Risk levelMedium

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

Banrisul is a large, state-owned multiple bank operating primarily in the southern region of Brazil, specifically Rio Grande do Sul. It offers a range of banking and financial services including commercial banking, development banking, leasing, real estate credit, financing, and investment. The website serves as a portal for internet banking and related services, targeting residents and businesses in its regional market. The business model focuses on public banking services with a regional market position. Technically, the website infrastructure appears outdated, using framesets and lacking modern web technologies or CMS indicators. Performance is moderate but mobile optimization and accessibility are poor. The absence of modern security protocols and an invalid SSL certificate indicate significant technical debt and security risks. No advanced frameworks or analytics tools are detected, and SEO is basic. From a security perspective, the site lacks a valid SSL certificate and does not support any TLS protocols, exposing users to potential risks. There are no HTTP security headers, no privacy or cookie policies, and no visible incident response or vulnerability disclosure mechanisms. This reflects a low security maturity level and potential compliance gaps with data protection regulations. Overall, the website requires urgent improvements in security posture, modernization of technical infrastructure, and implementation of privacy and compliance policies to enhance trust and protect users. Strategic investments in security and digital modernization are recommended to align with industry standards 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

4 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 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

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

Banrisul holds a strong regional presence as a public state-owned bank in Brazil's Rio Grande do Sul state, focusing on multiple banking services. Its competitive advantage lies in its government backing and regional specialization. The business model is centered on providing comprehensive banking and financial services to individuals and businesses in southern Brazil. Revenue streams likely include interest income, fees from leasing and credit products, and investment services. The target customer segments are regional residents and enterprises requiring banking solutions. Growth indicators are not directly visible from the website but the bank's public status suggests stable operations. The partnership ecosystem is not evident from the website content. Strategic observations highlight the need for digital transformation and enhanced security to maintain market position and customer trust.

Security posture

The current security posture of the Banrisul website is weak. The absence of a valid SSL certificate and lack of support for TLS protocols expose users to interception and man-in-the-middle attacks. Missing security headers and no HSTS implementation further degrade security. There is no evidence of published security policies, incident response plans, or vulnerability disclosure processes, indicating low organizational security maturity. Compliance with GDPR or similar data protection regulations is not demonstrated. The lack of privacy and cookie policies also suggests poor data protection practices. Incident response readiness and security culture indicators are not visible. These gaps pose business risks including reputational damage and regulatory penalties.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate immediately to secure all website communications.
  2. Enable and enforce modern TLS protocols (TLS 1.2 or TLS 1.3) and disable all insecure protocols.
  3. Implement HTTP security headers such as HSTS with includeSubDomains and preload to prevent protocol downgrade attacks.
  4. Publish comprehensive privacy, cookie, and security policies to improve transparency and regulatory compliance.
  5. Establish a vulnerability disclosure program and publish a security.txt file to facilitate responsible reporting.
  6. Modernize the website infrastructure by replacing framesets with responsive design and improving accessibility and SEO.
  7. Implement incident response procedures and provide clear security contact channels for reporting issues.
  8. Adopt security frameworks such as ISO 27001 or NIST to formalize security governance and controls.
  9. Enhance user trust by adding verified contact information and social media presence.
  10. Regularly audit and update DNS records to include DNSSEC and CAA for improved domain security.
Technical notes

Notes

The website uses an outdated frameset HTML structure, which negatively impacts usability, SEO, and mobile experience. No modern JavaScript libraries, frameworks, or CMS platforms are detected. DNS records show basic email SPF configuration but lack DNSSEC and CAA records, reducing domain security. SSL configuration is critically deficient with no valid certificate and no TLS protocols enabled, exposing the site to security risks. Performance is moderate with a load time of approximately 3.1 seconds and 27 resources loaded. The site lacks mobile optimization and accessibility features. Meta tags are present but limited to basic SEO. Overall, the technical infrastructure shows signs of legacy systems and requires modernization to meet current web standards and security best practices.
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.
