ntopng lists $0-$1499/year, but hidden costs like implementation and support add to the total as of November 2026. Key hidden costs: annual maintenance renewal: 25% of license cost if renewed within 1 month after expiration, or 75% for late renewals - adds $75-$375+/year for professional through enterprise l, hardware infrastructure costs: ntopng requires dedicated hardware or vms with 8-32gb+ ram depending on network size, which is an upfront expense that grows with traffic volume, storage costs for historical data: packet capture and flow data retention requires significant disk space, so storage infrastructure should be budgeted separately and scaled to your retention period.
