Prompt Security
Prompt Security was an Israeli cybersecurity company that built a runtime security and governance layer for generative and agentic AI in the enterprise. Its platform inspected prompts and model responses in real time to provide visibility, policy enforcement, data-loss protection, and defense against AI-specific attacks; it is now part of SentinelOne following the 2025 acquisition.

Products & Services
Enterprise platform for securing employee-facing AI tools and internally developed AI applications through real-time prompt/response inspection, visibility, governance, policy enforcement, sensitive-data protection, harmful-content blocking, and AI-attack prevention.
Managed-service offering enabling MSSPs to deliver generative-AI security and governance to their customers.
Authorization capabilities designed to control AI access to enterprise data and strengthen data-access governance.
Open-source AGPL collection of signed security skills and advisory intelligence for AI-agent runtimes. It supports drift detection, live recommendations, automated audits, skill-integrity verification, and approval-gated installs across OpenClaw, NanoClaw, Hermes, and Picoclaw.
Market Position
Prompt Security positioned itself as an enterprise AI-security platform spanning both employee-facing AI usage and internally built AI applications, rather than only an AI application scanner or model-security tool. Its differentiation included real-time controls at the prompt/response layer, shadow-AI visibility, Copilot coverage, protection against AI-native attacks, and governance for agentic and MCP workflows. Comparable competitors include Lakera, HiddenLayer, Robust Intelligence, Protect AI, CalypsoAI, and Cisco/Panoptica-style AI security offerings.

Founding Story
Golan and Drihem founded Prompt Security in August 2023 after seeing enterprise adoption of ChatGPT and other generative-AI tools outpace existing security controls. Their initial vision was to give organizations real-time visibility and governance over AI interactions while preventing sensitive-data exposure, harmful content, prompt injection, jailbreaks, and other AI-native risks.
