Seamless 24/7 threat response with full-stack Agentic AI automation

Partnering with UnderDefense Agentic AI SOC completely changed how we handle platform security. Their autonomous agents take full ownership of our event monitoring, instantly sifting through raw cloud signals to detect suspicious patterns. Instead of sending endless alerts, the system automatically investigates the root cause, verifies it against our access policies, and delivers a concise summary only when genuine action is needed.

Streamlined security operations that protect our domain reputation

UnderDefense Agentic AI SOC completely took the daily grind out of our incident monitoring. Running a link management and QR infrastructure means we're a constant target for automated bot sweeps, link abuse, and random API traffic spikes. Their AI agents run quietly across our stack, parse through incoming log noise, and handle triage on their own. Instead of dumping raw alerts on our lap, the system runs multi-step checks against our security policies and only drops a message in our Slack channel when an issue actually needs a decision from our team.
