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

Simple Icons is an open source project founded in 2013 that provides a comprehensive library of 3354 SVG icons representing popular brands. It serves developers, designers, and digital content creators who require consistent and scalable brand icons for their projects. The project is community-driven, hosted on GitHub, and supported by donations via Open Collective, positioning it as a trusted resource in the design and development ecosystem. Technically, the website leverages modern web technologies including JavaScript and WebAssembly for performance, and is hosted with Cloudflare DNS services. The site is well optimized for mobile devices, loads quickly, and offers a clean user experience with clear navigation and search capabilities. However, DNSSEC is not enabled, and no advanced security headers are detected, indicating room for improvement in security hardening. From a security perspective, the site uses HTTPS with a valid SSL configuration and has domain transfer protections enabled. The domain is privacy protected, which is common for open source projects, and the domain age aligns with the project's history, supporting legitimacy. There are no visible vulnerabilities or exposed sensitive data, but the absence of explicit privacy and cookie policies and consent mechanisms is a compliance gap. Overall, Simple Icons presents a low-risk profile with a strong reputation in its niche. Strategic recommendations include enabling DNSSEC, implementing comprehensive privacy and cookie policies with consent mechanisms, and adding security headers to enhance protection. These steps will improve compliance posture and user trust while maintaining the project's open source ethos.

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 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

Simple Icons occupies a niche in the technology sector as a provider of free, open source SVG brand icons. Its business model is community-supported, relying on contributions and donations rather than direct revenue. The project targets developers and designers globally, offering a valuable resource that integrates into various platforms and tools. Its partnerships include GitHub for code hosting and Open Collective for funding. The project demonstrates steady growth and active maintenance, with a broad ecosystem of third-party extensions and integrations enhancing its reach and utility.

Security posture

The security posture of Simple Icons is moderate to good. The site enforces HTTPS and has domain transfer protections, reducing risks of domain hijacking. However, the lack of DNSSEC and security headers such as Content-Security-Policy or X-Frame-Options limits its defense-in-depth. No incident response or security policy pages are published, which could hinder coordinated vulnerability management. The absence of privacy and cookie consent mechanisms also poses compliance risks under GDPR. Overall, the site is secure for its purpose but would benefit from enhanced security controls and documented policies.

Recommendations

  1. Enable DNSSEC to protect DNS integrity and prevent spoofing.
  2. Publish comprehensive privacy and cookie policies with explicit user consent mechanisms.
  3. Implement security headers like Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Establish and publish a vulnerability disclosure policy or security.txt file.
  5. Add contact information for security incidents and data protection officer if applicable.

Technical notes

Notes

The website uses a modern tech stack including JavaScript modules and WebAssembly for efficient icon rendering. Hosting is via Cloudflare DNS, providing reliable and fast content delivery. The site is mobile optimized and accessible, with semantic HTML and ARIA roles. Performance is fast with minimal external dependencies aside from Carbon Ads for monetization. No CMS is detected, indicating a custom or static site architecture. The site lacks some advanced SEO and security features but overall demonstrates good technical maturity with opportunities for incremental 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.
