Zero Trust SSH
Reach any host through the agent's outbound tunnel — port 22 stays closed to the world. Every connection is verified, scoped and time-boxed before a shell is ever granted.
Install one agent and give your team secure SSH to any host — without opening a single inbound port or handing out credentials. Every session is recorded and replayable, every action is governed by RBAC, and live CPU, RAM, disk, process and network metrics stream straight to your console.

Platform
Subnomic replaces bastions, VPNs and shared SSH keys with one secure agent — and streams full server telemetry while it's at it.
Reach any host through the agent's outbound tunnel — port 22 stays closed to the world. Every connection is verified, scoped and time-boxed before a shell is ever granted.
Every SSH session is captured keystroke-by-keystroke and replayable like a video. Search, scrub and review exactly what happened — perfect for audits and incident response.
Map users to hosts and actions with least privilege. Decide who can connect where, who can run what, and when access expires — all from one policy model.
Live telemetry from every host, with history and alerting out of the box. Know exactly what your fleet is doing the moment it happens.
A single self-updating binary you install once. It dials out over TLS and needs no inbound firewall changes — access and metrics, all from the same agent.
The same Zero Trust agent will soon let you inspect containers, exec into pods and roll deployments — all policy-checked and recorded, no kubeconfig or Docker socket exposed.
Identity
Stolen keys, shared passwords and forgotten access tokens cause most breaches. Subnomic removes them entirely. Strong cryptographic identity, privileges that expire on their own, and one model that establishes trusted interactions between humans, machines and AI agents.
Every human, machine and agent is bound to a hardware root of trust. There are no passwords, API keys or secrets to phish, leak or reuse — identity is proven by cryptography, not by what someone knows.
Access is granted just-in-time and expires automatically. With no standing privileges, there's nothing for an attacker to harvest and the lateral attack surface collapses toward zero.
The same identity and access model extends to AI agents and MCP tooling. Autonomous workloads get scoped, auditable, time-boxed access — never a long-lived key — so automation stays safe by default.
Risk reduced to zero by design. No open ports to scan. No credentials to steal. No standing access to escalate. What doesn't exist can't be breached.
How it works
No ports to open, no bastions to maintain. Install, and the host appears in your console with Zero Trust SSH and live metrics ready to go.
Run one command. The agent registers itself and dials out over TLS — no inbound ports.
CPU, RAM, disk, processes and network interfaces start flowing to your console instantly.
Open Zero Trust SSH sessions that are scoped by RBAC and recorded for replay — every time.

Control plane
policy + audit
The agent always initiates the connection. Attackers have no port to reach — even if they know your IP.
Security
Most breaches start with an exposed port or a leaked SSH key. Subnomic removes both. Access flows through the agent's outbound tunnel, scoped by policy and logged end to end.
No inbound ports. Nothing to port-scan, nothing to brute-force.
Full session recording. Replay any SSH or command session for audit and incident review.
Granular RBAC. Roles map users to hosts, namespaces and actions with least privilege.
Encrypted everywhere. TLS in transit, and a self-hostable control plane for full data ownership.
