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

Correio Braziliense is a leading Brazilian media company specializing in news coverage for Brasília, the Distrito Federal, and broader national and international topics. The website serves a general audience with a comprehensive offering of news articles, analyses, and video content. It operates a business model based on advertising and subscription services, positioning itself as a major player in the regional media market. The company maintains a consistent brand presence and integrates well with social media platforms to extend its reach. Technically, the website employs a modern digital infrastructure leveraging Amazon AWS for hosting and DNS, and integrates advanced advertising technologies including Google Ad Manager, Amazon APS, Taboola, and Prebid.js for programmatic ad bidding. Analytics are extensively used via Google Analytics and Chartbeat, with tracking mechanisms that indicate a mature digital marketing strategy. The site is mobile optimized and demonstrates good SEO practices, although accessibility features are basic. From a security perspective, the site enforces HTTPS and uses asynchronous loading of scripts to reduce risk exposure. However, explicit security headers such as Content-Security-Policy and X-Frame-Options are not evident, and there is no published security policy or incident response contact information. No vulnerability disclosure or security.txt file is found, which could be improved to enhance transparency and trust. Overall, the website is professionally designed, content-rich, and trustworthy with a strong market position. The main risks relate to the absence of explicit security policies and vulnerability disclosure mechanisms. Strategic improvements in these areas would strengthen the security posture and compliance profile.

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 X-Frame-Options header

      Prevents clickjacking attacks

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

  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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, Twitter, YouTube, Amazon Ads, Google Ads

      What to do: Document all third-party data sharing in your privacy policy

  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

Correio Braziliense holds a prominent position as a regional news publisher in Brazil, focusing on Brasília and the Distrito Federal. Its competitive advantage lies in its established brand, comprehensive news coverage, and integration with multiple digital advertising and analytics platforms. The business model relies heavily on advertising revenue supplemented by subscription plans, as indicated by links to subscription services and advertising price tables. The target customer segments include general news consumers, local residents, and professionals interested in politics, economy, science, and culture. The company leverages partnerships with advertising networks and content recommendation platforms like Taboola to maximize monetization. Growth indicators include active social media presence and continuous content updates. The company operates a multi-channel content distribution strategy including blogs and video content, enhancing engagement and market reach.

Security posture

The website demonstrates a moderate to good security maturity level. HTTPS is enforced, ensuring encrypted communications. The use of Google Tag Manager and asynchronous script loading reduces some risks related to script injection. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options represents a gap in defense-in-depth. No security policy or incident response contact is published, limiting transparency and readiness for security incidents. There is no evidence of vulnerability disclosure or security.txt, which are best practices for mature security programs. No exposed sensitive data or vulnerable libraries were detected in the HTML content. Overall, the security posture is adequate for a media website but could be improved by adopting additional security headers, publishing security policies, and establishing clear incident response channels.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  2. Publish a dedicated security policy page detailing security practices and incident response procedures to enhance transparency and trust.
  3. Establish a vulnerability disclosure program and publish a security.txt file to facilitate responsible reporting of security issues.
  4. Review and audit third-party scripts and advertising technologies regularly to minimize risks from external dependencies.
  5. Enhance accessibility features to improve compliance with standards and broaden audience reach.

Technical notes

Notes

The website is hosted on Amazon AWS infrastructure, indicated by the use of AWS DNS servers. It employs a modern tech stack with extensive use of JavaScript libraries and advertising frameworks such as Google Tag Manager, Google Analytics, Chartbeat, Taboola, Amazon APS, and Prebid.js for programmatic advertising. The site uses responsive design techniques and preloading strategies for fonts, images, and CSS to optimize performance. DNS prefetch and preconnect hints are used to improve loading times. The site integrates multiple social media platforms and uses structured data (JSON-LD) for SEO enhancement. Performance is moderate, with room for improvement in accessibility and security header implementation. The technical setup reflects a mature digital publishing platform with advanced monetization and analytics capabilities.
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.
