What are the best ERP software systems and why? 

Has anyone drafted an SOW for a cloud-based SIEM with setup, migration, and maintenance? I’m working on a FedRAMP-authorized SIEM SOW, migrating from on-prem Splunk, covering data, searches, alerts, dashboards, and models.  Scope includes Environment Setup:  Cloud provisioning, configuration, testing. Connectors/Parsers: Custom data source integration. Content Development: Rules, use cases, threat feeds. Performance Tuning: Query/index optimization. Runbooks: Operational procedures. Also required: 24x7 support, maintenance, lifecycle and application management, role-based training, and documentation.  Must comply with NIST SP 800-53, CJIS, and FedRAMP Moderate+. Goal: Secure, scalable SIEM for rapid deployment. I may be missing elements, so suggestions are welcome. Please share redacted SOWs or tips if possible.
