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

8 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 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

    • 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

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

Jumper.exchange positions itself as a comprehensive multi-chain liquidity aggregator, leveraging partnerships such as LI.FI to enhance its service offering. Its business model focuses on providing aggregated DeFi liquidity and bridging services, catering to a growing market of crypto users requiring cross-chain interoperability. The platform's competitive advantage lies in its extensive blockchain coverage and multi-audit assurances. Revenue streams likely include transaction fees and liquidity provider incentives. The company maintains a moderate size and is relatively new, with no public parent or subsidiary affiliations detected. The presence of multiple language localizations suggests a global target audience. Strategic partnerships and integrations with established DeFi protocols enhance its market presence and growth potential.

Security posture

The website enforces HTTPS and employs domain transfer restrictions, contributing to a secure environment. However, the absence of DNSSEC reduces DNS security robustness. No explicit security policies, incident response contacts, or vulnerability disclosure mechanisms are published, which could hinder transparency and user trust. The use of privacy protection for WHOIS is justified given the crypto industry context. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. Security headers beyond HTTPS are not explicitly identified, suggesting room for enhancement. Overall, the security posture is moderate but would benefit from formalized policies and DNS security improvements.

Recommendations

  1. Enable DNSSEC on the domain to strengthen DNS security and prevent spoofing.
  2. Publish comprehensive privacy and cookie policies with clear GDPR compliance statements.
  3. Implement and publicize a security policy and incident response contact information to improve transparency.
  4. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  5. Enhance security headers (e.g., Content Security Policy, X-Frame-Options) to improve web application security.

Technical notes

Notes

The website is built using modern web technologies including React and Next.js, with Material UI for styling. It is hosted on Cloudflare, providing CDN and security benefits. The site includes multiple font preloads and CSS optimizations, indicating attention to performance. Google Analytics is integrated for traffic analysis. The site is mobile optimized and supports multiple languages, enhancing accessibility and user reach. However, DNSSEC is not enabled, and no CMS is detected, suggesting a custom-built platform. Performance is moderate with asynchronous script loading. Accessibility features are basic but present. SEO is supported with proper meta tags and Open Graph data. Overall, the technical infrastructure is modern and well-implemented but could improve DNS security and formal compliance documentation.
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.
