24/7 Infrastructure Protection While Our Team Stays Focused on the Roadmap

Our core team's focus has always been building features and maintaining our SDKs, which left us with no capacity for around-the-clock monitoring. Bringing in UnderDefense filled that operational gap so our devs and DevOps engineers don't have to play security analyst on the side. The system filters out the noise, escalates only what matters, and automatically factors in our environment so we're not stuck manually investigating every blip.

Reliable coverage for an agency that handles dozens of client environments

We run campaigns, manage ad accounts, and maintain website infrastructure for clients across multiple industries. Security incidents in any of those environments create client escalations, not just technical problems. We needed coverage that matched that exposure, without building an internal security function. The UnderDefense analyst assigned to our account knows our environments and reaches out when something actually requires our attention. Our people stay focused on client work, and when a security issue comes up, we're getting a clear picture of what happened rather than trying to figure it out ourselves.

Took the investigative load off without taking control away

Our engineers are in databases all day: migrations, bulk scripts, direct production access across multiple environments. Any security tool treats that as constant noise, and maintaining exclusion rules that broke with every infrastructure change was eating time we didn't have. What shifted things is that the AI learns operational context instead of matching patterns. A developer running a heavy script during a documented change window gets handled automatically. Analysts only see what actually needs a decision. It connected into our existing SIEM and identity provider without rebuilding anything, and starting in advisory mode before gradually extending autonomy made internal sign-off straightforward.
