Risk levelMedium

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

Hospital Geral de Caxias do Sul is a large healthcare institution in Brazil providing a comprehensive range of medical services including oncology, radiotherapy, intensive care, and specialized treatments. The hospital is a regional reference in high complexity care and is accredited by the ONA, reflecting its commitment to quality and safety. The website serves patients, healthcare professionals, and the local community, also offering educational programs such as medical residency and permanent education. Technically, the site uses a modern tech stack including Apache server, Laravel framework, and various JavaScript libraries for UI and analytics. However, the site lacks a valid SSL certificate and does not serve content over HTTPS, which is a critical security deficiency. Security headers are minimal, and no privacy or cookie policies are found, indicating compliance gaps. The site includes multiple contact phone numbers, a physical address, and social media links, enhancing business credibility. Overall, the website is functional and content-rich but requires urgent improvements in security and privacy compliance to protect users and enhance trust.

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. 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';…

  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

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

The hospital operates primarily in the healthcare sector, targeting patients and medical professionals in the Caxias do Sul region. It leverages public health system support (SUS) and offers specialized medical services and educational programs, positioning itself as a key regional healthcare provider. The presence of a laboratory subdomain and partnerships with educational and marketing institutions indicate a collaborative ecosystem. The business model focuses on service delivery and education, with trust signals such as ONA accreditation and active social media engagement. Growth opportunities include digital transformation and enhanced patient engagement through improved website security and privacy features.

Security posture

The current security posture is weak due to the absence of HTTPS and a valid SSL certificate, exposing users to potential data interception and man-in-the-middle attacks. The lack of advanced security headers and no implementation of DNS-based protections (DMARC, DNSSEC, CAA) further increase risk. No incident response or vulnerability disclosure information is available, limiting transparency and readiness. While CSRF tokens and HttpOnly cookies are used, the overall security framework is insufficient for a healthcare provider handling sensitive data. Immediate remediation is necessary to meet regulatory and best practice standards.

Recommendations

  1. Install and enforce HTTPS with a valid SSL/TLS certificate to secure all communications.
  2. Implement comprehensive privacy and cookie policies with user consent mechanisms to comply with GDPR and local regulations.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection.
  4. Publish a security.txt file and establish clear incident response contacts to improve transparency and trust.
  5. Regularly audit and update third-party libraries and frameworks to mitigate vulnerabilities.

Notes

The website is hosted on an Apache server and built using the Laravel PHP framework, as indicated by session cookies. It uses modern front-end libraries including Fancyapps UI for modals, Toastify for notifications, and jspdf for PDF generation. Google Fonts and Fontshare provide typography, while Google Analytics tracks user behavior. The site is mobile optimized with responsive design and accessible navigation. However, performance metrics are missing, suggesting a need for monitoring and optimization. The absence of HTTPS and modern TLS protocols is a significant technical risk. The site lacks DNS security extensions and email authentication records, which are recommended for domain protection.
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.
