Public client

Three lines
One company, three distinct operations, one engineering practice.
Why STSH
Four pillars of critical operations.
Contractual SLA across every product
99.9% contractual uptime. No "best effort". Indicators tracked in a dedicated client dashboard.
In-house engineering, not resale
Proprietary platform and SIEM. Adaptation in hours, not in third-party vendor sprints.
Regional coverage: Brazil + Cono Sur
Operations distributed between Brazil and Paraguay. Support in Portuguese, Spanish, English, and Guaraní.
Senior team, decisions close at hand
Lean operation. The people who make technical decisions are the ones executing. No management layers between client and engineering.
