Prompt Security: Israeli Startup Revolutionizes Generative AI Protection for Enterprises

Prompt Security is an Israeli startup that offers generative AI security for enterprises. The firm raised $18 million in a Series A funding round led by Jump Capital, just ten months after raising $5 million in a Seed round of funding.

The alarming reality of AI security is underscored by Gartner’s findings that nearly 30% of AI-adopting enterprises have experienced breaches. Prompt Security’s research further exposes the extent of the problem, revealing that the average enterprise uses 67 GenAI tools, many of which are deployed without proper authorization and trained on sensitive company data. This alarming trend highlights the urgent need for robust AI security measures to protect enterprises from significant risks.

Founded in 2023 by CEO Golan and CTO Lior Drihem, Prompt Security enables enterprises to benefit from the adoption of Generative AI while protecting from the full range of risks to their applications, employees and customers. At every touchpoint of Generative AI in an organization — from AI tools used by employees to GenAI integrations in customer-facing products — Prompt inspects each prompt and model response to prevent the exposure of sensitive data, block harmful content, and secure against GenAI-specific attacks. The solution also provides leadership of enterprises with complete visibility and governance over the AI tools used within their organization.
