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

NTP.br is a Brazilian initiative managed by NIC.br in partnership with the Observatório Nacional to provide accurate and secure time synchronization services across Brazil. The website offers public NTP servers, educational content, and configuration guides for various devices. It holds a strong position as a trusted source for time synchronization in Brazil, supported by government and technical institutions. The technical infrastructure uses modern web technologies such as Bootstrap and FontAwesome, with embedded multimedia content to enhance user engagement. The site is mobile optimized and provides clear navigation, although it lacks explicit privacy and cookie policies. Security posture is adequate with HTTPS usage and no visible vulnerabilities, but could be improved by adding security headers and incident response information. Overall, the domain registration and WHOIS data align well with the website's claims, indicating high legitimacy and trustworthiness.

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

7 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. 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"

    • 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';…

  3. 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

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 business operates as a non-commercial public service entity focused on technology infrastructure, specifically time synchronization for internet-connected devices in Brazil. Its competitive advantage lies in its official backing by NIC.br and the Observatório Nacional, providing authoritative and reliable time services. The target audience includes IT professionals, network administrators, and general internet users in Brazil. The organization maintains partnerships with key Brazilian internet governance bodies and promotes related initiatives such as IPv6 adoption and internet quality measurement. The business model is service-oriented with an emphasis on education and infrastructure support rather than direct revenue generation.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and no exposed sensitive data or forms collecting user information. However, it lacks visible security headers such as Content-Security-Policy and X-Frame-Options, which are recommended to mitigate common web attacks. There is no publicly available incident response or vulnerability disclosure policy, which limits transparency and readiness for security incidents. The absence of privacy and cookie policies also indicates gaps in compliance with data protection regulations such as GDPR. Overall, the security posture is functional but could benefit from enhancements to align with best practices and regulatory requirements.

Recommendations

  1. Publish comprehensive privacy and cookie policies to improve transparency and compliance.
  2. Implement security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Provide clear incident response and vulnerability disclosure information accessible to users.
  4. Enhance accessibility features to improve usability for all users.
  5. Add SEO meta tags and Open Graph data to improve search engine visibility and social media sharing.

Technical notes

Notes

The website uses a stable and widely adopted technology stack including Bootstrap for responsive design, FontAwesome for icons, and jQuery for scripting. The HTML structure is valid and the site is mobile optimized, providing a good user experience across devices. Performance is moderate with embedded multimedia content such as YouTube videos. There is no detected CMS or advanced backend technology visible from the frontend. The site does not use active analytics or tracking scripts, which reduces privacy concerns but also limits data-driven insights. Technical risks are low, but modernization opportunities include adding progressive web app features and improving SEO and accessibility compliance.
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.
