Microsoft Sentinel for India compliance — DPDP, CERT-In, RBI and SEBI 2026
India's compliance landscape doesn't ask whether you have a SIEM — it asks whether you can prove what you detected, when, with timestamps and evidence chain. CERT-In's 6-hour reporting clock, DPDP Act ₹250 crore Schedule penalty, RBI 24×7 monitoring mandate, SEBI CSCRF — every one of these obligations starts at detection. Microsoft Sentinel is the data plane that closes the loop: cloud-native SIEM with 180-day log retention in Indian Azure regions, KQL-based detection content tuned to Microsoft Threat Intelligence, and seamless integration with E5 Security Defender stack. This post maps each Indian regulator's requirement to the Sentinel feature that satisfies it.

2 regions
Sentinel India residency
Azure Central India + South India — full ingest, processing, storage in-country.
The compliance trigger isn't the breach — it's the detection
CERT-In's 2022 Direction created a six-hour reporting clock that starts at the moment of awareness. DPDP Act 2023 created a Data Protection Board notification trigger keyed to "knowledge of the breach." RBI / SEBI / IRDAI sector frameworks all require continuous monitoring. None of these obligations work without a SIEM that actually detects.
Microsoft Sentinel is the data plane that detection runs on. Cloud-native, Azure-region-resident, KQL-based content, native integration with the rest of the Microsoft security stack (Defender XDR, Purview, Entra ID), bundling with E5 Security. For Indian regulated entities already on Microsoft 365, Sentinel is the natural SIEM choice.
The four regulators that touch SIEM
| Regulator / Standard | Core requirement | Sentinel feature that satisfies it |
|---|---|---|
| CERT-In (Direction 20(3)/2022) | 6-hour reporting; 180-day log retention in India; NPL/NIC NTP | Analytics tier 180-day retention + Azure India region + Analytics rules |
| DPDP Act (2023, Sec 8 + Schedule) | Reasonable safeguards; breach notification to Data Protection Board | Defender XDR + Sentinel incident timeline + automated playbooks |
| RBI Cyber Security (Jun 2016 + successor) | 24×7 monitoring SOC; baseline controls; Annual SAR | Sentinel + Ogma managed SOC; SAR-aligned content packs |
| SEBI CSCRF (2024) | 24×7 SOC for market intermediaries by category | Sentinel + connectors for market-infrastructure logs |
| IRDAI ICS Guidelines | Web app + endpoint monitoring; log retention | Sentinel + Defender for Cloud + Defender for Endpoint |
Sentinel India residency — the data path
Azure region matters
Provision Sentinel workspaces in Azure Central India or South India
Sentinel runs on a Log Analytics workspace, which is a regional resource. When you create the workspace in Central India or South India, every byte of log data — ingestion, processing, indexing, retention — stays inside that Azure India region. No cross-region replication unless you explicitly enable it.
For CERT-In's "within Indian jurisdiction" rule, this is non-negotiable. For DPDP residency comfort, this is the cleanest demonstration. For RBI / SEBI audit, the workspace region is visible in the Azure portal — directly auditable.
The 180-day log retention math
Sentinel offers three retention tiers — choose the right one per data class. Pricing converted to INR at ₹98/USD; verify against the Azure India pricing page at quote time.
| Tier | Use for | Retention range | Approx INR per GB/month |
|---|---|---|---|
| Analytics | Hot, queryable logs — security events, detection content runs against these | Up to 2 years | ~₹220–280 / GB / mo ($2.30–2.85) |
| Auxiliary Logs (preview) | High-volume sources at lower compute (CDN logs, large telemetry) | 30 days hot + archive | ~₹30–60 / GB / mo ($0.30–0.60) |
| Archive | Long-tail retention for compliance — RBI multi-year, SEBI CSCRF | 2-7 years | ~₹2–5 / GB / mo ($0.02–0.05) |

Commitment tiers (100 GB/day, 200 GB/day, 500 GB/day, 1 TB/day) discount Analytics pricing by 15-65% depending on tier — significant for production workloads. See our Sentinel pricing post for the worked math.
Mapping CERT-In's 6-hour clock to Sentinel + managed SOC
T+0 — Event lands in Sentinel
Connector ingests from Defender XDR / Microsoft 365 / Entra ID / Azure Activity / custom app log.
T+5-15 min — Analytics rule fires
Microsoft-curated rule (or custom KQL detection) creates a Sentinel incident with severity + tactic mapping (MITRE ATT&CK).
T+15-30 min — Tier-1 triage
SOC analyst (Ogma's managed team or your in-house) opens the incident, runs initial KQL queries, classifies as TP / FP / suspicious.
T+30-60 min — Playbook containment
Automated Logic App playbook isolates the endpoint via Defender, disables the user in Entra ID, blocks the IOC. Manual approval gate for high-impact actions.
T+1-3 hr — Incident package + CERT-In format report
Forensic detail compiled from Sentinel timeline. CERT-In report drafted in the prescribed format with incident type, time of detection, IOCs, affected systems.
T+3-4 hr — Security lead approval + CERT-In submission
Customer's security lead reviews + signs off. Report submitted via the CERT-In channel. 2 hours of buffer remaining on the 6-hour clock.
Where Sentinel + Defender XDR delivers
▸ Identity threat detection
Entra ID Identity Protection + Defender for Identity feed Sentinel — credential stuffing, OAuth abuse, MFA fatigue, impossible-travel.
▸ Endpoint forensics
Defender for Endpoint Advanced Hunting telemetry available in Sentinel via the M365 Defender connector.
▸ Email security
Defender for Office 365 phishing + BEC signals correlate with identity + endpoint in Sentinel for unified incidents.
▸ Cloud workload
Defender for Cloud (formerly Azure Security Center) findings + Azure Activity logs ingested natively.
▸ SaaS visibility
Defender for Cloud Apps surface SaaS user behaviour — Shadow IT, OAuth grants, anomalous downloads.
▸ Threat intelligence
Microsoft Threat Intelligence + custom TI feeds enrich every incident with IOC reputation + actor attribution.
An anonymised India engagement
A real outcome — anonymised
Indian SaaS firm, 800 staff, RBI-regulated (PA-PG), prior in-house SIEM
The incumbent stack was an older on-prem SIEM with limited M365 visibility and no SOAR. Last RBI audit cycle flagged incomplete 24×7 monitoring evidence + missing Entra ID detection coverage. Sentinel migration completed over 12 weeks. Ogma's managed SOC took over Tier-1 monitoring.
Outcome: 41 detections in first 3 months (vs 8 in the prior 3 months on the legacy SIEM) — credential theft caught early, BEC attempt against finance team blocked at OAuth grant stage, three Defender for Cloud misconfigurations remediated. The next RBI audit cycle closed the 24×7 monitoring finding with a written-evidence report generated directly from the Sentinel workspace.
