How we engage as your Microsoft Security partner
- Licence optimisation review: If you have Microsoft 365 E5, Azure landing zones or EA agreements, we map what is already paid for vs what you are using — typically uncovers significant unused capability.
- Sentinel architecture: India-region deployment, log-source prioritisation, cost-optimised retention tiers, integration with non-Microsoft sources (firewalls, EDR, identity systems).
- Defender XDR enablement: Endpoint onboarding, attack-surface reduction rules, automated investigation tuning, integration with Sentinel for unified SecOps.
- Entra / identity hardening: Conditional access design, MFA migration to phishing-resistant methods, PIM rollout, legacy authentication elimination.

Frequently Asked Questions
Are you a Microsoft Solutions Partner?
Yes — NexaSource is a Microsoft Solutions Partner aligned to the Security workload, with certified engineers and India-based managed services.
Which Microsoft certifications do your engineers hold?
SC-100 (Cybersecurity Architect), SC-200 (Security Operations Analyst), SC-300 (Identity), AZ-500 (Azure Security), and MS-500 / MS-101 across our team.
Can you keep Sentinel data in India?
Yes. We deploy Sentinel in Microsoft India regions (Central India / South India) by default for Indian customers requiring data residency.
Do we need full E5 to use Sentinel?
No. Sentinel is consumption-priced and works alongside any Microsoft licence level. However, E5 unlocks the broader Defender XDR experience, which significantly enhances Sentinel value.
Can you operate Sentinel and Defender for us 24×7?
Yes — our managed XDR (MXDR) service runs Sentinel and Defender XDR 24×7 from our Noida SOC with India-resident telemetry.
Can you migrate us from Splunk, QRadar or LogRhythm to Sentinel?
Yes. We have run multiple SIEM migrations to Sentinel — including parallel-run periods, content migration (rules, dashboards, playbooks) and cost-modelling exercises.
