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.

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

MEO holds a strong market position in Portugal's telecommunications sector, supported by its parent company Altice Portugal. The business model integrates telecommunications, energy supply, and health services, with revenue streams from service subscriptions, device sales, and energy products. The company maintains a comprehensive partnership ecosystem including energy and retail domains. The website's content and navigation are tailored to a broad audience, emphasizing digital sales channels and customer self-service. Growth indicators include adoption of 5G technology and expansion into energy and health sectors. Strategic observations highlight the importance of maintaining compliance and enhancing security transparency to sustain customer trust.

Security posture

The website demonstrates a solid security foundation with HTTPS, cookie consent mechanisms, and use of reputable third-party analytics and marketing tools. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of a published security policy, incident response contacts, and vulnerability disclosure program indicates room for improvement in transparency and readiness. Compliance with GDPR is evident through privacy and cookie policies. The security score is high but could be enhanced by publishing explicit security governance documents and establishing clear channels for security incident reporting.

Recommendations

  1. Publish a dedicated security policy page detailing security practices and commitments.
  2. Establish and publicize an incident response contact email or portal (e.g., security@meo.pt).
  3. Implement and publish a vulnerability disclosure policy and security.txt file.
  4. Regularly review and audit third-party scripts to mitigate supply chain risks.
  5. Enhance user trust by providing more visible contact information and transparency on data protection.

Technical notes

Notes

The website is built on Microsoft SharePoint 2016, utilizing Bootstrap for responsive design and jQuery for client-side scripting. It integrates advanced marketing and analytics tools such as Google Tag Manager, Quantcast, InMobi, and Visual Website Optimizer, indicating a mature digital marketing strategy. Performance is moderate with preloading of fonts and deferred script loading. Accessibility and SEO optimizations are well implemented, including meta tags, Open Graph, and structured JSON-LD data. The technical infrastructure supports a large enterprise with multi-language support via Weglot. Opportunities exist to modernize some legacy SharePoint components and enhance security headers explicitly.
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.
