That suits a team that wants a human check rather than a silent block, on Microsoft 365, Google Workspace or Exchange. INKY changed owners recently, so ask how the product will be sold and supported from here.

Because it runs on several mail platforms, it also covers mixed setups. Check how people outside your company experience the one-click decrypt and the extra verification step before you roll it out.
