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

Grupo TMM operates in the transportation and logistics sector, targeting customers primarily in Mexico and the USA. The website serves as a bilingual gateway offering language selection but lacks substantive content about the company's services or corporate information. The business model focuses on providing transport and logistics solutions, but the site does not elaborate on market position or detailed offerings. Technically, the website uses modern web fonts and icon libraries, with JavaScript and CSS assets loaded from local and CDN sources. However, there is no evidence of advanced frameworks or CMS platforms. The site appears to be moderately optimized for mobile devices but lacks comprehensive SEO and accessibility features. From a security perspective, the site lacks HTTPS information, security headers, and any visible privacy or cookie policies, indicating a low security maturity level. No contact or incident response information is provided, and no vulnerability disclosure mechanisms are evident. These gaps present risks related to compliance and user trust. Overall, the website is accessible but minimal, with significant room for improvement in content richness, security posture, and compliance. Strategic enhancements in these areas would improve user trust and regulatory adherence.

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

8 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • 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

  2. 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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. 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';…

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

Grupo TMM is positioned as a regional transportation and logistics provider with bilingual outreach to Mexico and USA markets. The company likely targets commercial clients requiring freight and logistics services. The business model is service-oriented, focusing on transport and logistics solutions. The website's minimal content limits insight into revenue streams or partnerships. No certifications or trust signals are presented, which could impact competitive positioning. The lack of detailed business information and contact data suggests a need for improved transparency and customer engagement.

Security posture

The current security posture is weak due to the absence of HTTPS confirmation, security headers, and privacy policies. No incident response or vulnerability disclosure information is available, indicating low preparedness for security incidents. The lack of contact information further complicates incident reporting and response. Compliance with GDPR or other data protection regulations is not demonstrated. These factors collectively suggest a low security maturity level with potential risks to data protection and user trust.

Recommendations

  1. Implement HTTPS with a valid SSL/TLS certificate to secure user connections.
  2. Publish comprehensive privacy and cookie policies to comply with GDPR and other regulations.
  3. Add clear contact information including emails and phone numbers for customer and security incident communication.
  4. Introduce security headers such as Content-Security-Policy and X-Frame-Options to enhance protection.
  5. Develop and publish a vulnerability disclosure policy and security.txt file to improve transparency and security culture.

Technical notes

Notes

The website uses standard web technologies including JavaScript, CSS, Google Fonts, and icon libraries. No advanced frameworks or CMS platforms are detected. Performance is moderate with assets loaded from CDNs, aiding speed. Mobile optimization is good given the viewport meta tag and responsive design elements. However, SEO and accessibility features are basic, and no structured data or meta tags beyond title and charset are present. The site would benefit from enhanced SEO metadata, accessibility improvements, and adoption of modern frameworks or CMS for scalability.
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.
