Npcap OEM Edition—Internal-use License

Npcap is the Nmap Project's packet capture (and transmission) library for Windows. While Npcap has many end users who simply use the free/demo version, we fund the Npcap project by selling the enhanced Npcap OEM Edition. This special version includes enterprise features such as the silent installer and commercial support as well as special license rights allowing customers 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. Key features include:

This page describes the Npcap OEM internal-use license for companies and other organizations that wish to use Npcap themselves but won't be redistributing Npcap outside of their organization. Companies which wish to redistribute Npcap OEM (such as within their products) should visit the Nmap OEM redistribution license page instead.

Npcap OEM releases are always made in conjunction with Npcap free/demo releases, and the version numbers are the same. Since Npcap OEM is almost identical to the free/demo Npcap, more product details are available from the Npcap public pages and we won't try to reproduce all of that here.

Internal-use License Prices & Terms

We offer Npcap OEM as a perpetual license to the current version, with the option to purchase maintenance (updates and support) for 1 or more years. Maintenance is optional, but highly recommended because it extends the perpetual license to include all new versions released during the maintenance period. And Npcap is under very active development with dozens of feature enhancements, bug fixes, and performance improvements made every year. Maintenance also includes commercial support whenever you need it. The license also includes priority with bug fixes and feature requests as well as funding continued development and improvements in Npcap. The prepaid three and five-year maintenance terms allow you to lock in the current prices as well as an additional discount of 10% (3-years) or 20% (5-years). They also save you the effort of annual renewals. You can use Npcap for your own internal software and/or for Wireshark or any other software. An install would be on an individual computer or virtual machine or docker container or cloud server or similar.

Please note that Npcap OEM does not include any license management or DRM components. Those can be risky if they go wrong, so we rely on companies to track their own install numbers (or just buy the enterprise unlimited license). The rights Npcap OEM redistribution license customers enjoy are spelled out in the sample license certificate. This includes support, indemnification, warranty, updates, etc. A filled-out version containing software download credentials is provided for each purchase.

Purchase Process (Internal-use License)

To buy an Nmap OEM Internal-use license, send a message to sales@nmap.com with the following information:

  1. Your company/organization name. Resellers should include the end user's name as well.
  2. Which license sizeyou want. This would be either unlimited installs, 5,000 installs, 1,000 installs, 500 installs, 250 installs, or 100 installs. Some organizations buy more than one license if they need more seats or if they want individual business units to have their own allocations.
  3. Do you want 5 years of initial updates and support (with the 20% prepayment discount), 3 years of maintenance (10% discount) or just the first year of maintenance? We recommend buying at least the first year of maintenance since Npcap OEM is under very active development with dozens of feature enhancements, bug fixes, and performance improvements made every year. Maintenance also includes commercial support whenever you need it. Still, you know your needs better than we do and can choose no maintenance at all if that's what you want. You can purchase maintenance later by requesting a quote from sales@nmap.com, but prices may be higher, and it would have to start on the original license date. After all, a company that purchases maintenance 2 years after their original license immediately benefits from all Npcap improvements made during that period and can immediately make any support requests already accrued.
  4. Would you like an invoice that you can pay directly (using credit card, wire transfer, check, direct deposit, etc.) or a quote which you can use internally within your company to generate a purchase order for us to invoice against?

Once we receive your request, we will send a formal quote/invoice with an instant credit card payment link along with offline payment instructions for wire transfer, ACH direct deposit, or checks. Or issue a PO for us to invoice against.

As soon as payment or a purchase order is received, we will activate your license and send you the following:

Downloading and Installing Npcap OEM

Current licensees can find the Npcap OEM installer itself in this distribution directory. If you don't remember your company's username and password, please contact sales@nmap.com. Be sure to download the latest version unless you specifically require an older one. Note that updating Npcap to later versions requires a maintenance (support and upgrades) subscription. If you aren't sure whether you have an active maintenance subscription, email sales@nmap.com and we will check for you.

Npcap OEM utilizes the same SDK as normal Npcap, and that is available from the Npcap public pages.

Support and Documentation for Npcap OEM

Npcap OEM shares its documentation with the public/demo version of Npcap. All of the documentation (and even the source code) is available by hyperlink from the Npcap public pages.

Licensees with an active maintenance (support and updates) subscriptions have special access to report bugs or ask Npcap technical support questions. If you are a licensee and don't have the support contact information, please email sales@nmap.com and we will send it to you.

FAQ - Frequently Asked Npcap OEM Questions

  1. Is maintenance (support and updates) optional?

    Maintenance is optional but highly recommended because it extends the perpetual license to include all new versions released during the maintenance period. And Npcap is under very active development with dozens of feature enhancements, bug fixes, and performance improvements made every year. Maintenance also includes commercial support whenever you need it.

  2. Is the first year of maintenance included in the license fee?

    No. Customers can decide on their own initial maintenance term. Many choose the 3 or 5-year terms for the discounted price and to avoid the hassle of annual renewals. Others decline maintenance entirely. Quoting the license and maintenance fees separately allows customers to make their own selections.

  3. Do you sell through resellers?

    Yes, we are happy to sell through your preferred reseller. We regularly work with SoftwareONE, SHI International, and dozens of others. Just ask your reseller to contact sales@nmap.com on your behalf with the information requested in Purchase Process.

  4. What if Npcap OEM doesn't work out for us? Do you have a trial license or a way to return it for a refund?

    Our internal license certificate (Section 5.4) includes a 3-month period from the software delivery date during which you can cease using Npcap OEM and request a full refund for any reason. Refunds include any maintenance fees already paid as well as any license fees, and they are provided within 30 days. So you don't lose a penny if you aren't happy with Npcap OEM or don't end up needing it.

    We also offer the free/demo version of Npcap for download and testing. While this lacks some convenience features of Npcap OEM (such as the silent installer), the actual driver functionality is virtually identical. This allows you to perform initial functionality testing even before purchasing a license.

  5. Is Npcap OEM free if only used with Wireshark, Nmap, etc.

    We do offer the free/demo version of Npcap, which is free when only used with Wireshark, Nmap, and/or Microsoft Defender for Identity. Up to 5 copies of the free version may also be used with other software.

    Npcap OEM is commercial software that provides many benefits even to companies that only use it with Wireshark or Nmap. The silent installer (/S) allows you to automate Wireshark and Nmap deployments and upgrades. Npcap OEM also includes commercial support whenever you need it. Be sure to purchase the license size (100, 250, 500, or unlimited installs) which factors in all of your intended usage, including Nmap, Wireshark, and MS Defender for Identity.

  6. Where is the Npcap OEM SDK?

    There is no need for a separate Npcap OEM SDK because all software compiled with the normal Npcap SDK is 100% compatible with both the free/demo Npcap and Npcap OEM. Download the Npcap SDK here. Please keep in mind that this internal-use license is not for redistribution. If you are compiling software that you will be distributing with Npcap outside of your organization, please buy the Npcap OEM redistribution license instead.
