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

Sturdy Finance is a decentralized finance platform specializing in isolated lending with shared liquidity, leveraging AI-optimized yields powered by its Bittensor subnet. The platform targets DeFi users including lenders, borrowers, and project teams, offering permissionless asset onboarding and risk-isolated pools aggregated for deep liquidity. Supported by prominent investors such as SoftBank, Pantera Capital, and Y Combinator, Sturdy positions itself as an innovative player in the DeFi lending market. Technically, the website is built on modern frameworks like Next.js and React, hosted on Vercel, ensuring fast performance and excellent mobile optimization. Security is a strong focus with multiple third-party audits and an active bug bounty program on Immunefi. However, the absence of explicit privacy and cookie policies and lack of direct contact information on the website are notable gaps. WHOIS data is unavailable, which slightly reduces domain trust but is somewhat mitigated by the platform's transparency in audits and investor backing. Overall, Sturdy presents a professional, secure, and credible DeFi lending solution with room for improvement in privacy compliance and contact transparency.

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 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

    • 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

Sturdy operates in the competitive DeFi lending sector, differentiating itself through a novel two-tier architecture that isolates risk while unifying liquidity. Its business model revolves around enabling users to create liquid money markets for any token quickly, supported by AI-driven yield optimization. Revenue likely derives from lending fees and yield aggregation services. The platform's partnership ecosystem includes top-tier venture capital and blockchain-focused investors, enhancing credibility and growth potential. The presence of multiple audits and a bug bounty program signals a mature security culture. Target customers are crypto lenders, borrowers, and token project teams seeking efficient liquidity solutions. The website's content and design reflect a focus on professionalism and user engagement, supporting market positioning as a trustworthy DeFi protocol.

Security posture

Sturdy demonstrates a mature security posture with enforced HTTPS, comprehensive third-party audits by Spearbit, ChainSecurity, and Zellic, and a public bug bounty program on Immunefi. The website does not expose sensitive data and employs modern security headers, contributing to a strong defense against common web threats. However, the lack of a published security policy or incident response contact details on the website limits transparency for security incident handling. GDPR compliance indicators and privacy policy disclosures are absent, representing compliance gaps. Overall, the platform is secure but could enhance user trust by publishing detailed security and privacy documentation and establishing clear incident response channels.

Recommendations

  1. Publish comprehensive privacy and cookie policies prominently on the website to improve privacy compliance.
  2. Add clear and accessible contact information, including security incident contacts and general support emails.
  3. Implement and publish a security.txt file to facilitate responsible vulnerability disclosure.
  4. Enhance GDPR compliance by detailing data protection practices and user rights.
  5. Provide more detailed business registration and legal information to strengthen business credibility.

Notes

The website is built using a modern technology stack including React and Next.js, hosted on Vercel, which ensures fast loading times and excellent mobile responsiveness. The use of Tailwind CSS contributes to consistent and scalable styling. Analytics are implemented via Vercel Analytics, providing minimal user tracking. The site structure is clear with well-organized navigation and semantic HTML, supporting good SEO and accessibility. No CMS is detected, indicating a custom or static site approach. The technical implementation is robust with no visible technical debt or performance bottlenecks. Opportunities exist to improve privacy and compliance documentation and to enhance security transparency.
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.
