Automated security monitoring that investigates complex operational signals before escalating

Authentication patterns across hundreds of API integrations are monitored continuously. When something deviates, it gets investigated automatically and reaches us with the work already done. We review a finding with context, not a raw log with no one to trace it. We manage access to client advertising accounts across multiple platforms at significant volume. One compromised token can cause real damage within hours. Monitoring that manually across a distributed team wasn't viable. UnderDefense Agentic AI SOC covers that layer continuously. By the time something escalates to us, less than 2 minutes have passed since the signal.

Scaling 24/7 security across multi-timezone projects.

Our internal IT and ops teams managed day-to-day operations, but maintaining 24/7 monitoring across our active infrastructure and 100+ ongoing projects was impossible. UnderDefense closed those after-hours gaps completely. The biggest win is automated noise reduction: false positives are cut by roughly 80–90% before hitting our queue, so our team only handles high-priority alerts that actually require action. Plus, having full environmental context on every incident saves us hours of manual investigation.

Autonomous monitoring that actually understands dev workflows and cuts out noise

The main win for us is how it handles monitoring across a large infrastructure without getting in the way of our daily engineering. It connects right into our cloud setup, code repos, and identity providers, filtering out all the background noise from routine deployments and temp credentials. Instead of blowing up our Slack with false alarms, it quietly triages everything and only pings us when something actually needs a human look. When it does, we get a clear picture of what happened instead of having to dig through raw logs. It took a ton of pressure off our team and gave us solid 24/7 coverage without needing to hire a separate SecOps team.
