This document discusses on-premises vs cloud-based security information and event management (SIEM) solutions. On-premises SIEMs allow for data storage location customization and extended control, but have higher deployment and maintenance costs. Cloud-based SIEMs offer pay-as-you-go pricing and faster implementations, but come with increased security risks and limitations to accessing raw logs. The document also briefly introduces extended detection and response (XDR) solutions and notes they provide unified telemetry analysis and faster threat detection, response, and resolution.

3. How SIEMs
become trendy?
The idea of collecting data
from logs and using this data
for analyzing the behavior of
software applications,
endpoints and servers dates
back to the 80s.

4. Gartner Magic Quadrant related to SIEMs
Two Gartner experts coined the
term Security Information and
Event Management in 2005
when most SIEM solutions were
still operating on-premises.
