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

4ED is a Brazilian design school offering a broad range of online and in-person courses across multiple design disciplines including graphic, UX/UI, marketing, architecture, and product design. Established in 2011 and based in Porto Alegre, it serves students, professionals, and corporate clients with a comprehensive educational portfolio. The website demonstrates a mature digital presence with extensive use of WordPress, WooCommerce, and Elementor, complemented by advanced marketing and analytics tools such as Google Analytics, Facebook Pixel, and Bing UET. However, the absence of a valid SSL certificate on the main domain represents a significant security risk that could undermine user trust and data protection efforts. While privacy and cookie policies are well implemented and GDPR compliant, there is no explicit security or incident response policy publicly available. Overall, 4ED maintains a strong market position in design education in Brazil but should prioritize improving its security posture to safeguard its digital assets and user data.

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

3 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 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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

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

4ED operates in the education sector, focusing on design-related courses for a diverse audience including beginners, students, professionals, and enterprises. Its business model revolves around delivering educational content both online and in physical locations, with additional services like private lessons and mentoring. The company leverages a robust partnership ecosystem including social media platforms and marketing tools to enhance its reach and engagement. The presence of structured data and comprehensive content indicates a strategic approach to SEO and user experience. Growth indicators include a wide course catalog and active marketing campaigns. The company is medium-sized with 51-200 employees and holds a recognized legal and tax identity in Brazil.

Security posture

The current security posture of 4ED's website is moderate but with critical gaps. The lack of a valid SSL certificate and absence of modern TLS protocols expose the site to potential interception and data compromise. No security headers are detected, and DNSSEC is not enabled, which reduces DNS security. The site employs standard privacy and cookie consent mechanisms compliant with GDPR, indicating awareness of data protection requirements. However, no incident response or vulnerability disclosure policies are found, which could delay response to security incidents. The use of multiple third-party marketing and analytics tools increases the attack surface and necessitates rigorous monitoring and control. Overall, the security maturity is basic with urgent need for improvements in encryption and security policy transparency.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate supporting TLS 1.2 or 1.3 to secure all web traffic.
  2. Implement HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Enable DNSSEC and configure CAA records to enhance domain name system security.
  4. Publish a clear security policy and incident response plan accessible to users and stakeholders.
  5. Regularly audit and update all plugins, themes, and third-party integrations to mitigate vulnerabilities.

Technical notes

Notes

The website is built on WordPress CMS with extensive use of Elementor for page building and WooCommerce for e-commerce capabilities. It integrates multiple YITH plugins for booking, color labels, and dynamic pricing, indicating a complex e-commerce and course management system. Performance is currently slow with a high load time and many resources loaded, suggesting optimization opportunities. Mobile optimization and accessibility are good, supported by responsive design and ARIA attributes. SEO is well addressed with structured data (JSON-LD), Open Graph tags, and meta descriptions. Hosting is provided by Cloudez with multiple nameservers but lacks DNSSEC. The tech stack is modern but requires security enhancements and performance tuning to reduce technical debt and improve user experience.
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.
