SIGNL4
Mobile-first alerting and response for IT, OT and security operations
SIGNL4 is a mobile-first alerting and response platform that connects critical systems with the people who need to act on them. It addresses the gap between problem detection and response by delivering alerts across push, SMS, voice and email, tracking delivery end-to-end, processing acknowledgements, and escalating automatically until a responder takes ownership.
Core capabilities include on-call duty scheduling, live call routing with voicemail, incident chat threads per alert, stakeholder communication, and alert grouping and filtering. AI features cover alert summaries, intelligent routing, duty scheduling, and pattern insights, with individual toggles for AI capabilities. Integrations are provided through email, webhooks, REST API, and two-way connectors, alongside an Edge Proxy for on-premises systems. The mobile app supports acknowledgement, escalation, on-call management, and incident context on iOS and Android.
SIGNL4 is aimed at IT and security operations, MSPs, industrial OT, IoT, SCADA, field service, and building automation environments. It is offered as a free 30-day trial, with pricing details available on the vendor's pricing page.
