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

Silo Finance operates as a non-custodial decentralized finance (DeFi) platform specializing in high-yield, risk-isolated money markets for lending and borrowing crypto assets across Ethereum and EVM-compatible chains. The platform offers a suite of services including lending, borrowing, liquidity management via Silo Vaults, developer tools for building custom lending infrastructure, and token staking/governance through the SILO/xSILO token evolution. Positioned as an innovative player in the DeFi space, Silo emphasizes risk isolation and cross-chain interoperability to attract crypto lenders, borrowers, and developers. Technically, the website is built on Webflow CMS with modern web technologies including Google Fonts, jQuery, and integration with The Graph API and Chainlink CCIP for blockchain data and cross-chain token transfers. Hosting is via AWS Cloudfront CDN, ensuring moderate performance and good mobile optimization. The site features rich multimedia content, clear navigation, and comprehensive developer and user documentation, reflecting a mature digital presence. From a security perspective, Silo Finance demonstrates strong commitment through multiple third-party audits, formal verification of its codebase, a substantial bug bounty program, and live event monitoring. However, some improvements are recommended such as adding explicit security headers, publishing a security.txt file, and implementing cookie consent mechanisms to enhance GDPR compliance. No critical vulnerabilities or exposed sensitive data were detected. Overall, Silo Finance presents a trustworthy and professional DeFi platform with a solid security posture and a well-executed web presence. The lack of WHOIS transparency is typical for crypto projects and does not detract significantly from legitimacy. Strategic recommendations include enhancing privacy compliance, improving security header implementation, and providing clearer incident response contacts to further strengthen trust 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

8 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

Silo Finance is positioned as a specialized DeFi lending and borrowing protocol focusing on risk-isolated money markets, targeting crypto asset holders and developers seeking customizable lending infrastructure. Its business model revolves around non-custodial finance, earning revenue through lending interest, borrowing fees, liquidity incentives, and governance token utility. The platform's competitive advantages include risk isolation, cross-chain interoperability, and a developer-friendly hooks stack for custom deployments. Partnerships with security audit firms and analytics platforms enhance credibility. Growth indicators include active governance, multiple chain deployments, and a substantial bug bounty program. The ecosystem is supported by integrations with Chainlink, The Graph, and community engagement via Discord, Telegram, and Github.

Security posture

Silo Finance exhibits a mature security posture with multiple comprehensive audits from reputable firms (Certora, Sigmap Prime, Spearbit Cantina, Enigma), formal verification, and a $350,000 bug bounty program hosted on Immunefi. The platform also participates in live event monitoring and has signed the Security Alliance’s Safe Harbor Agreement, indicating commitment to security best practices. However, the website lacks explicit security headers and a published security.txt file, which are recommended for improved vulnerability disclosure and mitigation. No direct incident response emails are publicly listed, which could be enhanced to improve responsiveness. Overall, the security culture appears strong but could benefit from formalizing some web security practices.

Recommendations

  1. Implement and enforce security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options to mitigate common web attacks.
  2. Publish a security.txt file at the root domain to facilitate responsible vulnerability disclosure and improve transparency.
  3. Add a cookie consent banner and detailed cookie policy to comply with GDPR and other privacy regulations.
  4. Provide explicit incident response contact emails (e.g., security@ or abuse@) on the website to improve communication channels for security issues.
  5. Enhance accessibility features to meet WCAG standards, improving usability and compliance.

Technical notes

Notes

The website leverages a modern technology stack centered on Webflow CMS, Google Fonts, and jQuery, with integration of blockchain data via The Graph API and cross-chain token transfer support through Chainlink CCIP. Hosting is via AWS Cloudfront CDN, providing reliable content delivery. Performance is moderate with good mobile optimization and basic accessibility features. SEO is supported by proper meta tags and Open Graph data. The site uses rich multimedia content including background videos and interactive elements. Technical risks are minimal but could be reduced by updating security headers and improving privacy compliance mechanisms.
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.
