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

Farcaster is a decentralized social networking platform founded in 2021, targeting developers, artists, NFT collectors, and meme creators. It offers community engagement through its web platform and dedicated mobile applications for iOS and Android. The business positions itself as a niche player in the decentralized social network market, emphasizing community and technology innovation. The website is professionally designed with consistent branding and clear calls to action for sign-up and app downloads. Technically, the site leverages modern web technologies including React, ES modules, and Cloudflare infrastructure, ensuring good performance and mobile optimization. However, accessibility and SEO optimizations are basic and could be improved. Security posture is solid with HTTPS and domain transfer protections, but lacks DNSSEC and security headers, and does not publish a security policy or incident response contacts. Privacy compliance is partial with privacy and terms pages present but no cookie consent mechanism. Overall, the site is trustworthy and safe with no adult or questionable content detected.

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

6 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 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

  3. 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.

    • High

      SSL Certificate Expires Soon

      SSL certificate expires in 9 days

      What to do: Renew SSL certificate before expiration

      • NIS2 21(2)(h)
      • IR 2024/2690 9.2(c): Implementing Regulation (EU) 2024/2690, Annex point 9.2(c): Cryptography
      • NIST SC-17: NIST SP 800-53 Rev. 5 SC-17: Public Key Infrastructure Certificates

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

Farcaster operates in the technology sector focusing on decentralized social networking. Its business model revolves around community-driven social engagement with mobile app distribution through major app stores. The company is small-sized, US-based, and relatively young, founded in 2021. It leverages partnerships with app stores and uses Cloudflare for hosting and DNS services. The platform targets tech-savvy users interested in decentralized social media, NFTs, and creative communities. The presence of developer documentation indicates an ecosystem approach. The company maintains consistent branding and trust signals such as HTTPS and domain transfer locks. However, direct contact information and detailed business disclosures are limited on the website, which could be improved to enhance credibility.

Security posture

The website demonstrates a moderate to good security posture with mandatory HTTPS and domain transfer protection. However, it lacks DNSSEC, which would enhance DNS security. No security headers were detected in the HTML content, which are recommended to mitigate common web vulnerabilities. There is no published security policy or incident response contact information, which limits transparency and readiness perception. The site uses a third-party analytics script (pencil-novel) which may introduce privacy considerations. No vulnerabilities or exposed sensitive data were detected in the content. Overall, the security posture is adequate for a small technology platform but could be improved by implementing recommended headers, DNSSEC, and publishing security policies.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement standard security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Add a cookie consent mechanism to comply with privacy regulations and improve user trust.
  4. Publish a dedicated security policy and incident response contact information to enhance transparency and readiness.
  5. Review third-party analytics scripts for privacy compliance and consider minimizing tracking.

Technical notes

Notes

The website is built using modern web technologies including React and ES modules, with assets loaded via modulepreload for performance optimization. It uses Google Fonts and Cloudflare DNS and hosting services, indicating a robust infrastructure. The site is mobile optimized and uses CSS variables for theming. Performance is fast with good loading practices. However, accessibility features are basic and SEO optimization is minimal, relying mostly on meta description and title tags. There is no detected CMS, suggesting a custom or static site generation approach. The technical stack is modern and well-implemented but could benefit from enhanced accessibility and SEO improvements.
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.
