Email was born to flow

Tired of monolithic, one-size-fits-all email security gateways (SEGs) that force compromises? Or email content filters that are slow to respond and lacking in accuracy? Legacy solutions are inflexible, slow to adapt, and often leave you paying for features you don't need while lacking the specific defenses you do. In today's threat landscape, that rigidity is a critical vulnerability.
