Splunk Enterprise 10
Splunk Enterprise 10 is the core Splunk platform used to collect, index, search, analyze, and visualize machine data.
As a sysadmin, think of it as the central log/data analytics platform where you ingest data from servers, applications, network devices, cloud services, security tools, and more.
Main uses
- Log collection and indexing
- Search and correlation across machine data
- Dashboards and reports
- Alerting
- Operational monitoring
- Troubleshooting infrastructure and applications
- Data onboarding through forwarders, APIs, syslog, HEC, etc.
Typical components
Splunk Enterprise deployments can include:
- Search Head Where users run searches, dashboards, alerts, and reports.
- Indexer Stores indexed data and handles search execution over indexed events.
- Universal Forwarder / Heavy Forwarder Collects and forwards logs from systems to Splunk.
- Cluster Manager / Deployment Server / License Manager Used in larger distributed deployments.
The 10.x version line represents a newer major release of the Splunk Enterprise platform. Major releases usually include improvements around:
- Platform performance
- Scalability
- Security updates
- UI and administration improvements
- Compatibility changes
- Updated app/framework support
- Potential deprecations or breaking changes
Splunk Enterprise Security 8
Splunk Enterprise Security, often called Splunk ES, is a premium security application that runs on top of Splunk Enterprise.
Enterprise Security 8 is a major version of that security-focused app.
It turns Splunk into a SIEM: Security Information and Event Management.
Main uses
Splunk ES is used by SOC and security teams for:
- Threat detection
- Security monitoring
- Incident investigation
- Risk-based alerting
- Correlation searches
- Notable events
- MITRE ATT&CK mapping
- Asset and identity context
- Threat intelligence
- Compliance and reporting
- Security dashboards
Key ES concepts
Notable Events
Instead of just basic alerts, ES creates notable events that analysts triage in the Incident Review interface.
Example:
Multiple failed logins followed by successful login from same source
Correlation Searches
These are scheduled searches that detect suspicious behavior.
Example:
index=wineventlog EventCode=4625
| stats count by src_user, src_ip
| where count > 10
Risk-Based Alerting
ES can assign risk scores to users, systems, IPs, or other entities.
Example:
User john.doe gets:
+20 risk for impossible travel
+30 risk for suspicious PowerShell
+40 risk for malware detection
Total risk = 90
Once risk crosses a threshold, ES can create a higher-confidence notable event.
Data Models
ES relies heavily on Splunk’s Common Information Model, or CIM, and accelerated data models such as:
- Authentication
- Network Traffic
- Endpoint
- Malware
- Change
- Web
- Intrusion Detection
This means your logs need to be normalized correctly.
Relationship between the two
Splunk ES requires Splunk Enterprise or Splunk Cloud Platform underneath it.
Simple hierarchy:
Splunk Enterprise 10
└── Splunk Enterprise Security 8
So:
| Product | Role |
|---|---|
| Splunk Enterprise 10 | Core data platform |
| Splunk Enterprise Security 8 | SIEM/security app running on Splunk |
You can run Splunk Enterprise without Enterprise Security, but you cannot use Enterprise Security without a Splunk platform underneath it.
Example scenario
Let’s say you collect these logs:
- Windows Event Logs
- Linux auth logs
- Firewall logs
- VPN logs
- EDR logs
- DNS logs
- Proxy logs
- CloudTrail logs
With Splunk Enterprise only
You can search manually:
index=wineventlog EventCode=4625
| stats count by Account_Name, src_ip
| sort - count
You can build dashboards and alerts yourself.
With Enterprise Security
ES gives you prebuilt SIEM functionality:
- Security dashboards
- Incident Review
- Correlation searches
- Risk scoring
- Threat intel framework
- Asset/user enrichment
- Investigation workflows
- Security posture views
So ES is more specialized and SOC-oriented.

In practical sysadmin terms
If you are managing infrastructure:
- Splunk Enterprise 10 helps you centralize logs and troubleshoot systems.
- Splunk ES 8 helps your security team detect attacks, investigate incidents, and run SIEM operations.
A common deployment looks like:
Servers / Firewalls / Cloud / Apps
↓
Universal Forwarders / Syslog / HEC

Enterprise Security Search Head
Important planning points
Before deploying ES, you usually need:
- Proper data onboarding
- Correct sourcetypes
- Correct indexes
- Reliable timestamp parsing
- CIM normalization
- Field names must match Splunk CIM expectations.
- Data model acceleration
- Required for ES performance.
- Sizing
- ES can be resource-intensive.
- Search head CPU/RAM and indexer performance matter.
- Good asset and identity data
- Hostnames, users, departments, criticality, categories.
- Tuning
- Correlation searches need tuning to reduce false positives.
