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

gbadev.net is a specialized community website dedicated to the Game Boy Advance homebrew development scene. It serves as a hub for developers and enthusiasts by providing curated resources, hosting game jams and events, and maintaining active community channels such as Discord, forums, and chat. The site is supported by sponsors like DigitalOcean and Incube8 Games, indicating external backing and community trust. The business model is community-driven, focusing on open development and resource sharing within a niche market segment. Technically, the website is built using VuePress, a modern static site generator, ensuring fast performance and good mobile optimization. It leverages Cloudflare for DNS and CDN services, enhancing availability and security. Matomo analytics is used for user tracking, although no cookie consent mechanism is present. The site lacks some security headers and privacy-related policies, which are areas for improvement. From a security perspective, the site benefits from HTTPS and domain transfer protection but lacks DNSSEC and security headers that could harden its posture. No sensitive data exposure or vulnerabilities were detected in the provided content. However, the absence of privacy and cookie policies, as well as incident response information, indicates gaps in compliance and security transparency. Overall, gbadev.net is a legitimate, well-maintained community site with good technical foundations but requires enhancements in privacy compliance and security best practices to improve trust and regulatory adherence.

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 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';…

  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

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 website occupies a niche position in the technology sector, specifically targeting Game Boy Advance homebrew developers and enthusiasts. Its competitive advantage lies in its focused community engagement, curated resources, and event hosting such as ranked game jams. Revenue streams appear limited to sponsorships and community donations via OpenCollective. The target customer segment is small but dedicated, consisting of hobbyist developers and retro gaming fans. The partnership ecosystem includes reputable sponsors and open source platforms like GitHub. Strategic observations suggest the site is community-centric with potential growth through enhanced documentation and broader outreach. SecurityPosture: The site demonstrates a moderate security maturity level with HTTPS and domain transfer protections in place. However, it lacks comprehensive security headers, privacy policies, and incident response mechanisms. Compliance with GDPR and other data protection regulations is minimal due to missing policies and consent mechanisms. The use of Matomo analytics without cookie consent may pose privacy concerns. No vulnerabilities or exposed sensitive data were found, but the site would benefit from adopting security best practices and formal policies to strengthen its security culture and incident readiness.

Security posture

The current security posture of gbadev.net is moderate. The site uses HTTPS, which is mandatory for secure communications, and the domain is protected against unauthorized transfers. However, DNSSEC is not enabled, which could improve DNS security. The absence of security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security reduces protection against common web attacks. No forms or input fields were detected, minimizing attack surface from injection or data leakage. The lack of privacy and cookie policies, as well as incident response contacts, indicates gaps in compliance and transparency. The use of Matomo analytics without visible consent mechanisms may conflict with GDPR requirements. Overall, the site is secure for its purpose but should implement additional security controls and policies to enhance protection and compliance.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS integrity and security.
  2. Implement standard security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Publish comprehensive privacy and cookie policies with explicit user consent mechanisms.
  4. Add a security policy page and incident response contact information to improve transparency and readiness.
  5. Consider creating a vulnerability disclosure policy and hosting a security.txt file to encourage responsible reporting.

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.
