WEB CLIENT ACCESS

Every protocol. One browser tab. Zero install.

The 12Port web client renders RDP, SSH, VNC, Telnet, PowerShell, HTTPS web consoles, Kubernetes, and network appliance sessions inside a standard browser. No native client. No agent on the endpoint. Same zero-trust controls as the native proxies.

WHAT IT IS

A unified console, rendered in HTML5.

The 12Port proprietary web client lets users browse assets, request access, and launch sessions from a single browser interface. Every protocol renders as HTML5: full Windows desktop, Linux shell, network-appliance CLI, IBM PC5250 terminal, web-portal browsing, and more.

Mouse, keyboard, and clipboard pass through with policy. File transfers can be permitted, blocked, or scanned per role and target. Two admins can join the same session for real-time training, troubleshooting, or oversight.

PROTOCOL COVERAGE

PowerShell

Windows PowerShell with full transcript capture

VNC

Cross-platform desktop sharing

Telnet

Legacy systems, OT gear, industrial controllers

IBM PC5250

IBM i terminal sessions inside the browser

BEST-FIT SCENARIOS

When to reach for the web client.

Vendors and contractors

Third parties get a URL, MFA, and a brokered session. No VPN, no jump host, no client install on their device. Their access expires when the engagement ends.

Locked-down endpoints

Workstations where you cannot install or update an RDP or SSH client. The browser is enough. Same controls, no help-desk ticket.

Live session sharing

A second admin joins a live session for real-time monitoring, on-the-job training, or shadowing during a sensitive change. Native clients cannot do this; the web client can.

Mixed protocol days

Bouncing between a Windows VM, a Linux box, a network switch, and an AWS console in the same hour. One tab, one credential prompt, one audit trail.

Auditors and compliance reviewers

Read-only access to recordings and reports, with no software install on the auditor’s machine. Easy to grant, easy to revoke.

Break-glass and ad-hoc access

Late-night incident, on a personal laptop, with the corporate device offline. Browse to the portal, MFA, get to the host. No detour through IT.

CONTROLS BUILT IN

The same zero-trust layer.

Credential injection

The user never sees the password, key, or certificate. 12Port injects on the way to the target.

Session sharing

A second admin joins a live session for training, oversight, or incident response. Browser-only capability.

File and clipboard policy

Allow, block, or scan file transfers and clipboard contents per role and per target. Every attempt is captured.

Video recording

Full session video with embedded metadata. Playback in the same browser, exportable for compliance.

Approval workflows

High-sensitivity targets require approval before access. Decisions are recorded and tied to the session.

Session intelligence

Live behavioral analysis can alert, prompt for re-auth, or terminate a session automatically.

TRADE-OFFS

When native may fit better.

Browser sessions are excellent for everyday use, but a few jobs are still better suited to native clients: automation with Ansible or AI agents, SSH tunneling for databases, mobile RDP and SSH apps, and admins who lean heavily on power-user keyboard shortcuts in PuTTY, MobaXterm, or SecureCRT.

12Port runs both. Mix and match per user, per role, per target. See native client access →

Try it in a browser tab.

Spin up 12Port, browse to the portal, and launch an RDP or SSH session in a single tab.
