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

4 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

  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

Rango Exchange operates in the competitive DeFi aggregator market, differentiating itself by supporting a wide range of blockchains and protocols, including UTXO, EVM, Cosmos, and others. Its business model revolves around providing seamless cross-chain interoperability through APIs, SDKs, and no-code widgets, targeting dApp developers and crypto users. The company has secured backing from notable investors and maintains partnerships with top wallets and protocols, enhancing its market credibility. The platform's growth is supported by extensive integrations and a user-centric approach emphasizing non-custodial, no-KYC swaps. Strategic observations include the importance of expanding security transparency and incident response readiness to further build trust.

Security posture

Rango Exchange demonstrates a mature security posture with enforced HTTPS, domain transfer protection, and privacy-conscious cookie consent defaults. The absence of exposed sensitive data and references to audits indicate attention to security. However, the lack of a published security policy, incident response contacts, and vulnerability disclosure mechanisms represents gaps in transparency and readiness. DNSSEC is not enabled, which is a recommended improvement. Overall, the platform balances security with usability but should enhance its public security documentation and DNS security to align with best practices.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS integrity and prevent spoofing.
  2. Publish a dedicated security policy and incident response contact information on the website.
  3. Implement and verify comprehensive security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Establish and publicize a vulnerability disclosure program and security.txt file to encourage responsible reporting.
  5. Continue enhancing privacy and cookie consent mechanisms to maintain GDPR and global compliance.

Technical notes

Notes

The website is built using Next.js and React, indicating a modern and scalable front-end architecture. Hosting leverages Cloudflare DNS, likely with CDN benefits, contributing to fast load times and good performance. The site is mobile-optimized with responsive design and accessibility considerations. SEO is well addressed through meta tags, Open Graph, and structured JSON-LD data. No CMS is detected, suggesting a custom or static site generation approach. The technical stack supports extensibility via APIs, SDKs, and widgets, aligning with the business model of integration and developer enablement. Technical risks are minimal, with recommendations focusing on enhancing DNS security and security header implementation.
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.
