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

STX20 is a recently launched blockchain project focused on providing a token inscription standard based on the Stacks Blockchain network. The website serves as a platform for exploring token metadata, wallet balances, and offers features such as token inscription, wrapping, and a marketplace. The target audience primarily includes blockchain developers and token holders interested in the Stacks ecosystem. The business operates in the technology sector with a niche focus on blockchain token standards. Technically, the website is a modern single-page application likely built with React, hosted on AWS infrastructure, and uses Google Fonts and Google Tag Manager for analytics. The site demonstrates good mobile optimization and user experience, though accessibility and SEO optimizations are basic. Performance is moderate, with no critical technical issues detected. From a security perspective, the site uses HTTPS and standard domain registration practices but lacks DNSSEC and important security headers. There is no published privacy, cookie, or security policy, and no incident response contacts are provided. Analytics tracking is implemented via Google Tag Manager, but privacy compliance is poor due to missing policies and consent mechanisms. The domain is newly registered, consistent with the project's launch timeline, and shows no suspicious WHOIS patterns. Overall, the website is functional and professional but would benefit from enhanced security practices, privacy compliance, and clearer contact information to improve trust and compliance posture.

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

10 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. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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';…

  3. 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

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

STX20 positions itself as a specialized provider of token inscription standards within the Stacks blockchain ecosystem. Its competitive advantage lies in being an early standard for token metadata and inscription on Stacks, targeting blockchain developers and token users. The business model revolves around providing protocol documentation, exploration tools, and a marketplace for token inscriptions. Revenue streams are not explicitly detailed but may include marketplace fees or related services. The project is small and newly founded in 2023, with no parent or subsidiary companies identified. Partnerships are implied through social media and GitHub presence but no formal partner domains are listed. Growth indicators include active social channels and ongoing development reflected in the website's features.

Security posture

The security maturity of the STX20 website is moderate. HTTPS is enforced, and domain registration is handled by a reputable registrar with standard domain status protections. However, the absence of DNSSEC and security headers such as Content-Security-Policy and Strict-Transport-Security reduces the overall security posture. No vulnerability disclosures or incident response policies are published, which limits transparency and readiness for security incidents. Analytics tracking is present but lacks clear privacy compliance measures. There are no visible vulnerabilities or exposed sensitive data in the HTML content. To improve, the project should implement security headers, publish security and privacy policies, enable DNSSEC, and provide incident response contacts.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement and publish comprehensive privacy and cookie policies with user consent mechanisms to improve GDPR compliance.
  3. Add security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to harden the website against common attacks.
  4. Provide clear contact information including security incident response and general support channels to increase trust and transparency.
  5. Regularly audit and update third-party libraries and analytics configurations to minimize potential vulnerabilities and privacy risks.

Technical notes

Notes

The website is built as a React single-page application, leveraging modern web technologies and hosted on AWS infrastructure as indicated by DNS nameservers. It uses Google Fonts for typography and Google Tag Manager for analytics tracking. The site is mobile optimized with responsive design and good navigation clarity. Performance is moderate, with no major technical debt or errors detected in the HTML content. SEO is basic with standard meta tags and Open Graph data but lacks advanced structured data such as JSON-LD. Accessibility features are minimal but functional. The absence of CMS suggests a custom or static site build. Overall, the technical implementation is solid for a small blockchain project but could benefit from enhanced SEO and accessibility improvements.
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.
