SOVEREIGN UNIFIED COMMUNICATIONS

Communications you own. Comms that can’t go dark.

Bulwark Voice Suite keeps your voice, video, messaging and emergency alerts on your own servers, inside your walls — encrypted, self-hosted, and running even when the internet or the cloud goes down. Your primary system where the cloud can’t reach; your resilient layer everywhere else.

Keep Teams for everyday chat — Bulwark runs the comms you can’t afford to lose, on servers you own.

Deploy it your way

Sovereign by default. Connected when you want it.

YOUR RESILIENT LAYER
Keep Teams. Add Bulwark underneath.
Keep Teams, Slack or your PBX for everyday work. Bulwark carries the mission-critical voice, video and emergency alerts that have to survive an outage, a cyberattack or an audit — on your own servers, with zero rip-and-replace.
YOUR PRIMARY SYSTEM
Where the cloud can’t reach.
In air-gapped, sovereign and remote sites — defence, classified, ships, field operations — cloud tools simply can’t run. There, Bulwark is your entire communications backbone: voice, video, messaging and alerts, fully offline.
Start underneath, grow into primary. Begin with the comms that must never go dark, then promote Bulwark to your main system whenever you’re ready — flat, capacity-based licensing means no per-seat tax caps how far it spreads.
ON THE ROADMAP Connected mode. Optional instant-messaging and presence bridging with Microsoft Teams, Webex and Slack for connected sites — so your sovereign comms reach people where they already work. Voice, video, recordings and emergency alerts always stay on your own servers.

Sovereign — and here’s what that actually buys you

“On your own servers” isn’t the point. These five outcomes are.

No per-seat tax
One flat, capacity-based licence — scale to thousands of users without the bill climbing every time you hire, and no surprise renewal hikes.
Passes the audit
Calls, recordings and data sit physically in your building and in-country — meeting data-residency and compliance rules a public cloud simply can’t.
Nobody can cut you off
You own the software and the servers. No vendor can suspend your account, change the terms, or price-gouge you at renewal.
No third-party breach surface
Your call content never sits in someone else’s cloud waiting to be leaked, subpoenaed or mined. Encrypted on every call.
Works with no internet
Offline-first by design. Lose the link or the cloud and voice, video and emergency alerts keep running — air-gap-ready from first boot.

Prove it in one day

No rip-and-replace. No access to your core infrastructure. Just proof.

ONE-DAY PILOT

Give us one day and one isolated segment.

We stand up a live Bulwark node on an isolated network segment — with zero access to your production systems — and prove total offline survival: calls, video and emergency alerts running with the internet physically pulled. At the end of the day, you keep it or we tear it down.

One isolated VLAN
A single segment we agree on — nothing touches production.
Zero core access
No credentials, no inbound paths into your infrastructure.
Internet pulled, live
We cut the link in front of you and the calls keep flowing.
Keep it or wipe it
Your call at the end of the day — no lock-in, no residue.
