Detect Threats Without Drowning in Log Noise
Stop bad data before it floods your SIEM. Validate, deduplicate, and enforce log integrity upstream so your security team focuses on real threats.
No tool replacement. No agent sprawl. Deploy in weeks.
Why SIEM Architectures Fail Under Scale
Your environment is growing faster than your SIEM can keep up. Cloud workloads increase 2-5x year over year. Endpoints scale to tens of thousands. APIs generate millions of events per hour. 20-40% of that volume is duplicate, replayed, or has zero detection value.
Enforce Security Telemetry at the Edge
Validates logs before they reach your SIEM. Not after.
Without Expanso
Every log forwarded to SIEM regardless of value
Duplicates and replayed events inflate volume
Debug-level logs consume correlation resources
Analysts buried in noise, real threats missed
Storage costs spiral with no performance gain
With Expanso
Duplicates reduced 70-80% before ingestion
Debug logs suppressed deterministically at the source
Ingestion volume reduced 40-80%
High-value security context preserved for correlation
Detection performance stabilized under growth
Deploy upstream
Expanso sits between your log collectors and your SIEM. No agent changes, no collector modifications. Your existing stack stays exactly where it is.
Validate and filter
Deterministic deduplication removes replayed events. Timestamp validation corrects ordering. Low-value debug telemetry is suppressed before it consumes correlation resources.
Protect your SIEM
Your SIEM receives trusted, structured, high-value telemetry. Correlation engines run faster. Detection rules fire on real events. Your team investigates threats, not noise.
14.3 TB/Day to 5.2 TB/Day
Top-25 U.S. regional bank reduced SIEM ingestion by 63% and cut triage time by 75%.
The Challenge
A top-25 U.S. regional bank ingested 14.3 TB of security telemetry daily. Roughly 73% of that volume was noise - duplicates, debug output, and replayed events from failover mechanisms. Average triage time per alert had stretched to 23 minutes, and the SOC team was losing analysts to burnout.
The bank needed to reduce SIEM costs without sacrificing detection coverage, and needed results before their next budget cycle.
What Changed
Expanso deployed upstream of the bank's Splunk instance in a 4-week pilot. Deterministic deduplication and timestamp validation reduced ingestion from 14.3 TB to 5.2 TB daily. Correlation engines ran faster on clean data. Average triage time dropped from 23 minutes to 5.6 minutes.
Full production rollout completed in 9 weeks. Annual savings reached $2.3M with zero changes to existing detection rules.

"We Already Have a SIEM..."
Exactly. Expanso does not replace your SIEM - it protects it. Your Splunk, Sentinel, Elastic, or Datadog instance stays exactly where it is. Expanso sits upstream and ensures your SIEM ingests trusted, structured, high-value telemetry instead of unfiltered noise.
Think of it as quality control for your security data pipeline. Better data in, better detection out.
Why Deploy Expanso for SecOps
Lower SIEM cost
Reduce ingestion volume 40-80%. Pay for signal, not noise. Works alongside Splunk, Sentinel, Elastic, Datadog, or any SIEM platform.
Faster triage
Analysts work with clean data. Triage time drops from 23 minutes to under 6. Correlation engines produce more accurate alerts when duplicates and noise are removed upstream.
No agent changes
Deploy without modifying existing agents, collectors, or detection rules. Runs anywhere your infrastructure runs - cloud, hybrid, on-prem, or edge.
Cleaner incident timelines
Validated, structured logs produce incident timelines you can trust. Full lineage supports compliance and audit requirements.
Less analyst burnout
Stop burying your team in noise. When duplicates disappear, analysts see real threats instead of replayed events. Focus shifts from filtering to investigating.
Scales with growth
Handles increasing log volumes without degrading detection performance. As your environment grows, Expanso keeps your SIEM costs and correlation speed stable.
Stop Paying to Ingest Noise
Validate before ingestion. Protect your SIEM. Detect faster.
