What does Prompt Security do?

Prompt Security is a comprehensive AI security platform designed specifically to protect organizations from the unique risks introduced by generative AI and large language models. It provides real-time protection against threats like prompt injection, data leakage, and malicious content generation across all AI touchpoints within an enterprise. The platform acts as a security layer that sits between users and AI models, analyzing and filtering interactions to prevent attacks while maintaining AI functionality.

The platform stands out by offering protection at multiple levels: securing employee AI usage to prevent shadow AI risks, safeguarding homegrown AI applications from vulnerabilities, protecting AI code assistants from exposing sensitive information, and providing specialized security for agentic AI systems through its MCP Gateway. What makes Prompt Security particularly valuable is its LLM-agnostic approach—it works with any AI model or service—and its seamless integration into existing tech stacks with both cloud and self-hosted deployment options.

This tool is essential for organizations that are actively deploying AI solutions but need to maintain security and compliance standards. Enterprise security teams, AI application developers, and CISOs benefit most from Prompt Security's capabilities, using it to secure customer-facing AI services, protect internal AI-powered applications, and monitor employee AI tool usage across the organization. The platform's expertise is backed by its involvement with OWASP's AI security research, giving it credibility in addressing the most current AI security challenges.
