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

Mozilla Ventures is an impact venture fund affiliated with Mozilla Corporation, focusing on investing in early-stage startups that align with the values of the Mozilla Manifesto. The fund targets mission-driven founders developing trustworthy AI, healthy communities, and security & privacy technologies. The website presents a professional portfolio of investments and a blog featuring relevant industry news and updates. Technically, the site is built on WordPress with modern SEO practices and uses common libraries such as jQuery and Slick Carousel. Security posture is solid with HTTPS enforced, though some security headers and explicit policies are missing. Privacy compliance is supported by links to Mozilla's comprehensive privacy and cookie policies, though no explicit cookie consent mechanism is present. Overall, the site demonstrates good business credibility and technical maturity with room for security and privacy enhancements.

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

5 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 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

  3. 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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

Mozilla Ventures occupies a niche market position as an impact-focused venture capital fund leveraging the Mozilla brand's trust and values. Its business model centers on early-stage investments in technology startups that promote internet health, privacy, and trustworthy AI. The portfolio includes notable companies in AI and security sectors, indicating a strategic focus on emerging technologies. The fund targets founders, developers, and researchers aligned with Mozilla's mission, fostering a community outside traditional big tech and academia. The website's content and external links reflect active engagement with industry news and partnerships. While direct contact information is limited, the presence of social media channels and career links supports outreach and recruitment efforts.

Security posture

The website enforces HTTPS, ensuring encrypted communications. However, no explicit security headers such as Content Security Policy, HSTS, or X-Frame-Options were detected, which could enhance protection against common web attacks. There is no visible security policy or incident response information published, nor a vulnerability disclosure or security.txt file. No exposed sensitive data or vulnerable libraries were found in the HTML content. The absence of a cookie consent mechanism may pose compliance risks under GDPR. Overall, the security posture is moderate with good encryption but lacking in advanced header protections and published security governance documents.

Recommendations

  1. Implement and configure security headers including CSP, HSTS, and X-Frame-Options to strengthen web security.
  2. Publish a dedicated security policy and incident response page to improve transparency and readiness.
  3. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Introduce a cookie consent mechanism to comply with GDPR and enhance user privacy controls.
  5. Enhance accessibility features to improve inclusivity and compliance with standards.

Technical notes

Notes

The website is built on WordPress CMS with the Yoast SEO plugin, leveraging jQuery and Slick Carousel for interactive elements. The HTML is valid and includes comprehensive meta tags for SEO and social media sharing (Open Graph and Twitter Cards). Performance is moderate with optimized images and responsive design evident. Mobile optimization is good, and navigation is clear and consistent. No major technical debt or deprecated technologies were detected. Hosting provider details are not explicit, but the site uses HTTPS with a valid SSL certificate. Opportunities exist to improve accessibility and implement advanced security headers.
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.
