Autonomous
Drone Security
Protect military installations, critical establishments, government buildings and sensitive areas from all drone classes.
Comprehensive, networked drone security that can protect against areas upto 4000 sq.kms
12 modular technologies
Indrajaal stitches 12 proprietary technologies, which can be used in combinations with each other depending on the need
Networked architecture
Indrajaal’s hive-like network is modular, and repeatable over areas upto 4000 sq.kms
Protects against all drone classifications
Indrajaal counters all sizes of drones, from nano to large; and all levels of autonomous drones

Wide range of application
Indrajaal is a modular solution that protects military installations, critical industries, moving targets like convoys and large areas like the border
AI-powered
We use AI to analyse threats, and suggest mitigative actions. Indrajaal also uses AI to continuously learn and evolve against changing threats.
Built with decades of R&D
Indrajaal was built with the combined 15-year expertise of Grene Robotics, and three decades of expertise in radar and airspace management by ex-Airforce personnel

Indrajaal is the world’s only anti-drone system that can defend against all classifications and all levels of autonomous drones.

12 technologies. 1 autonomous solution.
We’ve stitched together 12 Indrajaal proprietary modular technologies that can be used separately, or in combination with each other to form an autonomous drone security solution
5-step fully autonomous process that keeps you safe
Why Indrajaal
Traditional systems can’t keep up with modern threats
Low RCS missiles
These aren’t detectable by traditional active radars
Autonomous UAVs
The pilot-less drones is the modern weapon of choice of weapon because there’s no human cost.
Swarm drones
When multiple drones attack, serial engagement systems don’t work. Only one has to get through to cause havoc.
Smart munitions
Precision-guided munitions, equipped with infrared and lasers are designed to seek out specific targets.
Indrajaal is a networked, modular solution that counters the limitations of traditional systems
Traditional Systems
Point defence system
Can intercept and neutralise threats of a smaller area, and only in close proximity
Only active RF detection
Active RF detection can’t detect low RCS missiles or drones operating in silent/stealth mode
Stand alone identification
Lack of centralized coordination results in missed opportunities for comprehensive threat assessment
Serial engagement
Potentially slower response times; not effective against drone swarms
Indrajaal
Wide area defence
Wide-area mesh network and modular architecture help protect a wide area
Multi spectral detection
Acoustic sensors, active RF, passive RF, ESM, EO, thermal sensors can detect all classes of drones
Central identification
24*7 autonomous monitoring through an integrated system enables autonomous, coordinated responses
Parallel engagement
Combination of counter drones, existing weapon integration, frequency jammers, etc, combine to enable quick response times against multiple parallel threats

Grene Robotics
We Deliver Autonomic Systems.
As organizations grow, traditional manual management cannot scale at the same rate. Autonomic systems are self-managing physical or software systems that learn from their environments. But unlike autonomous or automated systems, they can dynamically modify their own algorithm with no software updates. This allows rapid responses to change, enabling management at scale of complex environments.
We started Grene Robotics in 2008 to bring people, process, things and data into one unified platform that can be managed by an AI CEO. Our platform has replaced Salesforce, SAP and Oracle on multiple occasions.
We ventured into the defence space in 2021 with Indrajaal, the world’s first autonomous drone defence dome.
