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. 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 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 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 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

Celo operates in the blockchain technology and finance sectors, positioning itself as an Ethereum Layer 2 scaling solution provider. Its business model revolves around enabling fast, low-cost payments and DeFi applications, targeting developers, financial institutions, and end-users seeking financial inclusion. The company benefits from a mature domain and consistent branding. The lack of explicit privacy and security policies on the website suggests room for improvement in regulatory compliance. The integration of Google Analytics indicates moderate user tracking for business intelligence. No suspicious or unrelated domains were found linked. The company appears to be medium-sized with a focus on technology innovation in the blockchain space.

Security posture

The website employs HTTPS and has domain status flags to prevent unauthorized changes, which are positive security indicators. However, DNSSEC is not enabled, which is a recommended best practice to prevent DNS spoofing. No security headers such as Content-Security-Policy or X-Frame-Options were detected in the provided content, which could improve protection against common web attacks. There is no visible security or incident response policy or contact information for reporting security issues. The absence of privacy and cookie policies also indicates compliance gaps with GDPR and similar regulations. Overall, the security posture is moderate but could be enhanced with additional technical and policy measures.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Publish comprehensive privacy and cookie policies on the website to improve transparency and GDPR compliance.
  3. Implement and configure security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Add a dedicated security or incident response page with contact channels for vulnerability reporting.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy risks and improve user trust.

Technical notes

Notes

The website is built using Framer, a modern web design platform, and uses Cloudflare for DNS services. Google Analytics and Tag Manager are integrated for user tracking and analytics. The site is mobile optimized and has good SEO metadata including Open Graph and Twitter cards. Performance is moderate with no evident blocking issues. The domain is registered with Squarespace Domains II LLC and has a long registration period, indicating stability. However, DNSSEC is not enabled, and no advanced security headers were detected. The site lacks visible forms or data collection fields in the analyzed content. Overall, the technical infrastructure is modern but could benefit from enhanced security configurations and privacy compliance 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.
