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

The website open-slum.org operates as a niche monitoring dashboard focused on tracking the uptime and availability of various shadow library websites. It provides real-time status updates from a US-based server, serving an audience interested in the operational status of these controversial sites. The site does not host content itself nor endorses the monitored sites, positioning itself as an informational resource. Technically, the site employs modern web technologies including Vue.js and ES modules, hosted and registered via Cloudflare, ensuring a reliable and moderately performant infrastructure. However, the site lacks comprehensive privacy and security policies, with no cookie consent mechanisms or contact information provided, which limits its compliance posture. Security-wise, HTTPS is enforced and domain registration status is secure, but the absence of security headers and incident response details suggests room for improvement. Overall, the site presents moderate risk primarily due to the nature of the content it monitors and limited privacy compliance, but it maintains a functional and professional user experience.

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 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 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

Open-slum.org targets a specialized segment interested in shadow libraries, which are known for hosting unauthorized copyrighted materials. Its business model is informational, providing uptime monitoring rather than direct content or services. The site’s market position is niche with limited direct competition. Revenue streams or monetization are not evident. The partnership ecosystem includes links to multiple shadow library domains, but no formal partnerships or subsidiaries are indicated. Growth indicators are limited due to the site's recent creation in 2024 and its focused scope. Strategic observations suggest the site could enhance credibility by adding contact and compliance information and expanding transparency.

Security posture

The security maturity of open-slum.org is basic. The site benefits from HTTPS and Cloudflare’s infrastructure, which provides baseline protection. However, the lack of DNSSEC, security headers, and published security policies or incident response contacts indicates gaps in security best practices. No vulnerabilities or exposed sensitive data were detected in the analysis. Compliance with GDPR or other privacy regulations is minimal, with only a basic DMCA compliance notice present. Incident response readiness is not demonstrated. The site should prioritize implementing security headers, DNSSEC, and clear security policies to improve its posture.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement and publish a comprehensive privacy policy and cookie consent mechanism to improve privacy compliance.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  4. Publish incident response and security contact information to improve transparency and readiness.
  5. Consider adding analytics with privacy-respecting configurations to better understand user engagement while maintaining compliance.

Technical notes

Notes

The website uses a modern JavaScript framework (Vue.js) with ES modules, indicating a contemporary front-end architecture. Hosting and DNS are managed by Cloudflare, providing robust infrastructure and CDN capabilities. The site is mobile optimized and has a good design quality with clear navigation. However, the absence of security headers and DNSSEC suggests technical debt in security hardening. Performance is moderate, likely due to dynamic content and monitoring features. There are no detected forms or data collection points, reducing attack surface but also limiting user interaction. Opportunities exist to improve SEO and accessibility features for broader reach and compliance.
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.
