Analytics at the source: A distributed approach to network security
Briefly

The centralized approach suffers from issues such as traffic duplication, high costs, and limited analysis accuracy due to reliance on extracted data like metadata or NetFlow.
As enterprises grow, the limitations of centralized network monitoring, including performance impacts and storage costs, become significantly more pronounced, urging a shift to distributed traffic analysis.
Centralized network security solutions may be cost-effective for small networks, but they struggle to scale effectively, rendering them inadequate for larger, complex infrastructures.
A better alternative lies in performing traffic analysis at the source in a distributed manner, which can alleviate the downsides of traditional centralized approaches, enhancing scalability and performance.
