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

Lyncas is a Brazilian technology company specializing in IT outsourcing, software factory services, system maintenance, and squad as a service offerings. Positioned as a medium-sized enterprise with over 180 employees, Lyncas serves a diverse client base across multiple sectors, emphasizing digital transformation and innovation. The company maintains a professional online presence with detailed service descriptions, client testimonials, and active social media engagement. Technically, the website is built on WordPress with modern JavaScript libraries and includes integrations for analytics and marketing tools such as Google Tag Manager, Hotjar, and LinkedIn Insight. However, the website suffers from critical security shortcomings, including an invalid SSL certificate, lack of TLS protocol support, missing security headers, and incomplete DNS security configurations. These issues expose the site to potential risks and undermine user trust. The company has implemented basic privacy and cookie policies but lacks visible terms of service, security policies, or incident response information. Strategic improvements in security posture and compliance are recommended to enhance trust and protect business operations.

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

      • 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"

  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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

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

Lyncas operates in the competitive Brazilian technology services market, focusing on IT outsourcing and software development. Its business model targets corporate clients seeking to augment their IT capabilities with specialized teams and agile delivery models. The company demonstrates growth through a portfolio of notable clients and positive testimonials, indicating strong market acceptance. Its digital content strategy includes blogs and resources aimed at educating and engaging its audience. Partnerships and social media presence support brand visibility. However, the absence of explicit security and compliance frameworks may limit appeal to highly regulated sectors. The company’s reliance on third-party hosting and standard CMS platforms suggests moderate operational complexity with opportunities for technical modernization and enhanced security governance.

Security posture

The current security posture of Lyncas.net is weak due to the absence of a valid SSL certificate and lack of support for modern TLS protocols, exposing users to potential interception and data integrity risks. DNS security is minimal, with no DNSSEC enabled and malformed CAA records, increasing vulnerability to DNS spoofing and unauthorized certificate issuance. The DMARC policy is permissive (none) without reporting, limiting email spoofing protection. No security headers or incident response contacts are published, indicating immature security governance. While no critical vulnerabilities like Heartbleed or POODLE are detected, the overall configuration fails to meet best practices for secure web presence. This exposes the company and its clients to reputational and operational risks, especially given the nature of IT services provided. Immediate remediation of SSL/TLS and DNS configurations, along with enhanced policy transparency, is advised.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate supporting TLS 1.2 or TLS 1.3 to secure all web traffic.
  2. Enable HSTS with includeSubDomains and preload directives to enforce HTTPS usage.
  3. Correct and implement CAA DNS records to restrict certificate authorities authorized to issue certificates for the domain.
  4. Enable DNSSEC to protect DNS integrity and prevent spoofing attacks.
  5. Implement a stricter DMARC policy (quarantine or reject) with reporting addresses to mitigate email spoofing.
  6. Publish clear security policies, incident response procedures, and vulnerability disclosure guidelines on the website.
  7. Add security HTTP headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to harden browser security.
  8. Regularly audit and update third-party scripts and marketing tools to minimize privacy risks and comply with data protection regulations.
  9. Consider adding phone contact information with clear labeling to improve customer trust and accessibility.
  10. Enhance accessibility features and conduct usability testing to improve user experience for all visitors.

Technical notes

Notes

The website infrastructure is based on WordPress CMS hosted likely on Hostinger, utilizing common web technologies including jQuery, Swiper.js for sliders, Google reCAPTCHA for bot protection, and Google Tag Manager for analytics and marketing integration. The site employs lazy loading for images and uses GTranslate for multilingual support. Performance is slow with a load time of approximately 17.8 seconds and a page size of about 210 KB, indicating potential optimization opportunities. Mobile optimization is good, with responsive design and viewport settings. SEO is supported by structured data (JSON-LD) and Open Graph metadata, enhancing search engine visibility. However, the lack of a valid SSL certificate and modern TLS support is a critical technical risk. DNS configuration lacks DNSSEC and has malformed CAA records, which could impact domain security. Overall, the technical stack is standard but requires security and performance improvements to support business continuity and growth.
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.
