The company makes the lofty promise that its products "stop mass shootings." According to a 2018 report on Gabriel published in the Jerusalem Post, there were an estimated 475,000 such "soft targets" across the U.S., meaning that "the potential market for Gabriel is huge."

Gabriel, since its founding, has been backed by "an impressive group of leaders," mainly "former leaders of Mossad, Shin Bet [Israel's domestic intelligence agency], FBI and CIA." In recent years, even more former leaders of Israeli and American intelligence agencies have found their way onto Gabriel's advisory board and have promoted the company's products.

While the adoption of its surveillance technology was slower than expected in the United States, that dramatically changed last year, when an "anonymous philanthropist" gave the company $1 million to begin installing its products throughout schools, houses of worship and community centers throughout the country. That same "philanthropist" has promised to recruit others to match his donation, with the ultimate goal of installing Gabriel's system in "every single synagogue, school and campus community in the country."
