Medium risk. 7 critical or high findings in Security headers, GDPR outside view and 1 other check.

Security score

64/100

Risk levelMedium

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

The website argoenergia.com.br is currently inaccessible due to a Cloudflare Web Application Firewall (WAF) blocking page, preventing access to any substantive content. As a result, no direct business information, metadata, or contact details are available for analysis. The domain is associated with the energy sector in Brazil based on the domain extension and DNS records, but no further business insights can be derived from the blocked content. The technical infrastructure includes Cloudflare protection, a valid SSL certificate with basic configuration, and DNS records with SPF and DMARC policies indicating some email security measures. However, the absence of DNSSEC and CAA records suggests room for improvement in DNS security. Performance metrics indicate a slow load time, likely due to the WAF challenge page. Security posture is moderate due to HTTPS and email authentication but lacks advanced security headers and HSTS enforcement. Overall, the site’s security and compliance posture cannot be fully assessed due to the blocking mechanism.

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. 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 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';…

  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

      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

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

Due to the Cloudflare WAF blocking, no direct business intelligence data such as company size, market position, or business model could be extracted. The domain is linked to the energy sector in Brazil, but no information on partnerships, subsidiaries, or certifications is available. The lack of visible privacy policies, contact information, or terms of service limits the ability to assess business credibility or compliance maturity. The site appears to rely on Cloudflare for security and hosting, indicating a focus on protecting infrastructure but potentially at the cost of user accessibility.

Security posture

The security posture shows some strengths including valid HTTPS with a non-self-signed certificate, SPF and DMARC records with a reject policy to prevent email spoofing, and Cloudflare WAF protection. However, the absence of DNSSEC and CAA records, lack of HSTS, missing security headers, and no visible vulnerability disclosures or incident response contacts highlight gaps in comprehensive security management. The blocking by Cloudflare WAF, while protective, also limits transparency and user access, which may impact trust and usability. No vulnerabilities or exposed sensitive data were detected in the limited accessible content.

Recommendations

  1. Enable and enforce HTTP Strict Transport Security (HSTS) with includeSubDomains and preload flags to strengthen HTTPS security.
  2. Implement essential security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to mitigate common web attacks.
  3. Configure DNSSEC and CAA records to enhance DNS security and certificate issuance control.
  4. Review Cloudflare WAF rules to balance security with user accessibility, ensuring legitimate users are not blocked unnecessarily.
  5. Publish clear privacy, cookie, and terms of service policies along with contact information to improve compliance and user trust.
Technical notes

Notes

The website is hosted behind Cloudflare, which provides DNS, CDN, and WAF services. The SSL certificate is valid but lacks detailed cipher suite information and HSTS is not enabled. DNS records include A, AAAA, MX, NS, and TXT with SPF and DMARC configured correctly, but DNSSEC and CAA are not enabled. The site performance is poor with a load time exceeding 14 seconds, likely due to the WAF challenge page. No CMS or frameworks are detectable from the limited HTML content. The site lacks SEO metadata and accessibility features, and no analytics or marketing tools are evident. Overall, the technical infrastructure is basic with significant room for modernization and optimization.
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.
