We implemented ELK (Elasticsearch, Logstash, Kibana) to analyze logs from Cisco and Huawei firewalls. We consumed the logs in real time using Logstash and after some processing and normalization we stored it in Elasticsearch for analysis. Also implemented an Kibana dashboard to visualize the data for different events and other details. It helped our client to have better visibility in their network for events, incidents and improve security based on information they get from this dashboard.
We are experienced in implementing Kiaban custom dashboard for visualization and analysis of data. I you have similar needs you can contact us to implement and optimize ELK stack.
