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 as an open source project with a strong community and ecosystem presence. Its business model revolves around providing free tooling with potential enterprise services and community engagement. The project hosts an annual conference (ViteConf) and maintains active social media and chat channels to foster collaboration. The website reflects a medium-sized technology entity focused on developer tools. The lack of explicit business contact information and privacy policies suggests a community-driven rather than traditional corporate structure. The site links to partner domains related to conferences and community resources, reinforcing its ecosystem approach.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and multiple security headers implemented, including HSTS, CSP, and X-Frame-Options. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a published security policy, incident response contacts, or vulnerability disclosure mechanisms indicates room for improvement in transparency and readiness. Privacy compliance is weak, lacking GDPR-related disclosures and cookie consent mechanisms. Overall, the security maturity is good but could benefit from formalized policies and contact channels.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy with GDPR compliance details.
  2. Add a dedicated security policy page including incident response procedures and contact information.
  3. Implement a vulnerability disclosure program and provide a security.txt file.
  4. Enhance accessibility features to meet higher standards and include accessibility statements.
  5. Provide clear business contact information to improve trust and compliance.

Technical notes

Notes

The website is built on a modern tech stack including VitePress for static site generation, Rollup for bundling, and uses native ESM modules for performance. It leverages Google Fonts and Algolia for search functionality, and Fathom Analytics for privacy-focused analytics. The site is fast loading, mobile optimized, and well structured with semantic HTML and meta tags for SEO. No technical debt or deprecated technologies were observed. The use of SVG graphics and interactive elements enhances user experience. Hosting provider details are not explicit but the site uses CDN resources for fonts and analytics. Overall, the technical implementation is robust and modern.
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.
