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.
AWS teams with drift-heavy environments should start here; AWS Config catches resource configuration changes in real time at zero marginal cost, making it the fastest way to enforce consistency across accounts. It's native to AWS, deploys in minutes, and feeds directly into compliance frameworks like CIS Benchmarks and PCI DSS without additional licensing. Skip this if you need cross-cloud CSPM or deep remediation automation; Config excels at visibility and audit trails for AWS-only shops, not orchestration across Azure or GCP.
