# New sign-up limits in Clerk Protect

The [Business plan](https://clerk.com/pricing) now includes two more advanced protections in [Clerk Protect](https://clerk.com/docs/guides/protect/overview.md) to help limit bulk account creation:

- [**Limit sign-ups per email domain**](https://clerk.com/docs/guides/protect/protections/limit-sign-ups-per-email-domain.md) to cap sign-ups from one email domain in an hour.
- [**Limit sign-ups from shared infrastructure**](https://clerk.com/docs/guides/protect/protections/limit-sign-ups-from-shared-infrastructure.md) to cap bursts of sign-ups that appear to use the same infrastructure.

Both limits apply across IP addresses and complement the existing [per-IP sign-up limit](https://clerk.com/docs/guides/protect/protections/limit-sign-ups-per-ip-address.md).
