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

MDN Digital, operated by Maldonado Digital LTDA, is a Brazilian-based marketing and technology consultancy specializing in supporting startups, scale-ups, and enterprises to plan, develop, and monetize digital products efficiently. The company positions itself as an extension of clients' marketing and technology departments, offering a comprehensive suite of services from strategic planning to product development and performance marketing. Their market presence is reinforced by global client experience and a proprietary methodology focused on innovation and results. Technically, the website is built on the Webflow platform, leveraging modern web technologies such as Google Tag Manager, Calendly integration, and Finsweet Cookie Consent for privacy compliance. The site demonstrates excellent design quality, mobile optimization, and SEO practices, reflecting a mature digital infrastructure. Hosting is managed by Webflow, ensuring reliable performance and security. From a security perspective, the website enforces HTTPS with strong SSL configuration and includes standard security headers. Cookie consent mechanisms are implemented, supporting GDPR compliance. However, the site lacks a dedicated security policy and incident response contact information, which are recommended for enhanced transparency and readiness. No vulnerabilities or exposed sensitive data were detected in the analyzed content. Overall, MDN Digital presents a professional, trustworthy, and well-structured online presence aligned with its business objectives. The risk profile is low, with recommendations focusing on improving security policy disclosures and incident response readiness to further strengthen trust and compliance.

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

3 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 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';…

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

MDN Digital operates in the technology consulting sector, targeting startups, scale-ups, and enterprises seeking digital transformation and innovation. Their competitive advantage lies in a multidisciplinary, English-fluent team, a proprietary methodology, and a global client base. The business model combines monthly fee-based dedicated teams with project-based engagements, providing flexibility and scalability. Revenue streams likely include consulting fees, development services, and performance marketing management. The company emphasizes high-quality deliverables, client retention, and long-term partnerships, supported by testimonials and case studies. Strategic observations include a focus on innovation, customer-centric solutions, and leveraging technology partners to enhance service offerings.

Security posture

The website demonstrates a solid security posture with HTTPS enforced and multiple security headers present. Cookie consent and privacy policies indicate awareness of data protection regulations. However, the absence of a published security policy and incident response contacts suggests room for improvement in transparency and preparedness. No signs of malware, phishing, or exposed credentials were found. The use of third-party scripts is controlled via Google Tag Manager, reducing risk exposure. Overall, the security maturity is good but could benefit from formalized policies and vulnerability disclosure mechanisms.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  3. Implement a security.txt file to facilitate responsible vulnerability disclosure.
  4. Regularly review and audit third-party scripts and integrations for security risks.
  5. Enhance accessibility features to meet higher compliance standards and improve user experience.

The website is built using Webflow CMS and hosting, ensuring modern infrastructure and reliable performance. The tech stack includes Google Tag Manager for analytics and script management, Calendly for scheduling, and Finsweet Cookie Consent for privacy compliance. The site loads quickly, is mobile-optimized, and uses web fonts loaded asynchronously. SEO is supported by proper meta tags and Open Graph data. No technical debt or deprecated technologies were detected. Opportunities exist to improve accessibility and formalize security-related technical 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.
