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

7 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 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';…

  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

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

Rubic operates in the blockchain technology and finance sectors, targeting crypto traders and developers seeking cross-chain interoperability and best rates. Its business model revolves around aggregating liquidity and protocols to offer seamless swaps and bridging, monetized through API/SDK subscriptions and the RBC token ecosystem. The platform benefits from strategic partnerships and grants from major blockchain projects, enhancing credibility and market reach. Its extensive ecosystem and developer tools position it competitively in the decentralized finance space. Growth indicators include a large user base (400k+ users), significant transaction volume ($2.388B+), and continuous ecosystem expansion. The partnership ecosystem includes exchanges like Gate.io, Probit, Uniswap, and Kraken, as well as blockchain incubators and audit firms.

Security posture

Rubic demonstrates a strong security posture with HTTPS enforcement, comprehensive third-party audits, and open-source transparency. The platform incorporates MEV protection and private RPC features to safeguard user transactions. Security headers and best practices are implemented, and no vulnerabilities or exposed sensitive data were detected in the analysis. However, the absence of explicit security policies, incident response contacts, and a security.txt file limits full transparency. The platform should enhance privacy compliance by adding cookie consent mechanisms and providing direct security contact channels. Overall, Rubic's security maturity is high, suitable for a financial technology platform handling crypto assets.

Recommendations

  1. Implement a visible cookie consent banner to comply with GDPR and enhance user privacy transparency.
  2. Publish a dedicated security policy page and provide clear incident response contact information, including security@ or abuse@ email addresses.
  3. Add a security.txt file at the root domain to facilitate vulnerability disclosure and improve security communication.
  4. Provide verified company contact emails and phone numbers on the website to improve business credibility and user trust.
  5. Regularly update and publicly share audit reports and security assessments to maintain transparency and confidence.

Technical notes

Notes

The website is built on a modern and robust technical stack including Next.js and React, ensuring fast performance and excellent mobile optimization. Integration of third-party widgets like TradingView and CoinGecko enhances functionality. Hosting appears to be via Cloudflare, providing CDN and security benefits. The site uses Google Tag Manager and Cloudflare Insights for analytics and monitoring. The codebase is clean with proper meta tags and SEO optimization. Accessibility features are present but could be further enhanced. No CMS was detected, indicating a custom-built solution. Overall, the technical infrastructure supports scalability and a high-quality user experience, with minor opportunities for improvement in privacy and security transparency.
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.
