CST VerdictShort answer
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. Security teams building AWS infrastructure from scratch or remediating widespread misconfigurations will find AWS Security Architectures most valuable; it automates the tedious work of validating controls across accounts before they drift, which is where most teams actually fail. The free pricing and GitHub availability mean you can pilot it in a single account without procurement friction. Skip this if your team already has a mature CSPM with compliance reporting baked in; AWS Security Architectures prioritizes configuration validation and event monitoring over audit trails and evidence collection for certification audits.
