Every inbox needs a control tower.
With Email Traffic Control, you decide what lands, what's rerouted, and what never takes off.
Rules promise safety.
What they really deliver is chaos.
Rules Don't Adapt
Email moves fast. Rules stay frozen.
Rules Break
One small change can take down an entire domain.
Rules Conflict
Fixing one problem often creates two more.
Rules Multiply
Every client adds another layer to manage.
This is what control actually looks like.
Built into Shield, Email Traffic Control (ETC) replaces black-and-white rule logic with flexible workflows designed for the gray areas where traditional email security breaks down. Ready-to-use templates cover the most common scenarios or just point and click to build your own.
Intelligent Data Detectors
Built-in detectors trained to recognize entire categories of sensitive and risky messages automatically.
No-Code Workflow Builder
Point-and-click workflow builder that replaces manual rule building and maintenance with one-time decisions.
Template Library
Ready-to-use templates for common scenarios, so MSPs can quickly apply them across multiple client environments with ease.
ETC in the field
"We've barely scratched the surface with Email Traffic Control and it's already delivering real value. PHI compliance is now automatic for our medical records staff, and we're planning to expand to public health law compliance, trusted sender controls, and custom workflows for individual client needs. Our job is to make sure healthcare staff can focus on taking care of their patients. The more we can protect them without them having to think about it, the better."
