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 that need immutable audit logs for compliance and incident response should start with CloudTrail; it's free, ships with AWS, and captures every API call across your account, making it the baseline that most security programs build on. The service is SOC 2 Type II certified and satisfies most regulatory audit requirements without additional tooling. Skip CloudTrail if you're looking for behavioral threat detection or real-time alerting on suspicious activity; it's a log collection engine, not an analytics platform, so you'll need a SIEM or security data lake downstream to actually find the signal in the noise.
