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

UpSeller is a SaaS company offering a free omni-channel ERP platform tailored for e-commerce sellers primarily in Latin America. The platform integrates with multiple major marketplaces such as Shopee, Mercado Libre, Amazon, and TikTok Shop, providing comprehensive tools for product management, order processing, inventory control, marketing, and analytics. The website is professionally designed, multilingual, and features strong user testimonials and official marketplace certifications, positioning UpSeller as a credible and established player in the e-commerce SaaS market. Technically, the website leverages modern JavaScript frameworks including Vue.js and integrates multiple analytics and tracking services such as Google Analytics, Microsoft Clarity, TikTok Pixel, and Facebook Pixel. The site is mobile-optimized and performs moderately well, though some improvements in security headers and cookie consent mechanisms are recommended. The absence of WHOIS registration data raises some concerns about domain transparency, but the overall digital maturity and business presence mitigate this risk. From a security perspective, the website uses HTTPS and modern frameworks but lacks explicit security headers and visible incident response contacts. There is no published vulnerability disclosure or security.txt file. Privacy compliance is partially addressed with a privacy policy and terms of service, but cookie consent is missing despite extensive tracking. Overall, the security posture is good but could be enhanced with additional transparency and controls. The overall risk assessment indicates a trustworthy and professional business with minor gaps in domain registration transparency and privacy compliance. Strategic recommendations include improving security headers, adding cookie consent, publishing security policies, and enhancing contact transparency to strengthen 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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

  3. 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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

UpSeller targets e-commerce sellers in Latin America, offering a SaaS ERP solution that centralizes multi-marketplace management. Its competitive advantage lies in free access, extensive marketplace integrations, and automation features that reduce operational complexity. Revenue likely derives from premium services or value-added features beyond the free tier. The platform supports multiple languages and marketplaces, indicating a broad regional focus. Partnerships with major marketplaces and certifications enhance credibility. Growth indicators include 200,000+ managed stores and 100 million+ monthly orders processed. The company maintains an active social media presence and user engagement through testimonials. Strategic observations suggest a focus on scalability, automation, and regional market dominance in Latin American e-commerce ERP solutions.

Security posture

The security maturity level is moderate to good. HTTPS is enforced, and no sensitive data is exposed in the HTML. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options is a gap. No explicit incident response or security contact information is published, limiting transparency. The lack of a vulnerability disclosure or security.txt file reduces the ability for external security researchers to report issues responsibly. Privacy compliance is partial; a privacy policy exists and appears comprehensive, but cookie consent mechanisms are missing despite extensive tracking. The use of multiple third-party analytics and tracking pixels increases the attack surface and privacy risk. Overall, the platform demonstrates a reasonable security posture but should enhance transparency, controls, and compliance to reduce risk and improve trust.

Recommendations

  1. Implement and enforce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Add a cookie consent banner/mechanism to comply with GDPR and other privacy regulations given the use of multiple tracking scripts.
  3. Publish a vulnerability disclosure policy or security.txt file to facilitate responsible security reporting and improve transparency.
  4. Provide clear security and incident response contact information on the website to enhance trust and readiness.
  5. Improve domain registration transparency by ensuring WHOIS data is complete and accurate or provide justification for privacy protection.

Technical notes

Notes

The website is built on a modern Vue.js framework with up-to-date versions of Vue Router and Vue I18n, supporting multilingual content. It uses CDN-hosted static assets and integrates multiple analytics and marketing pixels, indicating a mature digital marketing strategy. The site is mobile-optimized with responsive design and good SEO metadata including Open Graph tags. Performance is moderate, with asynchronous loading of scripts and prefetching of fonts and images. No CMS is detected, suggesting a custom or headless architecture. Hosting provider details are not explicit. Technical risks include missing security headers and lack of cookie consent, which could impact compliance and security posture. Opportunities exist to improve accessibility and security best practices without major architectural changes.
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.
