Layering Secure Email Gateway with Office 365 or other web-based email gateways

Email security add-ons like Exchange Online Protection (EOP) or Advanced Threat Protection (ATP) are somewhat effective at blocking massive spam and known threats, but they will not reliably stop highly targeted business email compromise, phishing, spear phishing or zero-day attacks.
Layering Secure Email Gateway with your Office 365 or other web-based email gateways delivers advanced protection from ordinary to sophisticated attacks by proactively detecting suspicious email, removing them from end user access and shielding well-intentioned end users from falling prey to known and targeted attacks – all at a per user cost far less than an E5 license subscription.
