SentinelOne has agreed to acquire Prompt Security to enhance its AI-native Singularity Platform, aiming to secure generative and agentic AI tools in enterprise environments. The integration will provide organizations with real-time visibility into AI usage, control over data sharing, and automated policies to prevent security risks, such as prompt injection and sensitive data exposure.
Prompt Security’s solutions provide immediate insight into GenAI deployments, help manage employee use of AI tools such as ChatGPT and Gemini, and reduce shadow AI risk—all while maintaining oversight. Combining SentinelOne’s endpoint and cloud security with Prompt Security’s platform delivers full-spectrum AI protection across infrastructure and user interaction.
Prompt Security’s technology integrates with browsers, desktop applications, and APIs to ensure real-time risk mitigation, complementing SentinelOne’s existing products by forming a unified layer for GenAI security.
After the acquisition, SentinelOne customers will gain:
— Real-time visibility into AI usage and data practices.
— Policy-based controls for safe AI use and data protection.
— Advanced AI threat prevention.
— Model-agnostic coverage for major LLMs and self-hosted models.
— Security across 13,000+ MCP servers.
This move strengthens SentinelOne’s position in enterprise cybersecurity, broadening protections from endpoints to GenAI and agentic AI. It continues SentinelOne’s tradition of fast threat detection and advanced AI integration, now further empowering security teams and employees to adopt AI securely.
