Frequently asked questions
What is the difference between SIEM and SOAR?
SIEM (Security Information and Event Management) focuses on collecting, aggregating, and analyzing log data to detect potential threats and generate alerts. SOAR (Security Orchestration, Automation, and Response) takes the alerts from a SIEM and automates the response actions, such as blocking an IP address or quarantining a device, through predefined playbooks.
What is UEBA and why is it important in a modern SIEM?
UEBA stands for User and Entity Behavior Analytics. It uses machine learning to establish a baseline of normal behavior for users and devices on a network. It's critical for modern SIEMs because it can detect sophisticated threats like insider attacks or compromised accounts that don't trigger traditional rule-based alerts.
How should I choose between a cloud-native and an on-premises SIEM?
Choose a cloud-native SIEM if you prioritize scalability, reduced infrastructure management, and easy integration with other cloud services. Opt for an on-premises SIEM if you have strict data residency requirements, significant investments in on-prem infrastructure, or need complete control over your data and environment.
