What is a Preview License?
Every account created with nTop has a free preview license. You can check all your available licenses from User Dashboard (app.ntop.com) > Account Settings. Preview mode is a mode of nTop that we introduced to give users the opportunity to experience the power and capabilities of nTop without purchasing a full license. Note: If you had a license before that expired, you would automatically be switched to a Preview License.
What can you do in Preview Mode?
Once you log into nTop, you’ll be greeted by our Home screen, which provides exciting example files and learning resources. You can also open existing files from this Home screen.
- Preview nTop Notebooks and experience the power of reusable workflows.
