Nowadays, IT organizations generate colossal amounts of data. Handling these chunks of data itself is critical in the IT world. Hence centralizing the log management system improves security thereby enhances data protection in an organization. Such enterprises require a high profiling tool that helps in managing the information and events data to improve the level of security.
