Like Splunk, Sumo Logic automatically populates the search bar with parameters and data sources to save you time remembering search functions. If you are new to working with searches and queries, Sumo Logic offers a number ofuseful cheat sheetswhich contain all the common search functions for querying your data.

To create meaningful alerts, you must first create a query based on that alert. Once this query is recorded, you can specify a condition to trigger this alert and set a threshold. You can use an outlier operator to position your boundaries to expand and contrast with web traffic. Creating alerts is easy as long as you've written your query correctly. Notifications can be sent via email or webhook via third-party integrations.


  • Supports multiple environments (Linux, Windows and Mac OS)
  • Easy installation: use wizards to speed up installation and add-ons

Splunk is a SIEM tool that aims to provide enterprise-grade information security and log management for customers. The Splunk platform offers a wide range of services and features, including insider threat detection, forensic auditing, and even fraud detection. While Splunk mostly advertises that it is cloud-based, there is an option for an on-premise installation. This can be done through the VMware infrastructure, but compared to deploying in the cloud, it can take a significant amount of time to ensure that requirements are met and the correct resources are allocated.

Main features:

  • On-premise or cloud platform
  • data analytics platform
  • records management service
  • SIEM option
  • Alert creation mechanism

Like most SIEM products, Splunk uses its own agent called an indexer to collect data. This indexer requires some configuration, depending on the operating system environment in which it is installed. Once the indexer is configured and installed, you can configure Splunk to start receiving data by accessingSettings > Forwarding and Receivingand enter your agent's listening port.

The setup process can sometimes be complex and involves redirects and installing "apps" designed to simplify the onboarding process and prevent misconfigurations. Depending on the complexity of your environment and the number of domain controllers and servers you need to define policies for, integration time can vary. Splunk's support team has a professional services department that can help with integration, data migration, and configuration.

After the initial onboarding process, Splunk's ease of use really starts to shine. Splunk has some of the most intuitive and flexible dashboards in the SIEM space, allowing drag-and-drop editing via the view editor and XML configuration to make changes on the fly. Dashboard dashboards are designed for teams, giving you the ability to create specific views based on departments or groups. This ensures that no team is overwhelmed with information that is not relevant to their tasks.

Researching Splunk can be a complex but rewarding task. Splunk uses its own query processing language (SPL) to filter and sort data. This SPL can sometimes have a steep learning curve, but it allows for the generation of complicated and complex queries. One of the most powerful features of Splunks SPL is the ability to view your survey data in real time. Whether it's a numerical value in a graph or a geolocation tag, this information can be visualized as you develop and refine your query.

You can create notifications in Splunk based on a query by simply typing that query as a search and clickingSave asbutton and selectionAlarm. From here, an alert workflow is created that allows you to select the conditions for triggering the alert, as well as the permission level and schedule for running the alert script. Once saved, all notifications will automatically appear on your notification panel, where you can get an overview of their current status and how often they were triggered.


  • It has a great interface for viewing data and monitoring live metrics
  • Supports physical and virtual environments
  • It offers excellent support to companies and a wide range of integrations.


  • More geared towards corporate customers

Splunk has a bigger community and more features.Splunk took its profits and reinvested them heavily in the Splunk platform. This has allowed the platform to achieve "hockey stick" growth while maintaining a competitive advantage over other SIEM tools.

Features like Augmented Reality (Splunk AI) allow you to visualize data in real-time, and new developments in the Splunk mobile app give data a new level of versatility compared to other platforms. Although Splunk is not open source, it still has a large community that helps other users answer questions, share best practices, and request new features.

Splunk has five different support models, from basic documentation access to premium 24/7 support with a minimum response time of 30 minutes.

While not all companies require this level of granularity in their support contract, Splunk has taken the time to create these plans to better serve our customers.

Sumo Logic has a smaller learning curve.If you don't have the budget or want to delve into proficiency with a SIEM, Sumo Logic is an easier option.

Splunk's SPL search engine may be powerful, but it adds many layers of complexity to the mix that smaller companies may not even need to use.

Splunk has more third-party integrations.While both platforms have the ability to use webhooks and API integrations, Splunk has many more plugins and features out of the box. Currently, Splunk has over 600 different types of apps and plug-ins that extend and enhance the platform's usefulness.
