Cost Optimization

Orphaned Resources

Stop paying for resources nobody is using. StratoLens finds unattached disks, unused public IPs, idle services, and other waste across your environment, and shows you the cost impact of each one so you can prioritize cleanup.

StratoLens is a self-hosted Azure visibility platform. It runs in your own tenant; your infrastructure data never leaves it.

The Problem

Every Azure environment has forgotten resources quietly running up the bill:

Leftover Disks and IPs: When VMs get deleted, their disks and public IPs often stick around, still incurring charges
Idle Services: Expensive resources like Azure Bastion may have zero connections for weeks
Hard to Find Manually: Checking for waste across dozens of subscriptions and resource types is tedious and easy to miss
No Context: You find an unattached disk or public IP, but you have no idea what it used to belong to or whether it's safe to delete

The Solution

Get a clear list of what's costing you money and delivering no value:

Broad Detection: Finds unattached disks, unused public IPs, orphaned NICs, and more
Usage-Based Analysis: Flags idle resources like Azure Bastion with no connections over a configurable timeframe
Cost Impact Per Resource: See exactly how much each orphaned resource is costing you, so you clean up the expensive ones first
Historical Context: Snapshot history shows what each orphaned resource used to be attached to and when it was last connected. No more guessing whether that public IP is safe to delete.

Inside Orphaned Resources

StratoLens orphaned resources list sorted by cost impact, led by an expensive unattached premium managed disk among unused IPs and idle services — The orphaned resources view for the Contoso Financial demo environment sorted by monthly cost, with a large premium disk detached from a long-deleted database VM sitting at the top of the pile. Shown with demo-environment data.

Historical context for an unattached disk showing which VM it used to belong to and when it was detached, so deleting it is a decision instead of a guess.

Idle Azure Bastion hosts flagged by usage analysis after weeks with zero connections, still billing every hour.

Unused public IP addresses left behind by deleted infrastructure, each with its individual cost impact listed.
