What is Terniion?

Terniion is the secure network access control platform for teams done pretending "detect and respond" is a strategy.

No inbound connections. No public IPs. No scannable endpoints.

Process-to-process tunnels isolate every connection, so malware and lateral movement are non-factors.

Outbound-only connectivity and triple-layer, quantum-resistant encryption keep your network unreachable from the outside—and fast for the people and apps you actually like.

Achieves true zero trust protection

Zero Trust. Sounds great in board decks, then stalls under complexity and policy sprawl.
Terniion shrinks your attack surface to "undiscoverable" without ripping out what you already own.

  • Expose nothing: Outbound-only connections and no public IPs make your environment undetectable to scanners and drive-bys.

  • Stop lateral movement: Process-to-process tunnels keep compromises contained.

  • Future-ready encryption: Triple-layer, quantum-resistant protection dodges "harvest now, decrypt later" nightmares.

How Terniion fits your stack

You've invested in firewalls, identity, observability, and a bag of "must-haves." Terniion makes them all look smarter.

  • Overlay, not overhaul: Deploy in 90 minutes, start with high-risk apps, expand at your pace with no re-architecture.

  • Works everywhere: On-prem, cloud, hybrid, containers, edge. If it speaks IP, Terniion wraps it.

  • Less firefighting: No open inbound ports, fewer brittle exceptions. Your team does real work instead of babysitting access.

SealedTunnel

The patented data plane: triple-encrypted, outbound-only, process-to-process tunnels for every connection. Makes resources non-addressable and microsegmented at the process level so network exposure becomes a non-issue.

Aclave Authentication Management

No user names or passwords ever again. Integrated authentication for teams fixing identity and network exposure together. Lightweight, FIDO2-compliant, completely credential-less.

Paired with SealedTunnel, Aclave gives you end-to-end control from "who are you?" to "what can you reach?"

STLink

Connects outbound-only connections across clouds, data centers, and regions. Turns messy access rules into clean, scalable policies maintainable past the next re-org.

Connector

Runs close to workloads and handles the plumbing.
Establishes outbound-only connections, discovers apps you onboard, makes them reachable without open ports.

Commander

The control plane of Terniion where you have total visibility of all tunnels allowing the team to orchestrate management of the Terniion system seamlessly.
