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

WebSubHub is a small, niche technology service offering a fully compliant WebSub hub endpoint to distribute live content updates from various publishers. The service is open source and targets developers and publishers who require real-time content distribution using the WebSub protocol. The website is professionally designed with clear navigation and relevant technical content, reflecting a focused and consistent brand presence. The domain is relatively new, registered in 2022, and aligns well with the business's stated purpose. Technically, the website leverages modern technologies including the Elixir Phoenix framework, Cloudflare DNS, Chart.js for visualization, and Plausible Analytics for privacy-focused user tracking. The site is moderately optimized for performance and mobile use, with basic accessibility and SEO features. However, some improvements could be made in security headers and DNSSEC implementation. From a security perspective, the site uses HTTPS and has domain registration protections in place, but lacks explicit security headers and published security or privacy policies. No vulnerabilities or sensitive data exposures were detected. The absence of privacy and cookie policies and contact information reduces compliance and trustworthiness scores. No WAF or blocking mechanisms were detected, and the content is safe for general audiences. Overall, WebSubHub presents a credible and functional technology service with room for improvement in privacy compliance and security best practices. Strategic enhancements in policy publication, security headers, and contact transparency would strengthen trust and compliance posture.

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. 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

WebSubHub operates in the technology sector, providing a specialized WebSub hub service that supports real-time content distribution. Its open source nature and GitHub presence suggest a community-driven approach. The business model appears to be service-oriented, offering a free hub endpoint to attract developers and publishers. The target market is niche but essential for applications relying on WebSub protocols. The company is small, founded in 2022, with no parent or subsidiary companies identified. Partnerships include links to GitHub and Axxim, indicating collaboration or publishing support. The lack of explicit revenue streams or monetization details suggests a focus on community and open source contribution rather than commercial sales. Growth potential depends on adoption within the developer community and integration with other WebSub services.

Security posture

The security posture of WebSubHub is moderate. The site enforces HTTPS and has domain registration protections such as clientDeleteProhibited and clientTransferProhibited statuses. However, DNSSEC is not enabled, and no security headers (e.g., CSP, HSTS) were detected in the provided data. There are no published security policies or incident response contacts, which limits transparency and readiness for security events. No vulnerabilities or exposed sensitive data were found, and the use of modern frameworks reduces risk. The absence of privacy and cookie policies indicates compliance gaps, particularly regarding GDPR. Overall, the site is secure for its purpose but would benefit from enhanced security controls and policy disclosures.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement and publish comprehensive privacy and cookie policies to enhance GDPR compliance.
  3. Add standard security headers such as Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options.
  4. Provide clear contact information including security or abuse contacts to improve incident response readiness.
  5. Consider publishing a vulnerability disclosure policy or security.txt file to encourage responsible reporting.

Technical notes

Notes

The website is built using the Elixir Phoenix framework, indicating a modern and scalable backend technology. Frontend assets include Chart.js for data visualization and Plausible Analytics for privacy-respecting user tracking. DNS is managed via Cloudflare, providing reliable DNS services though DNSSEC is not enabled. The site uses HTTPS exclusively, ensuring encrypted communications. Performance is moderate with deferred and async loading of scripts. Accessibility and SEO are basic but present. No CMS was detected, suggesting a custom or framework-based site. Hosting details beyond DNS are not explicit but likely cloud-based. Overall, the technical infrastructure is solid but could be enhanced with additional security headers and improved policy disclosures.
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.
