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

Sayerlack is a leading Brazilian multinational specializing in the manufacturing and distribution of wood paints, varnishes, and stains, serving Latin America and over 90 countries globally. The company targets professionals such as architects, decorators, interior designers, carpenters, painters, and hobbyists, offering tailored solutions and extensive product lines. Their digital presence includes multilingual support, educational content, and interactive tools like digital color charts. Technically, the website employs modern front-end technologies including jQuery, Slick Carousel, FontAwesome, and Tailwind CSS, hosted on Microsoft Online infrastructure. However, the site suffers from critical security shortcomings, notably the absence of a valid SSL certificate and lack of modern TLS protocols, which undermines user trust and data protection. From a security perspective, while basic email protection via SPF is configured and CSRF tokens are implemented in forms, the lack of HTTPS, HSTS, DMARC, and other security headers exposes the site to potential risks. Privacy and cookie policies are present with a consent mechanism, but GDPR compliance is not fully addressed. No explicit security or incident response policies are found. Overall, Sayerlack's website reflects a mature business with strong market positioning but requires urgent security enhancements to protect user data and maintain trust. Strategic improvements in SSL deployment, security headers, and compliance frameworks are recommended to align with best practices and regulatory requirements.

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

7 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 Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

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

Sayerlack holds a dominant position in the Latin American wood finishing market, leveraging a large manufacturing footprint and global distribution network. Their business model focuses on high-performance, customized wood finishing products, supported by technical expertise and customer engagement through digital channels. The company benefits from a broad target audience spanning professionals and DIY consumers, enhancing market reach. Their partnership with marketing firms like MKT Now indicates a strategic approach to brand development and digital marketing. Growth indicators include active content marketing, multilingual support, and extensive product catalogs. The company emphasizes sustainability and innovation, aligning with modern market demands.

Security posture

The current security posture of Sayerlack's website is weak due to the absence of a valid SSL certificate and disabled TLS protocols, resulting in unencrypted traffic and potential exposure to interception. While SPF is configured for email authentication, the lack of DMARC and DNSSEC reduces email security robustness. The site implements CSRF tokens in forms, indicating some security awareness. However, missing HSTS, OCSP stapling, and session resumption features further weaken security. No dedicated security or incident response policies are publicly available, limiting transparency and preparedness. Privacy policies exist but lack explicit GDPR compliance. Overall, the site is vulnerable to common web threats and requires immediate remediation to protect user data and maintain regulatory compliance.

Recommendations

  1. Deploy a valid SSL/TLS certificate and enable HTTPS site-wide to secure data in transit.
  2. Implement modern TLS protocols (TLS 1.2 or 1.3) and disable outdated protocols to enhance encryption.
  3. Add HSTS header with includeSubDomains and preload options to enforce secure connections.
  4. Publish a DMARC record and consider DNSSEC to strengthen email security and prevent spoofing.
  5. Develop and publish a security.txt file and a clear vulnerability disclosure policy to improve transparency.
  6. Enhance privacy policy to explicitly address GDPR and other relevant data protection regulations.

Technical notes

Notes

The website uses a combination of jQuery, Slick Carousel, FontAwesome, and Tailwind CSS for front-end development, indicating a modern but somewhat traditional tech stack. Hosting is managed via Microsoft Online DNS services. Performance metrics show a slow load time (~15 seconds) and a large page size (~2MB) with many resources (216), suggesting optimization opportunities. Mobile optimization is good with responsive design and media queries. SEO is basic with meta descriptions and multilingual support but lacks advanced structured data like JSON-LD. Security configurations are poor, with no valid SSL and no modern security headers, posing risks to business operations and user trust.
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.
