Trust & security

What we hold, what we're working on, and who else touches your data.

This page is what we'd send to a procurement team on day one. No "compliance theatre", no certifications we haven't earned, no sub-processors we don't disclose.

Security posture

The shape of the surface.

Encryption in transit

TLS 1.3 on every public endpoint. HSTS enabled. HTTP/2 + WebSocket for the realtime hub.

Encryption at rest

Azure storage service encryption (AES-256) on SQL and Blob. Customer-managed keys available on Business + Enterprise.

End-to-end

Private direct messages are end-to-end encrypted by default. Group calls run on LiveKit SFU; voice and video are E2EE-capable on the roadmap.

Identity

ASP.NET Core Identity with PBKDF2 + per-user salt. JWT access tokens with a stable signing key on production; refresh-token rotation.

SSO & provisioning

Business + Enterprise: Entra ID, Okta, Google Workspace via OIDC. SCIM 2.0 provisioning. Per-tenant claim mapping.

Audit

Login, message, call and admin actions logged. Business + Enterprise: JSON export to customer-controlled storage. Retention configurable.

Certifications

Honest status, not a roadmap with no dates.

We don't list certifications we don't currently hold as "held". We do list the ones we're actively working towards, with our honest estimate of where we are. Ask us for the audit evidence at any point.

Reporting issues

Vulnerability disclosure.

We treat security reports as a priority and we don't litigate good-faith research. Email security@miabazo.com with a description, proof-of-concept and any reproduction steps. We'll acknowledge within one working day.

Please don't access data that isn't yours, don't degrade service for other customers, and give us reasonable time to fix before public disclosure.
