What is security monitoring software?

It is software that continuously collects and analyzes data from endpoints, networks, cloud services, and logs to flag suspicious activity, policy violations, and known threats in near real time.

How is security monitoring different from a SIEM?

SIEMs focus on aggregating and correlating log data for compliance and investigation, while security monitoring tools are broader, often including behavioral analytics, threat hunting, and active threat detection across more data sources.

Do small businesses need security monitoring?

Smaller organizations benefit from lightweight, cloud-delivered monitoring for endpoints, email, and identity rather than building a full SOC. Many MSPs offer managed monitoring as a lower-cost alternative.
