SIGNL4

SIGNL4 is a mobile-first incident response platform designed to bridge the gap between your IT or OT systems and your on-call teams. You can connect your existing monitoring tools, IoT sensors, or manufacturing systems to ensure that critical alerts reach the right person at the right time through persistent mobile notifications.

You can manage on-call schedules with a simple drag-and-drop interface and track incident ownership in real-time.

Splunk On-Call

Splunk On-Call, formerly known as VictorOps, is a purpose-built incident management platform designed to make on-call rotations less painful for your engineering teams. You can automate the entire incident lifecycle by routing alerts from your monitoring tools directly to the right person at the right time. By centralizing your alert data, the platform ensures that your team has the full context needed to diagnose problems without switching between multiple tabs or tools during a crisis.

You can manage complex on-call schedules, set up automated escalation policies, and use native mobile apps to respond to incidents from anywhere. The software focuses on reducing your Mean Time to Resolution (MTTR) by providing a collaborative timeline where your team can chat, share snippets, and track remediation steps in real-time. It is particularly effective for DevOps and SRE teams in mid-market to enterprise organizations who need to maintain high service availability.
