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

Melhor Envio is a leading Brazilian platform specializing in freight intermediation, offering users the ability to simultaneously compare shipping costs across multiple carriers and generate shipping labels with automatic tracking. The company targets both individuals and businesses seeking efficient freight management solutions. Their market position is strong within the transportation sector, supported by a comprehensive digital platform and active social media presence. Technically, the website employs a modern JavaScript-based stack with integrations including Google Tag Manager, ActiveCampaign, Datadog, and various marketing and analytics tools. Hosting is inferred to be on Amazon AWS infrastructure, with DNS managed via AWS Route53. The site shows good mobile optimization and SEO practices, although accessibility is basic. From a security perspective, the site implements several best practices such as Content Security Policy, HSTS with subdomain inclusion, CSRF tokens, and secure cookie flags. However, a critical issue is the invalid or missing SSL certificate and lack of TLS protocol support, which severely impacts secure communications. No explicit privacy policy, terms of service, or vulnerability disclosure documents were found, indicating gaps in compliance and transparency. Overall, Melhor Envio demonstrates a mature business and technical presence but requires urgent improvements in SSL/TLS configuration and formalization of privacy and security policies to enhance trust and compliance.

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

5 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  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

    • 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

    • High

      Third-party services without privacy policy

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

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

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

Melhor Envio operates as a platform in the transportation sector, focusing on freight cost comparison and shipping label generation. Their competitive advantage lies in aggregating multiple carriers for simultaneous quotation and providing automated tracking, appealing to a broad audience from individual shippers to businesses. The business model is platform-based, likely generating revenue through partnerships or service fees. The company shows strong digital marketing integration and a robust partner ecosystem. Growth indicators include active use of advanced analytics and marketing tools. Strategic observations suggest a focus on expanding platform capabilities and improving security and compliance to maintain market leadership.

Security posture

The current security posture of Melhor Envio is moderate with several strengths such as implementation of security headers (CSP, HSTS, XSS protection), CSRF tokens, and secure cookie attributes. However, the invalid SSL certificate and absence of TLS protocols represent critical vulnerabilities that expose users to potential man-in-the-middle attacks and data interception. The lack of a published privacy policy, terms of service, and vulnerability disclosure policy indicates compliance gaps, particularly with GDPR and other data protection regulations. Incident response readiness and security culture indicators are not evident from the data. Overall, the security maturity is adequate but requires immediate remediation of SSL issues and formal policy publication.

Recommendations

  1. Renew and properly configure SSL/TLS certificates to enable secure HTTPS connections with TLS 1.2 or higher.
  2. Publish comprehensive privacy policy and terms of service documents accessible from the main website.
  3. Implement and publicize a vulnerability disclosure policy and security.txt file to improve transparency and security culture.
  4. Enable OCSP stapling and session resumption mechanisms to enhance SSL performance and security.
  5. Regularly audit third-party scripts and tracking tools to ensure privacy compliance and minimize user tracking.
Technical notes

Notes

The website is built on a modern JavaScript stack served by nginx on AWS infrastructure. It uses multiple third-party services for analytics, marketing, and user engagement, including Google Tag Manager, ActiveCampaign, Datadog, and various ad networks. Performance is moderate with good mobile optimization and SEO practices. However, the absence of a valid SSL certificate and TLS support is a significant technical risk. The DNS setup is robust with multiple AWS Route53 nameservers and SPF/DKIM records configured for email security. There is no detected CMS, indicating a custom or proprietary platform. Technical debt appears low but the SSL misconfiguration is a critical issue that could impact business operations and user trust.
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.
