Integration checklist
- Bidirectional ticket / alert sync
One-way alert push only — closing the ticket does not clear the alert.
- Asset / device mapping
Devices match to client records automatically after the initial mapping pass.
- Alert escalation rules
Escalation logic has to live in one system; expect duplicated rule sets.
- Billing reconciliation
Neither product owns billing — reconcile through your billing/PSA layer.
- Webhook / event support
Polling required — API grades C and A limit real-time events.
Common bottlenecks & caveats
- Sync depth is partial — budget technician time or an automation platform such as Rewst.
- API rate limits on Proofpoint Essentials cause sync lag on tenants above ~1,000 endpoints.
- Seat minimums apply (Proofpoint Essentials: 25, HaloPSA: 1) — small tenants pay for unused units.
- Field mapping is not retroactive: records created before the integration is enabled usually need a one-time backfill.
