Active Defense and Extended Protection for Microsoft 365 Users

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

Why Native Microsoft 365 Security Isn’t Enough

While Microsoft 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 Microsoft 365.

  • Managed by Trustwave SpiderLabs Email Security Research and Malware Analysis Team

Better Together – Microsoft 365 and Trustwave MailMarshal Cloud

Microsoft 365 detects spam, and malspam to a much lesser extent when compared to the detection rates generated by Trustwave MailMarshal. Suspicious emails detected by Microsoft 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 MailMarshal with the built-in security protections in Microsoft 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 Microsoft 365 E3 or E5 license subscriptions.
