Microsoft Sentinel SIEM

Microsoft Sentinel

Optimize security operations with cloud-native SIEM powered by AI and automation

Today, organizations are faced with the incredibly difficult task of trying to protect their expanded digital estate from increasing cyber threats. The move to the cloud, combined with an increasing mobile workforce, has pushed the border of an organization’s estate beyond the boundary of their physical network. Both their data and its users and systems are everywhere. Meanwhile the frequency and sophistication of attacks are consistently growing. Regardless of the size of the organization or the industry, everyone is a target.​

IT security is a challenge that most businesses struggle with. We believe that Microsoft Sentinel can be the answer.

Security Data Explosion

Regardless of the size of your organization or the industry, you are a target. As your digital estate grows, so does the volume of security data. In fact 76% of organizations report an increase and much of it is coming from in the cloud. So pumping it into legacy, on-premises systems (with all the deployment and maintenance overhead that comes with that) just doesn’t make a ton of sense. And that volume is just going to keep growing. Data is the fuel for ML models that have become so critical to threat detection. The models need both more signals and more diverse signals.

To shore up their defenses, enterprises have deployed dozens of security products, each producing a large volume of alerts. In isolation, these products may have high false positive rates and poor response prioritization, resulting in deafening alert noise. As a result, organizations report that nearly half of alerts (44%) are never investigated.
Part of the reason these alerts fall through the cracks is a massive shortage in security professionals.

  • 3.5M unfilled security positions in 2021
  • Too many disconnected products
  • 76% report increasing security data
  • Sophistication of threats
  • IT deployment and maintenance
  • 44% of alerts are never investigated
  • Lack of automation

Thankfully, the cloud can help manage the complexity of the expanding digital estate. It simplifies and makes security easy to manage. Harnessing the power of cloud will set your SecOps teams free of IT work and help them focus on security work with no limits.

Microsoft Sentinel offers a new, modern approach to Security Incident and Event Management (SIEM). Sentinel is entirely cloud-native and powered by AI and automation to help optimize security operations. Microsoft Sentinel’s cloud-native nature empowers users with the scale, flexibility, and speed of the cloud, while eliminating the time and money spent on managing complex infrastructure.

Microsoft Sentinel detects complex, evolving threats across massive volumes of low-fidelity signals using built-in machine learning developed by Microsoft security experts. It gives you everything you need to expedite incident response, streamlining investigations with robust incidents and equipping you with built-in automation. With these efficiency gains, Microsoft Sentinel gives you the ability to finally be proactive about finding and stopping threats with robust threat hunting tools to help security teams get, and stay, ahead of attackers.

Empowered SecOps Teams

Below are just a handful of examples of the efficiency gains Microsoft Sentinel brings to security operations


Sentinel is more cost effective, shown to be 48% less expensive than traditional SIEMs.


Sentinel is 67% quicker to deploy than legacy SIEMs, helped by its extensive pre-built content and out-of-the-box functionality.


Sentinel implementation results in a 79% decrease in false positives over three years.


Sentinel results in a 56% reduction in management effort by eliminating infrastructure management.
