A Fluent Bit alternative built for security teams
Collect what Fluent Bit can't see.
Windows Event Log, ETW, file integrity, syslog, and network capture — one cross-platform agent, managed from a single console and delivered to any SIEM.

Fluent Bit vs. NXLog Platform at a glance

Why teams choose NXLog Platform
Windows done fully, not partially
Fluent Bit reads Windows Event Log channels. NXLog Agent goes further: complete EventData and UserData fields, SID-to-account resolution, XPath filtering, and remote collection over Windows Event Forwarding — from one agent, without extra tooling.
See below the Event Log
Debug and Analytical channels — DNS Server, Windows Firewall, kernel providers — are ETW-based and can't be collected as regular Event Log channels. The im_etw module reads ETW providers directly, with no intermediate trace files to parse.
Sources observability agents skip
File integrity monitoring, Windows Registry changes, passive packet capture, ODBC databases, Check Point OPSEC LEA, Linux Audit, and macOS ULS. NXLog Agent collects the sources SOC work depends on, not just container logs.
Management is in the box
Open-source Fluent Bit is configured one host at a time, and central fleet management for Fluent Bit agents is a separate commercial product (Chronosphere Telemetry Pipeline). NXLog Platform includes enrollment, configuration, monitoring, and updates for up to 100,000 agents per node.
Keep Fluent Bit where it's strong
Fluent Bit is a solid choice for container and Kubernetes log routing — keep it there if it serves you well. Run NXLog Agent across your Windows fleet, servers, and compliance scope, and let both deliver to the same SIEM.
Any SIEM, no lock-in
NXLog is vendor-agnostic. Deliver parsed, normalized events to Splunk, Microsoft Sentinel, Elastic, Google SecOps, or any syslog, HTTP(S), or Kafka destination — with built-in storage and analytics when you want retention outside the SIEM.

Value by Team
SecOps Engineer
Close the collection gaps that stall investigations. ETW, file integrity events, and complete Event Log fields turn "we don't have that data" into detections.
Detection Engineer
Hunt with richer telemetry: DNS analytical logs, Sysmon, PowerShell, Registry changes, and packet-level fields — parsed and normalized at the source.
Compliance & GRC Owner
Meet file integrity and audit-trail requirements without another tool: FIM on Windows and Linux, TLS-encrypted delivery, tamper-proof audit logs, and built-in retention.
Security Architect
One agent across six operating systems, on-premises deployment options, and no vendor lock-in — collection that fits the estate you run today.
What you get with NXLog Platform
One agent, every OS you run
A single cross-platform agent for Windows, Linux, macOS, BSD, AIX, and Solaris on x86/x64/ARM/PowerPC — collect, parse, and route at the source.
Windows telemetry in full
Event Log with complete fields and SID resolution, ETW providers, Windows Event Collector mode for agentless hosts, Registry monitoring, and Windows performance counters.
Security sources beyond the OS
File integrity monitoring, passive network capture with ICS protocol support, ODBC database collection, Check Point OPSEC LEA, Linux Audit, and macOS ULS.
Parse, filter, and enrich at the source
Parse syslog, JSON, XML, CSV, and key-value data, filter noise before it reaches your SIEM, and enrich events at the point of collection. Need custom logic? Extend the agent with Perl, Python, Ruby, Java, or Go.
Fleet management built in
Enroll, configure, monitor, and update agents from one console — with role-based access control, audit trails, and support for up to 100,000 agents per node.
Storage and analytics without add-ons
Built-in high-compression retention, fast search, and dashboards. Use them alongside your SIEM or on their own.

FAQs
For syslog, file tailing, and Windows Event Log forwarding — yes. NXLog Agent collects the same data and delivers it to the same destinations, then adds sources Fluent Bit doesn't offer: ETW, file integrity monitoring, packet capture, Windows Event Forwarding, and databases. Many teams keep Fluent Bit in Kubernetes and run NXLog everywhere else.
Yes. Both deliver to the same SIEMs and log platforms, so a phased rollout is safe: one destination, two collection layers, no downtime.
ETW providers (including DNS Server analytical logging and Windows Firewall), Debug and Analytical channels, remote collection over Windows Event Forwarding, Registry change monitoring, and file integrity events. Fluent Bit's Windows log inputs cover Event Log channels only.
Yes. NXLog integrates with OpenTelemetry pipelines, so adopting NXLog Platform doesn't take you off open standards. See the NXLog OpenTelemetry solution page for details.
No. Agent enrollment, configuration, health monitoring, and updates are part of NXLog Platform. With open-source Fluent Bit, central management comes from separate commercial tools.
Splunk, Microsoft Sentinel, Elastic, Google SecOps, OpenSearch, and any syslog, HTTP(S), or Kafka destination. NXLog Platform also includes its own storage and analytics if you want retention outside the SIEM.
