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

4 findings rated critical or high. Fix these first.

  1. 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

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  2. 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"

  3. 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

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

O Globo holds a prominent market position as a major news publisher in Brazil, targeting a broad general audience. Its business model centers on digital content delivery and advertising revenue. The site leverages partnerships with major ad networks and tracking services to optimize monetization. The parent company, Grupo Globo, provides strong brand recognition and operational support. The absence of direct contact information on the main page suggests centralized customer service likely handled at the parent level. The company benefits from a consistent brand and high content quality, supporting sustained audience trust and market leadership.

Security posture

The website employs HTTPS with good SSL configuration and uses multiple third-party scripts for analytics and advertising. While no critical vulnerabilities were detected, the absence of certain security headers like Content-Security-Policy and X-Frame-Options could be addressed to enhance protection against common web attacks. No exposed sensitive data or vulnerable libraries were identified. Privacy policies and cookie consent mechanisms indicate compliance with GDPR and related regulations. Incident response and vulnerability disclosure mechanisms were not found, which could be improved to strengthen security governance.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Establish and publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  3. Enhance accessibility features to improve compliance with standards and user experience for all audiences.
  4. Provide clear and accessible contact information for security incidents and general inquiries.
  5. Regularly audit third-party scripts and dependencies to mitigate risks from external libraries.

Technical notes

Notes

The website uses a modern tech stack including Google Tag Manager, Google Analytics, Facebook Pixel, and other marketing and analytics tools. It loads fonts from Google Fonts and uses lazy loading for images to optimize performance. The site is mobile optimized with responsive design elements. SEO is supported by proper meta tags and structured data in JSON-LD format. Hosting details are not explicitly found but the use of Globo's own CDN and infrastructure is implied. Performance is moderate with room for improvement in accessibility and security headers. Overall, the technical implementation supports a large-scale media operation effectively.
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.
