Network Security Monitoring Providers
123 providers
Network Security Monitoring (NSM) continuously watches network traffic for intrusions, lateral movement, data exfiltration, and other suspicious activity. Managed NSM deploys sensors at key network boundaries and internal segments, using signature-based detection, behavioral analytics, and flow analysis to catch threats that endpoint tools may miss.
Organizations with complex or distributed networks use NSM to spot traffic patterns they'd otherwise never see. MSSPs run this as a managed service because it needs specialized infrastructure, constant tuning to cut noise, and analysts who can tell real threats from normal traffic in high-volume environments.
How to Evaluate an MSSP for Network Security Monitoring
- Ask where the provider deploys network sensors and whether they cover both north-south (perimeter) and east-west (internal lateral) traffic.
- Understand the detection methods used: signature-based IDS, behavioral analytics, and flow analysis each catch different types of threats.
- Clarify the provider's approach to encrypted traffic monitoring, since increasing TLS adoption limits visibility unless SSL/TLS inspection is in place.
- Ask how the MSSP handles the high alert volume that network monitoring generates, and what their false positive reduction strategy looks like.
