Convergent Defense Foundation
Our purpose

We study what India's security forces need, then build it in India.

An independent non-profit serving India's public safety, defense and emergency response forces. Alongside the research we run an engineering team, so what we recommend we can also build.

TALON — Tactical Awareness, Location & Operations Network

An autonomous IoT mesh that detects wildlife and intruders in forests with no cellular coverage. Camera nodes relay images over a Wi-Fi HaLow mesh, and a separate LoRa channel carries SOS alerts and MAYDAY voice. Detections reach a command gateway in near real time, with nobody stationed at the node.

In February 2026 a five-node overnight trial with a state forest department in Uttarakhand transferred every image it captured.

Concept

Disaster-response comms kit

Portable mesh communications for teams operating where infrastructure has failed.

Prototype

TALON Edge device

GPS-enabled edge node with an integrated camera and IR night vision. It feeds event-triggered captures into the TALON mesh.

Prototype

Low-cost welfare sensing

Affordable environmental and safety sensing for under-served communities.

Research

Acoustic classification models

On-device models to distinguish threat sounds from ambient forest audio.
