One limitation of SIGNL4 is its purely cloud-based availability. Since the platform depends on an active internet connection, configuration and alert handling can be impacted in environments with unstable connectivity or strict offline requirements. For organizations with strong on-premises, compliance, or disaster-resilience demands, this can be a drawback. Providing enhanced offline capabilities or an optional local component could further broaden SIGNL4’s applicability in highly critical or regulated environments.
