Multiply Suricata IDS
by a factor 4

For Intrusion Detection implementations, missing any significant fraction of network traffic is unacceptable, as even a single packet not inspected by the Intrusion Detection System (IDS) represents a blind spot for the security team. Suricata IDS detects known threats, policy violations and malicious behavior. However, as capable as Suricata is in reactively protecting a network, it will only be as effective as its implementation.

Find out how hardware acceleration can multiply Suricata performance by a factor 4, while ensuring that not a single packet goes unnoticed.

Analytics in full flow
Flow records for advanced flow analytics

For efficiency, a lot of monitoring and analysis tools focus on flow records to detect anomalies in the network - and only dive to the underlying packet level if needed.

In this blog, Chief Product Architect Alex Agerholm discusses typical use cases, looks at NetFlow/IPFIX acceleration and speculates on the imminent future of flow processing.
