CloudTrail for AI Agents: Why Pre-Aggregation Matters
Security teams want answers like “What did Alex do yesterday?” but CloudTrail returns thousands of raw events. With SIEMs or CloudTrail Lake, you have to write complex queries, and they often overwhelm AI agents with raw, unfiltered data. This wastes tokens and leads to vague, unhelpful answers. TrailTool solves this by pre-aggregating CloudTrail events into entities: People, Sessions, Roles, Services, Resources. AI queries get concise, actionable answers without the noise.
Why Pre-Aggregation Matters
With raw CloudTrail, answering questions like “Did contractor@company.com use S3 in the last 30 days?” means sifting through thousands of events, writing custom queries, and correlating sessions by hand. TrailTool pre-aggregates these events into sessions and entities, so your AI assistant can instantly answer with clear, contextual summaries. No manual parsing or SQL required.
How It Works
TrailTool groups CloudTrail events into sessions, builds an entity graph (People to Sessions to Roles to Services to Resources), and generates AI-ready summaries as data arrives. Your AI assistant gets only the relevant, contextual data it needs, making queries fast, affordable, and useful.
Examples
alex@company.com (2:15pm - 2:58pm):
Incident Investigation: “What did admins do before the outage?” TrailTool: “Found 2 admin sessions. alex@company.com deployed CloudFormation stacks and updated API Gateway. admin@company.com modified a security group and restarted an EC2 instance. Likely culprit: security group change.”
Access Pattern Analysis: “Show me console activity in the last week.” TrailTool: “47 console sessions found. Top users: intern@company.com (23), contractor@company.com (12), alex@company.com (6). 843 CLI/SDK sessions were automated.”
Compliance Validation: “Did anyone outside engineering access the customer database last month?” TrailTool: “2 role assumptions outside engineering: finance@company.com (read-only Athena query), product@company.com (3 sessions, approved project). Both are documented exceptions.”
How TrailTool Fits In
TrailTool works alongside CloudTrail Lake and your SIEM. Use CloudTrail Lake for deep analysis and legal holds, SIEMs for alerting and dashboards, and TrailTool for fast, ad-hoc AI queries. TrailTool sends structured entity summaries instead of raw events.
