Risk levelMedium

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

The website lina.sh is a personal site of Lina, a young developer from Germany, focusing on internet transparency and community engagement. The site highlights Lina's projects, including CUII-Liste, which exposes wrongful ISP domain blocking in Germany. The business model is personal branding supported by donations, targeting developers and privacy-conscious users. The site is technically simple, using no JavaScript, relying on HTML and CSS, and hosted with Cloudflare DNS and Porkbun LLC as registrar. It demonstrates good performance and mobile optimization but lacks advanced SEO and accessibility features. Security posture is moderate with domain locks and published PGP keys but lacks DNSSEC and security headers. Privacy compliance is weak due to missing privacy and cookie policies. Overall, the site is trustworthy, safe, and professional but could improve compliance and security practices.

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 X-Frame-Options header

      Prevents clickjacking attacks

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

  2. 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

    • 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

Lina.sh operates as a small-scale personal technology site with a niche focus on internet censorship transparency and developer community engagement. The site leverages partnerships with payment processors like PayPal and Ko-fi for donations and uses popular community platforms such as Discord, Matrix, and Mastodon to maintain user interaction. The business model is donation-based with no advertising or tracking, emphasizing privacy and openness. The domain registration and hosting choices reflect a preference for privacy and control. Growth indicators include media coverage and active social presence. The partnership ecosystem is limited but relevant to the site's mission.

Security posture

The website exhibits a moderate security maturity level. It uses HTTPS (implied by Cloudflare DNS and modern web standards), domain status locks to prevent unauthorized transfers or deletions, and publishes a PGP public key for secure communication. However, it lacks DNSSEC, security headers, and formal security policies such as vulnerability disclosure or incident response contacts. No exposed sensitive data or vulnerabilities were detected in the content. Compliance gaps exist in privacy and cookie policies. Incident response readiness is not evident. Overall, the security culture appears privacy-focused but could benefit from formalized policies and enhanced technical controls.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement standard security headers (CSP, HSTS, X-Frame-Options) to protect against common web attacks.
  3. Publish a privacy policy and cookie policy to improve GDPR compliance and user trust.
  4. Create a vulnerability disclosure or security.txt page to facilitate responsible reporting of security issues.
  5. Regularly review and update security posture including SSL/TLS configuration and monitoring for vulnerabilities.

Technical notes

Notes

The website is built with clean HTML5 and CSS3 without JavaScript, which is unusual but intentional for privacy and performance. It uses Cloudflare DNS and Porkbun LLC as registrar, with domain locks enabled. The site is fast and mobile-optimized with good accessibility and basic SEO. No CMS or frameworks detected, indicating a static or custom-built site. The absence of JavaScript reduces attack surface but limits interactivity. The site uses iframes for dynamic content like Discord status and email rendering. Technical risks include lack of DNSSEC and missing security headers. Overall, the infrastructure is simple, performant, and privacy-conscious but could be modernized with enhanced security 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.
