Microsoft Sentinel India: one workspace, every connector
A 320-user Mumbai BFSI tenant ran Splunk, LogRhythm and three ad-hoc UEBA tools side by side. One Sentinel workspace replaced all four and saved Rs 87 lakh a year.
Microsoft Sentinel SIEM and SOAR at a glance
Why Microsoft Sentinel anchors most Indian siem and soar estates.
- What it is
- Microsoft Sentinel is a cloud-native SIEM and SOAR built on Azure. It ingests security telemetry from Microsoft 365, Entra ID, Defender, Intune, AWS, Google Cloud, on-premises servers, and 300-plus connectors into a single India region workspace, then runs analytics rules and Logic Apps playbooks to triage incidents.
- Licensing shape
- Pay-as-you-go ingest billed per GB per day, or a commitment-tier reservation that cuts the per-GB rate 40 to 65 percent past 100 GB a day. Microsoft 365, Entra ID, and Defender connectors ingest free in most tenants.
- The real cost driver
- It is rarely Sentinel ingest itself. The real spend most businesses find is the Splunk, LogRhythm, or QRadar licence and the ad-hoc UEBA tools running next to a workspace that could absorb all of it.
- Who it fits
- Indian businesses running 100 to 2,000 endpoints, already on Microsoft 365 with Defender or Entra ID Premium, facing a CERT-In incident-reporting obligation, a BFSI audit, or a DPDP-driven data residency requirement.
- India residency and DPDP
- The workspace pins to Central India or South India region, so the retained security log estate sits inside Microsoft India datacentres under the DPDP Act 2023 framework.
- Security layer
- Sentinel correlates Entra ID sign-in risk, Defender for Endpoint alerts, Intune device compliance, and Quantum Networks ZTNA access logs in one workspace instead of three separate consoles.
- Pricing shape
- Pay-as-you-go ingest from Rs 250 per GB per day. A 100 GB commitment-tier reservation runs about Rs 165 per GB, falling to Rs 145 per GB at the 500 GB tier. A Sirius Star managed SOC retainer runs from Rs 36,000 per tenant per month.
- The stakes
- A 320-user Mumbai BFSI tenant was running Splunk, LogRhythm, and three ad-hoc UEBA tools side by side. One Sentinel workspace with a 100 GB commitment-tier reservation and a managed SOC retainer replaced the lot and reclaimed Rs 87 lakh a year.

Microsoft Sentinel SIEM and SOAR vs Splunk, Sophos
All four are honest choices. Most Indian buyers land on the first option for service depth and ecosystem fit.
| Brand | Where it wins | Best fit |
|---|---|---|
| Microsoft Sentinel via Sirius Star | Wins the workspace whose source of truth is already Microsoft 365, Entra ID, Defender, and Intune. Free M365 connectors plus a commitment-tier reservation typically cut a Splunk licence 30 to 65 percent on a 320-user BFSI tenant. | Indian businesses standardised on Microsoft 365 that want one accountable partner running the SIEM and SOAR workspace. |
| Splunk | Wins the workspace with deep SPL muscle memory and custom apps that already pay for themselves. | Security teams with an existing Splunk investment and hybrid on-premises ingest patterns. |
| Sophos Intercept X and MDR | Wins the workspace whose pain is endpoint detection and managed response on heterogeneous hardware, not a full SIEM build. | Businesses that want endpoint MDR and XDR in one console rather than a workspace-and-connector project. |

Microsoft Sentinel SIEM and SOAR India FAQ
Common questions about this brand for Indian buyers. Hover any underlined term for a plain-English definition.
What is Microsoft Sentinel and when do Indian businesses need it?
Microsoft Sentinel is a cloud-native SIEM and SOAR built on Microsoft Azure that ingests security telemetry from Microsoft 365, Entra ID, Defender, Intune, AWS, Google Cloud, on-premises servers, and 300-plus connectors into a single India region workspace. Analytics rules, machine-learning detections, and Logic Apps playbooks then triage and contain incidents. Indian businesses need it the moment a CERT-In incident-reporting obligation, a DPDP audit, a cyber-insurance renewal, or a BFSI regulator audit asks for a unified, retained, India-resident security log estate and a documented analyst response.
What does Microsoft Sentinel cost in India in 2026?
Pay-as-you-go ingest sits around Rs 250 per GB per day in the Central India region. A 100 GB per day commitment-tier reservation lands around Rs 165 per GB, falling to Rs 145 per GB at the 500 GB tier. Microsoft 365 connectors, Entra ID sign-in logs, and Defender for Endpoint alerts ingest free in most tenants. A Sirius Star managed SOC retainer for a 320-user Indian tenant lands around Rs 36,000 per tenant per month including workspace operations, analytics rule tuning, and a quarterly posture review.
Microsoft Sentinel vs Splunk vs Sophos XDR, which fits an Indian security team?
Pick Microsoft Sentinel when the estate is already on Microsoft 365, Entra ID, Defender, and Intune, since the free M365 connectors plus commitment-tier reservations typically cut a Splunk licence below 30 percent. Pick Splunk when the security team has deep SPL muscle memory and the workspace already runs custom apps. Pick Sophos Intercept X and MDR when the endpoint footprint is the heavy lift and the team wants endpoint MDR and XDR in one console rather than a full SIEM and SOAR build. The honest call lands in the readiness review, not in a vendor brochure.
How long does Microsoft Sentinel deployment take in India?
Sirius Star ships a free readiness review inside one business day. Workspace creation, region pinning to Central India or South India, and the first batch of Microsoft 365, Entra ID, and Defender connectors land in 2 to 4 weeks for a 100 to 300-user tenant. The full analytics rule pack, UEBA tuning, Logic Apps SOAR playbooks, and the first incident triaged inside the managed SOC retainer take 6 to 20 weeks depending on hybrid AWS, Google Cloud, and on-premises connector breadth.
Does Microsoft Sentinel store Indian tenant data under DPDP?
Yes. The workspace can be pinned to Central India or South India region, so the retained security log estate sits inside Microsoft India datacentres under the DPDP Act 2023 framework. Sirius Star configures every workspace for DPDP residency by default and pairs Sentinel with Microsoft Purview for the DPDP audit-trail archive and Secure Data Guard for the DLP layer over the exported incident data.
Is Microsoft Sentinel the right fit, or should I stay on Splunk or Sophos XDR?
Microsoft Sentinel fits Indian businesses on Microsoft 365 with 100 or more endpoints, a CERT-In or BFSI reporting obligation, or a Splunk, LogRhythm, or QRadar licence past Rs 25 lakh a year. If your estate is under 50 M365 seats with no Defender for Endpoint and no compliance obligation, a Defender for Business standalone bundle is cheaper than a Sentinel workspace plus retainer. If your team already runs deep Splunk SPL custom apps and the migration cost outruns the licence saving, stay on Splunk. Sirius Star says so in the free review rather than selling a workspace you do not need.
The CISO wants fewer consoles. Finance wants the Splunk invoice gone.
