Npcap OEM for Commercial Use and Redistribution

We fund the Npcap project by selling Npcap OEM. This special version of Npcap includes enterprise features such as the silent installer and commercial support as well as special license rights allowing customers to redistribute Npcap with their products or to install it on more systems within their organization with easy enterprise deployment. The Npcap free license only allows five installs (with a few exceptions) and does not allow for any redistribution. We offer two commercial license types:

Npcap OEM Redistribution License: The redistribution license is for companies that wish to distribute Npcap OEM within their products (the free Npcap edition does not allow this). Licensees generally use the Npcap OEM silent installer, ensuring a seamless experience for end users. Licensees may choose between a perpetual unlimited license or an annual term license, along with options for commercial support and updates. [Redistribution license details]

Npcap OEM Internal-Use License: The corporate internal license is for organizations that wish to use Npcap OEM internally, without redistribution outside their organization. This allows them to bypass the 5-system usage cap of the Npcap free edition. It includes commercial support and update options, and provides the extra Npcap OEM features such as the silent installer for enterprise-wide deployment. [Internal-use license details]

Documentation

The primary documentation for Npcap is the Npcap User’s Guide. You can also refer to the README file on Github. The changes in each new release are documented in the Npcap Changelog.

Patches, Bug Reports, Questions, Suggestions, etc

Npcap bug reports can be filed on the Npcap Issues Tracker. Please test with the latest version of Npcap first to ensure it hasn’t already been fixed. It is also helpful if you search the current issues first to find out if it has already been reported. Then you can leave a comment on the existing issue rather than creating duplicates. Feature enhancement requests can be made on the tracker as well

Questions, comments and bug reports are always welcome. One option is the Nmap
development mailing list (nmap-dev). To subscribe, please visit:

Code patches to fix bugs are even better than bug reports. Instructions for
creating patch files and sending them are available here.

Bug reports for Npcap can also be filed on the Npcap bug tracker.
