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.

Splunk also offers a highly customizable dashboard. Users can choose from a range of charts and other virtualizations to act on their data. For instance, users can integrate reports, charts and re-usable panels to derive more insight from their data. In addition, there is also the option to tailor data for different use cases and users, such as business, security analysts, auditors, developers and operations teams, to facilitate their operations.

Centralized log and incident management

LogRhythm offers centralized log and incident management that helps users to collect, store and analyze logs/events from various sources for auditing, compliance, and forensic purposes. There are also case management and playbooks, which offer incident management functionalities to facilitate log and incident management processes.

Similarly, Splunk also provides a central log management feature that allows users to collect and store logs from various sources in centralized storage. Users can also encrypt the logs collected to prevent unauthorized access.

Advanced threat detection

Both LogRhythm and Splunk provide users with advanced threat detection capabilities. LogRythm does this by combining machine analytics and search analytics. These functionalities offer users a risk-based monitoring strategy that can automatically identify and prioritize attacks and threats.

Splunk also rides on the power of machine learning to detect advanced threats and other 1300+ out-of-the-box detections for frameworks such as MITRE ATT&CK, NIST, CIS 20 and Kill Chain.
