Scaling security alert automation with agents and ChatOps
Description
This content describes a technical walkthrough and approach to scaling security alert automation using agents and ChatOps, specifically integrating AWS GuardDuty findings with Slack for distributed alert triage. It addresses challenges in mapping alerts to human owners, especially for host and infrastructure events lacking direct user identity in the alert payload. The approach uses an AI agent to automate investigation steps, owner identification, and alert response workflows, reducing manual effort and improving scalability. This is a security automation methodology rather than a vulnerability or exploit.
Reddit Discussion
My team wrote a technical walkthrough of the distributed alerting workflow we use internally. It uses an agent to investigate GuardDuty findings, identify owners, and handle responses in Slack.
Slack helped popularize distributed alerting by sending alerts directly to the people involved and asking whether they recognized the activity. Dropbox and Brex described similar approaches, but most teams we’ve spoken with struggled to scale beyond user-centric alerts where someone’s identity was already in the payload.
Our security engineer ran into this at his previous company. A suspicious login was straightforward to route, but an alert about a host or infrastructure change could take hours or days of work with detection engineers before they could reliably identify someone to ask.
We walk through a concrete Kubernetes example where the alert only names a service account. Finding a person means following the evidence through workload metadata, code ownership, deployment history, and identity logs. The tutorial shows how we turn that investigation method into reusable skills so an agent can work through those steps for each finding.
We cover:
- The history of distributed alerting and why deterministic workflows struggle to scale
- The estimated effort of building owner lookups across GuardDuty finding types
- How the agent uses skills, drilldown queries, and context from inventory, code, tickets, and logs
- The full flow from investigation to a Slack conversation and the owner’s confirmation
- Permissions, tool restrictions, observability, and keeping context current
What interested us most was extending this to host and infrastructure alerts that had been impractical to automate with individual lookup rules. The walkthrough includes the setup and examples so you can see how it works.
We know many folks were are divided by the use of agents in security automation. Hopefully this article on distributed alerting presents an example of something that wasn't possible / too time consuming to work before agents + context / skills driven automation vs fully determined paths.

Technical Analysis
The article details how Tracecat employs an AI-driven agentic system to automate the triage of security alerts from AWS GuardDuty by converting detection events into Slack notifications, identifying the responsible owner through metadata and logs, and facilitating owner confirmation or escalation. It highlights the difficulty in scaling distributed alerting beyond user-centric alerts due to the absence of direct human identifiers in many host and infrastructure alerts. The system uses skills and drilldown queries to map these alerts to owners by correlating workload metadata, deployment history, and identity logs. This automation reduces the manual engineering effort required to build deterministic SOAR workflows for each alert type, which can otherwise take hundreds of engineer-hours. The content is a detailed technical explanation and tutorial rather than a report of a security vulnerability or active threat.
Potential Impact
There is no direct security impact or vulnerability described. The content focuses on improving the efficiency and scalability of security alert triage and response workflows. By automating owner identification and alert handling, organizations can reduce the time and effort required to respond to security findings, potentially improving incident response times and reducing alert fatigue. No exploitation or compromise scenarios are described.
Defensive Guidance
No mitigation is required as this is not a vulnerability or active threat. The content provides a methodology and open-source tools for security teams to implement automated alert triage and response. Organizations interested in adopting this approach should follow the deployment instructions and prerequisites described in the article, including setting up Tracecat, GuardDuty, Slack integration, and optionally SIEM and business context data.
