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

CometBFT is a technology-focused project delivering a consensus engine tailored for the Cosmos blockchain ecosystem. The website serves as an informational and documentation portal, targeting blockchain developers and ecosystem participants. It is stewarded by Informal Systems, lending credibility and organizational backing. The site is built using modern web technologies such as Next.js and React, providing a good user experience with responsive design and clear navigation. However, it lacks explicit privacy, cookie, and terms of service policies, as well as direct contact information, which limits its compliance posture. From a technical perspective, the website employs a modern frontend stack and loads external resources efficiently, but there is no evidence of advanced security headers or DNSSEC implementation. The domain registration is consistent with the project's timeline and uses a reputable registrar without privacy protection, supporting legitimacy. Social media presence is active on GitHub, Telegram, Twitter, and Discord, facilitating community engagement. Security posture is moderate; HTTPS is implied by the URL, but the absence of security headers and formal security policies reduces the overall security maturity. No forms or data collection mechanisms are present on the homepage, minimizing exposure to input-based vulnerabilities. No vulnerability disclosure or incident response information is provided, which could be improved to enhance trust. Overall, the website is professional and safe, with a clear focus on technology and community engagement. Strategic improvements in privacy compliance, security policies, and contact transparency would strengthen the site's trustworthiness and compliance standing.

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 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

    • 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

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

CometBFT operates as an open-source technology project within the blockchain sector, specifically targeting the Cosmos ecosystem. Its market positioning is niche, focusing on consensus engine development for blockchain infrastructure. The business model revolves around community-driven open source development, supported by Informal Systems as a steward. Revenue streams are not explicit but likely derive from ecosystem partnerships and consulting. The target customers are blockchain developers and organizations building on Cosmos. Growth indicators include active GitHub repositories and community channels on Telegram, Twitter, and Discord. The partnership with Informal Systems enhances credibility and operational support. The project is relatively new, founded in late 2022, and maintains a small organizational size. Strategic observations suggest a focus on technical excellence and ecosystem integration rather than commercial monetization at this stage.

Security posture

The website demonstrates a moderate security posture. HTTPS is used, ensuring encrypted communications. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options indicates room for improvement in mitigating common web vulnerabilities. No sensitive data or credentials are exposed in the HTML content. The lack of privacy and cookie policies, as well as no visible incident response or vulnerability disclosure mechanisms, suggests limited formal security governance and compliance. No forms or user input fields reduce attack surface but also limit user engagement options. DNSSEC is not enabled, which could enhance DNS security. Overall, the security culture appears nascent, typical for open source projects, but could benefit from formalizing policies and improving technical defenses.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies to improve compliance and user trust.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  3. Enable DNSSEC for the domain to strengthen DNS security.
  4. Provide clear contact information including security incident contacts and consider publishing a security.txt file for vulnerability disclosure.
  5. Enhance accessibility features and SEO optimization to improve user experience and discoverability.

No CMS or backend platform is detected, suggesting a static or JAMstack approach. Performance is moderate with good mobile optimization. Accessibility is basic but could be improved. SEO is basic with minimal meta tags and no structured data or Open Graph tags detected. Hosting provider details are not explicit. No analytics or tracking scripts are present, indicating minimal user tracking. The technical stack is modern and maintainable but could benefit from enhanced SEO and accessibility features.
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.
