  • Limited cloud-based options. LogRhythm lags behind similar SIEM products in terms of offering cloud-native SIEM capabilities, as many competitors introduced cloud-native SIEM solutions much earlier than LogRhythm.
  • Confusing naming. The naming of product components and introducing functionality to prospective users by LogRhythm may prove to be confusing. An uncomplicated approach to naming products would offer prospective users more clarity.

What is Splunk?

Analytics-driven security

With Splunk, you can enhance security operations using analytics-driven security. Analytics-driven security allows your security operations center (SOC) to determine, prioritize and manage security events. This can be done through alert management, risk scoring, event sequencing and customizable visualizations and dashboards. Splunk’s analytics-driven security improves visibility all through your IT and security stacks, accelerates system query response time and augments the integration of security infrastructure.

Risk-based alerting

Risk-based alerting is Splunk’s answer to alert fatigue. This allows analysts to make risk attributions for users, systems, or other entities in the face of suspicious activity. These attributions are dispatched to the risk index instead of setting off alerts. As such, alerts are triggered only when risk exceeds certain thresholds. This risk-based approach also offers teams the opportunity to pivot resources to proactive functions from traditionally reactive functions in the security operations center.

Contextual threat detection and incident response

Splunk provides you with all the investigative tools you might require for a quick response. These tools represent a modern SIEM where you can compile all the context needed in one view to carry out quick investigations and receive quick responses. Users are empowered to handle newly discovered and existing threats quickly using contextual threat detection and incident response.

End-to-end visibility

Splunk’s SIEM tools promise visibility across users’ hybrid environments using multi-cloud security monitoring. Splunk offers out-of-the-box Cloud Security Monitoring content to simplify monitoring, analyzing, investigating and detecting threats across Microsoft Azure, AWS, GCP and other multi-cloud environments.

  • Pricing and contract flexibility. Splunk’s pricing and contract flexibility garnered lower scores compared to other SIEM solutions, including LogRhythm. You can compare its pricing review ratings on the Gartner Peer Insights
  • No fully cloud-native security operations suite. Splunk Enterprise Security is part of Splunk Cloud. However, if you seek a fully cloud-native option that includes Splunk User Behavior Analytics (UBA) and Phantom, you must ask Splunk whether hosted options are available in your geography.
  • Splunk Cloud geographic support. Customers outside of North America, Europe and Asia, such as in Latin America, the Middle East and Africa, need to contact Splunk to find out whether they can receive adequate support.
