Values

The three non-negotiables

Every engineering decision goes through these three filters.

01

Transparency

A three-dimensional cube graphic against a solid black background

No black boxes

Every primitive ships with its full spec and verifier. It doesn't count if not reproduced

02

Speed

Milliseconds, always

Seals happen at the edge in under 8ms. anything slower is a regression.

Integrity

A network diagram consisting of seven smaller cubes arranged in a hexagonal, interconnected structure.

The ledger doesn't lie

Every seal is anchored to a merkle log. Tamper attempts are mathematically detectable.

Team

Built by the ones who know

A small group of cryptographers, runtime engineers, and edge-protocol veterans. Every one of them has built — and broken — production systems at scale.

Everything you need to know, answered.

Latency, data exposure, compliance, cost. self-hosting. We answer the hard ones here without the marketing language. If something is missing, the spec is public.

01

Does sentinel add latency to my llm calls?

02

Does sentinel see my prompts or responses?

03

What happens if sentinel goes down?

04

Is this compliant with hipaa, soc 2, and gdpr?

05

How is this different from just logging my llm calls?

06

What does a seal actually contain?

The proof layer your
stack is missing

Sentinel seals every prompt, every response, every inference. Ship AI with the same confidence you ship code.
