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

6 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, LinkedIn, YouTube, 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

Mercado Pago leverages its parent company Mercado Libre's market dominance to offer integrated financial services that cater to both consumers and merchants. Its business model focuses on digital payments, credit products, and financial management tools, targeting a broad audience from individual users seeking digital accounts and credit cards to businesses requiring payment processing and sales facilitation tools. Partnerships with entities like Grupo Bursátil Mexicano and Mercado Lending expand its product offerings into investments and credit. The platform's extensive use of tracking and marketing tools indicates a data-driven approach to customer engagement and growth. The company's large size and presence in Mexico position it as a major fintech player in the region.

Security posture

The website maintains a solid security posture with proper DNS configurations including SPF and a strict DMARC policy set to reject unauthorized emails, reducing phishing risks. SSL/TLS configurations support modern protocols without known vulnerabilities like Heartbleed or FREAK. However, the lack of HSTS and OCSP stapling reduces the effectiveness of HTTPS enforcement and revocation checking. The detected subdomain takeover vulnerability on blog.mercadopago.com.mx is a critical issue that could allow attackers to hijack the subdomain, potentially leading to phishing or malware distribution. No explicit security policy or incident response contacts were found, indicating room for improvement in transparency and readiness. Overall, the security score is good but could be enhanced by addressing these gaps.

Recommendations

  1. Optimize page load performance by reducing resource count and page size.
  2. Improve mobile optimization further to enhance user experience on smaller devices.
  3. Consolidate and audit third-party scripts to reduce potential security and privacy risks.
  4. Implement security best practices such as HSTS and OCSP stapling.
  5. Enhance transparency by publishing security and incident response policies.

Technical notes

Notes

The website is built using a modern React-based framework (Nordic Webkit) with a modular landing page architecture. It uses New Relic for performance and error monitoring, Hotjar for user behavior analytics, and integrates multiple marketing and tracking pixels including Facebook, TikTok, and Google Tag Manager. Hosting is on Amazon AWS with Route53 DNS and Cloudfront CDN. Performance metrics indicate a slow load time (~22 seconds) with a large page size (~1.6 MB) and many resources (358), suggesting optimization opportunities. Accessibility and SEO practices are good, with proper metadata and ARIA attributes. The site is optimized for desktop with good mobile support. Technical debt is moderate due to the large resource count and some missing security enhancements.
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.
