Alerts worth acting on, nothing we have to sort through ourselves

Alerts come filtered and correlated, so what reaches us is for sure worth the attention, not something we have to sort through ourselves. That matters especially because our whole product is built around precision over noise, fewer signals worth acting on, not a flood of activity for its own sake, and it felt off to hold our own security tooling to a lower standard. Response has been fast whenever something genuinely needed a look.

Keeping client data under watch from the first export to the day it is deleted

UnderDefense Agentic AI SOC follows where our clients' customer and order data ends up during a migration. If an export file is copied somewhere unexpected, or a staging store holding real customer records is opened by someone who has no reason to be in it, we get a single finding with the reasoning attached and can act on it straight away. Migration projects leave copies of that data on laptops and test stores, and tracking every one of them by hand was a risk we kept pushing down the list. Now those copies stay watched until they are removed, including after a project has closed.

Spotting accounts that stop behaving like normal customers, with the reasoning attached

UnderDefense Agentic AI SOC keeps an eye on how our platform is being used, and what I value most is that it tells us when an account's behavior stops looking like a normal customer. Bulk exports, sign-ins that cluster in odd ways, usage that ramps faster than a real user would, all of that arrives as one explained finding we can act on the same day. Our product is a large database of creator data that customers can search and export, so that visibility protects the part of the business that matters most. The analyst on our account knows how our exports and limits work, which saves us a lot of back and forth.
