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

5 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"

    • 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';…

  2. 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

    • 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

  3. 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

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

RSS3 operates in the emerging decentralized data infrastructure market, targeting developers, AI practitioners, and Web3 users. Its competitive advantage lies in providing an open information layer that aggregates data from blockchains, decentralized social networks, and traditional web sources. The business model appears to focus on network participation, node operation, and enabling third-party applications. The company actively engages in ecosystem partnerships and community events, enhancing its market position. Growth indicators include increasing API calls, integration with popular protocols, and AI product launches. The company is headquartered in the Cayman Islands under Natural Selection Group Limited, founded in 2021, indicating a relatively young but active enterprise.

Security posture

The website demonstrates a good security maturity level with enforced HTTPS, domain status protections, and no visible sensitive data exposure. However, it lacks explicit published security policies, incident response contacts, and vulnerability disclosure mechanisms. The absence of a cookie consent mechanism may pose compliance risks under GDPR. No vulnerable libraries or security flaws were detected in the analyzed content. The security culture appears proactive but could benefit from enhanced transparency and formalized policies to improve trust and compliance.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and readiness.
  3. Implement a cookie consent banner/mechanism to comply with GDPR and other privacy regulations.
  4. Add explicit security headers such as Content-Security-Policy and X-Frame-Options to strengthen web security.
  5. Regularly audit third-party scripts and dependencies to identify and mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on a modern technology stack including React and Next.js, ensuring good performance and SEO optimization. Hosting appears to leverage Cloudflare DNS services, contributing to fast loading times and reliability. The site is mobile-optimized with responsive design and accessibility considerations. Integration with Google Tag Manager enables analytics and marketing tracking, though privacy compliance could be improved. The use of Storyblok CMS is inferred from asset URLs, supporting content management. Overall, the technical infrastructure is robust and well-suited for a decentralized data network platform, with opportunities to enhance security and privacy features.
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.
