Risk levelMedium

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

GBM is a leading Mexican financial services company offering a broad range of investment products, trading platforms, and advisory services to both individual and institutional clients. The company positions itself as a comprehensive investment ecosystem with over 6,000 financial instruments and a strong advisory network. Their website reflects a mature digital presence with extensive content, multiple service tiers, and integrated marketing and analytics tools. However, the site suffers from critical security shortcomings, notably the lack of a valid SSL certificate and absence of modern TLS protocols, which undermines user trust and data security. While privacy and cookie policies are present, explicit security policies and incident response information are not found, indicating potential compliance gaps. Overall, GBM demonstrates strong market positioning and digital maturity but requires urgent security improvements to safeguard client data and maintain regulatory 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

7 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 X-Frame-Options header

      Prevents clickjacking attacks

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

    • 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 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

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

GBM operates in the finance sector, targeting Mexican investors with a diversified product portfolio including investment accounts, trading in stocks, ETFs, bonds, and currencies, as well as institutional services and asset management. Their business model combines digital platforms with expert advisory services, catering to different customer segments through tiered service levels (Plus, Personal, Premium, Private). The company leverages partnerships for authentication, trading, and fund management. Their content strategy includes educational media and market insights, enhancing customer engagement. GBM's market position is strong in Mexico, supported by regulatory compliance and a large advisor network. Growth indicators include active marketing, extensive analytics, and a mobile app presence. Strategic partnerships and a robust digital infrastructure support their competitive advantage.

Security posture

The current security posture of GBM's website is weak due to the absence of a valid SSL certificate and lack of support for modern TLS protocols, exposing users to potential data interception risks. Although SPF and DMARC DNS records are properly configured to protect email integrity, the website lacks essential security headers and mechanisms such as HSTS, OCSP stapling, and session resumption. No public security policy or incident response information is available, which may hinder transparency and timely handling of security incidents. The extensive use of third-party tracking and marketing pixels increases the attack surface and raises privacy concerns. Overall, GBM needs to prioritize securing its web infrastructure and enhancing compliance with data protection regulations to mitigate risks and build user trust.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate immediately to secure all HTTPS traffic.
  2. Enable TLS 1.2 or TLS 1.3 protocols and disable outdated SSL/TLS versions to improve encryption strength.
  3. Implement HTTP Strict Transport Security (HSTS) with includeSubDomains and preload directives to enforce secure connections.
  4. Enable OCSP stapling and session resumption to enhance SSL performance and security.
  5. Publish a security.txt file and a clear vulnerability disclosure policy to facilitate responsible reporting.
  6. Add security-related HTTP headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  7. Review and minimize third-party tracking scripts to reduce privacy risks and improve compliance.
Technical notes

Notes

GBM's website is built on WordPress CMS with a modern front-end using jQuery and Slick Carousel for UI components. It integrates multiple marketing and analytics tools including Google Tag Manager, Facebook Pixel, TikTok Pixel, and Bing Ads. Hosting is provided via Amazon AWS DNS infrastructure. Despite a rich content and service offering, the site suffers from slow load times and a large page size, indicating potential optimization opportunities. Mobile optimization is good, but accessibility is basic. SEO is well implemented with comprehensive metadata and structured data. Technical debt is evident in the lack of SSL and outdated security protocols, which pose operational risks. Modernizing the security infrastructure and optimizing performance would significantly enhance the platform's reliability and user experience.
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.
