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

Bloomberg Brasil operates as a regional branch of Bloomberg L.P., providing the Bloomberg Professional service, a leading financial data and analytics platform. The website targets financial professionals and institutions, offering comprehensive solutions including real-time market data, order execution, data management, and trading platforms. The business model is subscription-based, serving enterprise clients with a strong market position globally and regionally. The website is professionally designed, content-rich, and well-branded, reflecting Bloomberg's global standards. Technically, the site leverages WordPress CMS with modern JavaScript libraries, Google Tag Manager for analytics, and New Relic for performance monitoring. It employs SEO best practices and is mobile-optimized, though accessibility features are basic. Performance is moderate, with room for optimization. Security posture is strong with HTTPS enforced, use of security monitoring tools, and no exposed sensitive data. However, explicit security policies and incident response contacts are not published, representing an area for improvement. Privacy compliance is robust with clear privacy and cookie policies and consent mechanisms aligned with GDPR. Overall, the website presents a low risk profile with high business credibility and technical maturity. Strategic recommendations include publishing a dedicated security policy, incident response contacts, and vulnerability disclosure information to enhance trust and compliance.

  3. (c) Business continuity, backups and crisis management: Not visible from outside
  4. (d) Supply chain security: Not visible from outside

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

No critical or high findings. These medium findings are worth fixing next.

  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.

    • Medium

      Missing Permissions-Policy header

      Controls browser features and APIs

      What to do: Implement a Permissions-Policy to restrict feature access

      • OWASP Secure Headers: OWASP Secure Headers Project recommends Permissions-Policy: accelerometer=(), autoplay=(), camera=(), cross-origin-isolated=(),…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Medium

      Privacy policy may not be GDPR compliant

      Privacy policy lacks explicit GDPR compliance elements

      What to do: Update privacy policy to explicitly address GDPR requirements and user rights

  3. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Medium

      DMARC not enforcing

      DMARC policy is set to "none"

      What to do: Gradually move to "quarantine" then "reject" policy

    • Medium

      No DKIM record found

      DKIM adds cryptographic signatures to emails

      What to do: Configure DKIM with your email provider

    • Medium

      No MTA-STS Policy

      MTA-STS enforces TLS for email delivery

      What to do: Implement MTA-STS to prevent downgrade attacks

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

Bloomberg Brasil is positioned as a key regional provider of Bloomberg's financial services, targeting a broad spectrum of financial professionals including analysts, traders, compliance officers, and executives. The company leverages its global brand and technology to offer integrated financial data, analytics, and trading solutions. Revenue streams are primarily subscription-based, supported by a comprehensive product suite. The partnership ecosystem includes related Bloomberg services such as Bloomberg Law, Bloomberg Tax, and Bloomberg Government. Growth indicators include active content updates, webinars, and localized support. The company's operations reflect a mature, enterprise-level business with strong market penetration in Brazil and Latin America.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and integration of monitoring tools like New Relic. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. Privacy and cookie policies are comprehensive and include consent mechanisms. However, the absence of a publicly available security policy, incident response contact information, and vulnerability disclosure policy limits transparency. There is no evidence of security headers explicitly declared in the HTML, though they may be present at the server level. The site would benefit from enhanced accessibility and explicit security documentation to meet best practices and regulatory expectations.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  3. Implement and publicize a vulnerability disclosure policy or security.txt file.
  4. Enhance website accessibility features to improve compliance and user experience.
  5. Regularly audit and update third-party scripts and dependencies to mitigate vulnerabilities.

Technical notes

Notes

The website is built on WordPress CMS with integration of modern JavaScript libraries and APIs such as Vimeo Player and Google Tag Manager. It uses Yoast SEO plugin for search engine optimization and WPBakery Page Builder for content management. Performance monitoring is implemented via New Relic Browser. The site is mobile responsive with good SEO metadata and structured data (JSON-LD). Hosting provider details are not explicit. The site shows moderate performance with potential for optimization. Technical debt appears low, but accessibility could be improved. The technology stack is mature and aligns with enterprise standards.
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.
