Talk to a mentorSame question, two platforms: query side by side
Find failed logins and group by source IP — the same detection in SPL, in KQL and in the shared ingestion model behind both.
# Top source IPs with failed logins in the last 24h index=linux sourcetype=linux_secure "Failed password" | rex "from (?<src_ip>\\d+\\.\\d+\\.\\d+\\.\\d+)" | stats count as failed_attempts by src_ip, user | where failed_attempts > 5 | sort - failed_attempts | head 20 # Alert when a single IP exceeds 20 failures in 5m index=linux sourcetype=linux_secure "Failed password" | bin _time span=5m | stats count by _time, src_ip | where count > 20
SPL reads like a pipeline: search → extract → transform → sort. It is expressive and consistent across Splunk search, dashboards, alerts and Enterprise Security.
# Kibana Discover / Elastic Security — KQL event.outcome: "failure" and event.category: "authentication" and @timestamp >= now-24h # Aggregation in Elasticsearch query DSL GET logs-auth-*/_search { "query": { "bool": { "filter": [ { "term": { "event.outcome": "failure" } }, { "range": { "@timestamp": { "gte": "now-24h" } } } ] } }, "size": 0, "aggs": { "by_src_ip": { "terms": { "field": "source.ip", "size": 20 } } } }
Kibana filters with KQL for speed, and Elasticsearch handles aggregations, alerting and dashboards. You can drop into the full DSL when you need more control.

Frequently asked questions: Splunk vs ELK Stack
Answers to what freshers and working professionals ask us most.
Which pays more in India in 2026: Splunk or ELK Stack?
Pay depends far more on your skills, certifications and company than on the platform label. Both are paid in a similar band — indicatively ₹3–6 LPA for freshers and ₹6–12 LPA with 2–4 years of experience. Splunk skills often command a small premium in large enterprises and banks that have already invested in the licence, while strong Elasticsearch and Kibana engineers are in high demand in product companies and managed-security services.
Is ELK Stack easier to learn than Splunk for a beginner?
Usually no for the very first weeks. Splunk is a single platform with one query language (SPL) and one UI, so beginners become productive faster. ELK is a stack of separate components — Elasticsearch, Logstash, Kibana and Beats — and each one has its own configuration and concepts, which adds to the learning curve even though it is free to install.
What is common between Splunk and ELK Stack?
Both are used for log aggregation, search, dashboards and alerting, and both are commonly deployed as a SIEM in SOCs. Both ingest logs from servers, network devices and cloud services, both support rich search queries and both need careful index design, retention planning and access control to work at scale.
Can I switch from ELK Stack to Splunk later in my career?
Yes, and it is common in large enterprises that run both. The mental model — ingest, parse, index, search, alert — is the same. What changes is the query language (KQL/DSL to SPL), the licensing model and the app ecosystem. An ELK engineer comfortable with Elasticsearch and Kibana can usually become productive in Splunk within 4–8 weeks of focused practice.
Which one should a fresher choose for placements?
If you are targeting large enterprises, banks or managed-security providers that already run Splunk, learning Splunk with a Splunk Core Certified User certification opens doors quickly. If you want the widest range of roles across product companies, startups and security teams, ELK is more accessible because you can install it for free and build real projects. Many SOC analysts end up using both.
Is Splunk expensive compared to ELK Stack?
Yes, Splunk is a commercial product and its licence is based on data volume ingested per day, which can get costly at scale. ELK Stack is open source (with paid Elastic Cloud and enterprise features), so you can start for free but carry more operational cost yourself. This cost difference is exactly why many teams use Splunk for high-value security data and ELK for broader, high-volume log analytics.
How long does it take to become job-ready in Splunk or ELK Stack?
With regular practice, most learners need 3–5 months: Linux, networking, log formats (syslog, JSON, Windows Event Log), the query language, dashboards, alerting and ingestion pipelines, plus 2–3 portfolio projects. Splunk has a slightly faster first step because the platform is unified, but both require hands-on practice to become job-ready in a SOC or platform role.
How can Uncodemy help me learn Splunk or ELK Stack?
