Banco do Brasil improves collaboration and security with Windows 11 Enterprise | Microsoft Customer Stories
How one of the largest banks in Latin America unifies 86,000+ employees on a single, secure platform. This customer story shows how Banco do Brasil standardized on Windows 11 Enterprise to simplify operations across thousands of branches, strengthen security with BitLocker and Windows Hello for Business, and modernize deployment with Microsoft Intune and Windows Autopilot. Collaboration surged across the bank, with Teams usage rising 117%. Read the customer story to see what the results could mean for your organization.
Why did Banco do Brasil move to Windows 11 Enterprise?
Banco do Brasil wanted to standardize the digital experience for more than 86,000 employees working across thousands of branches, offices, and home offices. Different operating systems were creating:
- Inconsistent user experiences
- Limited collaboration (especially beyond the browser)
- Complex, fragmented device management and security
The pandemic accelerated remote work and drove heavy use of Microsoft Teams. When employees started returning to the office, it became clear they needed a consistent, hybrid-ready work environment that worked the same way at home, in branches, and at headquarters.
By migrating thousands of devices to Windows 11 Enterprise and standardizing on Microsoft 365 E5 and Microsoft Teams, Banco do Brasil set out to:
- Unify the employee experience across locations
- Strengthen security with modern, built-in protections
- Improve collaboration and communication
- Simplify deployment and management at scale
The rollout was completed in about four months, from headquarters to thousands of branches, creating a consistent, modern platform for future initiatives like AI and automation.
How did Windows 11 Enterprise improve collaboration and user experience?
After moving to Windows 11 Enterprise and modern Microsoft 365 tools, Banco do Brasil reshaped how employees collaborate day to day.
Key collaboration and experience gains included:
- 117% increase in daily Microsoft Teams messages, showing more frequent and effective communication among employees.
- A consistent desktop experience across branches, offices, and home offices, reducing friction when people move between locations.
- Native, richer use of Microsoft solutions (like Teams and Microsoft 365 apps) instead of being limited to web-only experiences on older platforms.
Authentication and access also became smoother:
- Windows Hello for Business with facial and fingerprint biometrics simplified logins and reduced support calls.
- Single sign-on (SSO) between the operating system and web applications, enabled by Microsoft Entra, improved the overall user journey.
Behind the scenes, tools like Microsoft Intune and Windows Autopilot made it easier to deploy and support devices across thousands of locations, so employees receive a ready-to-work, standardized environment with less downtime.
What security and management benefits did the migration deliver?
Banco do Brasil used the Windows 11 Enterprise migration to rethink both security and device management.
Security improvements included:
- Disk encryption with BitLocker and native encryption features to protect data at rest.
- Microsoft Defender for Endpoint for real-time protection, reduced attack surface, and conditional access based on device health.
- Microsoft Entra for advanced identity capabilities like Multi-Factor Authentication (MFA) and Conditional Access, helping protect data even if a device is lost or stolen.
- Windows Hello for Business with biometric authentication (facial and fingerprint), which is more secure than passwords and also easier for users.
Management and operations also became more streamlined:
- Microsoft Intune and Windows Autopilot enabled centralized, flexible management of devices across thousands of branches.
- New devices can be managed natively from the cloud, thanks to integration between Microsoft Entra and Intune.
- The organization shifted its security focus from on-premises infrastructure to identity-centric, cloud-based management, overcoming previous authentication and security barriers.
With this foundation in place, Banco do Brasil is now moving into the next phase: using Microsoft 365 Copilot and Microsoft Copilot Studio to bring AI and automation into everyday work, while maintaining strong controls and security.
