“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.

LiteLLM is the right choice when a team wants to operate a developer gateway for model routing, spend tracking, and budgets. Sentinel replaces identifiers such as email addresses, phone numbers, credit card numbers, and API keys before a prompt leaves. Records metadata for every request: counts, which rule fired, latency. They solve different primary problems. For the wider category, read what an LLM gateway is and why one should remove personal data.

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.

Questions about LiteLLM and Sentinel

What is a LiteLLM alternative for data protection?

SUPERWISE Sentinel is an AI gateway for supported Windows, browser, CLI, and team traffic. Sentinel replaces identifiers such as email addresses, phone numbers, credit card numbers, and API keys before a prompt leaves. Records metadata for every request: counts, which rule fired, latency.

Can LiteLLM use Microsoft Presidio?

Yes. LiteLLM documents a Presidio guardrail that connects to Presidio Analyzer and Anonymizer services and can mask or block configured entity types.

Does LiteLLM replace SUPERWISE Sentinel?

The products address different primary jobs. LiteLLM documents model routing, load balancing, spend controls, and configurable guardrails. Sentinel documents data replacement and request logging across its supported employee and application paths.

Which product covers employee ChatGPT and Claude use?

Sentinel documents supported Windows and browser coverage. The reviewed LiteLLM documentation describes an API proxy and does not document direct desktop or browser session protection.

Limitations and boundaries

  • Sentinel is presented as a data-protection gateway, without LiteLLM's documented model routing, load balancing, spend tracking, and budget controls.
  • The reviewed LiteLLM documentation does not describe direct protection for ChatGPT or Claude desktop and browser sessions.
  • Prompt-level detection of API keys and other secrets was not verified in the reviewed LiteLLM documentation.
