SaaS (Software as a Service) delivers software applications over the internet but does not inherently include managed security log monitoring performed by the provider on the customer's behalf.

MaaS (Monitoring as a Service) is a managed cloud service where the provider takes responsibility for the ongoing collection, analysis, and review of security logs and events on behalf of the customer.

PaaS (Platform as a Service) provides a development and deployment environment for building applications but does not include outsourced security log monitoring and analysis.
