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

coolmathgam.es operates as a parody Mastodon instance within the fediverse, providing a niche social networking platform that mimics Mastodon but is explicitly unaffiliated with the well-known Cool Math Games site. The platform offers basic Mastodon features such as user profiles, public timelines, and trending feeds, targeting general users interested in decentralized social media. The site is small in scale with minimal active users and clear disclaimers about its parody nature. Technically, the website is built on a modern tech stack including Mastodon version 4.4.0-nightly and React, leveraging Cloudflare for hosting and analytics. The site uses HTTPS with script integrity checks, indicating a reasonable level of technical maturity. However, some standard security headers are missing, and privacy compliance mechanisms such as cookie consent banners are absent. From a security perspective, the site benefits from HTTPS and no visible vulnerabilities or exposed sensitive data. The use of privacy protection in domain registration is typical for small or parody sites, though it limits transparency. The absence of contact information, terms of service, and security policies reduces trust and compliance posture. Overall, the security posture is moderate but could be improved with additional headers and policies. The overall risk is low given the site's parody and small scale nature, but strategic improvements in privacy compliance, security headers, and transparency would enhance trustworthiness and user confidence.

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

4 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.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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 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.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

coolmathgam.es occupies a niche position as a parody Mastodon instance, leveraging the Mastodon open-source platform to provide social networking services. Its business model is community-driven and likely non-commercial, focusing on social interaction within the fediverse. The site targets general users interested in decentralized social media, with no evident revenue streams or partnerships. The small user base and lack of formal business information suggest limited growth and commercial ambitions. The site’s branding is moderately consistent, with clear disclaimers to avoid confusion with the original Cool Math Games brand. The partnership ecosystem is minimal, with no identified partners or subsidiaries. Strategic observations include the need for enhanced privacy and security policies to support potential growth and user trust.

Security posture

The security maturity of coolmathgam.es is moderate. The site employs HTTPS with strong SSL configuration and uses script integrity attributes, which are positive indicators. However, it lacks explicit security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options, which are recommended best practices. No vulnerabilities or exposed sensitive data were detected in the HTML content. Privacy compliance is weak, with no cookie consent mechanisms despite having a privacy policy. Incident response and security policy information are absent, limiting readiness for security events. The domain uses privacy protection, which is justified given the site's parody nature but reduces transparency. Overall, the security culture appears basic and would benefit from formalized policies and enhanced technical controls.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to strengthen defense against common web attacks.
  2. Add a cookie consent banner and improve privacy compliance to align with GDPR and other regulations.
  3. Publish terms of service and security policy pages to enhance transparency and user trust.
  4. Provide clear contact information including security and abuse contacts to improve incident response readiness.
  5. Enhance accessibility features and SEO optimization to improve user experience and discoverability.

Technical notes

Notes

The website is built on a modern and well-maintained technology stack centered around Mastodon 4.4.0-nightly and React. It uses ES modules and script integrity attributes, indicating attention to modern web development practices. Hosting appears to be via Cloudflare, providing performance and security benefits. The site is mobile-optimized with responsive design and basic accessibility features. Performance is moderate, with no major issues detected. However, the absence of a CMS and limited metadata beyond basic Open Graph tags suggests a minimalistic content management approach. Technical risks include missing security headers and lack of privacy consent mechanisms, which could impact compliance and security posture. Opportunities exist to modernize further by adding progressive web app features and enhanced accessibility support.
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.
