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

Filfox.info is a specialized blockchain explorer and data service platform focused on the Filecoin network. It offers comprehensive mining rankings, blockchain data queries, visualization charts, and FEVM contract metrics, targeting Filecoin miners, developers, and investors. The platform is positioned as a key data provider within the Filecoin ecosystem, leveraging modern web technologies and providing API access for developers. The website is professionally designed, mobile optimized, and provides real-time blockchain data, enhancing user experience and engagement. Technically, the site is built on the Nuxt.js framework with Element UI components, hosted on Alibaba Cloud, and uses modern JavaScript technologies. Performance is moderate with good SEO and mobile responsiveness. However, accessibility features are basic and could be improved. Security posture is adequate with HTTPS enforced, but lacks advanced security headers and DNSSEC, which are recommended for enhanced protection. From a security and compliance perspective, the site lacks visible privacy, cookie, and security policies, which are critical for GDPR and other regulatory compliance. Contact information is limited to an email address, and no incident response or vulnerability disclosure information is published. No WAF or blocking mechanisms are detected, and no suspicious or malicious content is found. Overall, the platform appears legitimate and trustworthy but would benefit from enhanced privacy and security transparency. The overall risk is moderate with recommendations to implement privacy and cookie policies, enable DNSSEC, add security headers, and publish incident response and vulnerability disclosure information to improve 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

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 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

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

Filfox.info operates in the blockchain technology sector, providing essential data services for the Filecoin ecosystem. Its competitive advantage lies in its comprehensive and real-time blockchain data, mining statistics, and FEVM contract analytics. The business model revolves around offering free and API-accessible blockchain explorer services, targeting miners, developers, and investors. The platform shows growth potential given the expanding Filecoin network and increasing demand for blockchain transparency. Partnerships with Filecoin-related projects and integration with decentralized naming services (FNS) indicate a strong ecosystem presence. The company is based in China, founded in 2020, and maintains a medium-sized operational scale. Strategic observations suggest focusing on compliance and security enhancements to solidify market position and user trust.

Security posture

The security maturity level of Filfox.info is moderate. The site enforces HTTPS, ensuring encrypted communications, but lacks several recommended security headers such as Content-Security-Policy and X-Frame-Options, which could mitigate common web attacks. DNSSEC is not enabled, representing a potential risk for DNS spoofing. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of published security policies, incident response plans, and vulnerability disclosure mechanisms indicates gaps in security governance and transparency. Compliance with GDPR and other data protection regulations is uncertain due to missing privacy and cookie policies. The platform should prioritize implementing these policies and security best practices to enhance its security posture and regulatory compliance.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies with user consent mechanisms to ensure GDPR compliance.
  2. Enable DNSSEC for the domain to protect against DNS spoofing and improve domain security.
  3. Add essential security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance web security.
  4. Publish a security policy and incident response plan, including contact channels for security issues (e.g., security@ or abuse@ emails).
  5. Conduct regular security audits and vulnerability assessments to identify and remediate potential risks proactively.

Technical notes

Notes

Filfox.info is built using modern web technologies including Nuxt.js (Vue.js framework) and Element UI components, providing a responsive and interactive user interface. The site is hosted on Alibaba Cloud, a reputable cloud provider, ensuring reliable infrastructure. Performance is moderate with preloaded scripts and stylesheets optimizing load times. The site is mobile optimized with adaptive layouts and accessible navigation menus. SEO is well addressed with appropriate meta tags and structured content. However, accessibility features are basic and could be improved to meet higher standards. The absence of a CMS suggests a custom-built platform tailored for blockchain data services. Technical risks include lack of DNSSEC and missing security headers, which should be addressed to reduce attack surface and improve resilience.
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.
