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

YesWeHack Dojo is a cybersecurity training platform launched in 2020 by YesWeHack, a recognized player in the bug bounty and security community. The platform offers free Capture The Flag (CTF) challenges and training modules designed to enhance hacking skills for beginners and experienced security researchers alike. It integrates with the broader YesWeHack ecosystem, providing users opportunities to participate in bug bounty programs and gain recognition. Technically, the website is built using modern frameworks such as Nuxt.js and Vue.js, styled with Tailwind CSS, and employs Matomo for analytics. The site is hosted under a reputable registrar, Gandi SAS, and uses HTTPS with a good SSL configuration. The site is mobile-optimized and provides a good user experience with clear navigation and professional design. From a security perspective, the platform enforces HTTPS and has domain transfer protections in place. However, it lacks DNSSEC and some recommended security headers. Privacy compliance is partially addressed with a comprehensive privacy policy, but no cookie consent mechanism is present despite tracking usage. No explicit incident response contacts or security.txt file were found. Overall, YesWeHack Dojo presents a trustworthy and professional platform for cybersecurity education with a solid technical foundation. Strategic improvements in security headers, cookie consent, and incident response transparency would further enhance its security posture and compliance.

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

5 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 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 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

  3. 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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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.

Business context

Business profile

YesWeHack Dojo operates as a free educational platform targeting cybersecurity learners and bug bounty hunters. Its business model leverages community engagement and integration with the YesWeHack bug bounty platform to attract and retain users. The company positions itself as a leader in cybersecurity training and bug bounty facilitation, with a medium-sized operation based in France. The platform benefits from strong branding consistency and trust signals such as HTTPS and official social media channels. The absence of direct contact information on the site suggests a focus on digital engagement rather than direct sales or support. The ecosystem includes related domains such as yeswehack.com, which serves as the parent corporate site. The platform's monthly challenges and playground mode encourage active participation and skill development, supporting growth and community building. Partnerships and resources linked from the site indicate a well-established presence in the cybersecurity industry.

Security posture

The security posture of YesWeHack Dojo is solid but with room for improvement. The site uses HTTPS with a valid SSL certificate and has domain transfer protections enabled, which are positive indicators. However, DNSSEC is not enabled, which could be a potential risk for DNS spoofing attacks. The absence of key security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security reduces the defense-in-depth. No exposed sensitive data or vulnerable libraries were detected in the provided content. The site does not appear to collect sensitive user data on the main pages, and no forms with input fields were found. Privacy compliance is partially met with a privacy policy, but cookie consent mechanisms are missing despite the use of Matomo analytics, which tracks user behavior. Incident response information and security.txt files are not present, which could hinder vulnerability reporting and incident handling. Overall, the platform demonstrates good baseline security but should enhance its headers, privacy controls, and incident response transparency to improve its security maturity.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement and display a cookie consent banner to comply with GDPR and inform users about tracking.
  3. Add essential security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Publish a security.txt file to provide clear vulnerability disclosure and incident response contacts.
  5. Consider adding explicit contact information or support channels to improve user trust and compliance.

Technical notes

Notes

The website is built on a modern JavaScript framework stack, primarily Nuxt.js and Vue.js, with Tailwind CSS for styling. This combination supports responsive design and good user experience across devices. The use of Matomo analytics indicates a preference for privacy-conscious tracking over third-party services like Google Analytics. Hosting appears stable and is managed via Gandi SAS, a reputable registrar and hosting provider. The site loads multiple JavaScript modules and CSS files efficiently, though performance is assessed as moderate, suggesting potential optimization opportunities. No CMS was detected, indicating a custom or framework-based site rather than a traditional CMS like WordPress. The technical implementation is clean with valid HTML and CSS, but accessibility features are basic and could be enhanced. SEO is supported with proper meta tags and Open Graph data, improving social sharing and search visibility. Overall, the technical infrastructure is modern and well-implemented, with opportunities to improve performance and accessibility.
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.
