Axoflow

Axoflow tackles a problem every security operations team quietly struggles with: SIEM platforms charge by data volume, but most of the telemetry organizations ingest is low-value noise, and syslog alone still accounts for over half of typical security data volume. Axoflow’s platform sits between data sources and the SIEM, automatically parsing, normalizing, enriching, and filtering security telemetry — including legacy syslog feeds — so that what reaches the SIEM is higher-quality and lower-volume, directly reducing licensing costs while (in principle) improving detection signal.

The company’s founder, Balázs Scheidler, created syslog-ng, the open-source log-management tool that has been a default component of Linux log infrastructure for over two decades, and previously founded Balabit, a security company that had a successful acquisition exit in 2018. That track record of building and successfully exiting an infrastructure security company in an adjacent space is a meaningful, independently verifiable credibility signal for a founder in this specific niche.

Founded in 2023 and based in Budapest, Hungary, Axoflow raised a €6.7 million ($7 million) seed round in January 2025 led by EBRD Venture Capital, with existing investors Credo Ventures and e2vc increasing their stakes, bringing total funding to roughly $10.6 million. As a young, small company (11-50 employees), Axoflow’s specific cost-savings and detection-quality claims for its own platform have not yet been independently validated by third parties, but the underlying problem it addresses — SIEM cost and data-quality management — is a widely acknowledged pain point across security operations teams.
