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 services, portfolio tracking, and cross-chain swaps. The platform aggregates liquidity from multiple decentralized exchanges (DEXes) to provide users with optimal rates and secure execution. Positioned as a leading DeFi aggregator, 1inch serves a broad audience of crypto traders, Web3 developers, and DeFi enthusiasts, supported by a strong foundation entity registered in the Cayman Islands. The company maintains active partnerships with major crypto projects and financial institutions, enhancing its market presence and credibility. Technically, the website leverages modern web technologies such as React and Next.js, hosted behind Cloudflare DNS and CDN services, ensuring fast performance and excellent mobile optimization. The platform integrates multiple analytics and marketing tools including Google Analytics, TikTok Pixel, Facebook Pixel, and LinkedIn Insight Tag, with a clear cookie consent mechanism in place. The website demonstrates good SEO and accessibility practices, contributing to a professional and user-friendly experience. From a security perspective, 1inch enforces HTTPS, employs clientTransferProhibited domain status, and publishes a security whitepaper outlining its defense strategies. However, DNSSEC is not enabled, and no security.txt or explicit incident response contacts are publicly available, representing areas for improvement. No vulnerabilities or exposed sensitive data were detected in the analysis. Overall, the security posture is strong but could benefit from enhanced DNS security and formalized vulnerability disclosure mechanisms. The overall risk assessment indicates a trustworthy and mature platform with high business credibility and technical sophistication. Strategic recommendations include enabling DNSSEC, publishing a security.txt file, adding explicit security headers, and providing clear incident response contacts to further strengthen security and compliance. These measures will enhance user trust and align the platform with best practices in the rapidly evolving DeFi landscape.

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

Business profile

1inch Network holds a strong market position as a leading DeFi aggregator and protocol provider, offering a diverse range of services that cater to both end-users and developers. Its business model revolves around providing cost-efficient, secure, and user-friendly DeFi solutions, including token swaps, liquidity aggregation, limit order protocols, and cross-chain interoperability. Revenue streams likely include fees from liquidity provision and partnerships. The platform targets crypto traders, DeFi users, and Web3 developers, supported by a robust ecosystem of partners such as MetaMask, Binance Labs, and Pantera Capital. Growth indicators include a large user base (24.6M+ users), significant total volume ($707B+), and extensive liquidity sources (3.2M+). The company fosters community engagement through DAO governance and ambassador programs, reinforcing its decentralized ethos and market reach.

Security posture

1inch Network exhibits a mature security posture with enforced HTTPS, domain transfer restrictions, and a published security whitepaper. The platform integrates MEV protection and secure execution mechanisms within its protocols. While no critical vulnerabilities or exposed sensitive data were identified, the absence of DNSSEC and a security.txt file limits the transparency and ease of vulnerability reporting. Incident response contact channels are not explicitly provided, which could hinder timely communication during security events. The use of multiple third-party analytics and advertising scripts introduces potential privacy and security considerations, though mitigated by cookie consent mechanisms. Overall, the platform demonstrates strong security practices suitable for a high-profile DeFi service but should enhance formal vulnerability disclosure and DNS security.

Recommendations

  1. Enable DNSSEC to improve DNS security and prevent spoofing attacks.
  2. Publish a security.txt file to facilitate responsible vulnerability disclosure.
  3. Add explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Provide clear incident response contact information on the website.
  5. Regularly audit and monitor third-party scripts to minimize security risks.

Technical notes

Notes

The website is built using modern web technologies including React and Next.js, ensuring a performant and responsive user experience across devices. Hosting and DNS services are provided by Cloudflare, contributing to fast load times and DDoS protection. The site employs multiple analytics and marketing tools, integrating tracking pixels from Google, Facebook, TikTok, LinkedIn, and AdRoll, with a compliant cookie consent banner. The absence of a traditional CMS suggests a custom or proprietary content management approach. SEO and accessibility are well addressed, with comprehensive metadata, Open Graph tags, and structured data enhancing search engine visibility and social media integration. Technical risks are minimal, though the reliance on numerous third-party scripts requires ongoing security vigilance.
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.
