Pricing and Plans

Sadly, Device42 has opaque pricing. To request a custom quote, you need to enter your first name, last name, and email address. Also, Device42 offers an annual subscription model based on the number of devices—the more you discover, monitor, and manage, the more you’ll pay.

In our opinion, the pay-per-pricing model can make Device42 expensive. In fact, a user on Reddit mentioned you need to be ready to pay around £50,000 a year for using Device42, which may not be affordable for all:
