The Challenge

Many M365 customers eliminate the Secure Email Gateway (SEG) and add Exchange Online Protection with M365's Advanced Threat Protection to stop spam, malware, and viruses. But this still leaves organizations vulnerable to sophisticated email attacks that leverage impersonation.

These organizations need a layer of defense that is easy to implement, cost-effective, and more efficient.

The Agari Solution

Agari adds leverages data science to complement the existing security controls within M365. In fact, two-thirds of Agari customers who deploy M365 with Fortra's Cloud Email Protection do so without a SEG.

This approach is delivered via API in the cloud and blocks identity deception attacks to deliver better security, reduced costs, and improved business agility.

Benefits of Agari with Microsoft 365

Advanced Data Science

Fortra's Advanced Email Security uses machine learning, large language models (LLMs), and neural networks to evaluate email legitimacy.

Cloud-Native Architecture

Agari's cloud-native architecture allows for seamless integration with Exchange Online and Azure Active Directory.

Advanced Analytics

Intuitive executive dashboard allows you to quantify the value of protecting Microsoft 365 with Agari.

Other Email Environments

Agari works within cloud, on-premise, and hybrid environments.


Microsoft Exchange paired with a Secure Email Gateway (SEG) is the dominant email configuration for on-premise deployments. Agari works alongside the SEG to protect against advanced email attacks, such as executive spoofing and vendor impersonation. 


Adoption of Google Workspace continues to grow especially with small and medium-sized organizations. Agari is a cost-effective way to secure your deployment to protect against the most damaging and costly advanced email attacks.
