The principal's phone number is the attack surface.
Mia Relay is a verified-identity communications channel that cold-contact attackers can't reach. Every connection is invited. Every user verified at the door. Principal, team, advance party and intel providers, on one network they control.
Signal protects the message. Mia Relay verifies the messenger.
Phone numbers leak, get sold, get spoofed. End-to-end encryption protects content against interception — it does not stop a stranger from reaching the principal in the first place. For a close-protection brief, "first contact" IS the attack.
Cold contact stops at the door
No one can ring or message the principal without an explicit invitation. There is no public number to dial, no email to spoof, no QR-code lure to try.
Identity is verified, not assumed
Every user passes a verification step before they can call or message anyone. Pretexting attacks — "your driver here, change of plan" — lose their oxygen when there is no anonymous account to spin up.
Cross-organisation by design
Team, advance party, residence staff, intel providers and law-enforcement liaison can all sit on the same network without being in the same tenant. Teams and Slack make external chat painful; Mia Relay assumes it.
Built for the real shape of a protective brief.
Principal ↔ close-protection team
One channel for the brief, location updates, route changes, residency arrangements. Voice and message, both verified, both auditable on the team side.
Advance teams + recces
Pre-deployment intelligence, venue assessments, alternate-route checks shared between teams without exposing the principal's number to a venue contact or hotelier.
Residence and household staff
Domestic staff, drivers, security cleared to receive operational messages without ever holding the principal's personal number. Access is invited, revocable, and per-individual.
Intel providers + analysts
External intelligence suppliers and risk analysts reach the operations lead, not the principal. Cross-organisation contacts on a verified network, not a WhatsApp group with a bunch of unknowns.
Law-enforcement liaison
A single, traceable channel between the protection lead and police, royal protection, or host-country liaison. No personal phone numbers exchanged; no SMS audit trail to subpoena from a carrier.
Crisis comms
When the principal needs to reach a pre-defined list immediately — family, legal, medical, security — that list is on one verified network, not scattered across phones, apps and assistants.
Cloud, dedicated, or in your own datacentre.
Most EP firms run on Mia Relay's dedicated cloud (UK South or EU West, single-tenant, no commingled data). Higher-sensitivity briefs run on a self-hosted or BYOC deployment inside the customer's own tenancy. Source-review access available to enterprise customers.
