RasnuOS vs Teleport & Bastion SSH
Teleport and SSH bastions get you a terminal prompt, then leave you typing raw commands by hand. RasnuOS pairs zero-SSH outbound access, RBAC, and tamper-evident audit trails with an AI operations engineer.
Don't just proxy raw root shells—govern and automate the actual work.
RasnuOS eliminates inbound SSH ports via an outbound-only agent, provides an instant browser terminal and visual file/process explorer, and layers on per-command guardrails, Approval Cards, and AI incident remediation.
Teleport records video of an engineer accidentally breaking production. RasnuOS blocks destructive commands before they run.
Onboard any server in 30 seconds without maintaining proxy/auth cluster infrastructure or client CLI versions.
Get browser terminal, file manager, 15-second health monitoring, staged fleet rollouts, and AI troubleshooting in one platform.
Fixing a Production Issue via Teleport / Bastion
Manual Shell ProxyAn engineer requests access to db-replica-03 via Slack/Teleport Access Requests.
A manager approves *blanket shell access* to the host—without knowing which specific commands the engineer is about to run.
Once inside the root shell, there are no command-level guardrails or automatic config backups.
The engineer has to manually dig through logs, edit config files in vim, and restart services across five nodes one by one.
Compliance auditors later get a raw terminal keystroke replay that is painful to search or correlate with change tickets.
Fixing the Same Issue with RasnuOS
Command-Level GovernanceThe engineer asks RasnuOS to diagnose db-replica-03. Read-only diagnostics run safely without granting root shell access.
RasnuOS proposes the exact config diff and service reload on a structured Approval Card with a rollback plan.
An Admin (or ServiceNow approval webhook) approves the *exact command and file diff*—not a blank check for root access.
Our cloud safety checks and host-level guardrails verify the payload before executing and taking an automatic file backup.
The prompt, diff, approver identity, and command output are sealed into the tamper-evident audit log.
Side-by-Side Capability Breakdown
| Capability | RasnuOS | Teleport & Bastion SSH |
|---|---|---|
| Zero Inbound Firewall Ports | ✓ Outbound-only connection over port 443 (close port 22 completely) | ✓ Teleport reverse tunnels allow closing inbound port 22 (Bastions do not) |
| Granularity of Approvals | ✓ Per-command & per-file-diff Approval Cards with rollback plans | ✗ Session-level access approval (grants broad shell access once approved) |
| Destructive Command Prevention | ✓ Cloud command safety checks + built-in OS guardrails inside the host agent | ✗ Engineers with root shell access can still run rm -rf or mkfs |
| Built-In AI SRE & Triage | ✓ Investigates logs, metrics & processes automatically and drafts fixes | ✗ None—engineers must manually debug every server via CLI |
| Multi-Server Fleet Orchestration | ✓ Coordinated staged rollouts across dozens of nodes with health checks | ✗ Designed for single-host interactive sessions |
| Visual Node & Process Explorer | ✓ Browser terminal + visual file browser (with diff/undo) + live process manager | Partial — Browser SSH terminal only; no visual file diff or process manager |
| Team & ServiceNow Approvals | ✓ Built-in ServiceNow & team approval links for risky changes | Partial — Enterprise tier access plugins for session requests only |
| Audit Trail Format | ✓ Structured, searchable tamper-evident audit log per command | Partial — Terminal session recordings & eBPF events |
| Continuous Health Monitoring | ✓ 15-second CPU, memory, disk & systemd monitoring with AI AutoPilot | ✗ Access proxy only—no infrastructure health monitoring |
| Setup & Maintenance Overhead | ✓ 30-second single binary install; zero cluster infrastructure to manage | ✗ High—requires managing Auth/Proxy servers, certificates & tsh clients |
Least-privilege execution instead of blanket shell access
The biggest security gap in bastion hosts and access proxies is that once an engineer is granted a session, they hold an unrestricted shell. RasnuOS lets your team resolve 95% of infrastructure tasks without ever opening an unrestricted root shell:
- Role-Based Access Control: Let junior engineers or developers run read-only AI diagnostics as
Vieweror propose fixes asOperator, while requiring anAdminorOwnerto click Approve on high-risk changes. - Interactive Browser Terminal Included: When you genuinely need an interactive shell, RasnuOS includes a built-in live browser terminal, visual file manager, and process explorer—with zero SSH keys on laptops.
- Auditable Change Management: Every approved command links directly to the AI reasoning, risk score, approver user ID, and stdout result in a tamper-evident audit log.
Identity-aware proxy for internal web apps & desktop RDP
Teleport has evolved into a broad workforce identity proxy covering internal web applications, Kubernetes APIs, Postgres wire-protocol proxying, and Windows Desktop RDP sessions.
- Workforce SSO Proxy: If your primary requirement is replacing a corporate VPN so 500 employees can access internal Jira/Grafana web apps and database wire protocols via Okta OIDC certificates, Teleport is built for that.
- Complementary Layers: Teams use Teleport for employee SSO access to internal web dashboards while deploying RasnuOS to operate, monitor, and self-heal the underlying Linux, macOS, and Windows server fleet.
Technical Architecture for Security & Platform Engineers
rasnuos-agent dials outbound over HTTPS (port 443) with TLS certificate pinning and per-server token authentication. You can drop 0.0.0.0/0 on port 22 across every firewall and security group.
