Splunk Vs Elk

If companies didn’t use log management systems, they would have very limited visibility into internal infrastructure activity that might cause or suggest a security problem. Let’s take a look at the differences and similarities between the two industry giants, Splunk and ELK (also known as BELK or Elastic Stack), in the business world.

The great majority of today’s IT systems generate comprehensive logfiles that record every facet of everyday operations, from when and by whom resources were accessed to what actions were taken and whether or not errors were encountered. It’s simple to imagine a scenario in which a company’s infrastructure is completely swamped by the massive amounts of logfiles it produces. Businesses may utilize log management and analysis technologies to sift through this data mountain and find actionable insights.

What is Splunk?

Splunk, a Security Information and Event Management (SIEM) system, is a log management and analysis platform commonly known as the “Google for logfiles.” By centralizing the logfile data collected from a wide variety of systems and devices across an IT environment, security information and event management (SIEM) enables operators and infosec professionals to perform higher-order security analyses and assessments about the collective state of their systems from a single interface.

There are several SIEM systems available, but Splunk has emerged on top because to its Google-like search capabilities. The platform employs a specialized search language called Search Processing Language (SPL) to facilitate navigation and contextual searches across enormous data sets.

Splunk’s extensive app and plugin ecosystem allows for even more flexible deployment across industries and data kinds.

What is Elastic/ELK?

The previously known ELK Stack is now known as the Elastic Stack. Elasticsearch, Logstash, and Kibana create a potent trinity of open-source software.

For log analysis, this is the most popular trio of tools used in a wide variety of IT fields. Thanks to Elk stack’s centralized logging capabilities, the cause of any web server’s or application’s performance issues may be pinpointed with relative ease.

It collects all the logs in one location, making it simple to look for trends that could suggest an issue affecting many platforms.

  • Data is collected using a pipeline tool called Logstash. The ELK stack’s first layer is responsible for sending information to Elasticsearch. It gathers information from several sources at once and makes it simple to incorporate into other applications.
  • Elasticsearch: Elasticsearch is a Lucene-based NoSQL database that uses RESTful APIs. It’s a decentralized search and analytics platform with extensive configuration options. Key features include horizontal scalability, simplicity of deployment, exceptional dependability, and controllability. It keeps everything in one place for easy document searches and allows advanced queries for comprehensive investigation.
  • Kibana is a tool for visualizing data sets. It simplifies data access for developers by providing a visual representation of Elasticsearch records. The results of advanced Elasticsearch queries may be shown in a variety of ways on the Kibana dashboard, including via a variety of interactive visualizations, geolocation data, timelines, and graphs.

Splunk vs. ELK/Elastic Stack


  1. Search Capabilities

  • Splunk’s powerful search capabilities may be attributed to the SPL (Splunk Processing Language).
  • The engine at the heart of ELK, Elasticsearch, allows for sophisticated full-text searching using a DSL.
  1. Efficiency and Ease of Use:

  • The natural-sounding query language and intuitive interface are two key reasons for splunk elasticsearch
  • Though more difficult to implement initially, the ELK/Elastic Stack ultimately affords more adaptability and scalability.
  1. Help for the Community:

  • From user groups and wikis to forums, the Splunk community is always bustling with activity.
  • The ELK/Elastic Stack has a robust open-source community behind it, however it may be lacking in features compared to Splunk.
  1. Release Rate

  • Splunk is a subscription service with frequent feature and bug fix releases.
  • Elastic has been under development for quite some time, but because to its open-source status, the rate at which new features and bug fixes are introduced varies.
  1. Pricing and Support

  • Splunk runs on commercial software. Provides a number of pricing options, including tiered plans with varying prices depending on the amount of data used.
  • The ELK/Elastic Stack’s foundational pieces are available at no cost as open-source programs. Commercial versions of Elastic, which include more bells and whistles and a dedicated support team, are also available.
  1. API and Extensibility

  • Splunk’s extensive collection of application programming interfaces (APIs) allows it to integrate with a broad variety of other applications.
  • While ELK/Elastic Stack may need more setup than Splunk, its application programming interfaces (APIs) make integration easy and enable for specialized software to be built.
  1. Third-Party Service Integration:

  • Splunk’s Splunkbase marketplace is a good location to find third-party connectors and plugins.
  • While the Splunk environment has stagnated, the elk elasticsearch ecosystem is thriving, with new connections and plugins being created on a regular basis.
  1. Companies that Use It

  • Splunk has a wide range of applications outside of IT and security, including in the financial sector and the medical industry. Used by both large corporations and tiny startups.
  • Startups, IT companies, and other businesses all like ELK/Elastic Stack as an affordable log management and analytics solution.
  1. Learning curve

  • The learning curve for Splunk course is low because of its intuitive interface and basic search language.
  • The elk elastic stack has a longer learning curve than some other solutions, especially for those who are not experienced with open-source platforms or who want extensive customization.

To sum up, when it comes to keeping and analyzing log data, both Splunk and ELK/Elastic Stack are solid, enterprise-grade solutions. Since the total cost of ownership for these technologies might be prohibitive for certain firms, Splunk and Elastic have created hosted versions.

Which One Is Better, ELK Stack or Splunk?

Consider your company’s requirements and other aspects before settling on the ELK Stack or Splunk. Access to resources (both financial and informational) is also important.

If your business has to process information from several sources, the free and open-source ELK Stack is a great choice. However, Splunk really comes into its own when dealing with the massive amounts of data generated by machines. The solution is best suited for forward-thinking businesses that put a priority on continuous monitoring and in-depth analysis.

Think about the team’s present abilities and limitations, as well as the resources it has access to. It may not be easy to set up an ELK Stack from start. Conversely, Splunk’s user-friendly design and in-app search support make it a great fit for groups whose members have diverse levels of technical expertise.

Users incur no costs while using the ELK Stack since it is based on open source and free software. Additional Elastic features and enterprise-level support can be available for a price. However, Splunk offers a commercial pricing model that takes data volume and user count into consideration.


This article compares and contrasts the ELK Stack with Splunk to help you choose the right one for your needs. Your organization’s specific needs and available resources will determine whether of Splunk and Elastic/ELK is the better fit. If you need a robust but user-friendly solution for managing and analyzing a wide range of logs, Splunk may be your best option. Because of its adaptability and extensibility, Elastic/ELK may end up being a better fit for your needs.
