The authorization layer for every data request, human or agent
Define access rules in plain language, and Immuta compiles them into native controls inside your data infrastructure.
The policy engine returns allow, mask, filter, deny or escalate for every request in under a second, at enterprise scale.
Route genuine exceptions to data owners with the purpose attached, while routine access resolves on its own.
Give humans and AI agents just-in-time, scoped permissions so assistants only reach the data their task needs.

Collaborative inbox and email management for teams
Let multiple people work the same inbox with clear assignment, internal statuses, and visibility into who is answering what.
Discuss and prepare replies inside the email thread itself, so context stays attached and nobody is left out of the loop.
Turn any email into an assigned task and see what each teammate is working on today, tomorrow, and next week.
Automate repetitive routing, tagging, and follow-up with rules, rule templates, and workflow automations.
