/blog/splunk-vs-sumologic-vs-elk/

Businesses, particularly large enterprises, face the challenge of effectively analyzing and securing massive amounts of log data, with Splunk, Sumo Logic, and ELK being prominent solutions for log analysis and security information and event management (SIEM). Splunk offers robust data aggregation and analysis capabilities, but its setup complexity and high pricing can be drawbacks. Sumo Logic, on the other hand, offers a cloud-native, easy-to-use platform with scalability advantages, though it lacks some advanced features found in Splunk and can also be expensive. ELK, comprising Elasticsearch, Logstash, and Kibana, stands out due to its open-source nature, lower costs, and strong community support, though it may present setup challenges for inexperienced users. Ultimately, ELK is preferred for its cost-effectiveness and vibrant community, despite missing some features like alerting and anomaly detection present in other platforms.
