Real activity, not assumptions
We rank licenses by actual sign-in activity — not just whether the account exists.
Microsoft 365 license intelligence
Stop paying for Microsoft 365 licenses no one uses.
TrosteLens scans your Microsoft 365 tenant, finds idle and over-licensed accounts, and shows you exactly how much you can save — every month, automatically.

See your waste, take action
Get a clear breakdown of inactive licensed users, with monthly cost projections you can act on today.
From "probably over-licensed" to a number.
The Microsoft admin center tells you a license is assigned. It won't tell you whether anyone's actually using it — so the waste stays invisible and the bill renews on autopilot.
TrosteLens ranks every license by real sign-in activity, then attaches a monthly cost to what it finds. Instead of a hunch, you get a list you can act on.
- Assigned
- A seat exists on the invoice. That's all the admin center can tell you.
- Actually used
- Sign-in activity, per user — the number your renewal should be based on.
$3,024 / month identified as reclaimable
$36,288 a year
- 84 inactive accounts still holding a license — no sign-in in 30+ days
Illustrative figures — your own numbers depend on your tenant. The monthly total is the count of inactive accounts at your configured cost per license.
Built for teams that hate guessing.
Multi-tenant ready
One workspace, many tenants. MSPs and IT consultancies can manage every client side-by-side.
Automated scheduling
Run scans on a schedule and get reports delivered before your monthly billing review.
Audit-friendly
Every scan, action, and admin change is logged so you can answer the question "who changed what, when?"
Managing Microsoft 365 for many clients? The waste is in every tenant.
Logging into each client tenant to check licenses one at a time isn't realistic — so the waste compounds across your whole book of business.
TrosteLens was multi-tenant from day one. One login holds all your clients side by side. Run a scan and get a client-ready savings report for each — ranked by real sign-in activity, with a dollar figure attached. It's the kind of thing that makes every QBR easier and every renewal stickier.
- One workspace, every client tenant — no separate logins.
- Client-ready savings reports you can put your name on.
- Automated scheduling so fresh reports land before each client's billing review.
Built on the access your team already trusts.
Connecting a tool to your Microsoft 365 tenant is a real decision. Here's exactly how TrosteLens handles it.
No passwords stored
You sign in with your existing Microsoft / Azure AD account — the same secure sign-in your team already uses.
Secure, read-focused connection
TrosteLens uses an on-behalf-of connection to Microsoft Graph to read the license and activity data it needs to find waste. Nothing more.
Full audit trail
Every scan and admin action is logged — who changed what, and when — so you always have an accountable record.

Questions, answered.
- Isn't this the same as what the Microsoft admin center shows me?
- No. The admin center shows which licenses are assigned. It doesn't show whether they're actually being used. TrosteLens ranks licenses by real sign-in activity, so you can see which assigned seats are dead weight.
- Do you store my credentials?
- No. You sign in with the Microsoft / Azure AD account your team already uses, and TrosteLens connects with a secure on-behalf-of flow to Microsoft Graph. No passwords are stored, and every action is audit-logged.
- How long does a scan take?
- Most scans finish in under a minute. There's no setup project — connect, scan, and see results.
- How does billing work?
- $3 per active user, per month, flat. The billing quantity auto-syncs to the users assigned to your tenant, so you never overpay. Start with a 14-day full-access trial — no credit card required. See full pricing details.
- What happens when my trial ends?
- Your account moves to read-only and your scan history is preserved. Subscribe whenever you're ready and pick up exactly where you left off.
- I'm an MSP — do I need a separate account for each client?
- No. One workspace holds all your client tenants side by side. TrosteLens was built multi-tenant from the start.
