UnderDefense Agentic AI SOC Delivers Trusted 24/7 Coverage With Fast, Validated Alerts

Shipping software is what we do. Security operations is a full-time job for people who specialize in it. We delegated it entirely to UnderDefense Agentic AI SOC. Every alert across our infrastructure gets picked up within 2 minutes, investigated by AI agents that correlate events across our environments, and either closed or escalated with full reasoning attached. By the time anything reaches us, the investigation is done. We went from no visibility outside business hours to continuous 24/7 coverage. The findings that reach us are validated. The team stays on the product.

The system connects directly into our existing infrastructure and translates raw log telemetry into clear operational context. It gives us round-the-clock threat visibility that easily satisfies the strict security requirements our enterprise partners demand. The pricing is market-based, and we’re always comfortable with the price control. There are no unexpected changes or misunderstandings. Overall, everything is well-controlled and transparent.
