/ SecOps
Detect threats withoutdrowning 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.
/ The Problem
Why SIEM architectures fail under scale
Security environments can produce high and variable event volume. Measure duplicate, replayed, and low-value records before changing routing rules.
/ How it works
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
Measure duplicate reduction before ingestion
Debug logs suppressed deterministically at the source
Measure ingestion volume against a baseline
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.
/ Proven results
14.3 TB/day to 5.2 TB/day
Filter selected records before transfer, then measure SIEM ingestion and triage time against a customer baseline.
The Challenge
Security telemetry can include duplicates, debug output, and replayed events from failover mechanisms. Establish ingestion and triage baselines before changing filtering or routing rules.
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.
Evaluation scenario: compare ingestion volume and cost while validating every protected detection rule against customer-owned acceptance criteria.
14.3 TB to 5.2 TB daily
23 min to 5.6 min per alert
Zero detection rule changes

/ Common objection
"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.
/ Outcomes
Why deploy Expanso for SecOps
Lower SIEM cost
Filter selected records before transfer, then measure downstream volume and cost. 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. Configured metadata can support investigation and audit workflows; validate coverage across the complete chain.
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.
