Risk levelMedium

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

Cyber.co is a technology company specializing in Ethereum Layer 2 blockchain solutions aimed at enabling Web3 social applications. The company offers innovative services such as crypto staking and restaking to enhance network security. The website presents a professional and modern design built with Next.js and React, hosted on AWS infrastructure. The technical implementation is solid with good mobile optimization and SEO practices, although some accessibility features could be improved. Security posture is adequate with HTTPS enabled and domain lock status, but lacks DNSSEC and security headers. Privacy compliance is weak due to absence of privacy and cookie policies, and no contact information is provided. Overall, Cyber.co appears to be a legitimate and established player in the blockchain technology sector with room for improvement in transparency and security best practices.

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

7 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"

  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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Twitter

      What to do: Document all third-party data sharing in your privacy policy

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

Cyber.co positions itself as an innovative Ethereum Layer 2 solution provider targeting Web3 developers and crypto users. The business model revolves around blockchain scalability and security via staking mechanisms. The domain age of over 13 years supports a mature presence in the market. External links to ecosystem grants, governance, forums, and documentation indicate an active community and partnership ecosystem. The company operates primarily in the technology sector within the US. Lack of explicit business contact details and certifications limits full business credibility assessment. The website content is relevant and professionally presented, supporting a moderate trust level.

Security posture

The website employs HTTPS with a reputable registrar and domain lock status to prevent unauthorized changes. However, DNSSEC is not enabled, which is a recommended security enhancement to protect against DNS spoofing. No security headers were detected in the provided data, and there is no published security policy or incident response contact information. The absence of privacy and cookie policies indicates compliance gaps with GDPR and other privacy regulations. No vulnerability disclosure or security.txt files were found, limiting transparency in security practices. Overall, the security posture is moderate but could be significantly improved by adopting standard security headers, enabling DNSSEC, and publishing clear security and privacy policies.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing attacks.
  2. Implement and publish comprehensive privacy and cookie policies with user consent mechanisms to improve GDPR compliance.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to strengthen web security.
  4. Provide clear contact information including security incident response channels (e.g., security@ or abuse@ emails) to improve transparency and trust.
  5. Consider publishing a vulnerability disclosure policy or security.txt file to encourage responsible reporting and demonstrate security maturity.

Technical notes

Notes

The website is built using modern web technologies including React and Next.js, indicating a contemporary and maintainable tech stack. Hosting is provided via AWS DNS services, suggesting reliable infrastructure. Performance is moderate with good mobile optimization and SEO meta tags present. Accessibility features are basic and could be enhanced to meet broader standards. No CMS was detected, implying a custom or framework-based site. The site uses multiple JavaScript chunks and stylesheets typical of Next.js applications. There is no evidence of outdated or vulnerable libraries in the provided data. Overall, the technical infrastructure is solid but could benefit from enhanced accessibility and security configurations.
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.
