Network Security Monitoring

Splunk is a Big Data platform which has been widely used for Network Security Monitoring for LAN, WAN, DMZ, secure network, and internet.

There are more than 300 applications available on Splunk for security and compliance, thus it supports almost all major network security companies on market, such as : Cisco, Symantec, Trend Micro, Juniper, Check Point, Blue Coat, F5, Qualys, Citrix, RSA, and many more.  Splunk can grab security threats from dissimilar event sources like firewall, IPS/IDS, wireless network, computer endpoint,  and network appliance.

In general implementation best practices, Splunk runs in co-existence with existing network security solutions that a company already have.  Splunk helps to analyze security posture for multiple devices, visualize it into a business friendly dashboard, and provide audit friendly report for compliance and risk.
