We built an agentic security investigation service to help us research alerts as part of our mission to keep Slack secure and protect our customers. Our service deploys teams of AI agents that collaboratively perform security investigations. AI agents free human analysts from tedious data gathering tasks. Over just the first quarter of their deployment, our agents have performed over 7,500 investigations, issuing over 500,000 tool calls. Our agents are enabling us to gain unprecedented real-time insight into Slack’s infrastructure in a way we could never do with human labor alone.
