Prompt Security

Prompt Security is an AI security platform, now part of SentinelOne, that gives organizations visibility and control over how generative AI is used across the business. It inspects prompts and responses as they flow between employees, applications and models, detects sensitive data leaving the organization, blocks prompt injection and enforces governance policies on which AI tools may be used and how. It is built for security teams and CISOs at enterprises adopting chat assistants, coding tools and autonomous agents. Core capabilities include monitoring of prompt activity across the organization, detection of exposed secrets and personal data, prompt injection defense, customer defined guardrails, topic detection and data protection filters. The company has extended the platform to agent security with two tools: OneClaw, which tracks and analyzes OpenClaw agent deployments, and ClawSec, a security skill suite for AI agents with drift detection, live recommendations, automated audits and skill integrity verification. Its Prompt Fuzzer is an open source tool for testing how a system prompt holds up against sixteen attack types across sixteen model providers. Pricing is not published. The site directs buyers to see the platform or book a demo through SentinelOne, and licensing is quoted through SentinelOne's sales channel. The SentinelOne acquisition is the fact to know. The product is branded Prompt Security from SentinelOne and its calls to action route to SentinelOne's site, so it is best evaluated as part of that platform rather than as a standalone vendor.
