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

99Webinar is a Brazilian SaaS platform specializing in webinar hosting and live streaming services, targeting Portuguese-speaking digital marketers and businesses. The platform emphasizes ease of use, local language support, and affordability compared to foreign competitors. The website is professionally designed, mobile optimized, and integrates multiple marketing and analytics tools such as Google Analytics, Hotjar, and Taboola. The technical infrastructure leverages Bootstrap, jQuery, and Cloudflare DNS services, with a proprietary CMS from leadlovers. Security posture is adequate with HTTPS enforced and clientTransferProhibited domain status, but lacks advanced DNSSEC and security headers. Privacy compliance is basic with cookie consent and privacy policies present but no explicit GDPR certifications. Contact information is clearly provided, enhancing business credibility.

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

7 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

The company operates under the parent brand leadlovers, with a clear market positioning as a national alternative to expensive foreign webinar platforms. Its subscription-based model is complemented by educational content and customer support, targeting digital marketing professionals and businesses in Brazil. The presence of payment processing partnerships with Hotmart and support portals indicates a mature ecosystem. Social media presence across major platforms supports brand engagement. The domain age and registration details align with the business history, supporting legitimacy. The company appears medium-sized with consistent branding and a focus on quality content delivery.

Security posture

The website enforces HTTPS and uses Cloudflare DNS with clientTransferProhibited status, which are positive security indicators. However, DNSSEC is not enabled, and no explicit security headers such as Content-Security-Policy or HSTS were detected in the provided data. The site uses multiple third-party scripts for analytics and marketing, which require regular auditing to mitigate vulnerabilities. Forms include input validation but lack visible advanced bot protection. No dedicated security policy or incident response information is published. Overall, the security posture is moderate but could be improved with enhanced DNS security and HTTP headers.

Recommendations

  1. Enable DNSSEC to protect against DNS spoofing and improve domain security.
  2. Implement security headers including Content-Security-Policy, X-Frame-Options, and HSTS to mitigate common web attacks.
  3. Conduct regular security audits of third-party scripts and dependencies to identify and remediate vulnerabilities.
  4. Add explicit security and incident response policies publicly accessible to improve transparency and trust.
  5. Enhance form security with CAPTCHA or other bot mitigation techniques to prevent automated abuse.

Technical notes

Notes

The website uses a modern tech stack including Bootstrap for responsive design, jQuery for DOM manipulation, and integrates multiple analytics and marketing tools such as Google Tag Manager, Hotjar, and Taboola. Hosting and DNS services are provided by Cloudflare, ensuring good performance and availability. The CMS appears to be a proprietary builder from leadlovers, which may limit flexibility but ensures integration with their ecosystem. Performance is moderate with good mobile optimization and basic accessibility features. SEO is supported by proper meta tags and Open Graph data. Technical debt is minimal but security enhancements are recommended to reduce risk.
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.
