About SIGNL4

When an IT system, machine or sensor raises a critical event, the hard part is reaching the right engineer fast. SIGNL4, a mobile alerting and service dispatch product from Derdack, is built to close that last gap between monitoring systems and the engineers, IT staff or field workers who must act.

Persistent alerts with acknowledgement

Team members are notified through push messages, text and voice calls. Whoever sends an alert can see who has received it and who has accepted it, and unanswered alerts are passed along to other people. Duty scheduling and reporting are part of the same service. Derdack says the approach gives up to ten times faster responses to critical alerts, major incidents and urgent service requests.

Use cases by sector

The company lists mobile alerting in manufacturing, critical operations alerting in banking and financial services, and field service dispatching in energy and utilities, among other industries. It also points to use in managed IT services and enterprise IT alerting.

The larger Enterprise Alert product

SIGNL4 is the software-as-a-service route to alerting. Derdack's Enterprise Alert software serves on-premises and hybrid cloud deployments, with mobile alerts, drag and drop on-call and shift scheduling, chat-based collaboration with conference bridging, and a mobile app for remediating incidents from anywhere. A recent release added remote actions for hybrid scenarios and proxy support for Microsoft Teams. Derdack says it complements existing infrastructure and that global enterprises, including a Canadian railway, use its products, with technical support, an online knowledge base and local partners available to buyers. Its site describes reliability, integrations and security as part of the design.

Partners and the Azure Marketplace

Buyers can reach Derdack by region, and the company points to partners, a pricing and quotes page and an Azure Marketplace route for purchase.
