Prompt Security: From Startup to $250M Exit

Prompt Security, a startup focused on generative AI security, has been acquired by SentinelOne for an estimated $250 million. Founded in August 2023 by Itamar Golan and Lior Drihem, the company rapidly addressed the growing threat landscape of AI applications. Their platform offered comprehensive GenAI security, including shadow AI discovery, data sanitization, and prompt injection defense.

The company's rapid success is underscored by the escalating costs of AI-related security breaches, with shadow AI alone costing enterprises $4.63 million per incident. This acquisition reflects the critical need for robust AI security measures as businesses increasingly adopt AI technologies without adequate safeguards.

Golan's strategic decisions, such as building a category-defining platform rather than a feature-based solution and prioritizing enterprise complexity from the outset, were key to Prompt Security's accelerated growth. The acquisition by SentinelOne is expected to extend AI security capabilities across its broader platform.
