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

Vincent Garreau's website serves as a professional portfolio highlighting his role as a front-end developer and co-founder of Livestorm, a webinar software company. The site showcases his work history, projects, and links to his social media profiles, targeting web developers and tech professionals interested in webinar solutions and data visualization. The business model centers on SaaS webinar software with a niche market position in providing smarter webinar experiences. Technically, the website employs standard web technologies including HTML5, CSS, JavaScript, and jQuery, supplemented by the particles.js library for visual effects. It uses asynchronous loading for Google Analytics and Google Tag Manager, indicating a moderate level of digital maturity. Hosting is provided by OVH sas, a reputable provider, though DNSSEC is not enabled. The site is mobile optimized with good SEO practices but lacks advanced accessibility features. From a security perspective, the site uses HTTPS but lacks visible security headers and formal security policies such as privacy, cookie, or incident response disclosures. No forms or sensitive data collection points are present, reducing immediate risk. However, the absence of privacy and cookie policies and lack of GDPR compliance indicators represent compliance gaps. The WHOIS data is consistent and trustworthy, with domain age aligning well with the business timeline. Overall, the website is professional and trustworthy but would benefit from enhanced privacy and security disclosures to improve compliance and user trust. Strategic improvements in security headers, policy transparency, and vulnerability disclosure would strengthen its security posture and regulatory alignment.

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. 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 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

Livestorm operates in the technology sector, focusing on webinar software as a SaaS offering. The company targets professionals and businesses seeking better webinar solutions. Competitive advantages include co-founder expertise in front-end development and a portfolio demonstrating technical skills and innovative projects like particles.js. Revenue streams likely derive from subscription-based webinar services. The partnership ecosystem includes links to related projects and professional networks such as LinkedIn and Twitter. Growth indicators include ongoing activity since 2010 and continuous involvement in technology projects. The business model is lean and focused on software development with a strong personal brand presence.

Security posture

The website demonstrates a basic security maturity level with HTTPS enabled and no exposed sensitive data. However, it lacks critical security headers and formal security policies, which are essential for protecting users and ensuring compliance with regulations like GDPR. There is no published incident response plan or vulnerability disclosure mechanism, which limits transparency and preparedness. The use of third-party analytics introduces moderate user tracking without clear privacy controls. Overall, the security posture is functional but requires enhancements to meet best practices and regulatory expectations.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie policy with explicit consent mechanisms to improve GDPR compliance.
  2. Enable DNSSEC for the domain to enhance DNS security and prevent spoofing.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  4. Establish and publish an incident response policy and vulnerability disclosure process to improve transparency and security readiness.
  5. Enhance accessibility features and conduct regular security audits to maintain a strong security culture and user trust.

Technical notes

Notes

The website is built on a solid technical foundation using HTML5, CSS, and JavaScript with jQuery and particles.js for interactive effects. It employs asynchronous loading of analytics scripts to optimize performance. Hosting is via OVH sas, a reputable provider, but DNSSEC is not enabled, representing a potential security gap. The site is mobile optimized with good SEO metadata but lacks advanced accessibility features. No CMS is detected, indicating a custom or static site approach. Performance is moderate with room for improvement in security headers and privacy compliance. Technical debt appears low, but modernization opportunities include enhanced security configurations and privacy controls.
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.
