Prompt Security, an Israeli-based startup, is emerging from stealth mode to address the growing need for enhanced security in the rapidly advancing field of generative AI (GenAI). With businesses embracing generative AI technologies at an unprecedented pace, concerns around security have become more pronounced. Prompt Security aims to assist organizations in safeguarding their data from potential leaks to GenAI tools, including unauthorized ones often referred to as “shadow AI.”
Led by CEO Itamar Golan and CTO Lior Drihem, both with backgrounds at Check Point and Orca Security, Prompt Security has recently secured a $5 million seed round led by Hetz Ventures, with participation from Four Rivers and notable angel investors, including CISOs from Airbnb, Elastic, and Dolby.
Golan, reflecting on the genesis of Prompt Security, shared that the idea came about 18 months ago when his team at Orca began exploring AI-based remediation features. Recognizing the security gaps introduced by new architectures and frameworks, Golan and Drihem saw an opportunity to create a solution for this evolving market.
Prompt Security’s approach addresses the challenge faced by Chief Information Security Officers (CISOs) who often lack visibility into the tools accessed by users within their networks. This lack of insight creates a potential risk of data leakage, including personally identifiable information, which could lead to regulatory issues. To tackle this, Prompt Security offers a browser extension and IDE plugin that automatically detects patterns related to GenAI usage and enforces security policies, introducing minimal latency to the user experience.
On the application side, the company emphasizes the vulnerabilities introduced by GenAI chat apps, such as prompt injections and jailbreaks, which could enable attackers to run unauthorized code within a company’s network. Golan highlighted the company’s ambition to create a comprehensive platform addressing both corporate InfoSec and application security aspects of GenAI usage.
While CISOs were previously unaware or unconcerned about GenAI security, Prompt Security notes a shift in perception as shadow AI usage increases. Looking ahead, the startup plans to expand its services to help customers secure GenAI applications during the development and testing phases. Golan acknowledges the dynamic nature of the market and expects Prompt Security’s focus to evolve based on customer feedback and market trends.
