Industries
We know how each operation really works.
Every industry has its own bottlenecks, regulations and pace. We arrive speaking your language, with solutions already proven in the field.
Connectivity where fiber doesn't reach.
We bring networks to remote rural properties so production and animal health data reach headquarters in real time.
Challenges
- Farms hundreds of kilometers from the capital
- No carrier infrastructure
- Equipment exposed to the weather
We deliver
- Antenna and link installation
- Bench pre-configured equipment

How we work
One method, from assessment to operation.
Every project follows the same four stages, with clear deliverables and one technical lead from start to finish.
01
Assessment
Site visit, environment survey and risk map. You receive a report with priorities.
02
Architecture
Solution design, equipment list, schedule and budget, approved before any work begins.
03
Deployment
Equipment pre-configured and bench-tested at our Ibirité base before it reaches your site.
04
Operation
Monitoring, support and continuous improvement, with documentation delivered and kept up to date.

Security alert
Phishing aimed at companies: how to spot it
Scams by email, text message and WhatsApp are more convincing and often target finance and leadership.
- Open systems by typing the official address, never through links you receive
- Be wary of urgent payment requests or changes to PIX keys
- Confirm through another channel before granting access or releasing money
- Turn on two-factor authentication for critical accounts
NR-1
Regulation
Psychosocial risks join occupational risk management
Brazil's NR-1 now includes psychosocial factors in companies' occupational risk management.
- Identify factors such as overload, targets and harassment by department
- Record assessments and action plans with owners and deadlines
- Track indicators over time, not only in one-off surveys
- Keep evidence for inspections and audits
Wi·Fi
Guide
LGPD-compliant guest Wi-Fi
Offering internet to customers and visitors requires care with the data collected at sign-up.
- Ask only for what you need: name and tax ID or phone
- Record consent at the moment of sign-up
- Separate the guest network from the corporate network
- Store connection logs with restricted access
Careers
