CJIS-aligned encryption for LTE PTToC: what agencies need to verify
Encryption, identity, audit and physical-security requirements to confirm before deploying LTE PTToC in a CJIS-scoped environment.
CJIS compliance isn't a checkbox on a platform; it's a shared responsibility between the agency, the platform vendor and the carrier. This guide walks through the layers to verify before a PTToC deployment can be considered CJIS-aligned.
Encryption in transit and at rest
Voice, messaging and location must use AES-256 end-to-end. Storage (recordings, logs, media attachments) must be encrypted at rest with managed key rotation. ip³PTT meets both by default.
Identity and access
SSO with MFA, role-based access controls, and per-device certificate provisioning are table stakes. Agency admins should be able to remotely revoke a device, wipe cached media and rotate keys.
Audit and logging
Full audit trails for talkgroup membership changes, admin actions, key rotations and dispatch console access are required for CJIS-scoped operations. Log retention must match your agency's policy.
Physical and carrier layers
Verify carrier and platform SOC 2 / ISO 27001 posture, data-center physical controls, and any subprocessors handling voice or metadata. Multi-carrier eSIM does not weaken this posture as long as the platform terminates encryption end-to-end above the carrier layer.
