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

8 findings rated critical or high. Fix these first.

  1. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  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"

    • 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

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 · found on this site
  • 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

AVB operates in the manufacturing sector with a niche in sustainable steel production. Its market positioning leverages environmental credentials and certifications to differentiate from competitors. The business model focuses on supplying steel products and industrial gases primarily to construction and industrial clients. Revenue streams likely include product sales and services related to industrial gases. The company targets both domestic Brazilian markets and international stakeholders, as evidenced by multilingual site support and investor relations. Partnerships with Grupo Ferroeste and presence on multiple digital platforms indicate a well-established ecosystem. Growth indicators include active sustainability reporting and participation in industry events. Strategic observations highlight a focus on ESG compliance and digital engagement.

Security posture

The website exhibits a mature security posture with HTTPS enforced and GDPR cookie compliance implemented. Use of Google reCAPTCHA on forms reduces spam risk. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, explicit security headers such as Content-Security-Policy and X-Frame-Options are not evident and should be implemented to enhance protection against common web attacks. Incident response and security policies are not publicly documented on the site, which could be improved to increase transparency and readiness. Overall, the security posture is good but could benefit from additional hardening and documentation.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a clear security policy and incident response plan accessible to users and partners.
  3. Regularly audit and update WordPress core and plugins to mitigate vulnerabilities.
  4. Enhance transparency by providing vulnerability disclosure or security contact information.
  5. Continue to improve accessibility and mobile optimization to maintain user experience standards.

Technical notes

Notes

The website is built on WordPress CMS using WPBakery Page Builder and Slider Revolution for content and visual presentation. It employs modern JavaScript libraries including jQuery and ApexCharts for interactive content. Performance optimizations include lazy loading of images and scripts, and use of a GDPR compliance plugin for cookie management. Hosting DNS is managed via Microsoft Azure DNS servers, indicating enterprise-grade infrastructure. Google Tag Manager and Google Analytics are integrated for marketing and analytics. The site is responsive and includes accessibility features such as the VLibras widget for Brazilian sign language. Technical risks are minimal but depend on timely updates of WordPress and plugins to avoid security issues.
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.
