Product
Microsoft Sentinel — cloud-native SIEM and SOAR running on Azure. Per-GB-ingest commitment-tier pricing with built-in UEBA, Logic Apps automation, Workbooks, Hunting, and Threat Intelligence integration.
Where it lives
Azure Log Analytics workspace. Indian-region deployment in Azure Central India (Pune) or South India (Chennai). Data residency for the Sentinel workspace stays in the selected region.
Connectors out of the box
Microsoft 365 / Entra ID / Defender XDR / Defender for Cloud / Office 365 audit, AWS CloudTrail, GCP audit logs, FortiGate / Cisco / Palo Alto / Check Point syslog, Linux / Windows event forwarder, custom Logstash / Syslog.
Licensing
Pay-as-you-go per GB or Commitment Tiers (100 / 200 / 300 / 400 / 500 GB/day) — the higher the commitment, the lower the per-GB rate. Microsoft 365 E5 customers get included Sentinel data benefit.
SOAR / automation
Native Logic Apps integration for playbook authoring. Ogma builds custom playbooks (enrichment, mailbox sweep, AD password reset, FortiGate firewall block) and connects them to incident triggers.
Indian compliance fit
RBI Cyber Security Framework, SEBI CSCRF (2026), DPDPA 2023, CERT-In 180-day log-retention (Sentinel default retention is 30–90 days; long-term archive routes to Log Analytics archive or Blob storage).
Managed-SOC option
Ogma operates Sentinel as a managed-SOC service — 24×7 monitoring, rule tuning, threat hunting, audit-evidence packaging. Per-EPS or per-GB pricing models available.
Commercial via Ogma
Sentinel consumption billed under Ogma's CSP — INR invoicing, Indian-entity contracting, GSTIN, monthly billing, no FX exposure.

Microsoft Sentinel — Deployment & Managed SOC Capabilities

End-to-end Sentinel services — from workspace setup to 24x7 SOC operations.

Microsoft Sentinel Deployment

Sentinel workspace setup on Azure, data retention configuration, cost management (commitment tiers), and initial connector deployment for Microsoft 365 (via Defender XDR), Azure Activity, and Windows Security Events.

Data Connector Setup

Sentinel has 200+ native connectors: Microsoft 365 Defender, Azure AD, Azure Activity, Fortinet FortiGate (syslog/CEF), Cisco ASA, CrowdStrike Falcon, Palo Alto, AWS CloudTrail, and custom CEF/syslog for any device with RFC 5424 syslog output.

KQL Analytics Rules

Ogma's security analysts write KQL (Kusto Query Language) analytics rules to detect specific attack patterns — credential spray, lateral movement, ransomware pre-cursor activity, and insider threat indicators — tuned for your environment to reduce false positive fatigue.

SOAR Automation (Playbooks)

Microsoft Sentinel Playbooks (Logic Apps) automate response actions: isolate a compromised device in MDE, block an IP in FortiGate, disable an AD account, or notify the SOC via Teams/email — triggered automatically when high-confidence alerts fire.

UEBA & Anomaly Detection

Sentinel's User and Entity Behavior Analytics (UEBA) builds behavior baselines for users and devices — detecting anomalous logins, impossible travel, excessive data access, and admin activity deviations without requiring signature rules.

Compliance & Reporting

Sentinel's workbooks provide built-in compliance dashboards (NIST 800-53, ISO 27001, CIS Controls, DPDPA 2023). Ogma builds custom executive dashboards and incident trend reports for monthly security reviews.

Why Choose Ogma for Microsoft Sentinel?

Sentinel-Certified Architects

Ogma's security architects are certified in Microsoft Sentinel deployment — workspace sizing, connector roadmaps, and retention cost optimization based on real-world Sentinel deployments in India.

KQL Expertise

Ogma's analysts maintain a library of tuned KQL detection rules for common attack patterns in Indian enterprise environments — adapted from real threat intelligence and red team findings.

24x7 Managed SOC

Ogma's managed Sentinel SOC provides round-the-clock incident monitoring, weekly threat hunting, analytics rule tuning, and monthly security posture reporting — with defined SLAs for alert response and escalation.

How Ogma Deploys & Manages Microsoft Sentinel

1
Workspace Setup

Ogma creates the Sentinel workspace on Azure, configures data retention tiers, selects commitment vs PAYG pricing, and deploys initial Microsoft connectors (M365 Defender, Azure AD, Azure Activity).

2
Connector Deployment

Ogma deploys data connectors in priority order based on your risk profile — Microsoft stack first (free), then firewall syslog/CEF via DCR agents, then third-party security tools via API connectors.

3
Rule Development

Ogma's analysts develop and tune KQL analytics rules for your environment — starting from the Microsoft security template library and extending with custom rules for your specific technology stack and threat model.

4
SOC Onboarding & Managed Operations

Ogma onboards your Sentinel instance to the managed SOC: integrates with ticketing, defines escalation paths, deploys initial Playbooks, and begins 24x7 monitoring with monthly security reports.

Frequently Asked Questions — Microsoft Sentinel India

Sentinel is priced on data ingestion volume (GB/day) with two models: Pay-As-You-Go (per GB ingested) and Commitment Tiers (pre-commit 100-5000+ GB/day for up to 65% discount). M365 E5 customers get 50MB/user/day of Sentinel ingestion free for M365 data. Ogma optimizes connector selection and data filtering to minimize ingestion costs.

Priority order for most Indian enterprises: (1) Microsoft 365 / Defender XDR (free for E5); (2) Azure Activity and Azure AD Sign-In logs; (3) Windows Security Events from servers; (4) Firewall logs (FortiGate/Cisco); (5) Endpoint events (MDE). Ogma defines the connector roadmap based on your risk priorities.

KQL (Kusto Query Language) is the query language used in Microsoft Sentinel for analytics rules, hunting queries, and workbooks. High-quality KQL analytics rules are what separate a Sentinel deployment that actually detects threats from one that generates noise. Ogma's analysts bring a library of tuned KQL rules for common attack patterns in Indian enterprise environments.

Sentinel Playbooks are Azure Logic Apps triggered by analytics rule alerts. Example: A credential spray alert triggers a Playbook that checks if the targeted account is a privileged account — if yes, it disables the account in Entra ID and sends a Teams notification to the SOC. Zero human action required for tier-1 response. Ogma designs and deploys Playbooks for your most common alert types.

Yes — Sentinel ingests CEF (Common Event Format) and syslog from any on-premises device. Ogma deploys a Log Analytics Gateway (or Azure Monitor Agent on a Linux VM) in your data centre to collect FortiGate, Cisco ASA, Aruba, or Palo Alto syslog and forward it to Sentinel in Azure. No public internet exposure required if you use ExpressRoute or VPN.

UEBA builds statistical baselines of normal behavior for each user and entity (device, IP). It then scores deviations from baseline — a user logging in at 3am from an unusual country, or an account suddenly downloading 10GB of data. UEBA catches novel attacks that don't match known signatures. It works alongside KQL analytics rules — both are needed for comprehensive detection.

Ogma's analysts monitor Sentinel 24x7 — triaging incidents, correlating alerts across connectors, performing threat hunting (weekly), managing analytics rule tuning, and providing monthly security reports. Confirmed threats trigger Ogma's incident response process: containment, investigation, remediation, and root cause documentation.
