Autonomous threat triage and fast MTTR without building an internal SOC

The real win with UnderDefense Agentic AI SOC is how it handles cross-domain threat correlation and autonomous triage. Instead of dumping raw alerts on our team, its AI agents run multi-step investigations across our cloud, identity, and SaaS apps in parallel. It automatically builds out the incident timeline, checks the evidence, and gives us a clear root-cause analysis before anyone has to look at raw logs.

Instant detection and response for suspicious API and cloud activity, backed by clear AI reasoning

UnderDefense Agentic AI SOC tells us early when one of our LLM API keys or cloud credentials is being used in a way that does not fit our projects. If a key is called from an unfamiliar location, or cloud usage climbs overnight, we get a single finding with the reasoning attached and rotate the key the same day. For a studio like ours that matters, because a leaked key means access to client work and a bill nobody approved. The analyst on our account knows how our projects are set up, so escalations stay short and our time goes into shipping product.

Background monitoring that investigates and contextualizes alerts before we even see them

Managing high-volume infrastructure meant our team was drowning in raw logs and false positives. UnderDefense took that off our plate by filtering out the background noise and isolating real risks. The platform connects the dots across systems and gives us clean context instead of raw alerts. It caught anomalies we would have spent hours hunting for manually, saving the team real time every week while keeping our monitoring solid.
