Prompt Security Secures $18M in Series A Funding

Prompt Security, a leader in Generative AI (GenAI) Security, has announced the successful closure of an $18 million Series A funding round. The investment was led by Jump Capital, with participation from Hetz Ventures, Ridge Ventures, and tech giants Okta and F5 12.

Addressing the Growing Risks of Generative AI

Founded in 2023 and launched in January 2024, Prompt Security aims to tackle the increasing security challenges posed by the rapid adoption of generative AI in enterprises. According to Gartner's AI in the Enterprise Survey, nearly 30% of enterprises deploying AI have experienced an AI security breach 2.

Prompt Security's research reveals alarming statistics:

  • The average enterprise uses 67 GenAI tools
  • Almost 90% of these tools lack proper licensing or corporate approval
  • 39% of these tools are configured to train on enterprises' own data, potentially violating policies involving sensitive intellectual property 2

Comprehensive Security Solutions

Prompt Security's platform offers a range of security measures to protect enterprises from AI-related risks:

  1. Inspection of prompts and model responses
  2. Prevention of data leaks
  3. Blocking of harmful content
  4. Defense against GenAI-specific threats such as prompt injections and shadow AI
  5. Full visibility and governance over AI tools in use 1

The company's solutions cover various AI touchpoints within organizations, including browsers, copilots, coding assistants, and custom applications 1.

Notable Achievements and Growth

Since emerging from stealth in January, Prompt Security has made significant strides:

  • Quadrupled its revenue
  • Grew its customer base fivefold, including Fortune 500 companies
  • Introduced the first security and governance solution for Microsoft 365 Copilot 12

Expert Leadership

Prompt Security's founding team brings extensive experience in cybersecurity and AI:

  • Itamar Golan (Co-founder and CEO): Established AI divisions at Check Point Software Technologies and Orca Security, and was part of the core team of OWASP's Top 10 for LLM Applications
  • Lior Drihem (Co-founder and CTO): 18 years at Check Point Software Technologies, rising to Director of Innovation 12

Industry Perspectives

Saurabh Sharma, Partner at Jump Capital, emphasized the critical need for Prompt Security's solutions in today's rapidly evolving AI landscape. Richard Moore, Security Director at 10x Banking, highlighted the importance of balancing innovation with security and regulatory compliance in the adoption of generative AI 2.

As enterprises continue to accelerate their adoption of generative AI, Prompt Security aims to play a crucial role in enabling safe deployment and mitigating associated risks. The new funding will support the company's mission to advance its solutions and expand its presence across different industries and geographical regions 12.
