Most of our products (e.g. ntop and PF_RING) are offered in source format under the GPL or LGPL licenses. Some of them that contain IPR (Intellectual Property Rights) (e.g. PF_RING ZC) that we want to share only with selected users, and thus we distribute them only in binary format. For other products for which we provide per-unit support we use a license, although the base product is released also in source format.
For binary products we apply various license models according to the product:
- nProbe, n2disk/disk2n, ntopng Pro: Per system license.
- PF_RING ZC: Per MAC (Mac Address) license.
- PF_RING (non ZC), ntopng (Community) and nBox: no license is necessary
