75/100

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

Neovim is an open source, hyperextensible Vim-based text editor designed for developers seeking a modern and extensible editing experience. It offers advanced features such as a first-class API, remote plugins, Lua scripting support, and built-in language server protocol integration. The project is well-positioned in the developer tools market as a popular alternative to Vim, supported by an active community and sponsors. Technically, the website is built with modern web technologies including Bootstrap and Algolia DocSearch, hosted via Cloudflare, and optimized for performance and accessibility. Security posture is solid with HTTPS enforced and domain transfer protections, though it lacks some security headers and formal security policies. Privacy compliance is weak due to absence of privacy and cookie policies. Overall, the website is professional, trustworthy, and content-rich, but could improve transparency and compliance documentation.

Scanned

3 of 7 checks could not complete. The site may be unreachable or blocking automated scans, so the results below cover only what could be checked. Try a rescan later.

NIS2 and GDPR posture

GDPR outside view
Not assessed

Both readouts depend on the site's pages, which could not be loaded in this scan.

Priority findings

1 finding rated critical or high. Fix these first.

  1. 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

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

  • Security headers: did not complete in this scan.
  • GDPR outside view: did not complete in this scan.
  • 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.

Dark web exposure

Add-on

Leaked records that mention neovim.io, from OffSeq Breach.

No leaked records found

Breach holds no records for neovim.io right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Neovim operates as a small, technology-focused open source project targeting developers and programmers. Its business model relies on community sponsorships and donations rather than direct sales. The project maintains a strong market position as a modern Vim alternative with a growing ecosystem of plugins and integrations. Partnerships with companies like Warp, Graphite, and CodeRabbit indicate a supportive ecosystem. The website content and structure reflect a mature project with clear branding and active development. Growth indicators include recent news updates and ongoing roadmap planning. The absence of direct contact information suggests a community-driven support model rather than traditional corporate customer service.

Security posture

The website demonstrates a good security baseline with HTTPS enabled and domain registration protections such as clientTransferProhibited status. However, it lacks DNSSEC, security headers (e.g., CSP, HSTS), and published security policies or vulnerability disclosure mechanisms. No contact channels for security incidents are provided. There is no evidence of exposed sensitive data or vulnerable libraries. The absence of a security.txt file and formal incident response information indicates room for improvement in security transparency and readiness. Overall, the security posture is adequate for an open source project website but could be enhanced to meet higher compliance and trust standards.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement and publish a comprehensive privacy policy and cookie consent mechanism to improve GDPR compliance.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to harden the website.
  4. Create and publish a security policy and vulnerability disclosure page including contact information for security incidents.
  5. Provide clear contact information or a contact form for general inquiries to improve user trust and support.

Technical notes

Notes

The website uses a modern and lightweight technology stack including HTML5, CSS with Bootstrap, JavaScript, and Algolia DocSearch for search functionality. It is hosted behind Cloudflare, providing CDN and security benefits. The site is mobile optimized and accessible with semantic HTML and ARIA labels. Performance is fast with minimal external dependencies. No CMS is detected, indicating a static or custom-built site. The site lacks analytics scripts beyond search, indicating minimal user tracking. Technical debt appears low with clean markup and up-to-date libraries. Opportunities exist to improve security headers and add structured data for enhanced SEO.
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.
