Risk levelLow

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

Melissa.com.br is the official online retail store for the Melissa footwear brand in Brazil, offering a variety of products including sneakers, sandals, and platforms. The website targets general consumers interested in fashion footwear and operates as a large-scale e-commerce platform. The site employs modern web technologies and analytics tools such as Segment Analytics, Microsoft Clarity, and Google Tag Manager, indicating a mature digital infrastructure. Hosting and DNS services are provided via Cloudflare, ensuring reliable performance and security. Security measures include HTTPS and Google reCAPTCHA Enterprise, but the absence of explicit security headers and published security policies suggests room for improvement in security posture. Privacy and cookie policies are not explicitly found, which may impact compliance with data protection regulations. Overall, the website is professionally designed, mobile-optimized, and provides a good user experience, but lacks some transparency in privacy and security documentation.

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. 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

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, Twitter, YouTube, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

  2. 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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Melissa operates in the retail sector focusing on footwear, positioning itself as a prominent brand in Brazil's fashion market. The business model is direct-to-consumer e-commerce, leveraging online sales channels to reach customers. The website's use of advanced analytics and tracking tools supports data-driven marketing and customer engagement strategies. The lack of visible contact information and corporate details on the site limits direct customer support insights. No evidence of partnerships or subsidiaries was found in the provided data. The brand maintains consistent branding and a professional online presence, supporting its market position as a leading footwear retailer in Brazil.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and integration of Google reCAPTCHA Enterprise to mitigate automated abuse. However, the absence of common security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces defense-in-depth. No vulnerability disclosure or incident response information is published, which may hinder transparency and responsiveness to security incidents. Privacy compliance indicators are weak due to missing privacy and cookie policies. No exposed sensitive data or vulnerable libraries were detected in the provided content. Overall, the security posture is adequate but could be enhanced by adopting best practices and publishing relevant policies.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies with clear consent mechanisms to improve GDPR and data protection compliance.
  2. Add security headers such as CSP, HSTS, and X-Frame-Options to strengthen security posture against common web attacks.
  3. Publish a vulnerability disclosure policy and incident response contact information to enhance transparency and security culture.
  4. Include clear and accessible contact information including emails and phone numbers for customer and security inquiries.
  5. Conduct regular security audits and update third-party libraries to mitigate potential vulnerabilities and maintain compliance.

Technical notes

Notes

The website uses a modern JavaScript-based front-end framework, likely React, with module preloading for performance optimization. It integrates multiple analytics and tracking services including Segment, Microsoft Clarity, and Google Tag Manager, enabling detailed user behavior analysis. Hosting via Cloudflare provides DNS security and performance benefits. The site is mobile-optimized and uses custom fonts and icon sets for branding consistency. However, accessibility features appear basic and could be improved. SEO optimization is good with proper meta tags and viewport settings. Performance is moderate, with potential for improvement through further optimization of assets and scripts.
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.
