Secure Email Gateway

Active Defense and Extended Protection for Office 365 Users

Defenders need to be right every single time. Attackers, on the other hand, need to be right just once.

Why Native Office 365 Security Isn’t Enough

While Office 365 is a robust service offering, it misses significant phishing, malware and business email compromise attacks. And, while email security add-ons like Exchange Online Protection (EOP) or Advanced Threat Protection (ATP) have fairly good basic spam and malware filters, they will not reliably stop malicious spam or your end-users from gaining access to malicious emails haphazardly dumped into their Junk email folder by Office 365.

Better Together – Office 365 and Trustwave Secure Email Gateway

Office 365 detects spam, and malspam to a much lesser extent when compared to the detection rates generated by Trustwave Secure Email Gateway. Suspicious emails detected by Office 365 are not quarantined from end user access giving cyber attackers, through their targeted victims, an extended opportunity to unleash malicious code into a computer network.

Conversely, combining the proprietary defense filters in Trustwave Secure Email Gateway with the built-in security protections in Office 365 delivers unprecedented detection and extended protection in real time 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, per year cost considerably less than upgrading to Office 365 E3 or E5 license subscriptions.
