MisterShell

Keep your terminal. Lose the sprawl.

Point the client you already like at MisterShell and work exactly as you do today — while the team finally gets one place that decides who may reach what, and keeps the record.

The MisterShell terminal workspace in an SSH client — resource tree, session tabs, and AI assistance alongside a live device session
Your own SSH client, with the resource tree, tabs and in-session AI — and the same policy as the browser

The same reach, under one enforced policy

MisterShell delivers the same reach — SSH, RDP, VNC, kubectl, database and cloud shells — behind one enforced policy, from the browser with nothing to install, or from the SSH client already on your machine. Point it at MisterShell and you get a full terminal workspace: the resource tree you would have browsed in the browser, several sessions open in tabs, and the same AI alongside the one you are working in — with the same permissions, policy, approvals and recording either way. Your automation takes the same door, so Ansible and the tooling around it keep reaching devices through MisterShell instead of around it — no playbook rewrite, and the same record as a session someone opened by hand. Every session is recordable and replayable by policy — immutable operational evidence in an object store you own — with every policy decision logged per rule and recorded sessions tied to the person behind them, credentials stored centrally instead of scattered across laptops — and a personal and team vault for each person’s own logins, with history and audit, so the KeePass file on a share can finally retire. Host keys are verified once against a saved fingerprint instead of a trust prompt on every laptop, and sensitive targets can sit behind an approval gate. And because sessions reach resources through outbound-only workers, a target only ever accepts connections from a known worker — you can close management ports to everything else, and no engineer’s laptop touches the resource directly. Connection profiles, access rules, audit, health, configuration history, and in-session AI all live in one self-hosted place. Files work the same way: instead of each engineer running SFTP from a laptop, your location tree doubles as a file catalog with object stores mounted per location, so a file for a Paris resource sits in a French bucket without anyone deciding that in the moment. People move files against the catalog and a policy governs every copy onto a resource — and because the closest worker streams the bytes, the device never reaches the store and the transfer keeps running after you close the tab. You keep one pane for everything; your organization gets the control — and the tight ingress — a local client cannot provide.

Where it breaks down on a team

The difficulty was never the client itself — it is that each one connects straight to the target, and that creates two problems the moment a team shares infrastructure. First, governance: hosts, keys, and credentials live in each person’s install — or their private cloud sync — so there is no chokepoint deciding who may reach which target, no recording of what was done, and no shared audit trail. Second, network exposure: because a client can connect from any laptop on any network, you cannot put a tight ingress rule in front of a resource — the target has to accept connections from wherever engineers happen to be, so management ports stay broadly reachable or guarded by a tangle of VPN and firewall exceptions. “Team” features push configuration out to clients; they never give the client a gate to pass through. That gate is the piece MisterShell adds, and it is the only part of the habit that has to change.

What MisterShell covers

The essentials, in one platform

Remote workers, enterprise sign-in, high availability, and audit export to your SIEM come with the Pro edition; policy engines, session recording, and automation ship with Enterprise; IDS, syslog collection, and external access are licensed add-ons.

Access surfaces — SSH, AWS CLI, Azure CLI, Kubernetes (kubectl), databases (PostgreSQL, MySQL, MariaDB, SQL Server, ClickHouse), interactive RDP, VNC, and web-application sessions — in the browser, or from your own SSH client against the same policy.
Your own SSH client & automation — Point your usual SSH client at MisterShell, sign in with your own SSH key, and work the way you already do — every shell resource you may reach, under the same permissions, policy, approvals and recording as the browser. A full terminal workspace comes with it: the resource tree, several sessions in tabs, and the same in-session AI, without leaving the terminal. Automation connects the same way, so Ansible and the tooling around it keep reaching devices through MisterShell rather than around it. Included in every edition.
Session policy & per-command control — Firewall-style allow/deny rules — with notify and log flags — at connection time (by location, resource type, tag, role, session type) and per-command ACLs that take a command line apart and require every part of it to be allowed — so a blocked command chained onto a permitted one still never reaches the target. An Approve action on a rule holds the connection until a person says yes.
Approval before access — Session and file-transfer rules can require a human decision before access — the roles you name approve, the access expires on its own, and every request and decision is kept as evidence even after the rule is edited or removed.
Governed file transfer — The location tree doubles as a file catalog, with object stores mounted per location — so where a file lives follows your topology. People move files against the catalog, never the resource directly; an ordered File Transfer Policy decides each copy on location, type, tag, role, direction and both paths — and can require an approval before the transfer starts. The closest worker streams the bytes, so the resource never reaches the store and no new egress path is opened. Every transfer is its own session, with operations and hashes recorded and no file content retained.
Credential storage & vaulting — Encrypted service account credentials with shared or per-user mapping, masked in the UI, plus a personal and team vault for each person’s own logins — shared by role, with history and an audit record of every use — replacing the KeePass file on a share. Rotation and secrets lifecycle stay in your existing secrets system, driven through the REST API or the official Terraform provider; MisterShell does not replace your secrets management.
Session recording & replay — Full recording and replay for terminal sessions and graphical RDP, VNC and web-app sessions — immutable operational evidence in an object store you own (local, S3, or Azure Blob), SHA-256 hashed at capture and verified on replay, with retention set per rule and replay flagging any gaps.
Audit export (syslog/CEF, webhook, Splunk HEC) — Security, policy, API, and AI audit streams exported to your SIEM over syslog/CEF or webhook (JSON or Splunk HEC) — the AI stream carries metadata only, never captured input or output — backed by a policy log of every rule decision and recorded-session timelines.

When a local client still earns its place

A local client — PuTTY, MobaXterm, SecureCRT, Royal TS, Devolutions RDM — still earns its place. It works offline, it costs little or nothing, and it needs no server behind it, so for a laptop that has to reach a lab or a home network on its own it remains the simpler answer. For rich graphical work — multi-monitor remote desktops, mapped drives — a native RDP client goes further than any browser or terminal session does. MisterShell does not ask you to give any of that up: your client stays, and it simply gains a governed way in for the infrastructure your team shares.

Start with MisterShell when

  • More than one person reaches the same infrastructure and you need central policy, recording, and audit
  • Your engineers should keep the terminal they like — and reach everything through one governed door
  • Ansible and your other automation should run under the same rules as the people, not beside them
  • You want to end credential sprawl and per-laptop configuration drift
  • Files moving on and off infrastructure should be policy-governed and logged, not an SFTP tab on each laptop
  • You also want health, configuration history, and AI in the same place

Keep a local client when

  • You work offline, or reach labs and home networks that sit behind nothing at all
  • Multi-monitor remote desktops and mapped drives are part of the daily job
  • There is no team-wide governance, recording, or audit requirement
  • You want a free or one-time-cost tool with no server component
