How do ESPs share threat indicators internally?

Centralized detection: **ESP**-wide monitoring identifies threats from any customer, sharing protection across the platform. One customer's **phishing** attempt triggers blocking for all.

Pattern sharing: techniques and indicators from detected threats inform platform-wide filtering. Abuse team learnings become automated rules protecting everyone.

Customer notification: when threats affect specific customers (compromise, targeting), ESPs notify and assist. Internal intelligence supports customer security, not just platform protection.
