Watching the order data that flows through our sync, with clear finding when something is off

UnderDefense gives us complete control over the customer and shipping data passing through our system. It flags abnormal activity right away. A few examples: an unauthorized person accessing orders or someone making a massive data export. Instead of noisy alerts, we get a single, clear breakdown specifying the affected merchant account, allowing us to reach out same-day with precise details. Most of the time it's quiet, which gives us total confidence that our data pipeline is secure.

Complete visibility into the actual decision steps behind every security alert

Most SOC solutions send a brief summary and leave you to do the actual digging. UnderDefense Agentic AI SOC completely flipped that model by giving us the exact sequence of reasoning behind every alert. We can see which log sources were queried, what evidence was gathered, and how the conclusion was tested against our baseline before any escalation hits our desk. Having that transparent investigation trace—backed by a second automated check to prevent false assumptions—gives us total confidence in the results without LLM hallucinations or guesswork.

Keeping data endpoints open to customers because someone is watching how they are used

UnderDefense Agentic AI SOC tells us when the use of a published data endpoint stops looking like normal use. With our customers connecting via OData, ODBC, and MCP for AI agents, we constantly need to tell normal team work apart from scraping or oversharing AI agents. UnderDefense flags the exact user, endpoint, and suspicious queries alongside clear reasoning. Because our normal traffic is so high, this intelligent filtering is what allows us to confidently provide these endpoints in the first place.
