Generative AI security startup Prompt Security on Wednesday announced raising $18 million in Series A funding, which brings the total raised by the company to $23 million.
The new funding round was led by Jump Capital, with additional support from Hetz Ventures, Ridge Ventures, Okta, and F5.
The Tel Aviv, Israel-based firm emerged from stealth mode in January, aiming to prevent employees from inadvertently exposing sensitive information to gen-AI tools and to secure AI deployments.
According to Prompt, its platform can secure AI across an organization’s touchpoints such as browsers, copilots, coding assistants, and homegrown applications, enabling them to use gen-AI safely, without risking data privacy and security.
The company scans prompts and model responses to detect and block data leaks and harmful content, and protects organizations from AI-specific risks, including jailbreaks, prompt injections, and shadow AI.
Prompt says its own customer research has revealed that the average organization uses over 60 gen-AI tools, most of which are not properly licensed or even approved. Roughly 39% of these tools, the company says, are trained on enterprises’ own data, potentially leading to policy violations.
By offering visibility, governance, and policy enforcement over AI tools, Prompt seeks to protect organizations’ applications, employees, and customers, and to enable businesses to safely adopt gen-AI.
“As enterprises accelerate their adoption of GenAI, so do the associated risks. This funding supercharges our mission to enable the safe use and deployment of GenAI in enterprises by mitigating such risks,” Prompt Security co-founder and CEO Itamar Golan said.
