Oasis Security raises $120 million Series B to secure the rise of AI agents
The Israeli startup targets growing risks as machine identities vastly outnumber humans across enterprises.
Cybersecurity startup Oasis Security has raised $120 million in a Series B funding round led by Craft Ventures, with participation from existing investors Cyberstarts, Sequoia Capital, and Accel. The new capital brings the company’s total funding to $195 million.
Founded in 2022 by Danny Brickman and Amit Zimerman, Oasis develops what it calls “agentic access management,” a framework designed for a computing environment where machine identities vastly outnumber human users. According to data cited by Palo Alto Networks, machine identities now outnumber humans by a ratio of 82 to 1.

That imbalance exposes a structural limitation in existing security systems, which were largely built to govern human access. As organizations deploy AI agents more widely, the number of systems requesting access to sensitive infrastructure is expanding rapidly, often in ways that are difficult to track.
Oasis argues that this shift requires a rethinking of access control itself. Its platform is designed to grant permissions dynamically, based on what a system is attempting to do in real time, rather than relying on standing permissions or predefined roles. The company describes this as “just-in-time” and “intent-based” access, aimed at limiting exposure by granting only the minimum permissions necessary for a given task.
“Cybersecurity is defined by how we protect against abnormal and risky events. In the era of AI, that definition is being reshaped by access,” said CEO Danny Brickman. “Every organization deploying AI agents is taking on access risks they can’t yet see.”
Over the past year, the company says it has seen strong enterprise uptake, with new annual recurring revenue growing fivefold. Its customer base is concentrated among large organizations, with a majority of clients drawn from the Fortune 500. Much of that growth has come through multi-year contracts, suggesting that its technology is being embedded into core identity and access infrastructure rather than deployed as a peripheral tool.
