Axoflow + CrowdStrike Next-Gen SIEM: Lower Ingest, Longer Retention
Overview
CrowdStrike Falcon is the endpoint platform of choice for many security teams, and Next-Gen SIEM is the natural next step: one vendor, one console, and detections already tuned for Falcon data. The business case holds until two costs show up: keeping Falcon data beyond the standard retention window, and bringing in everything that isn’t Falcon data, like firewall, network, and cloud logs.
Axoflow works on both sides. It copies CrowdStrike’s own data into long-term, searchable storage in AxoLake, and it classifies, reduces, and normalizes third-party data before it reaches Next-Gen SIEM. You end up with a SIEM that holds what your detections need, and an archive that holds everything else for years.

Why It’s Great
Less Third-Party Data, Same Detections
AxoRouter automatically classifies and parses each source as it arrives, with 300+ parsers out of the box. It keeps the fields and events your detections use, drops empty and redundant data, and sends normalized events to Next-Gen SIEM.
Years of Falcon Data, Searchable in Minutes
A built-in CrowdStrike Falcon Data Replicator (FDR) connector turns CrowdStrike’s bit-for-bit data copy into a compressed, indexed archive in AxoLake. There’s no cold tier to thaw: analysts search years of Falcon data directly from AxoConsole.
Direct HEC Delivery
AxoRouter sends data straight to the Falcon Next-Gen SIEM HTTP Event Collector (HEC), removing the intermediate collector host often used to forward syslog into CrowdStrike. One less box to run and troubleshoot.
Flexible Deployment and Storage
Run AxoConsole as fully managed SaaS or self-managed. Keep AxoLake storage Axoflow-hosted, in your own S3 bucket, or fully on-prem for air-gapped environments.
Routing by Value
Alerts and interactive logs go to CrowdStrike. High-volume, low-value telemetry goes only to AxoLake, still searchable and ready to rehydrate when an investigation needs it.
Rehydration on Demand
Bring back only what you need. When an investigation needs older events, search AxoLake with federated search, then send only the matching events back to CrowdStrike Next-Gen SIEM.
Use cases
Keep Falcon Data for Years Without the SIEM Bill
- Let Falcon agents keep reporting natively to CrowdStrike, and use AxoRouter to copy Falcon data via FDR into AxoLake for long-term retention.
- Keep 30 days, 90 days, a year, or up to 7 years for regulated and government environments.
- Search years of history from AxoConsole, stored as open Parquet files that are indexed as they land.
Cut Third-Party Ingest Before It’s Billed
- Route Palo Alto, Fortinet, Cisco, Meraki, Infoblox, and cloud logs through AxoRouter before they reach Next-Gen SIEM.
- Keep security-relevant events and strip empty and redundant fields. In one test against a live CrowdStrike tenant, reducing Azure Event Hubs data cut bytes sent by 82%.
- Leave out the raw message copy from normalized HEC events to trim every payload.
Fill the Collection Gap
- The Falcon agent sends security-relevant events in batches; it doesn’t stream Windows event logs or syslog.
- Axoflow collects from Windows and Linux hosts, cloud services, and appliances via syslog, OpenTelemetry, HTTP, and more.
- Disk buffering on AxoRouter protects data during network outages and peak loads.
Feed AI-Ready Data to CrowdStrike and Beyond
- Axoflow sends parsed, classified, and normalized records that make detections and dashboards more accurate.
- AI agents perform noticeably better on pre-indexed data in AxoLake than on raw logs.
- Send the same events to multiple destinations, each optimized individually, which makes migrations and parallel SIEM setups straightforward.
True Integration with CrowdStrike Next-Gen SIEM
Unlike tools that simply forward your data as-is to CrowdStrike, Axoflow does:
- Classification and parsing
Identifies and parses logs from hundreds of products in real time, enabling effective reduction.
- Reduction before ingestion
Removes redundant events and fields so you pay only for detection-relevant data. - Normalization for the destination
Sends normalized events to the Falcon Next-Gen SIEM HEC destination, with dynamic index and source type settings. - FDR-based archiving
Turns Falcon Data Replicator output into a compressed, searchable archive in AxoLake. - Verifiable results
Shows input versus output per flow, so you can check the numbers against what CrowdStrike reports for the same period.
One Pipeline for Both Sides
- One AxoRouter, one console
Storage and reduction run on the same AxoRouter, managed from one AxoConsole, so they aren’t two separate projects. - Everything archived, only the essentials billed
FDR and third-party logs land in AxoLake; only the reduced, detection-relevant stream goes on to CrowdStrike over HEC. - Scale your infrastructure as needed.
Optimize storage and ingestion costs
Axoflow’s storage solutions keep CrowdStrike focused on endpoint detection, so it doesn’t also have to be your most expensive log archive:
- Predictable retention costs with AxoLake: pricing comes down to average GB per day and retention in days, so a multi-year Falcon archive becomes a predictable line item, not a reason to delete data.
- A 1.7 GB sample of FDR data lands as 275 MB on disk: around 8x compression, measurable in each router’s Stores view.
- Expect around 40% reduction with minimal tuning, 25–60% across a typical CrowdStrike source mix, and around 70% where firewall and cloud logs dominate.
- Flat pipeline pricing in tiers by average GB per day, fixed for the contract term, with no charge per router or agent.
- Set retention by requirement, not budget: keeping 1 to 7 years becomes a storage decision instead of a SIEM license decision.
- Measure a full weekday and compare Axoflow’s output with CrowdStrike’s ingest numbers over 24 hours, since weekly averages undercount.

FAQs
How does Axoflow integrate with CrowdStrike Next-Gen SIEM?
Axoflow works on two paths. Falcon data is copied via Falcon Data Replicator (FDR) into AxoLake using a built-in connector and a ready-made flow, where it’s compressed and searchable within minutes.
Third-party data passes through AxoRouter, which classifies, parses, reduces, and normalizes it, then delivers it directly to the Next-Gen SIEM HTTP Event Collector (HEC). Falcon agents keep reporting to CrowdStrike natively.
How does Axoflow reduce ingestion volume without losing critical data?
Classify and parse in the pipeline: AxoRouter identifies each source automatically, so it knows which fields matter for detection.
Keep what detections use, drop the rest: flows keep security-relevant event categories and strip empty and redundant fields.
Trim the payload: normalized HEC events can leave out the raw message copy.
Route by value: detection-relevant data goes to CrowdStrike, while high-volume, low-value telemetry goes to AxoLake, where it stays searchable and can be rehydrated.
Verify with metrics: Axoflow shows input versus output per flow, so you can match results against CrowdStrike’s own ingest figures.
Should Falcon agent data go through Axoflow?
No. Let Falcon agents report natively, where detection runs and agent data is covered within the standard retention window. Use FDR to copy that data into AxoLake for long-term retention, and route third-party sources through Axoflow before they reach CrowdStrike.
How long can I keep Falcon data?
As long as your requirements demand, from 30 days up to 7 years, in Axoflow-hosted storage, your own S3 bucket, or fully on-prem.
