0–100, higher is better. How it is calculated

1inch Network is a prominent decentralized finance (DeFi) platform founded in 2019, offering a comprehensive ecosystem of products including token swapping, wallet management, portfolio tracking, and a crypto payment card. The platform aggregates liquidity from multiple decentralized exchanges (DEXes) across various blockchain networks, positioning itself as a leading DeFi aggregator with a large user base and significant total trading volume. The company is supported by the 1inch Foundation, a non-profit organization dedicated to fostering the network and its community. The website reflects a professional and consistent brand image, targeting DeFi users, crypto traders, and Web3 developers. Technically, the website leverages modern web technologies such as React and Next.js, hosted with Cloudflare DNS and CDN services. It integrates multiple analytics and marketing tools including Google Analytics, TikTok Pixel, Facebook Pixel, and others, indicating a mature digital marketing and data collection strategy. The site is mobile-optimized, fast-loading, and accessible, with good SEO practices. From a security perspective, the site enforces HTTPS, employs domain transfer protection, and provides a dedicated security page and whitepaper outlining its defense mechanisms against illicit activities in DeFi. However, DNSSEC is not enabled, and a security.txt file for vulnerability disclosure is absent. No critical vulnerabilities or exposed sensitive data were detected in the content. Overall, 1inch.io demonstrates a strong security posture, comprehensive privacy compliance, and high business credibility. The domain registration details are consistent with the business claims, enhancing trustworthiness. Strategic recommendations include enabling DNSSEC, publishing a security.txt file, and enhancing incident response contact transparency to further strengthen security and compliance.

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

1inch Network operates in the competitive DeFi sector, offering a multi-product ecosystem that caters to both end-users and developers. Its business model revolves around aggregating liquidity to provide the best token swap rates, offering wallet and portfolio management tools, and enabling crypto payments via a physical and virtual card. The platform's partnerships with major crypto projects and investment firms bolster its market position and credibility. Revenue streams likely include fees from swap transactions, liquidity provision, and possibly premium services. The target audience includes retail crypto users, institutional traders, and Web3 developers. Growth indicators include a large user base, high trade volume, and continuous product expansion. The partnership ecosystem is robust, featuring collaborations with leading wallets, exchanges, and blockchain projects, which supports network effects and ecosystem growth.

Security posture

The security maturity of 1inch.io is solid, with HTTPS enforced and domain transfer protection active. The presence of a dedicated security page and whitepaper indicates a proactive approach to security awareness and user education. The site uses multiple third-party analytics and marketing scripts, which necessitates ongoing monitoring for vulnerabilities. The absence of DNSSEC and security.txt are areas for improvement. No exposed credentials or sensitive data were found, and no visible vulnerabilities were detected in the HTML content. Incident response contact information is not explicitly provided, which could be enhanced for better readiness. Overall, the platform demonstrates a strong security culture aligned with DeFi industry standards but should address the noted gaps to maintain and improve trust.

Recommendations

  1. Enable DNSSEC to enhance DNS security and prevent spoofing.
  2. Publish a security.txt file to facilitate responsible vulnerability disclosure.
  3. Explicitly provide incident response contact channels such as security@ or abuse@ emails.
  4. Audit and monitor third-party scripts regularly to mitigate supply chain risks.
  5. Enhance security headers visibility and completeness to improve browser security.

Opportunities exist to further modernize security configurations and improve transparency around incident response and vulnerability management.
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.
