Sasquatch vs Microsoft Sentinel

Run your SIEM
in any cloud you own.

Cut compute and storage by more than 80% — losslessly, in the cloud you already own.

Microsoft Sentinel meters you per GB on commit tiers and runs only in Azure, keeping your security data in Microsoft's cloud. Sasquatch delivers the same detection coverage losslessly in the cloud you already operate — AWS, GCP, or Azure.

100 GB / day of security logs (~3 TB/mo) · annual list · every figure traces to a published rate.

And a fraction of the total Microsoft Sentinel bill — lossless, in the cloud you already own.

01Where the bill goes

One line item, not a meter stack.

The Microsoft Sentinel bill splits across a stack of separately metered line items. Sasquatch is one rate on the compressed bytes you keep — the same workload, a fraction of the footprint. Each block is a real line item; the length is its share.

02The meter stack

One rate. Ingest tiers + retention + Copilot.

The same workload, two monthly statements. One is a single line you can forecast to the byte; the other is a stack of meters, each on its own unit, re-negotiated at every renewal.

03The compression

3 TB in. 20 GB out.

The full bar is the raw workload. The fill is what actually survives to disk after each product compresses it — shorter is cheaper to store, forever.

Where each tool wins.

Sasquatch ships 3,700+ detections out of the box, MITRE ATT&CK-mapped, with UEBA, threat intel, voice, and agentic AI investigation, all on lossless retention in your own cloud. The incumbents meter you per GB-day or per-MPS and keep your data in theirs.
