Introduction

Previously, we discussed how SIEM tools help security analysts monitor systems and detect security threats. In this reading, we will cover some industry-leading SIEM tools that you'll likely encounter as a security analyst.

Types of SIEM Tools

Organizations can choose from different types of SIEM tools based on their unique security needs:

Cloud-hosted SIEM Tools

  • Description: Maintained and managed by the SIEM providers, making them accessible through the internet.
  • Ideal for: Organizations that don't want to invest in creating and maintaining their own infrastructure.

Hybrid SIEM Solutions

  • Description: A combination of both self-hosted and cloud-hosted SIEM tools.
