Key Use Cases Troubleshooting Performance Issues: Identifying that a 100% WAN link utilization is caused by unexpected Microsoft 365 traffic or a rogue backup job. Capacity Planning: Using historical traffic data to forecast when network links need upgrades. Security Threat Hunting: Detecting internal devices communicating with known malicious external IP addresses (command-and-control communication). SaaS Monitoring: Using path analysis to determine if slow SaaS performance is due to the user's ISP, the Internet, or the SaaS provider. Kentik +2 5. Future Trends: 2026 and Beyond AI-Driven Investigation: Moving from generating alerts to actionable insights, where AI tools (e.g., Kentik AI Advisor) can answer natural language questions like "Why is the WAN link slow?". Encrypted Traffic Analysis: Analyzing metadata from encrypted streams to detect threats without decrypting the traffic. Unified Observability: Network flow data is becoming integrated into broader observability platforms (logs, metrics, traces) to correlate network issues directly with application failures. Kentik +1 Summary Network flow analysis software is indispensable for ensuring network performance and security in 2026. While traditional enterprise tools like SolarWinds remain strong, SaaS-first, cloud-native platforms like Kentik and For companies heavily invested in hybrid cloud environments,
