5buyer types

Verdict by buyer type

regulated financial: Neither separates itself on published approval and audit detail. Microsoft Sentinel documents permissions and rule expiry but no approval gate or per-action record; Prophet Security previews remediation and takes only approved actions, but describes no audit record. Ask both for the control documentation in writing.
lean team: Microsoft Sentinel is easier to size up before a call: it publishes pay-as-you-go and commitment pricing, with playbook runs billed separately. Prophet Security offers a free proof of value but publishes no price.
MSSP: Neither Microsoft Sentinel nor Prophet Security states MSSP terms on the pages read. Ask both for multitenant approval settings and per-client audit exports.
Microsoft estate: Both name Microsoft pieces. Microsoft Sentinel is the Microsoft SIEM itself and takes Defender XDR incidents as triggers; Prophet Security names Microsoft Sentinel and Entra ID among its integrations.
CrowdStrike estate: Only Prophet Security says anything specific: it names CrowdStrike Falcon Next-Gen SIEM among its integrations. Microsoft Sentinel states no CrowdStrike-specific detail on the pages read.

When to pick each

Pick Microsoft Sentinel when you need to see a price or a pricing unit before a sales call, because it publishes pay-as-you-go and commitment tiers from 100 GB to 50,000 GB a day, with playbooks billed separately as Logic Apps.

Pick Prophet Security when deployment location and data handling are fixed by policy, because it states dedicated single-tenant deployment with a bring-your-own-key option, without regions or retention.
