privacy or cookie policies beyond a basic privacy policy page were found, and no contact or incident response information is provided, which could be improved to increase trust and compliance. No WAF or blocking mechanisms were detected, and no vulnerabilities or sensitive data exposures were observed. Overall, Alpine Linux's website is trustworthy and professional but could benefit from enhanced security practices and privacy compliance measures to align with modern standards. Strategic improvements in security headers, DNSSEC, and transparency around data protection would strengthen its 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

3 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 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

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

Alpine Linux operates as an open source project delivering a specialized Linux distribution emphasizing security and minimalism. Its market positioning is niche, targeting developers, security professionals, and users requiring a lightweight OS. The business model is community-driven with sponsorship and donation support. The project demonstrates steady growth with regular releases and active development visible through GitLab commits. The ecosystem includes documentation, package repositories, and community forums, fostering collaboration. Alpine Linux's competitive advantage lies in its security focus and small footprint, differentiating it from mainstream distributions. Partnerships or subsidiaries are not evident, and the project relies on volunteer contributions and sponsorships for sustainability.

Security posture

The security maturity of Alpine Linux's website is moderate. The domain registration is trustworthy with a reputable registrar and long tenure. However, the absence of DNSSEC and security headers such as Content-Security-Policy and Strict-Transport-Security reduces the overall security posture. No incident response or vulnerability disclosure information is provided, limiting transparency and readiness communication. The site uses HTTPS (implied by modern standards though not explicitly confirmed in HTML), but no cookie consent or privacy compliance mechanisms are evident. No tracking or analytics scripts reduce privacy risks but also limit user behavior insights. Overall, the security posture is adequate for an informational site but could be improved to meet higher compliance and protection standards.

Recommendations

  1. Enable DNSSEC on the domain to prevent DNS spoofing and improve domain security.
  2. Implement standard security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Add a cookie policy and consent mechanism if cookies or tracking technologies are used.
  4. Publish clear contact information and an incident response policy or security.txt file to improve transparency and trust.
  5. Regularly review and update privacy policies to ensure GDPR and other privacy regulation compliance.

Technical notes

Notes

The website uses a minimalistic and clean technical stack with static HTML and CSS frameworks (Pure.css, FontAwesome). It is hosted on Linode, indicating reliable infrastructure. The site is mobile responsive and well-structured for usability and SEO. No CMS or dynamic backend detected, reducing attack surface but limiting content management flexibility. No analytics or tracking scripts found, enhancing privacy but limiting marketing insights. The absence of security headers and DNSSEC represents technical debt and potential risk. Overall, the infrastructure is modern and performant but could benefit from additional security hardening and privacy features.
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.
