CST VerdictBased on our analysis of available product data, here is our conclusion:
Smaller security teams without budget for point tools will find AlienVault OSSIM's all-in-one approach valuable; the free pricing model lets you run asset discovery, vulnerability scanning, and SIEM collection on a single appliance without licensing friction. The platform handles event correlation across network, vulnerability, and asset data on the same box, which cuts operational overhead compared to stitching three separate tools together. Skip this if you're running high-volume environments (10,000+ events per second) or need deep customization in any single function; OSSIM trades depth for breadth.
Teams operating AWS environments who need fast audit trails of who changed what in their infrastructure will find AWS Log valuable; it's free, lightweight, and pulls directly from AWS Config without additional agents. The tool excels at the Govern function of NIST CSF 2.0, giving you configuration history that makes compliance documentation and change tracking straightforward. Skip this if you need real-time alerting on misconfigurations or cross-cloud visibility; AWS Log is a historical audit tool, not a live posture scanner.
