Why Cyphra

Not a generalist. A specialist.

Philippine-Specific

GCash, GlobeOne, Smart, PLDT, Converge — built for the Philippine telco ecosystem from the start, not adapted from foreign tools.

Working Prototype in 7 Days

Production deployment within 2 weeks. No scoping calls that go nowhere, no 3-month timelines for a portal.

Hardware + Software

Firmware, GPIO wiring, portal frontend, backend API, and cloud dashboard — one contractor, full stack, no handoff gaps.

Zero-Touch Fleet Management

Push updates to every device silently, remotely, over-the-air. Your operators never need to physically touch a router again.

Production Hardened

Encrypted firmware, tamper detection, self-healing watchdogs, hardware license binding — not an afterthought, baked in from day one.

Direct Access

You talk to the engineer who writes the code. No project managers, no account reps, no ticket queues. One message and we move.
