Choose Immune when

Public and shared inboxes are the pain

  • A few shared inboxes create most of the noise and risk.
  • You want verification, not another dashboard of spam scores.
  • Pricing should follow protected addresses, not headcount.

Barracuda may still fit when

You need something else

  • You want backup, archiving, or awareness training in the same email vendor.
  • Every employee mailbox must sit behind the same gateway.
