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

The Portal da Transparência do Governo Federal is an official Brazilian federal government transparency portal managed by the Controladoria-Geral da União. It provides comprehensive public access to government spending data, contracts, social benefits, employee remuneration, bidding processes, sanctions, and other fiscal information. The portal targets Brazilian citizens and stakeholders interested in government transparency and social control. It operates as an enterprise-level government service, offering open data downloads and APIs to facilitate public analysis and oversight. Technically, the website employs a modern technology stack including jQuery, Bootstrap, Google Tag Manager, and AWS hosting infrastructure. It uses the govbr design system ensuring consistent branding and accessibility. The site is mobile optimized and includes accessibility features, with good SEO and performance characteristics. The use of AWS WAF scripts indicates a security-aware hosting environment. From a security perspective, the portal enforces HTTPS with excellent SSL configuration and manages cookie consent in compliance with LGPD (Brazilian data protection law). While explicit security headers are not fully visible in the HTML, best practices are implied. No vulnerabilities or exposed sensitive data were detected. However, the site lacks a published security policy, incident response contacts, and a security.txt file, which are recommended for enhanced transparency and vulnerability management. Overall, the portal demonstrates a high level of professionalism, trustworthiness, and compliance with privacy regulations. It serves as a critical tool for public accountability in Brazil. Strategic recommendations include formalizing security policies, publishing incident response contacts, enhancing security headers, and expanding transparency on data retention and privacy practices.

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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, Twitter, LinkedIn, Cloudflare, Google APIs

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

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

The portal holds a strong market position as the official transparency platform for the Brazilian federal government, operated by the Controladoria-Geral da União. It leverages open data principles to empower citizens and civil society with detailed fiscal information. The business model is government-funded and focused on transparency and social control rather than revenue generation. Key services include detailed queries on public benefits, contracts, expenses, transfers, and government employees. The portal integrates with other government data sources and social media channels, enhancing its ecosystem. Growth indicators include continuous updates, new data APIs, and expanded data categories. Partnerships with other government entities and open data initiatives strengthen its strategic footprint.

Security posture

The portal exhibits a mature security posture with enforced HTTPS, cookie consent aligned with LGPD, and hosting on AWS with WAF protections. No critical vulnerabilities or security misconfigurations were detected in the analyzed content. The absence of explicit security policies and incident response contacts represents a compliance gap. The use of multiple Google Tag Manager containers and analytics scripts requires ongoing monitoring to prevent privacy leaks. Overall, the portal balances accessibility and security well but should formalize its security governance and vulnerability disclosure mechanisms to meet best practices and regulatory expectations.

Recommendations

  1. Publish a dedicated security policy page outlining security controls and user guidance.
  2. Create and maintain a security.txt file to facilitate responsible vulnerability disclosure.
  3. Implement and explicitly declare security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Provide clear incident response contact channels (e.g., security@ or abuse@ email addresses).
  5. Enhance cookie consent mechanisms to cover all storage types and provide granular user controls.

Technical notes

Notes

The website is hosted on AWS infrastructure using Route53 DNS and AWS WAF, indicating robust cloud hosting. The front-end uses jQuery 2.2.4 and Bootstrap for responsive design, complemented by govbr CSS and JS libraries for government branding and accessibility compliance. Google Tag Manager and multiple Google Analytics IDs are deployed for analytics and marketing. The site is mobile optimized with good accessibility features such as skip links and font size controls. Performance is moderate, with asynchronous loading of analytics scripts. No CMS is explicitly detected, suggesting a custom or government-developed platform. The technical stack is modern but could benefit from updating jQuery to a more recent version and consolidating analytics containers for efficiency.
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.
