  4. • This slidedeck is inspired from the great TechCommunity Post

    about how to become a Sentinel Ninja: https://techcommunity.microsoft.com/t5/azure- sentinel/become-an-azure-sentinel-ninja-the- complete-level-400-training/ba-p/1246310 • and was originally partly created by Ofer Shezaf, Principal Program Manager at Microsoft.
  5. Security Operations Challenges Expanding digital estate

  6. Too many disconnected products 76% report increasing security data* 3.5M

    unfilled security jobs in 2021 Lack of automation 44% of alerts are never investigated IT deployment & maintenance Sophistication of threats Security operations challenges
  7. A cloud native SIEM For the Cloud And for on

    premises security information event management security orchestration automated response
  8. Getting started with Sentinel2Go

  9. • Auto-scales • Easy collection from cloud sources • Avoid
