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

3 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.

    • 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

  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

      SSL Certificate Expires Soon

      SSL certificate expires in 22 days

      What to do: Renew SSL certificate before expiration

      • NIS2 21(2)(h)
      • IR 2024/2690 9.2(c): Implementing Regulation (EU) 2024/2690, Annex point 9.2(c): Cryptography
      • NIST SC-17: NIST SP 800-53 Rev. 5 SC-17: Public Key Infrastructure Certificates
    • 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

RWA.xyz operates in the intersection of finance and technology, focusing on tokenized real-world assets. Its business model revolves around providing data analytics, API services, and asset listing capabilities to a niche but growing market of digital asset professionals and institutional investors. The platform's competitive advantage lies in its comprehensive data aggregation across multiple blockchains and its trusted relationships with leading financial institutions and media. Revenue streams likely include subscription or usage fees for analytics and API access, as well as fees from asset issuers for listing services. The company maintains strategic partnerships, notably with the Tokenized Asset Coalition, enhancing its ecosystem and market reach. Growth indicators include active blog content, institutional endorsements, and a clear focus on expanding platform capabilities. The company is relatively small but well-positioned within its specialized market segment.

Security posture

The website exhibits a mature security posture with mandatory HTTPS and secure form handling. The absence of explicit security headers such as Content-Security-Policy and X-Frame-Options represents an area for improvement. No public security policies or incident response procedures are disclosed, which could limit transparency and preparedness perception. There is no vulnerability disclosure program or security.txt file, which are best practices for modern web services. The use of third-party analytics and marketing scripts is standard but requires ongoing monitoring to mitigate supply chain risks. Overall, the security risks are low but could be further mitigated by adopting additional headers, publishing security policies, and establishing a formal vulnerability disclosure channel.

Recommendations

  1. Implement a Content-Security-Policy header to mitigate cross-site scripting and related attacks.
  2. Publish a security policy and incident response plan on the website to improve transparency and stakeholder trust.
  3. Create and maintain a security.txt file to facilitate responsible vulnerability disclosure.
  4. Add additional security headers such as X-Frame-Options and X-Content-Type-Options to enhance protection against clickjacking and MIME sniffing.
  5. Regularly audit and update third-party scripts and dependencies to reduce exposure to supply chain vulnerabilities.

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.
