Secure from the ground up — Microsoft 365 management that stays on your device
Most ways to manage many Microsoft 365 tenants route your customers through a third-party cloud with standing delegated admin over every tenant. EasySwitch365 takes the opposite approach: it’s a local desktop app. Each customer runs in its own OS-encrypted, isolated session on your device — no vendor cloud holding your data, no central token vault to breach, no password store. A smaller attack surface, by design.

More than switching — a command center for Microsoft 365
EasySwitch365 is a command center for Microsoft 365 that runs entirely on your machine. Every customer is a fully isolated session, with a built-in PowerShell 7 console, an AI assistant that turns plain language into the right command, a searchable knowledge base, the admin portals as in-app tabs, and an optional PIN / Touch ID lock — all without sending your customers’ data to anyone else’s cloud.

The hidden risk of cloud multi-tenant platforms
Cloud multi-tenant management and governance suites are powerful — but to work, they usually hold standing delegated admin (GDAP) or broad app permissions across all your customer tenants, processed in their cloud. That concentration is exactly what attackers want: compromise the platform or its tokens once, and every tenant you manage is exposed at the same time. For many MSPs, handing a third party permanent admin to every customer is a bigger risk than the problem it solves.
How EasySwitch365 is secure by architecture
Local-first, no third-party cloud
Everything runs on the admin's device. Your customers' sessions and data never pass through a vendor's cloud, so there's no central store to breach.
No standing delegated admin
No GDAP or broad app registration across every tenant. You sign in per tenant, interactively or by device code, only when you work in it — no permanent cross-tenant keys.
Encrypted by the OS
Each tenant's session is an isolated browser partition, encrypted by the operating system (Keychain / DPAPI) and bound to your user account.
Data minimization, no password vault
Only names and domains are stored — never passwords. The AI assistant sends just your request and the tenant domain, no customer data.
Custom portals — URLs only, no passwords
Store any extra third-party portals per customer — PBX, time tracking, backup, ticketing — and only the URLs are saved on your device, never the passwords. Each opens inside that customer’s OS-encrypted, isolated session, so you sign in once and stay signed in, and no sign-in ever crosses tenants.
FIDO2 / passkey sign-in, unchanged
EasySwitch365 has no authentication of its own — you sign in through Microsoft’s real page inside the isolated session. If your tenant enforces FIDO2, a passkey or a hardware security key, it applies here exactly as it would in a browser. Nothing is bypassed, and no passwords are ever stored.
Hardened against token theft
Signed-in sessions are OS-encrypted, isolated per customer and never exported. Combine that with Microsoft Entra Token Protection / Conditional Access (device-bound tokens) and a stolen session token is worthless on any other machine.
You decide how long a session lives
Per customer, choose to not persist the sign-in at all — nothing is written to disk — or wipe a customer’s cookies, tokens and cache anytime with one click. Session lifetime is yours to control, tenant by tenant.
Local app vs. cloud governance platform
| Cloud multi-tenant platform | EasySwitch365 | |
|---|---|---|
| Where data & tokens live | The vendor's cloud | Your device, OS-encrypted |
| Access model | Standing delegated admin across all tenants | Per-tenant sign-in, only when you work in it |
| Attack surface | One breach can expose every customer | Local; no central cross-tenant token vault |
| Third-party portal logins | Often a shared credential vault in the cloud | No passwords stored — only the URL; opens in the tenant's isolated session |
| Best for | Bulk policy & compliance at scale | Fast, secure day-to-day work |
Governance platforms have their place for bulk compliance. This is about a different, smaller-attack-surface architecture for everyday multi-tenant work.
FAQ
Is EasySwitch365 a cloud platform?
No — it's a local desktop app for Windows and macOS. Each tenant runs in its own OS-encrypted session on your device; there's no third-party cloud collecting your customers' data. The one exception is the optional AI assistant — off by default; you activate it explicitly and it sends your input to a cloud AI provider.
Does it need delegated admin (GDAP) across all my tenants?
No standing delegated admin or broad app registration. You sign in per tenant with the normal interactive or device-code flow, only when you work in it — no central token vault.
Where is my customers' data stored?
On your device, encrypted by the OS (Keychain / DPAPI). Only names and domains are stored, never passwords. Nothing goes to a third-party cloud.
