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

Nerd Fonts is an open source project focused on aggregating, patching, and distributing developer-targeted fonts enriched with a vast collection of iconic glyphs from popular icon fonts such as Font Awesome, Octicons, and Devicons. The project targets developers and programmers who want enhanced terminal and editor fonts with rich iconography. It enjoys a strong community presence on GitHub and Gitter, with frequent updates and a comprehensive font patcher tool. Technically, the website is well-structured, mobile-optimized, and uses modern web technologies including Google Fonts and analytics tools. Security posture is generally good with HTTPS enforced and no exposed sensitive data, but lacks explicit security headers and formal privacy or cookie policies. The absence of WHOIS data for the domain raises some concerns about domain registration legitimacy, though the active open source community and transparent project details mitigate this risk. Overall, the site is professional, trustworthy, and safe for general audiences.

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

Nerd Fonts operates as a small but important player in the developer tools ecosystem, providing a unique value proposition by combining multiple iconic font sets into patched fonts for programming use. Its open source business model relies on community contributions and GitHub distribution. The project is well-positioned in the niche of developer productivity and customization tools, with integrations and support from popular shell themes and terminal utilities. Revenue streams are not explicit but likely include donations and sponsorships. The project maintains partnerships with major icon font providers and leverages open source collaboration platforms. Growth indicators include active GitHub releases and community engagement. Strategic observations suggest focusing on formalizing privacy and security policies and improving domain registration transparency to enhance trust.

Security posture

The website demonstrates a moderate to good security maturity level. HTTPS is enforced, and no sensitive data or vulnerable libraries are exposed. However, the lack of explicit security headers such as Content-Security-Policy and X-Frame-Options is a gap. No contact information or incident response policies are published, limiting transparency in case of security incidents. There is no evidence of GDPR compliance or data protection officer contact, which may be relevant given the use of tracking analytics. The absence of a vulnerability disclosure policy or security.txt file reduces the ability for coordinated vulnerability reporting. Overall, the security posture is adequate for an informational open source project but could be improved with formal policies and headers.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie policy to improve privacy compliance and user trust.
  2. Add explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  3. Provide clear contact information including security incident response contacts and consider publishing a vulnerability disclosure policy or security.txt file.
  4. Verify and update domain WHOIS registration information to ensure transparency and legitimacy of domain ownership.
  5. Enhance user privacy by reviewing and possibly limiting tracking analytics or providing opt-out mechanisms.

Technical notes

Notes

The website is built with standard modern web technologies including HTML5, CSS, and JavaScript, and uses Google Fonts for typography. It integrates Google Analytics and Google Tag Manager for user tracking. The site is mobile responsive and well-structured with clear navigation and SEO meta tags. No CMS or hosting provider information is directly detectable. Performance appears fast with minimal external dependencies. The font patcher tool is implemented as a Python script distributed via GitHub. There is no evidence of technical debt or outdated libraries. Opportunities exist to improve security headers and formalize privacy and compliance documentation.
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.
