When a national stock exchange hands phones to its staff, security is not a nice-to-have. It is the whole job. That is the backdrop for B3 Android Enterprise, the move by B3, the Brazilian stock exchange, to put secure, AI-ready devices in the hands of 1,000 employees. Remarkably, it finished the rollout in under two weeks. It is a clear example of how a heavily regulated financial institution can modernize its mobile workforce without loosening its grip on security. Here is what B3 did, why it chose Android, and what other businesses can take from it.
| Quick Answer B3, the Brazilian stock exchange, moved its management workforce to Android Enterprise on Samsung devices. Using zero-touch enrollment, its IT team deployed secure, compliant phones to 1,000 employees in under two weeks, covering both company-owned and bring-your-own-device users. Android’s multi-layered security, including hardware cryptography, app sandboxing, AI threat detection, and Managed Google Play, protects sensitive financial data, while built-in Google Gemini features boost productivity. B3 projects around 30 percent cost savings over the next decade, and employees gained larger 7-inch screens and longer battery life. |
Key Takeaways
- The B3 Android Enterprise rollout equipped 1,000 employees with secure devices in under two weeks.
- Zero-touch enrollment let B3’s IT team deploy phones at scale without hands-on setup for each device.
- Multi-layered security and AI threat detection keep the exchange’s sensitive financial data protected.
- Built-in Google Gemini AI supports content creation, information access, and task optimization for staff.
- B3 projects roughly 30 percent cost savings over the next 10 years, funding more frequent hardware refreshes.
Who Is B3, and What Was the Challenge?
B3 is the Brazilian stock exchange, and one of the largest financial market infrastructure providers in the world. Its services stretch from equities and fixed income to vehicle leasing control. As a regulated financial institution, B3 has to meet strict security and compliance rules at every level, including on the phones its people carry.
That created a hard balance to strike. B3’s operations teams need to be available around the clock, so their devices must be productive and always reachable. At the same time, every device has to satisfy demanding regulatory requirements. The company’s older setup made that difficult. Device rollouts required heavy coordination and in-person support, screens were a cramped 5 inches, and battery life could not keep up with 24/7 work.
Why B3 Chose Android Enterprise
B3 selected Android Enterprise after extensive testing of both major mobile ecosystems across every benchmark. According to Raul Chavarria, an IT senior manager at the company, the deciding factor was security. Android Enterprise offers multi-layered protection, including hardware cryptography, app sandboxing, and AI threat detection, which suited a business handling sensitive financial data.
Cost and consistency mattered too. Working with Samsung as its device provider, B3 found a budget-friendly price point that did not force a trade-off on performance. That let the company give everyone a consistent experience, from frontline staff to executives, on the same trusted platform. For more on the mobile platform underneath all this, our guide to the newest Android 17 features covers where the operating system is heading.
Inside the B3 Android Enterprise Rollout: 1,000 Devices in Two Weeks
The headline result is speed. B3 equipped most of its workforce, covering both its fully managed fleet and its bring-your-own-device employees, in less than two weeks. The tool that made it possible is Android Enterprise zero-touch enrollment.
With zero-touch enrollment, a device arrives already set to configure itself the moment it is switched on. There is no need to touch each phone by hand. From that point, B3’s IT team manages every device through a single centralized dashboard. The team sets and enforces security policies across the whole fleet. Managed Google Play adds another layer, letting the team control exactly where and how apps are distributed.
| Worth Knowing Zero-touch enrollment is the quiet hero of this story. It turns what used to be a slow, in-person device rollout into a hands-off process, which is how a team can bring 1,000 secure phones online in under two weeks rather than months. |
How Android Enterprise Protects Financial Data
Security is the reason B3 made the switch, so it is worth breaking down the layers that keep its data safe. Each one addresses a different kind of risk.
| Security Layer | What It Does |
| Hardware cryptography | Encrypts data at the chip level, protecting it even if a device is lost |
| App sandboxing | Isolates each app so a problem in one cannot spread to others or the system |
| AI threat detection | Spots and flags suspicious activity in real time |
| Managed Google Play | Controls which apps can be installed and how they are distributed |
| Centralized dashboard | Lets IT set and enforce security policies across every device at once |
Together, these layers let B3 keep tight control without slowing its people down. The IT team can prove compliance to regulators, while employees simply use apps that have already been vetted and secured behind the scenes.
Better Devices, Happier Employees
A security upgrade only works if people actually want to use the new tools. Here, the hardware change won staff over. B3 moved its team from cramped 5-inch screens to lightweight devices with 7-inch displays, higher refresh rates, and longer-lasting batteries.
| Before | With Android Enterprise |
| Rollouts needed heavy coordination and in-person setup | Zero-touch enrollment, 1,000 devices in under two weeks |
| Small 5-inch screens, hard to read messages | Lightweight 7-inch screens with higher refresh rates |
| Battery life could not support 24/7 work | Longer-lasting batteries for all-day availability |
| Higher long-term device costs | Around 30% projected savings over 10 years |
The response from employees has been strongly positive. The new devices comfortably run a wide range of business applications. That keeps B3’s mostly office-based team connected through internal and third-party web apps without friction.
Gemini AI and a Projected 30% in Savings
B3 is not just securing its phones. It is putting AI to work on them. The company is expanding its use of AI to boost management productivity, moving from an experimental phase toward what it calls a more agentic approach, where software takes on real tasks rather than only answering questions.
Staff use the built-in Google Gemini features on Android for content creation, information access, and task optimization. B3 credits these features for a more agile and responsive way of working. If you are new to this shift toward AI that acts on your behalf, our explainer on full-stack AI breaks down what agentic AI really means.
The financial case is just as strong. B3 projects cost savings of around 30 percent over the next decade by choosing Android. Those savings do more than trim a budget line. They let the company run more frequent refresh cycles, keeping employees on brand-new hardware rather than aging devices.
| The Standout The 30 percent projected saving over ten years is the number that will catch any executive’s eye. It reframes a security and productivity upgrade as something that also pays for itself, and then funds the next upgrade. |
What B3’s Rollout Teaches Other Businesses
B3’s experience offers a clear playbook for any organization weighing a similar move, especially in regulated industries.
- Test before you commit. B3 benchmarked both ecosystems thoroughly before deciding, so its choice rested on evidence rather than habit.
- Automate the rollout. Zero-touch enrollment removed the biggest bottleneck, turning a months-long project into a two-week one.
- Treat security as layers. No single feature does the job. Hardware encryption, sandboxing, AI detection, and app controls work together.
- Count the ten-year cost. The real savings and productivity gains show up over the full device lifecycle, not just at purchase.
For a wider view of how Google is weaving AI across its platforms, including the enterprise tools B3 relies on, our recap of the latest Google AI updates covers the bigger picture.
The B3 Android Enterprise rollout shows that strong security and a modern, productive workforce are not opposing goals. A heavily regulated stock exchange put 1,000 secure devices into service in under two weeks. In doing so, it tightened its compliance posture, gave employees better hardware, and set itself up to save money for a decade.
For any business that thinks locking things down means slowing people down, B3’s story is a useful counterexample. With the right platform and a smart rollout, security, productivity, and cost control can all move in the same direction.
