Axoflow · syslog-ng™ successor

AxoSyslog
Commercial Version

Collect, process, and route logs with the reliability, scalability, and flexibility you expect from syslog-ng™ — built for today’s complex, cloud-native environments, and backed by dedicated commercial support from the people who created it.

Why AxoSyslog CV

Drop-in replacement

Same architecture and config syntax, with easy upgrade options from syslog-ng™ and dedicated migration support.

Support from the creator

Our team’s decades of expertise ensure continued development and support for your deployments today and in the future.

Built for today’s environments

Support for containers and Kubernetes, new sources and destinations, and an improved data processing engine.

How it works

Built on syslog-ng™, upgraded for modern pipelines

FilterX: a robust toolkit for security data transformations

FilterX, developed by Axoflow, replaces syslog-ng™ filter statements, parsers, and rewrite rules with a syntax and rich set of operators similar to popular scripting languages — so you can filter, parse, manipulate, and rewrite variables and complex data structures like OpenTelemetry logs, protocol buffers, and JSON.

Modern, granular metrics

AxoSyslog CV collects detailed metrics about its host and the data it transfers. Host performance metrics, including disk buffer usage, packet loss, and event delay, help you find and troubleshoot pipeline issues fast; it can even create labeled metrics and counters based on message fields.

Scalability

Lightweight collectors that turn any host into a security data source

AxoEdge deploys a customized OpenTelemetry Collector to Windows and Linux hosts, managed centrally from AxoConsole. Label-based collection rules decide what each host collects — files, Windows Event Log, ETW, or journald — and provision it automatically, with no manual per-host setup.

Integrations

AxoSyslog CV makes it fast to plug your log pipeline into modern observability and cloud stacks, including Splunk Cloud, OpenTelemetry, Grafana Loki, Amazon S3, Azure Monitor / Microsoft Sentinel, Elastic / OpenSearch, ClickHouse, CrowdStrike, Google Pub/Sub, and Google BigQuery.
