Hala Systems develops advanced solutions for civilian and asset protection, accountability, and the prevention of violence. Sentry is Hala's indication and warning system that utilizes a multi-sensor network to generate real-time situational awareness of threats in the toughest places on Earth. For instance, Sentry Syria is Hala's early warning system for airstrikes against civilians in Syria. Analysis indicates that it reaches up to 2.1 million people, has saved hundreds of lives, and has prevented thousands of injuries. According to a preliminary assessment by Hala, the system reduced the lethality of airstrikes by an estimated 20-30 percent in several areas under heavy bombardment in 2018. Hala's second product, Insight, is a real-time analysis portal providing an interface to data from Hala's sensors, human observers, and strategic partners, along with information from open media. Data is hashed on the Ethereum blockchain, which acts as a transparent ledger for data integrity. Through innovative technology, we aim to reduce harm, increase security, and stabilize communities.
