Onyx Security, an Israeli startup focused on managing AI agents in enterprise settings, raises $113 million in a Series B funding round. The round is led by Bessemer Venture Partners and reportedly values the company at about $640 million, according to Calcalist as cited by The Next Web. SecurityWeek reports the Series B brings Onyx’s total funding to $153 million. Across the coverage, the central theme is governance: Onyx aims to keep a “human in the loop” so that people can approve or block what AI agents do inside organizations. The investments also suggest growing demand from enterprises for controls as AI systems take on more operational tasks. The Next Web notes the timing of the round, stating it follows Onyx’s prior activity by roughly four months, though it does not provide additional operational details in the excerpt. Neither source, in the provided text, describes specific customers, product features, or regulatory arrangements beyond the stated goal of maintaining human oversight.
