We build secure communications for the day the network is attacked
Irythra Systems Private Limited is an Indian defence technology company. We build communications for contested spectrum that remove what adversaries target (the key on the device, the single link and the box at the boundary) instead of hardening it.

How we work
Removed, not hardened
When an attack works structurally, we take away its target rather than adding another layer of protection around it.
Volunteered, not extracted
What is real, what is a stub and what would prove us wrong are published. A vendor who cannot say where their architecture hurts has not looked.
Users first, HQ second
A signals regiment user trial produces the evidence that makes the staff case. Everything we build is designed to be tested in one.
The constraint is the strategy
Software-first with one piece of hardware keeps the capital requirement and the audit surface small.
Why software-first wins here
One piece of silicon
The hardware surface is a single root of trust held by the customer. In Indian defence procurement that is a sovereignty argument before it is a cost one.
Runs on issued kit
Quorum Lace runs on ruggedised COTS already in service, with existing radios as bearers.
Overlay, not rip-out
Adoption does not require replacing a radio fleet, which is what kills most defence communications sales.
Capital-light
Reaching a field trial costs engineers and time, not tooling and inventory. Failure is survivable and iteration is fast.
The honest trade: a software-first stack is easier to clone, and Sigilcore adds a hardware line item with a lead time and a supply chain to defend. We accept both. The moat is accreditation and trust, not source code.
iDEX is the door, DAP Chapter III is the room
- iDEX challenges. Secure communications is a standing problem category for the Services, Coast Guard and Defence Space Agency.
- From prototype to procurement. Successful iDEX prototypes are procurable under DAP Chapter III without a fresh open tender, which compresses development to induction.
- Users first. A signals regiment user trial is the first milestone that matters.
| Beachhead | Why first |
|---|---|
| Corps of Signals: dismounted trial | Feels the capture and EMCON problems most directly; smallest integration surface. |
| UAS units | No radio replacement needed; provenance is an unmet audit requirement. |
| CAPFs / Coast Guard | Real contested-communications need; faster procurement cycles. |
| Friendly states | The same software once India-proven, subject to export licensing. |
The binding constraint is a signals regiment willing to run a trial.
Not capital. If you can open that door, or want the architecture note and the runnable prototype to take apart yourself, we would like to hear from you.
