Risk levelLow

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

Cronos is a blockchain platform focused on integrating real-world finance with on-chain technology, leveraging EVM compatibility and AI readiness. It benefits from a strategic partnership with Crypto.com, enabling access to a large user base and robust liquidity. The platform supports a growing ecosystem of decentralized applications and offers multiple blockchain layers including EVM, zkEVM, and POS chains. Technically, the website is built with modern frameworks such as React and UmiJS, hosted with Cloudflare DNS, and employs Google Tag Manager and OneTrust for analytics and cookie consent. Security posture is strong with HTTPS, domain lock statuses, and a cookie consent mechanism, though DNSSEC is not enabled and explicit privacy and security policies are not publicly found. Overall, the site is professional, well-branded, and trustworthy with no blocking or WAF challenges detected.

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

2 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. 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

Cronos positions itself as a key player in the blockchain and DeFi space, targeting developers, institutional and retail users, and leveraging Crypto.com's ecosystem. Its business model centers on providing blockchain infrastructure, developer grants, and bridging solutions to connect with Cosmos and Ethereum chains. The platform's large transaction volume, user base, and ecosystem partnerships indicate strong market presence and growth potential. The absence of direct contact information and formal privacy/legal documents on the site suggests room for improvement in transparency and compliance communication.

Security posture

The website demonstrates a mature security posture with HTTPS enforced, domain registration locked with multiple EPP status flags, and use of Cloudflare DNS. The presence of a cookie consent banner indicates awareness of privacy compliance. However, the lack of DNSSEC and absence of published security policies or incident response contacts are gaps. No vulnerabilities or exposed sensitive data were detected in the content. The site would benefit from publishing a security.txt file and explicit incident response information to enhance trust and readiness.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Publish a comprehensive privacy policy and terms of service accessible from the main site.
  3. Add explicit security policy and incident response contact information, including security@ or abuse@ emails.
  4. Provide clear company contact information including emails and phone numbers to improve transparency.
  5. Consider publishing a vulnerability disclosure policy or security.txt file to encourage responsible reporting.

Technical notes

Notes

The website uses a modern React-based framework (UmiJS 3.5.20) with Cloudflare DNS and CDN services, ensuring fast and reliable delivery. Google Tag Manager is used for analytics, and OneTrust manages cookie consent, indicating compliance efforts. The site is mobile optimized with responsive design and good SEO metadata including Open Graph and Twitter cards. No CMS was detected, suggesting a custom or static site build. Performance is fast with no blocking detected. Accessibility is basic but present. The technical stack is well-chosen for scalability and user experience, though improvements in accessibility and privacy documentation are recommended.
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.
