About
The infrastructure behind operations that cannot fail.
STSH Software is a technology company focused on three lines: white-label platform for telecom providers, managed cybersecurity for enterprises, and consumer protection software sold through an authorized channel.
Manifesto
"Built for Critical Systems."
Some software stops and life goes on. Some software stops and no invoice goes out, no attack gets detected, no user gets answered, no TV signal arrives, no phone call connects.
That's the software STSH builds.
Every line of code, every architectural decision, every SOC shift, and every SLA written into a contract answers a single question: what would happen if this stopped working right now?
We work so that question never has to be answered.
Three lines
One company, three distinct operations, one engineering practice.
01 / B2B INFRASTRUCTURE
STSH Platform
White-label platform for ISPs and integrators. Billing, VoIP, MVNO, IPTV, and premium apps in a single contract.
02 / B2B SECURITY
STSH Security
Managed cybersecurity with 24/7 SOC, proprietary SIEM, pentest, compliance, and incident response.
03 / B2B CONSUMER
STSH FortiSafe
Offline consumer-protection software, sold exclusively through an authorized partner channel.
Leadership
An operation led by someone who has been operating for more than two decades.
