Fast autonomous threat containment that cut our investigation overhead across cloud and dev stacks

We eliminated alert fatigue and cut our incident investigation time down to seconds by replacing manual log triage with UnderDefense Agentic AI SOC. The AI agents connect directly into our cloud environments and dev pipelines, automatically running multi-step investigations across user access, repositories, and cloud workloads in parallel. They immediately contain potential threats, strip away ordinary background noise, and present complete root-cause summaries without slowing down our development speed.

Automated threat triage that keeps our infrastructure safe in the background

Keeping an eye on security around the clock usually means dealing with constant false alarms or digging through endless system logs. UnderDefense Agentic AI SOC connects right into our cloud setup and handles that initial layer of monitoring automatically. It filters out the background noise, analyzes suspicious activity on its own, and only alerts us when there's a real issue that needs our attention.

Hands-off threat monitoring that actually keeps false alarms away

It acts as a reliable filter for our cloud stack. Instead of flooding us with raw data or random pings every time a bot scans an endpoint, it processes everything silently in the background. It only escalates items that actually represent a valid threat vector, which keeps our team focused on shipping features instead of chasing ghosts.
