Current public revisions are licensed under GPL-3.0-or-later. A separate negotiated commercial path is available for proprietary integration, OEM or white-label distribution, closed-source redistribution, private branches, and contractual engineering services. The commercial notice grants no additional rights by itself.

ARSVIN can capture and transmit raw Ethernet frames. Use live features only under explicit authorization and an appropriate test boundary. The software is not calibrated deterministic real-time equipment, a formal IEC 61850 conformance platform, a functional-safety system, cybersecurity-certified equipment, or proof that another IED consumed or acted on a multicast stream.
