CST VerdictShort answer
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. Security teams already running Zeek for network telemetry and Elasticsearch for log aggregation should use zeek2es.py to close the integration gap without custom Python work. The tool handles Zeek's native JSON output directly into Elasticsearch bulk format, cutting weeks off a DIY pipeline and eliminating parsing errors that leak events. Skip this if your team lacks Elasticsearch infrastructure or hasn't yet committed to Zeek; the narrow integration scope means it solves one problem exceptionally well and nothing else.
