Proofpoint Dynamic Email Reputation Key Capabilities:

  • Multi-layered protection with global and local email sender IP reputation: Leveraging visibility into the industry's largest volume of email per day, global email IP reputation management ensures defense against email sender's IP addresses as soon as they appear.
