Elastic vs. Splunk: Key differences

Elastic

Splunk

User experience

Fully unified user interface for observability and security on the same Elastic Search AI Platform.
Splunk's fragmented offerings include Splunk Enterprise, Splunk Cloud, Splunk Enterprise Security, Splunk SOAR, Splunk User Behavior Analytics, and Splunk Observability Cloud. Splunk's acquisitions don't integrate well, creating siloed solutions that are an obstacle to speedy problem resolution.

Insights

Advanced search and generative AI capabilities, including vector search, natural language processing (NLP), a generative AI Assistant powered by RAG, AI-powered Attack Discovery, an open library of ML models, and easily customizable ML jobs for any type of data or use case.
Lack of advanced AI and analytics capabilities, hampered by disjointed data sets.

Pricing

Simple pricing based only on the resource you use. A single Elastic SKU provides all features across observability, security, and search.
Each Splunk product has a different pricing model. And achieving full-stack observability and security requires purchase of multiple solutions and add-ons. Volume and compute-based pricing options add further complexity and costs.

Storage and performance

A unified data store for all data (logs, events, metrics, traces, profiling, business data, etc.) with fast access, even from cost-effective archival tiers (without rehydration). Rapidly analyze all of your data — no matter where it's located.
Splunk's disjointed solution architecture fragments data sets (e.g., log data siloed from metrics and traces). Further, Splunk's data tiering approach results in a higher cost-to-performance ratio than the Elastic equivalent, with the lowest-cost tiers requiring rehydration (24hr) to access.

Query language

Elastic's piped query language and engine, ES|QL, addresses many of the previous constraints around JSON-based DSL queries.
Splunk's piped query language, SPL, allows you to search and manipulate Splunk data.

Splunk Replacement for Data Management

Elastic vs. Splunk: Cold truth about data tiers

To be successful with Splunk — you need dedicated resources plus a near-term and long-term storage strategy. Many Splunk customers struggle to align their evolving business needs to the correct data storage option.

But with Elastic, you get simple, straight-forward, and centralized data management — with no hidden agenda or costs. Search across geos in milliseconds, not seconds. Query archival tiers in minutes, not hours. Compare the capabilities of Splunk versus Elastic data tiers so you can make an informed, cost-effective decision.

Splunk Replacement for Logging

Elastic Observability

In Splunk, logs are fragmented and separated from traces and metrics. Teams cannot see the full picture on one screen. Take the first step by consolidating your logs on Elastic and gain the benefits of a unified observability solution built with Search AI. With end-to-end visibility across all your logs, metrics, and traces, correlated and in context, you can decrease mean time to resolution (MTTR) and lower total cost of ownership (TCO).

Splunk Replacement for SIEM

Elastic Security

Many legacy SIEMs, like Splunk, weren't built to adjust to your business' needs. AI-driven security analytics is critical to adapt to the latest breed of threats. Accelerate SecOps workflows and reduce risk with Elastic. You get limitless scalability, advanced analytics, and generative AI insights, to eliminate blind spots, strengthen defenses, and mitigate the global cyber skills shortage. The AI revolution is here — and SIEM will never be the same.
