Your Splunk Bill Is 73% Noise
Most organizations ingest massive volumes of debug logs, health checks, and duplicates into Splunk. Expanso classifies and filters at the source - Splunk only ingests what matters.
Why Splunk Costs Spiral
The core issue is simple: Splunk charges by volume, and most of your volume is noise.
Volume-based licensing bleeds budget
Pricing That Punishes Growth
Splunk charges by daily ingestion volume. As your infrastructure grows, log volume grows - and every GB costs $2,500-$4,000 annually. Most of that volume is noise.
Debug logs nobody reads
73% Wasted Ingestion
Health checks, debug traces, and verbose application logs flood your indexes. Your security team wastes time filtering through noise to find actual threats.
License compliance anxiety
Overage Penalties Are Real
Splunk license overages trigger penalties and urgent scrambles to reduce volume. Teams spend weeks tuning forwarders instead of investigating security events.
Classify and Filter Before Splunk Sees It
Expanso deploys at your log sources. It classifies every log line, drops noise, aggregates verbose data, masks PII, and forwards only what your security and ops teams actually need.
How Expanso Reduces Splunk Costs
Six capabilities that cut your Splunk bill without sacrificing visibility.
Log classification at source
Know Before You Send
Every log line is classified by type and severity before leaving the source. DEBUG and TRACE logs drop immediately. INFO aggregates. WARN, ERROR, and security events forward in real-time.
Smart aggregation
Summarize Verbose Streams
Convert high-volume application logs into periodic summaries. Same operational visibility, 80% less Splunk volume. Summaries include key metrics, error counts, and trend data.
PII masking before Splunk
Compliance at the Source
Mask credit card numbers, SSNs, and PII before logs leave the source server. No post-ingestion redaction workflows. No compliance gaps.
Security event extraction
Priority Routing for SOC
Critical security events get extracted and fast-tracked to Splunk ES with enriched metadata. Your SOC sees threats immediately, not buried in noise.
Forwarder optimization
Replace Complex Configurations
Stop managing hundreds of props.conf and transforms.conf files. Expanso provides declarative filtering policies that deploy consistently across all sources.
Retention-aware routing
Right Index, Right Retention
Route high-value security data to long-retention indexes and operational data to short-retention indexes. Optimize storage costs without losing compliance data.

Real-World Impact

Regional Bank: $3.7M to $1.4M
A top-25 US regional bank was spending $3.7M annually on Splunk licensing. 73% of ingested logs were debug messages, health checks, and verbose application traces. Expanso classified every log at the source - critical security events forwarded in real-time, noise dropped before it reached Splunk.
O-RAN Telemetry: 47% Splunk Savings
A European telecom operator running O-RAN infrastructure generated massive network telemetry. Expanso filtered and aggregated telemetry at the RAN before forwarding to Splunk, eliminating redundant health checks and normalizing cell site data.
Why Expanso for Splunk
Deploy alongside forwarders
Install at your log sources without changing Splunk infrastructure. Works with universal forwarders and HEC.
No Splunk expertise required
Declarative policies replace complex props.conf and transforms.conf. Any engineer can manage filtering rules.
Prove ROI before commitment
Free tier processes 1TB/day. Run a proof of concept on your noisiest log sources and measure real savings.
Compliance stays intact
Security-critical logs flow unchanged to Splunk ES. Filtering only targets noise - your compliance data is untouched.

Frequently Asked Questions
Will filtering logs affect our security visibility?
No. Expanso's classification engine identifies and prioritizes security-critical events. WARN, ERROR, and security events are forwarded in real-time with full fidelity. Only noise - debug logs, health checks, and verbose traces - gets filtered or aggregated.
How does this compare to Splunk's own data management tools?
Splunk's Ingest Actions and DSP operate after data reaches Splunk infrastructure, so you're already paying for ingestion overhead. Expanso filters at the source before data ever reaches Splunk, eliminating the volume that drives licensing costs.
What happens during our Splunk license renewal?
Deploy Expanso before renewal to demonstrate reduced daily volume. Customers typically negotiate 40-70% lower license tiers. The Expanso investment pays for itself multiple times over in licensing savings alone.
Can we start with one log source and expand?
Yes. Most customers start with their highest-volume or noisiest log sources to prove value fast. The regional bank started with 12 sources and expanded to 247 in 9 weeks once they saw the volume reduction.
Does this work with Splunk Cloud?
Yes. Expanso sits upstream and is infrastructure-agnostic. It works with Splunk Enterprise, Splunk Cloud, and Splunk ES by filtering before data reaches any Splunk endpoint - HEC, forwarders, or direct ingestion.
