Risk levelMedium

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

Renna is a Brazilian manufacturing company specializing in furniture components with over 20 years of market presence. The company offers a wide range of products including telescopic rails, pistons, power towers, LEDs, handles, and furniture feet, targeting furniture manufacturers and retailers. Their website reflects a medium-sized business with consistent branding and a good content quality level. Technically, the site uses common web technologies such as jQuery, Bootstrap, and Owl Carousel, hosted on Microsoft Azure DNS infrastructure. However, the website suffers from slow performance and lacks a valid SSL certificate, which impacts security and user trust. The presence of multiple marketing and analytics tools indicates moderate digital maturity but also raises privacy considerations. Security posture is weak due to invalid SSL, lack of modern TLS protocols, and misconfigured SPF records. No explicit privacy, cookie, or terms of service policies were found, though LGPD consent checkboxes are present in forms, showing some compliance awareness. Overall, Renna's digital presence supports its business operations but requires significant security and compliance improvements to enhance trust and protect user data.

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

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

Renna holds a strong position in the furniture components manufacturing sector in Brazil, serving over 2500 clients with a comprehensive product catalog. Their business model focuses on manufacturing and distributing a diverse range of furniture parts and accessories. The company leverages partnerships with customer support and recruitment platforms, indicating an integrated operational ecosystem. Marketing efforts include the use of RD Station and Google Tag Manager for analytics and user engagement. The target audience includes furniture manufacturers, retailers, and possibly end consumers seeking furniture components. Growth indicators include a large product catalog and active social media presence. Strategic observations suggest opportunities to improve digital security and compliance to better align with regulatory requirements and customer expectations.

Security posture

The current security posture of Renna's website is weak. The absence of a valid SSL certificate and disabled TLS protocols expose users to potential data interception and man-in-the-middle attacks. The presence of multiple SPF records causes email authentication failures, increasing the risk of phishing and spoofing. Lack of HSTS, DNSSEC, and CAA records further weakens DNS and transport security. No published security policy or incident response contacts limit transparency and readiness for security incidents. While LGPD consent mechanisms in forms indicate some data protection awareness, the overall security configuration is insufficient for protecting sensitive customer data and maintaining trust. Immediate remediation is required to secure communications, improve email authentication, and publish clear security policies.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate to enable secure HTTPS connections.
  2. Enable modern TLS protocols (TLS 1.2 or TLS 1.3) and disable insecure versions.
  3. Consolidate SPF records into a single valid record to ensure proper email authentication.
  4. Implement HSTS headers to enforce HTTPS usage and prevent protocol downgrade attacks.
  5. Enable DNSSEC to protect DNS integrity and prevent spoofing.
  6. Add CAA DNS records to restrict certificate issuance to authorized authorities.
  7. Publish a comprehensive privacy policy, cookie policy, terms of service, and security policy on the website.
  8. Provide clear incident response contact information for security issues.
  9. Review and optimize website performance to reduce load times and improve user experience.
  10. Enhance privacy compliance by auditing data collection and retention practices.

Technical notes

Notes

The website is built using a combination of jQuery, Bootstrap, Owl Carousel, FancyApps UI, Lodash, and other JavaScript libraries, indicating a modern but somewhat traditional front-end stack. Hosting is supported by Microsoft Azure DNS infrastructure. Performance metrics show a slow load time (~11.7 seconds) and a large page size (~730 KB), suggesting optimization opportunities. Mobile optimization is good with responsive design and mobile-specific menus. SEO is supported by meta tags and structured JSON-LD data for the organization. However, the lack of a valid SSL certificate and disabled TLS protocols represent critical technical risks. Multiple external scripts for analytics and marketing increase complexity and potential privacy concerns. Overall, the technical infrastructure supports business needs but requires modernization and security hardening to reduce risks and improve operational efficiency.
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.
