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

Deen - Agência de Marketing Digital is a small Brazilian digital marketing agency specializing in branding, social media, and website development services. The company targets businesses seeking to enhance their digital presence, primarily within Brazil. The website highlights notable clients and awards, positioning Deen as a recognized player in the digital marketing sector. Technically, the website employs multiple marketing and analytics tools such as Google Analytics, Hotjar, LinkedIn Insight Tag, and Jivochat, indicating a moderate level of digital maturity. However, the site suffers from significant security shortcomings, including an invalid SSL certificate, lack of HTTPS enforcement, and absence of essential security headers and DNS security features. These issues expose the site and its visitors to potential risks and undermine trust. Overall, while the business demonstrates good branding and content quality, the technical and security posture requires urgent improvement to align with industry best practices and regulatory 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.

Priority findings

6 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

Deen operates as a service-based digital marketing agency with a focus on media and branding services. Its market positioning is strengthened by client references and awards, suggesting competitive advantages in quality and recognition. The business model revolves around delivering digital marketing solutions to Brazilian companies, leveraging partnerships and a strong social media presence. Revenue streams likely include project-based contracts for website development, social media management, and branding. The target customer segment includes small to medium-sized enterprises seeking to improve their online visibility. The partnership ecosystem includes subdomains dedicated to partners, indicating collaborative business relationships. Strategic observations highlight the need for enhanced digital security and privacy compliance to support sustainable growth and client trust.

Security posture

The current security maturity level of the website is low, primarily due to the absence of a valid SSL certificate and lack of HTTPS support. This exposes users to risks such as data interception and undermines trust signals. The site does not implement critical security headers or DNS security mechanisms like DNSSEC and CAA records. There is no evidence of privacy policies, cookie consent mechanisms, or incident response procedures, indicating compliance gaps with GDPR and other data protection regulations. The extensive use of third-party tracking and marketing scripts without visible privacy controls further exacerbates privacy risks. Incident response readiness appears minimal, with no dedicated security contact channels. Overall, the security culture and practices require significant enhancement to protect business operations and customer data effectively.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate to enable secure HTTPS connections site-wide.
  2. Implement and publish comprehensive privacy and cookie policies with explicit consent mechanisms to comply with GDPR and other regulations.
  3. Configure security headers such as Content-Security-Policy, X-Frame-Options, and Referrer-Policy to mitigate common web vulnerabilities.
  4. Enable DNSSEC and CAA records to strengthen DNS security and certificate issuance controls.
  5. Establish an incident response plan and provide clear security contact channels (e.g., security@deen.com.br).
  6. Audit and minimize third-party tracking scripts to reduce privacy risks and improve user trust.
  7. Regularly monitor and update the website's security posture and compliance status.

Technical notes

Notes

The website utilizes a modern front-end with SVG graphics, video backgrounds, and asynchronous loading of multiple third-party scripts including Google Analytics, Hotjar, LinkedIn Insight Tag, and Jivochat. However, the absence of a valid SSL certificate and support for modern TLS protocols severely impacts security and user trust. Performance is slow with a high page size (~1MB) and long load times (~10.7 seconds), indicating potential optimization opportunities. Mobile optimization is basic, with conditional loading of mobile-specific styles and scripts. No CMS or hosting provider is explicitly detected. The DNS configuration is standard but lacks advanced security features like DNSSEC and CAA. Overall, the technical infrastructure supports the business needs but requires modernization and security hardening to reduce technical debt and operational risks.
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.
