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

DefiLlama is a specialized DeFi analytics platform founded in 2020, offering comprehensive multi-chain decentralized finance metrics including TVL, stablecoin market caps, DEX volumes, and protocol rankings. It serves a target audience of DeFi users, crypto investors, and blockchain analysts by providing transparent, ad-free, and accurate data dashboards and APIs. The platform also extends services with related products such as LlamaPay for crypto payments and LlamaSwap as a no-fee DEX aggregator, positioning itself as a leading data provider in the DeFi ecosystem. Technically, DefiLlama employs modern web technologies including React and Next.js, hosted on Cloudflare infrastructure, ensuring fast performance, good mobile optimization, and accessibility. The site uses ECharts for data visualization and integrates minimal user tracking via Plausible Analytics, reflecting a privacy-conscious approach. The domain registration is stable and transparent, with a long-term expiry and no privacy protection, consistent with a legitimate business. From a security perspective, the website enforces HTTPS, implements key security headers, and avoids exposing sensitive data. However, it lacks explicit published security policies or incident response contacts, and does not provide a cookie consent mechanism, which are areas for improvement. Overall, the security posture is strong but could benefit from enhanced transparency and compliance features. The overall risk assessment is low, with the platform demonstrating professionalism, technical maturity, and business credibility. Strategic recommendations include enabling DNSSEC, publishing security and incident response policies, implementing cookie consent for GDPR compliance, and considering a vulnerability disclosure program to further enhance trust and security culture.

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

5 findings rated critical or high. Fix these first.

  1. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  2. 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 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';…

  3. 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

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

DefiLlama occupies a strong market position as a leading DeFi analytics provider with a clear focus on transparency and comprehensive multi-chain data coverage. Its business model revolves around providing free and subscription-based data dashboards, API access, and custom analytics services. Revenue streams likely include subscriptions and partnerships with related crypto services. The platform targets crypto investors, developers, and analysts seeking reliable DeFi metrics. Growth indicators include expanding chain coverage and additional services like LlamaPay and LlamaSwap. The partnership ecosystem is evident with related domains and services under the DefiLlama brand. Operationally, the company maintains a professional web presence with consistent branding and high-quality content.

Security posture

DefiLlama demonstrates a mature security posture with HTTPS enforcement, robust security headers, and no visible exposure of sensitive data. The use of Cloudflare DNS and clientTransferProhibited domain status adds to domain security. However, the absence of a published security policy, incident response plan, or dedicated security contact reduces transparency and may impact incident handling readiness. No vulnerabilities or outdated libraries were detected in the provided content. GDPR compliance is partially addressed via a comprehensive privacy policy but lacks explicit cookie consent mechanisms. Overall, the platform is secure but should enhance its compliance and incident response transparency to align with best practices.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and readiness.
  3. Implement a cookie consent banner or mechanism to comply fully with GDPR and other privacy regulations.
  4. Consider establishing a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  5. Enhance contact information availability, including direct emails or phone numbers for support and security inquiries, to build trust.

Technical notes

Notes

The website is built using modern web technologies including React and Next.js, leveraging server-side rendering for performance. It uses ECharts for interactive data visualization and is hosted on Cloudflare infrastructure, ensuring fast load times and global availability. The site is mobile-optimized with responsive design and accessibility features. SEO is well addressed with proper meta tags and Open Graph data.

Opportunities exist to improve compliance-related technical features such as cookie consent and security policy integration.
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.
