SUPERWISE Sentinel vs Prompt Security: features and alternatives

Reviewed 2026-10-06 · Update owner: Jason Metzner

SUPERWISE® Sentinel is a focused AI gateway for protecting requests before they reach an AI provider. Prompt Security documents a broader platform spanning browser and endpoint controls, application gateway deployment, MCP governance, shadow-AI discovery, and red teaming. The stronger fit depends on which traffic and endpoints need coverage.
