In an article on TMC Net, the value of network security is explored. As reported,Cisco's Netflow is the most popular mechanism for traffic-flow monitoring but an IETF standard is expected that will create a vendor-neutral format for traffic flow collection. Firewalls, anti-virus, IDS/IPS, access control and data loss prevention tools are important to ensure the network operates as expected and by using netflow, the information captured can provide visibility into true performance.

"Without netflow, network engineers only see traffic information for a fraction of the links in the network. As a result, they can only tell which end devices are exchanging traffic across the network, not how specific flows or all traffic in aggregate is traversing the network. When combined with real-time information about network-wide routing state, using netflow to capture information becomes very powerful."
