ActiveFence

ActiveFence is a trust and safety technology company founded in 2018, headquartered in New York, with significant R&D operations in Israel. The company builds infrastructure that helps online platforms detect and remove harmful content — including terrorist content, child sexual abuse material (CSAM), disinformation, and coordinated inauthentic behavior — before it spreads at scale.

ActiveFence's core product is a threat intelligence and content moderation platform sold to online platforms, social networks, and marketplaces. The company's model centers on proactive threat detection: rather than waiting for users to flag harmful content, ActiveFence continuously monitors the open, deep, and dark web to identify emerging threats and bad-actor tactics, then delivers that intelligence to platform trust and safety teams. Its primary buyers are trust and safety professionals and policy teams at large consumer internet platforms. The company is sales-led and targets enterprise-scale platform customers.

ActiveFence offers a platform that combines automated threat detection with human analyst expertise. The system ingests signals from across the web to build profiles of harmful campaigns and actors, enabling platforms to act on threats proactively rather than reactively. The company has positioned its offering around coverage of a wide range of harms — including violent extremism, synthetic media abuse, and platform manipulation — served through a single integration point for platform partners.

ActiveFence maintains a substantial R&D center in Israel, which serves as its primary engineering hub. The company's technical founding team has roots in Israeli intelligence and cybersecurity, a background that is central to its threat-intelligence methodology. The Israel office focuses on research, engineering, and analyst functions.
