A short assessment shows you exactly where your Microsoft exposure sits, before you commit to anything.
Response, engineering, and cost. One team.
Analyst-led, not alert-led
Certified analysts investigate before anything reaches you. Every incident carries a human verdict, written evidence, and a named owner.
Response with committed actions
Containment is pre-agreed, not improvised. Session and token revocation, device isolation, account disable, process kill, Conditional Access block.

Verified on GoodFirms
We tried to deploy Microsoft Sentinel ourselves and spent 9 months drowning in alerts and spiralling costs. Falconer optimised our deployment in 3 weeks. Costs down 64%, false positives down 80%, and we caught a PHI access attempt in the first month that our old setup would have missed.
