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

9 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

      What to do: Add a comprehensive privacy policy page and link to it prominently

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

Avantia operates in the technology sector with a focus on AI applications for security and process optimization. Its business model is B2B, providing proprietary AI solutions to improve operational efficiency and security for clients. The company maintains active social media channels on Facebook, Instagram, LinkedIn, and YouTube, supporting brand awareness and customer engagement. The website content and metadata emphasize innovation and technology, targeting medium-sized enterprises in Brazil. The use of advanced analytics and marketing tools suggests a growth-oriented approach. However, the absence of explicit certifications or detailed business registrations on the site limits external validation of its market standing. The company appears to be well-positioned within its niche but could benefit from enhanced transparency and published credentials to strengthen credibility.

Security posture

Avantia demonstrates a good security posture with HTTPS enabled and no detected exposed sensitive information or vulnerable libraries in the website content. The use of security and analytics scripts is standard for modern websites, but the lack of published security policies, incident response plans, or dedicated security contact emails indicates a gap in formal security governance transparency. No security headers were detected in the provided data, which could be improved to enhance protection against common web attacks. The cookie consent mechanism is present, supporting privacy compliance. Overall, the security maturity is moderate, suitable for a technology company but with opportunities to formalize and communicate security practices more clearly to users and clients.

Recommendations

  1. Publish a comprehensive security policy and incident response plan on the website.
  2. Add explicit GDPR compliance statements and data protection officer contact information if applicable.
  3. Implement and configure security HTTP headers such as Content-Security-Policy, X-Content-Type-Options, and Strict-Transport-Security.
  4. Provide clear terms of service to inform users about website usage and data handling.
  5. Enhance accessibility features and conduct regular security audits to maintain a strong security posture.

Technical notes

Notes

The website is built on WordPress CMS with a modern tech stack including jQuery, Select2, PDF.js, and multiple analytics and marketing tools such as Google Tag Manager, Facebook Pixel, Hotjar, and LinkedIn Insight Tag. Hosting is supported by Microsoft Azure DNS, indicating a robust cloud infrastructure. The site is mobile optimized with responsive design and good SEO practices implemented via Yoast SEO plugin. Performance is moderate, with asynchronous loading of scripts to improve speed. Accessibility is basic but could be enhanced. No critical technical vulnerabilities were detected in the HTML content. The technical infrastructure supports the business goals effectively but could benefit from improved security headers and formalized privacy and security documentation.
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.
