Tool Introduction

Prompt Security launched in January 2024 to tackle the growing security risks created by widespread generative AI use in enterprises. Founded by cybersecurity veterans Itamar Golan and Lior Drihem, the company focuses on threats unique to AI tools, such as prompt injections and data leaks. Prompt Security highlights that many organizations use unapproved AI tools—a challenge known as "Shadow AI"—which introduces major governance and compliance concerns. The platform builds on its team's work with the OWASP Top 10 for Large Language Model (LLM) Applications, offering deep insight into emerging AI-specific vulnerabilities.

Detailed Overview

Enterprise-grade protection for all generative AI interactions—preventing data leaks, misuse, and compliance failures at scale.

What Prompt Security Does

Prompt Security inspects user prompts and AI-generated responses across an enterprise’s full AI footprint. It uses semantic analysis to detect sensitive content like personal health or financial data—even when obfuscated. The platform blocks prompt injections and jailbreaking attempts that aim to bypass safety rules. You can deploy it via browser extensions, SDKs, APIs, or on-premises setups. Content filters screen responses for harmful language or copyright risks before distribution.

Who Prompt Security is for

Prompt Security supports CISOs, IT leaders, developers, compliance officers, and security teams in large organizations using generative AI. Teams gain visibility into unmonitored AI tool usage. Developers can integrate secure AI features in products without risk exposure. Compliance professionals ensure alignment with regulations while enabling broader innovation through safe adoption of generative tools.

Top Differentiators

Prompt Security is purpose-built for generative AI threats—not retrofitted from legacy tools. Its LLM-agnostic design detects risky behavior across thousands of different platforms based on real usage patterns. The company’s OWASP contribution brings advanced knowledge of emerging threats. Flexible deployment options—including SDKs and browser add-ons—make integration easy across diverse tech stacks.
