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

tanX is a newly established decentralized exchange platform targeting institutional traders, exchanges, and liquidity providers. The company, BRS Tech, registered in the British Virgin Islands in December 2023, positions itself as a high-performance, self-custodial liquidity network. The website presents a professional and modern design built on the Framer platform, integrating Google Analytics and Tag Manager for tracking. While the technical infrastructure is sound with HTTPS and modern web technologies, the absence of privacy and cookie policies and minimal contact information on the website indicate areas for improvement in compliance and transparency. Security posture is adequate but could benefit from enhanced domain security measures such as DNSSEC and published security policies. Overall, tanX appears to be a legitimate emerging player in the institutional DEX market, but it should enhance its privacy compliance and security disclosures to build greater trust.

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.

Priority findings

7 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

  2. 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';…

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

tanX operates in the blockchain and decentralized finance (DeFi) sector, focusing on institutional liquidity solutions. Its business model revolves around providing a decentralized exchange platform that emphasizes reliability and self-custody, appealing to professional traders and institutions. The offshore registration in the British Virgin Islands may be for regulatory or privacy reasons, common in crypto startups. The company leverages modern web technologies and analytics but lacks visible partnerships or certifications. Growth potential exists given the niche market focus, but transparency and compliance enhancements are recommended to strengthen market credibility.

Security posture

The website employs HTTPS and integrates standard security practices but lacks DNSSEC and explicit security headers, which are recommended for enhanced protection. No vulnerabilities or exposed sensitive data were detected in the analysis. However, the absence of published security policies, incident response contacts, or vulnerability disclosure mechanisms limits the site's security maturity. The use of offshore registration with minimal contact details may raise concerns for some stakeholders. To improve security posture, tanX should implement DNSSEC, publish security and incident response policies, and consider adding security.txt or vulnerability disclosure information.

Recommendations

  1. Implement DNSSEC to enhance domain security and prevent DNS spoofing.
  2. Publish comprehensive privacy and cookie policies to comply with GDPR and other regulations.
  3. Add explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Provide clear contact information and security incident response channels on the website.
  5. Consider transparency improvements including certifications or trust seals to boost credibility.

Technical notes

Notes

tanX's website is built using the Framer platform, leveraging Google Tag Manager and Google Analytics for tracking user interactions. The site is mobile-optimized with good SEO meta tags and Open Graph data for social sharing. Hosting appears to be managed via the registrar's DNS parking service, with some technical errors noted in nameserver responses. Performance is moderate with no major issues detected. Accessibility features are basic but present. The technical stack is modern but could benefit from enhanced security configurations and more robust compliance implementations.
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.
