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

Vulcain.rocks is a technology-focused website promoting the Vulcain protocol, which leverages HTTP/2 features such as preload hints, Early Hints, and Server Push to create fast, client-driven REST APIs. The site is supported by Les-Tilleuls.coop, which offers professional services including web development, training, and consulting around this technology. The website targets developers and API providers seeking to optimize API performance and usability. Technically, the site is built with modern frameworks including Next.js and Material-UI, and integrates Google Analytics and Tag Manager for user tracking. The design is professional, mobile-optimized, and accessible, providing a good user experience. Security-wise, the site uses HTTPS and does not expose sensitive data, but lacks explicit security headers and published security policies. Privacy compliance is limited due to missing privacy and cookie policies. Overall, the domain appears legitimate though WHOIS data is privacy protected and incomplete.

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

8 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"

    • 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';…

  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

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

The Vulcain project occupies a niche in the API optimization and hypermedia space, offering an open source protocol and gateway to enhance existing APIs. Its business model includes open source software combined with professional services and training provided by Les-Tilleuls.coop. The project benefits from partnerships within the API Platform ecosystem and related real-time technologies like Mercure.rocks. The target market is developers and organizations seeking advanced API performance solutions. The presence of community support channels and training offerings indicates a focus on ecosystem growth and developer engagement. The website content and branding are consistent and professional, supporting a credible market position in the technology sector.

Security posture

The website demonstrates a moderate to good security posture with mandatory HTTPS enabled and no visible sensitive data exposure. However, it lacks several best practices such as explicit security headers (CSP, HSTS, X-Frame-Options), published privacy and cookie policies, and a vulnerability disclosure or incident response contact. The use of Google Analytics and Tag Manager introduces moderate user tracking, but no advanced privacy compliance measures are evident. The absence of a security.txt or similar document limits transparency for security researchers. Overall, the security maturity is adequate for a small technology project but could be improved to meet higher compliance and trust standards.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy to improve GDPR compliance and user trust.
  2. Implement and configure security headers such as Content Security Policy, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  3. Create and publish a vulnerability disclosure policy or security.txt file to facilitate responsible security reporting.
  4. Add incident response contact information, including dedicated security or abuse email addresses.
  5. Review and minimize user tracking practices to align with privacy best practices and improve transparency.

Technical notes

Notes

The website is built on a modern React-based stack using Next.js for server-side rendering and Material-UI for styling, ensuring a responsive and accessible design. Performance is optimized with preloading of fonts and images, and the site is mobile-friendly. Analytics are implemented via Google Analytics and Tag Manager, providing moderate user tracking capabilities. No CMS or hosting provider details are explicitly detected. The site does not expose any vulnerable libraries or sensitive data in the HTML. However, the absence of explicit security headers and privacy policies indicates areas for technical improvement. Overall, the technical infrastructure is solid and well-suited for the target audience.
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.
