Feature comparison: LogRythm vs Splunk

Below is a head-to-head comparison between LogRhythm and Splunk.

Deployment options

LogRythm users have flexible deployment options to match varying needs and goals. The deployment choices available to customers include self-hosting, infrastructure as a service (IaaS), or engagement with a managed security service provider. There is also a cloud deployment option with LogRhythm Cloud, which presents a software-as-a-service (SaaS) choice.

On the other hand, Splunk users can deploy the solution in a distributed search or single instance deployment. In addition, the software is also available as cloud, on-premise or multi-cloud.

Data analysis

When it comes to data analysis, LogRhythm’s Machine Data Intelligence (MDI) functionality helps users to make sense of their data. This functionality contextualizes and enriches data at the time of ingestion. It also helps to translate complex data into digestible chunks of information to enhance the accuracy of data analysis.

Splunk also has a data analytic engine designed to gather, index and manage large volumes of data, regardless of its format. Splunk’s data analytics can analyze data in real-time and dynamically generate schemas. This eliminates the need for users to have a deep understanding of the underlying data structure, as they can easily query and explore the data without any prior knowledge.

Customizable dashboard

LogRhythm allows users to customize their dashboards in ways that suit them. For instance, users can decide to customize the report template, create custom log detail reports, restore the default logo to a report, schedule and manage scheduled reports, rename a custom dashboard and decide which dashboard to make public or private.
