Security & trust

Trust you can check.

We’d rather give you evidence than assurances. Here’s what has been independently reviewed and where that review stops, what we commit to by design, and how to tell us when something’s wrong.

By design

What we commit to.

Properties of how the technology is built — not certifications. Particle CS holds none. For the mechanisms behind these commitments, see Technology.

You hold your keys

Particle CS doesn’t custody assets or key material for your account.

Nothing until it’s granted

Roles, operations and targets that weren’t permitted are refused — an allowlist the contract enforces.

Rules outlive our software

Policy is enforced by the account, not our application. Another client can’t skip it.

Separation of duties

Sensitive operations can require more than one party — over time, or across roles.

Evidence stays with the operation

Who proposed, approved or cancelled, and what ran, is part of chain history — not a chat log.

Open to inspection

The Protocol’s contracts, tests and audit report are public.

Responsible disclosure

Found a vulnerability? Tell us privately.

Please don’t open a public GitHub issue. Email us with a description, steps to reproduce and the potential impact — we’d rather hear about it before anyone else does.

Running a security review?

Architecture reviews and vendor questionnaires included — we’d rather answer before a contract than after.
