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

The website vincentgarreau.com serves as a professional portfolio for Vincent Garreau, a front-end developer and co-founder of Livestorm, a webinar software company. The site highlights his professional experience, projects, and links to his social media profiles. The business focus is on technology and software development, particularly in webinar solutions and data visualization. The site is small-scale, personal, and targeted at tech professionals and potential collaborators. Technically, the website is built with standard web technologies including HTML5, CSS, JavaScript, and jQuery, with additional use of particles.js for visual effects. It is hosted by OVH sas and uses HTTPS with a valid SSL certificate. Google Analytics and Google Tag Manager are implemented for analytics and tracking. The site is moderately optimized for mobile and performance but lacks advanced accessibility features and SEO optimizations. From a security perspective, the site benefits from HTTPS and domain registration protections but lacks DNSSEC and important security headers. There is no privacy policy, cookie policy, or terms of service, which impacts compliance with GDPR and other privacy regulations. No incident response or vulnerability disclosure information is provided, limiting transparency in security practices. Overall, the website is professional and trustworthy as a personal portfolio but requires improvements in privacy compliance and security best practices to enhance trust and regulatory adherence.

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.

  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

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

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 · found on this site
  • 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

Vincent Garreau operates in the technology sector with a focus on front-end development and webinar software through Livestorm. The business model is SaaS, targeting webinar users and tech professionals. The portfolio demonstrates a strong technical skill set and a network of partnerships with other tech companies. The site reflects a small business or individual professional with growth potential. The presence of Google Analytics and Tag Manager indicates an interest in user engagement metrics. The lack of formal privacy and security policies suggests an area for business process improvement. The company is positioned as an innovative player in webinar technology with a credible online presence.

Security posture

The website's security posture is moderate. HTTPS is properly implemented, and domain registration includes protections against unauthorized transfers or deletions. However, the absence of DNSSEC and security headers such as Content-Security-Policy or X-Frame-Options reduces resilience against certain attacks. No privacy or cookie policies are present, which is a compliance gap under GDPR. The lack of a security.txt or vulnerability disclosure channel limits the ability for external parties to report security issues. Overall, the site is secure enough for a portfolio but should enhance security controls and compliance documentation to reduce risk.

Recommendations

  1. Implement a comprehensive privacy policy and cookie policy with GDPR compliance details.
  2. Enable DNSSEC on the domain to improve DNS security.
  3. Add security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Create a security.txt file to facilitate vulnerability disclosure and incident reporting.
  5. Improve accessibility features and SEO optimizations to enhance user experience and discoverability.

Technical notes

Notes

The website uses a custom-built front-end with jQuery and particles.js for interactive visual effects. It is hosted on OVH sas, a reputable hosting provider. The site loads external scripts asynchronously, including Google Analytics and Tag Manager, which supports performance. Mobile optimization is good but could be improved with enhanced accessibility. No CMS is detected, indicating a lightweight and controlled environment. The absence of DNSSEC and security headers represents technical debt in security. Overall, the technical infrastructure is solid for a personal portfolio but could benefit from modernization and security enhancements.
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.
