Fast, Actionable Alerts That Keep Our Payment IntegMonitoring for online stores hosted in different

Alerts come filtered and correlated, so what reaches us is worth acting on, and whoever's on our account already knows how our projects are structured. Response has been fast whenever something actually needed a look. That matters specifically because the stores we build handle live payments for our clients, so anything odd around checkout or payment integrations isn't something we can afford to notice a week later.

UnderDefense routes fully triaged SOC alerts into Slack so our team only acts on real threats

Maintaining threat visibility across our internal tools and staging setups usually means dealing with severe alert fatigue from background API syncs and build jobs. UnderDefense Agentic AI SOC completely fixes this by native integration into our Cloudflare, cloud instances, and IAM stack. Instead of forcing us to monitor a noisy dashboard, it contextually enriches telemetry at the AI layer and routes fully triaged incidents directly into our Slack channels. Receiving the root cause, blast radius, and correlated logs attached directly to the alert means our team only steps in when a genuine anomaly demands immediate action.

Autonomous AI SOC that effectively filters out noise in high-volume telecom traffic

UnderDefense handles our high-volume telecom traffic exceptionally well. Operating a cloud telephony and virtual number platform means processing thousands of real-time SIP sessions and API calls every second, which caused traditional tools to flood us with false alarms during normal traffic spikes. UnderDefense’s AI actually understands telephony context—it instantly filters out background noise and flags only legitimate security risks, like SIP credential abuse or suspicious webhook changes.
