Hala Systems develops solutions for civilian and asset protection, accountability, and the prevention of violence. Sentry, Hala's indication and warning system, generates real-time situational awareness of threats in the toughest places on Earth. Sentry Syria, Hala's early warning system for airstrikes against civilians in Syria, has saved hundreds of lives and prevented thousands of injuries. According to a preliminary assessment, the system reduced the lethality of airstrikes by around 20-30 percent in areas under heavy bombardment in 2018. Insight, Hala’s real-time analysis portal, provides an interface to data from its sensors, human observers, and strategic partners, along with information from open media. Data is hashed on the Ethereum blockchain, acting as a transparent ledger for data integrity. Hala Systems aims to reduce harm, increase security, and stabilize communities.
