Armorblox Stops Today’s Unwanted Email Communications

Graymail, even if not malicious, is a nuisance to both end users and security teams, especially to executives within an organization who receive a disproportionate share of these unwanted emails. One of the main challenges is the high volume of email communications coming into the organization as well as being reported by end users – wasting valuable time with manual sorting and deletion across the organization.
