Because NetFlow relies on IP and Port, encryption does not stop NetFlow (unlike Deep Packet Inspection). However, the rise of ESNI (Encrypted Server Name Indication) and QUIC/HTTP3 makes it harder to identify the specific application. Port 443 could be web traffic, streaming, or hidden malware tunnels.
Standard NetFlow primarily provides Layer 4 data (IPs and ports). However, modern organizations are increasingly looking for . This "application-aware" flow data allows analysts to see not just that traffic is moving over port 443, but specifically which application (e.g., Salesforce, Zoom, or Facebook) is responsible for it. Conclusion netflow analytics
Supports all major flow exporters: Cisco, Juniper, Arista, Fortinet, and open-source tools like nProbe. Because NetFlow relies on IP and Port, encryption
Modern NetFlow analytics uses more than just the 5-tuple. Modern standards (like IPFIX) and advanced analyzers look at . Standard NetFlow primarily provides Layer 4 data (IPs
