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

ZeroDisclo.com is a non-profit platform dedicated to facilitating coordinated vulnerability disclosure by providing a secure and confidential environment for security researchers and organizations. The platform addresses key barriers such as legal uncertainty, lack of proper disclosure channels, and communication inefficiencies by partnering with CERTs and leveraging the expertise of YesWeHack. The website presents a clear focus on security research community needs and coordinated disclosure processes. Technically, the website is built using modern JavaScript frameworks including Vue.js and Quasar, hosted via Gandi SAS. The site demonstrates moderate performance and good mobile optimization, though accessibility and SEO optimizations are basic. No major technical issues or vulnerabilities were detected in the provided content, and HTTPS is enforced with a stable domain registration. From a security perspective, the site benefits from HTTPS and domain transfer protections but lacks advanced security headers and explicit incident response contact details. Privacy compliance is partial, with a privacy policy present but no cookie consent mechanism detected. The absence of contact information and security policy details limits transparency. Overall, the security posture is solid but could be improved with additional controls and disclosures. The overall risk is moderate with no critical issues detected. Strategic improvements in privacy compliance, security headers, and contact transparency would enhance trust and security culture. The platform is well-positioned as a trusted facilitator in the vulnerability disclosure ecosystem.

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. 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

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

ZeroDisclo.com operates as a non-profit entity focused on vulnerability disclosure coordination, targeting security researchers, CERTs, and organizations. Its partnership with YesWeHack provides credibility and access to a security-focused community. The business model centers on providing technical infrastructure and legal security for vulnerability reporting rather than commercial services. Market positioning is niche but important within cybersecurity. The platform's growth potential lies in expanding partnerships and enhancing disclosure processes. No direct revenue streams or monetization models are evident from the content. The ecosystem includes CERTs and security researchers as key stakeholders.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and domain transfer protections in place. However, the lack of DNSSEC, security headers (such as CSP, HSTS), and explicit incident response contacts indicates room for improvement. No vulnerabilities or exposed sensitive data were detected in the content. Privacy compliance is partial with a privacy policy but no cookie consent mechanism. Incident response readiness and security culture indicators are limited due to missing explicit policies and contacts. Overall, the security posture is adequate for a non-profit platform but should be enhanced to meet best practices and regulatory expectations.

Recommendations

  1. Enable DNSSEC to improve domain security and prevent DNS spoofing.
  2. Implement comprehensive security headers including Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options.
  3. Publish a detailed security policy and provide explicit incident response contact channels such as security@ or abuse@ emails.
  4. Add a cookie consent mechanism if cookies or tracking technologies are used to improve privacy compliance.
  5. Enhance contact transparency by providing verified company contact emails and phone numbers on the website.

Technical notes

Notes

The website uses a modern JavaScript stack with Vue.js and Quasar Framework, indicating a contemporary front-end approach. Hosting is managed by Gandi SAS, a reputable registrar and hosting provider. Performance is moderate with good mobile optimization but basic accessibility and SEO features. No CMS detected, suggesting a custom-built platform. No analytics or tracking scripts were found in the provided HTML, indicating minimal user tracking. The site uses HTTPS but lacks advanced security headers. Overall, the technical infrastructure is solid but could benefit from enhanced security 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.
