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

Mercado Shops, part of the Mercado Livre ecosystem, is an e-commerce platform serving sellers in Brazil. The website announces the discontinuation of Mercado Shops by the end of 2025 and encourages sellers to transition to 'Minha página', a personalized online store within Mercado Livre. The platform is well integrated with Mercado Livre's marketplace and payment services, targeting sellers who want to maintain and grow their online presence. Technically, the site uses modern web technologies including React, New Relic monitoring, and Google Analytics, hosted on Amazon AWS with a valid SSL certificate and strong security headers. However, the absence of TLS 1.2 or 1.3 protocols is a notable gap. The site implements cookie consent and privacy policies compliant with local regulations but lacks explicit public security policies or incident response information. Overall, the business is positioned as a leading e-commerce enabler in Latin America with a strong digital presence and good security posture, though improvements in TLS configuration and transparency on security policies are recommended.

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, 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

The business operates in the e-commerce sector, providing online store solutions and marketplace access primarily in Brazil. It leverages the Mercado Livre ecosystem, the largest e-commerce platform in Latin America, to offer sellers tools to manage shops, migrate to new platforms, and integrate payment solutions via Mercado Pago. The company targets sellers transitioning from Mercado Shops to newer solutions, emphasizing ease of migration, brand personalization, and multi-channel sales. The platform's integration with partner solutions and marketing tools like Klaviyo and Emarsys indicates a mature marketing ecosystem. The business model is based on subscription fees for 'Minha página' and transaction fees from marketplace sales. The company maintains a consistent brand and provides comprehensive educational content to sellers, reinforcing its market leadership and customer engagement.

Security posture

The website demonstrates a good security posture with a valid SSL certificate issued by Amazon RSA 2048 M02, HSTS enabled with preload and includeSubDomains, and no detected vulnerabilities such as Heartbleed or POODLE. DNS records include SPF for email protection, though DNSSEC and CAA records are not configured, representing an area for improvement. The absence of TLS 1.2 or TLS 1.3 protocols is unusual and may indicate a misconfiguration or incomplete scan data, warranting further investigation. No public security policy or incident response contacts are disclosed, which could impact transparency and trust. Cookie consent mechanisms and privacy policies are implemented, supporting compliance with privacy regulations. Overall, the security maturity is good but could be enhanced by improving TLS support, DNS security, and public disclosure of security practices.

Recommendations

  1. Enable and enforce TLS 1.2 or TLS 1.3 protocols to ensure secure communications.
  2. Implement DNSSEC and CAA DNS records to strengthen DNS security and certificate issuance control.
  3. Publish a clear security policy and incident response plan with contact information to improve transparency.
  4. Optimize page load performance to reduce load time and improve user experience.
  5. Regularly review and update privacy and cookie consent mechanisms to maintain compliance with evolving regulations.
Technical notes

Notes

The website is built using modern JavaScript frameworks, likely React, with extensive use of New Relic for performance and error monitoring and Google Analytics for user tracking. It uses Amazon AWS infrastructure for hosting and SSL certificates. The site employs lazy loading for images and modern web fonts for consistent branding. Despite a large page size and slow load time, mobile optimization and accessibility are good. The technical stack is mature and well-integrated with Mercado Livre's ecosystem, but TLS protocol support appears lacking, which is a critical technical risk. The site uses multiple third-party marketing and tracking tools, indicating a sophisticated digital marketing approach. Overall, the technical infrastructure supports a large-scale e-commerce platform but requires TLS and performance improvements.
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.
