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

Bonk.io is a small technology company operating a multiplayer physics-based online game that supports up to eight players simultaneously. The game emphasizes strategy and skill, offering both last man standing and team-based matches, along with a robust community-driven level editor. The website reflects a niche gaming platform with a legacy transition from Flash to HTML5 technology, maintaining user accounts and content continuity. The company Multiplayer.GG, based in Great Britain, has maintained the domain since 2013, indicating stable operations and a dedicated user base. Technically, the website employs modern web technologies including HTML5, JavaScript, and integrates third-party services such as Google Analytics and Amazon Publisher Services for advertising and tracking. DNS is managed via Cloudflare, enhancing reliability and security. However, the site lacks visible advanced security headers and DNSSEC is not enabled, which are areas for improvement. The site is moderately optimized for performance and mobile use, with basic accessibility and SEO features. From a security perspective, the site uses HTTPS (implied by external scripts loaded over HTTPS) but lacks explicit security policies or incident response contacts. No privacy policy or terms of service pages were found, though a cookie consent mechanism is implemented via a third-party privacy management service. The WHOIS data is consistent and trustworthy, with no privacy protection masking ownership, supporting legitimacy. No adult or questionable content is present, making the site safe for general audiences. Overall, Bonk.io presents a credible and functional gaming platform with room for enhancement in security posture and privacy compliance. Strategic improvements in security headers, DNSSEC, and publishing clear privacy and security policies would strengthen trust 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

8 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

Bonk.io occupies a niche in the online multiplayer gaming market, leveraging community-generated content and a physics-based gameplay mechanic. Its competitive advantage lies in its legacy user base transitioning from Flash to HTML5, preserving user data and content. The business model appears to be free-to-play with monetization through advertising networks such as Amazon Publisher Services and Longitude. Target customers are casual and competitive gamers worldwide. The partnership ecosystem includes related gaming sites like hitbox.io and supercarstadium.com, indicating a community or networked approach. Growth indicators include continuous updates and a large repository of user-generated maps. The company operates as a small entity with a focused product offering and a consistent brand presence.

Security posture

The security maturity of Bonk.io is moderate. The use of Cloudflare DNS and domain status flags like clientDeleteProhibited indicate basic domain security awareness. However, the absence of DNSSEC and lack of visible security headers such as Content-Security-Policy or HSTS reduce the overall security posture. No explicit security or incident response policies are published, which is a compliance gap. The site uses multiple third-party scripts for analytics and advertising, which increases the attack surface and requires vigilant management. No vulnerabilities or exposed sensitive data were detected in the provided content. The site would benefit from enhanced security controls, policy transparency, and incident response readiness to improve resilience and trust.

Recommendations

  1. Enable DNSSEC to protect against DNS spoofing and improve domain security.
  2. Implement HTTPS enforcement with HSTS headers to ensure secure connections.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Publish a comprehensive privacy policy and terms of service to improve compliance and user trust.
  5. Establish and publicize a security policy and incident response contact to enhance transparency and readiness.

Technical notes

Notes

The website is built on a modern HTML5 and JavaScript stack, replacing the legacy Flash platform. It integrates multiple third-party services for analytics and advertising, including Google Analytics, Google Tag Manager, and Amazon Publisher Services. DNS is managed by Cloudflare, providing performance and security benefits. The site uses asynchronous script loading to optimize performance but lacks advanced SEO and accessibility features. Mobile optimization is basic but functional. The absence of a CMS suggests a custom or lightweight framework. Performance is moderate, with potential improvements in caching and resource optimization. Technical risks include reliance on multiple external scripts and lack of visible security headers, which could impact security and user trust.
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.
