It's 2 AM. An alert fires. Possible data exfiltration. Your on-call analyst is three time zones away, half-asleep, context-switching between tools.

By the time they piece together the evidence, forty-five minutes have passed. Was it a real threat or another false positive? The clock is ticking.

Tomorrow, I'll tell you how 300 enterprises solved this exact problem. But if you can't wait, head over to dropzone.ai to learn more.

Here's a security tip most vendors won't tell you. Your SOC analysts aren't slow. They're drowning. The average enterprise faces tens of thousands of alerts daily, and even your best analysts can only investigate so many before burnout wins.

Dropzone AI changes that math. Their AI SOC agents autonomously investigate every alert, no playbooks or code required, in three to ten minutes flat.

Stop triaging. Start defending. Book a demo at dropzone.ai.
