  • How can I increase the usage of my subscription?

    Defender paid Professional and Enterprise subscriptions offer a pay-as-you-go model in addition to the included quotas. Once you can exceed your quota, you will be invoiced according to the additional metered usage at the end of each monthly billing cycle.

  • How much will I pay if I exceed the included quota of my subscription?

    If you subscribe to our Professional or Enterprise subscriptions and use the pay-as-you-go model, you may exceed your included quota and be invoiced at the end of the monthly billing cycle based on your actual usage. The amount will depend on the features you use.
  • When do monthly quotas reset?

    The usage monthly quotas will reset back to 0 on the 1st of each calendar month.

    Depending on your subscription plan, for your Defender subscription, you will either be billed monthly or annually. Metered overages that exceed your included quota will be billed monthly regardless of your subscription plan.
  • Which payment methods are supported?

    You can pay for your Defender subscription using Credit Card, wire transfer, and USDC. Using the pay-as-you-go model will require you to add your credit card details even if you choose a different payment method to pay for your subscription.
  • How can I cancel my subscription?

    To submit a request to cancel your subscription, navigate to the subscriptions page in your account and select to downgrade to the Builder subscription. Note that the changes to the subscription will be applied in your next billing cycle.
