When PuTTY is enough
Keep PuTTY if you open one host, close the window, and never maintain an inventory. It is free, tiny, and honest about what it is. Switching for switching's sake is wasted effort.
When you need a PuTTY alternative
Switch when any of these are true:
- Sessions live in the registry or scattered .ppk files with no real vault
- You also need SFTP, tunnels, notes, or the same hosts on Mac or Linux
- You run the same command across many boxes (fleet Ops)
- You want AI agents (Cursor / Claude) to use SSH only after you Approve each command
What iLead adds on top of an SSH client
- Encrypted local vault (Argon2id + AES-256-GCM) for hosts, keys, notes, and tunnels
- Import PuTTY sessions instead of retyping every host
- Built-in SFTP, Database Studio, and multi-hop bastions
- Optional local SSH MCP for Cursor and Claude Code

Migrate without a cloud account
Import PuTTY (and MobaXterm / WinSCP / ~/.ssh/config) into the vault, verify host keys on first connect, then optionally sync the vault file through a folder you already use. Guide: import PuTTY sessions.
FAQ
What is the best PuTTY alternative in 2026?
If you need only one disposable Windows session, PuTTY is still fine. If you need a cross-platform encrypted inventory, SFTP, fleet Ops, and optional MCP, choose a local-first SSH manager such as iLead rather than a mandatory cloud suite.
Can I import PuTTY sessions into iLead?
Yes. Use the PuTTY importer, preview the list, commit into the encrypted vault, then confirm host keys on first connect.
Is there a PuTTY alternative with an encrypted vault?
iLead seals hosts, keys, notes, and tunnels in one local vault file. There is no vendor cloud copy of your host list.
Does iLead replace PSFTP?
For most workflows yes: SFTP lives in the same vault as the terminal, with inline edit and transfers, so you are not juggling a separate CLI tool for every host.
