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 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

    • 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

DefiLlama holds a leading position in the DeFi analytics market, offering a broad range of services such as protocol rankings, chain comparisons, and fee tracking. Its business model revolves around data aggregation and providing value-added analytics, including a Pro subscription service and API access. The platform's commitment to transparency and ad-free content enhances its trustworthiness. Its ecosystem includes related services like LlamaSwap, LlamaPay, and LlamaFeed, indicating a growing partnership and service network. The target customers are crypto investors, developers, and analysts seeking reliable DeFi data. Growth indicators include continuous feature expansion and active community engagement via Twitter and Discord.

Security posture

The website exhibits a mature security posture with HTTPS enforced, multiple security headers present, and no visible exposure of sensitive data. The domain's clientTransferProhibited status adds protection against unauthorized transfers. However, the absence of DNSSEC and lack of published security policies or incident response contacts represent gaps in security transparency and readiness. No vulnerable libraries or security flaws were detected in the analyzed content. The use of privacy-focused analytics (Fathom) aligns with good privacy practices. Overall, the security maturity is good but could be enhanced by formalizing vulnerability disclosure and incident response mechanisms.

Recommendations

  1. Enable DNSSEC on the domain to strengthen DNS security and prevent spoofing.
  2. Publish comprehensive privacy and cookie policies to improve privacy compliance and user trust.
  3. Add a dedicated vulnerability disclosure or security.txt page to facilitate responsible reporting.
  4. Provide clear incident response contact information, such as security@ or abuse@ email addresses.
  5. Consider obtaining relevant security certifications or compliance attestations to enhance credibility.

Technical notes

Notes

The website leverages a modern technology stack centered on React and Next.js, ensuring server-side rendering and good SEO. Hosting via Cloudflare provides robust CDN and security benefits. The site is well-optimized for performance and mobile responsiveness, with preloading of fonts and images. Accessibility features such as ARIA roles and keyboard navigation hints are present. The absence of heavy advertising or tracking scripts contributes to fast load times and privacy. Technical debt appears minimal, though continuous monitoring for library updates and security patches is advised. Overall, the technical infrastructure supports a reliable and scalable user experience.
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.
