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

Cactus Comments is an open source federated comment system built on the Matrix protocol, targeting web developers and website owners who want decentralized, privacy-respecting comment functionality. The project is small and community-funded, with source code openly available under LGPLv3 and AGPLv3 licenses. The website is professionally designed with good content quality and clear navigation, reflecting a mature open source project. Technically, it uses modern web standards and is hosted on Hetzner, a reputable provider. However, there are gaps in privacy compliance and security policies, with no visible privacy or cookie policies and no incident response information published. The security posture is moderate, with HTTPS implied but no explicit security headers detected. Overall, the domain registration is privacy protected but consistent with the nature of the project, and no suspicious patterns were found.

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

6 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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

    • 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

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.

Dark web exposure

Add-on

Leaked records that mention cactus.chat, from OffSeq Breach.

No leaked records found

Breach holds no records for cactus.chat right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.

Technical appendix

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

Business context

Business profile

The project occupies a niche in the open web ecosystem by providing a federated commenting system leveraging the Matrix protocol, which differentiates it from centralized comment platforms. Its open source business model relies on community funding via OpenCollective, indicating a non-commercial but sustainable approach. The target audience includes developers and open web advocates. The project maintains transparency through public repositories and demo sites but lacks formalized privacy and security documentation, which could impact trust with enterprise users. The absence of direct contact information suggests a community-driven support model rather than commercial customer service.

Security posture

The website demonstrates a basic to moderate security posture. HTTPS is used, and no sensitive data is exposed in the HTML content. However, the absence of security headers such as Content-Security-Policy and Strict-Transport-Security reduces protection against common web attacks. No vulnerability disclosure or security.txt files are present, limiting clear communication channels for security issues. The WHOIS privacy protection is justified and does not raise suspicion. The lack of privacy and cookie policies is a compliance gap, especially under GDPR. Incident response readiness appears minimal due to missing contact channels for security matters.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy to improve GDPR compliance and user trust.
  2. Implement and serve security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Add a security.txt file or vulnerability disclosure page to facilitate responsible vulnerability reporting.
  4. Provide clear contact information or a dedicated security contact email to improve incident response readiness.
  5. Enable DNSSEC on the domain to enhance DNS security and integrity.

Technical notes

Notes

The website uses a modern tech stack with HTML5, CSS, and JavaScript, and leverages the Matrix protocol for its core functionality. Hosting is provided by Hetzner, a reliable European hosting provider. The site is mobile optimized and performs well with fast loading times. The use of script integrity attributes indicates attention to security in resource loading. However, no CMS or major frameworks are detected, suggesting a custom or lightweight implementation. The absence of analytics or tracking scripts aligns with privacy-respecting principles but limits marketing insights. Technical debt appears low, but improvements in security headers and privacy documentation are recommended to reduce risk.
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.
