“Not verified” means the reviewed public vendor sources did not confirm the capability. It does not establish that the capability is absent from a private offer or later release.

SUPERWISE Sentinel is a focused AI gateway for protecting requests before they reach an AI provider. Prompt Security, now part of SentinelOne, documents a broader platform spanning AI usage control for employees and developers, agent and MCP governance, and red teaming and runtime protection for the AI apps a team builds. The stronger fit depends on which traffic and endpoints need coverage. For keeping customer data out of ChatGPT from a Windows PC, see the guide, Stop customer data reaching ChatGPT from a Windows PC.

Sentinel replaces email addresses, phone numbers, Social Security numbers in the 123-45-6789 format, credit card numbers, IBANs, IP and MAC addresses, full-length OpenAI keys, and AWS secret keys when labeled. Bank account numbers, tax IDs and EINs, national IDs, VINs, dates of birth, and medical record numbers are replaced only in the labeled formats the gateway recognizes. The admin chooses whether Sentinel redacts or blocks, and sets the replacement text.

When Prompt Security is the better fit

  • You need discovery and policy across employee and developer AI use in browsers, desktop apps, and embedded copilots, unsanctioned tools included. [P2] Read 2026-10-10
  • You need governance for AI agents and MCP servers, with discovery, risk scoring, access policy, and a searchable log of agent actions. [P3] Read 2026-10-10
  • You need one vendor for employee AI controls and for red teaming and runtime protection of the AI apps you build, inside the SentinelOne Singularity Platform. [P1] Read 2026-10-10 [P4] Read 2026-10-10

When Sentinel fits

  • You need a focused gateway for requests from a supported Windows setup or an application configured to use the Sentinel CLI proxy. [S2] Read 2026-10-07 [S3] Read 2026-10-07
  • Sentinel replaces identifiers such as email addresses, phone numbers, credit card numbers, and API keys before a prompt leaves. [S4] Read 2026-10-07 [S5] Read 2026-10-07
