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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Twitter, LinkedIn, YouTube, Google APIs

      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

The company operates in the technology sector, specifically within blockchain infrastructure services. Its business model revolves around providing blockchain data exploration and analytics, likely monetized through platform usage or partnerships. The presence of a partner domain (dcellar.io) suggests an ecosystem approach. The platform targets blockchain enthusiasts and developers, positioning itself as a key tool for BNB Greenfield network transparency and analysis. The company is small-sized and relatively new, with no extensive public business information or certifications disclosed.

Security posture

The website employs HTTPS and has domain registration protections enabled, which are positive security indicators. However, DNSSEC is not enabled, and no security headers were detected in the HTML content, indicating room for improvement in web security hardening. There is no published privacy policy, cookie policy, or incident response information, which are gaps in compliance and transparency. No vulnerability disclosure or security.txt files were found, limiting the platform's openness to security reporting. Overall, the security posture is moderate but could be enhanced by implementing recommended best practices.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Publish comprehensive privacy and cookie policies to improve compliance and user trust.
  3. Add security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to enhance web security.
  4. Provide clear contact information including security incident response channels and vulnerability disclosure guidelines.
  5. Implement a security.txt file to facilitate responsible vulnerability reporting and improve security culture.

Technical notes

Notes

The website is built using modern web technologies including React and Next.js, hosted on AWS infrastructure. It uses Google Tag Manager for analytics and Google Fonts for typography. The site is mobile optimized and demonstrates good accessibility and SEO practices. Performance is moderate, with deferred loading of scripts and preloading of critical CSS. The technical stack is modern and scalable, but the absence of some security headers and DNSSEC indicates minor technical debt in security configuration. Overall, the technical implementation supports a professional and functional user experience.
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.
