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

Vite.dev is the official website for Vite, a next-generation frontend build tool designed to provide blazing fast development experience for web applications. The site serves primarily as a documentation and marketing platform targeting web developers and frontend engineers. It highlights Vite's key features such as instant server start, lightning fast hot module replacement, rich feature support for TypeScript, JSX, CSS, and optimized builds using Rollup. The website is well-designed, mobile-optimized, and uses modern web technologies including VitePress for content management. Social media and community engagement channels like Discord, GitHub, and Bluesky are prominently linked, reinforcing its active open source community presence. However, the site lacks explicit privacy and cookie policies, which is a minor compliance gap.

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

9 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  2. 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';…

  3. 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

Vite operates in the technology sector, focusing on developer tools and frontend build systems. Its business model revolves around open source software with community-driven development and ecosystem growth. The website positions Vite as a leading modern build tool with strong technical advantages such as native ESM support and flexible plugin architecture. The presence of ViteConf events and extensive documentation indicates a mature ecosystem. The company behind Vite appears to be a medium-sized entity with a strong focus on developer experience and community engagement. No direct commercial contact information or business registration details are provided on the site.

Security posture

The website enforces HTTPS and uses modern security best practices, though explicit security headers are not detected in the provided data. No sensitive data exposure or vulnerable libraries were identified in the HTML content. The absence of a published security policy or incident response information suggests room for improvement in transparency and readiness. Analytics usage is minimal and privacy-respecting (Fathom Analytics). Overall, the security posture is good but could be enhanced by adding security headers, publishing security policies, and providing clear incident response contacts.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy with GDPR compliance details.
  2. Implement and document a security policy and incident response plan accessible on the website.
  3. Add security headers such as Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options.
  4. Provide clear contact information for security incidents (e.g., security@vite.dev or abuse@vite.dev).
  5. Enhance transparency by including business registration and data protection officer contact details if applicable.

Technical notes

Notes

The website is built using modern frontend technologies including VitePress, leveraging native ES modules and Rollup for optimized builds. It uses Google Fonts and Algolia for search functionality, and Fathom Analytics for privacy-conscious tracking. The site is fast, mobile-optimized, and accessible with good SEO metadata including Open Graph and Twitter cards. No CMS other than VitePress is detected. Hosting provider details are not explicit but the site uses HTTPS with a valid certificate. The technical implementation reflects a modern, well-maintained web presence with minimal technical debt.
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.
