What is SIGNL4?

SIGNL4 is a real-time mobile alerting solution that bridges the "last mile" between critical systems and the responsible staff, engineers, or IT admins. In the event of system failures or incidents, SIGNL4 reliably notifies personnel via push notifications, SMS, email, or voice calls. The platform features acknowledgement, tracking, and escalation management, along with integrated duty and shift scheduling to ensure the right people are alerted at the right time.
