- 31. 31 Replacing a SIEM @ Cisco 31 We moved to Splunk from traditional SIEM as Splunk is designed and engineered for “big data” use cases. Our previous SIEM was not and simply could not scale to the data volumes we have. ““ Gavin Reid, Leader, Cisco Computer Security Incident Response Team Challenges: SIEM could not meet security needs – Very difficult to index non-security or custom app log data – Serious scale and speed issues. 10GB/day and searches took > 6 minutes – Difficult to customize with reliance on pre-built rules which generated false positives Enter Splunk: Flexible SIEM and empowered team – Easy to index any type of machine data from any source – Over 60 users doing investigations, RT correlations, reporting, advanced threat detection – All the data + flexible searches and reporting = empowered team – 900 GB/day and searches take < minute. 7 global data centers with 350TB stored data – Estimate Splunk is 25% the cost of a traditional SIEM
