About Avanan

The Cloud Security Platform

What We Do

We secure all your cloud email, messaging, and file sharing tools from phishing, malware, data loss, and more in a single click.

Our Mission

To redefine the way you compare, deploy, and manage security in the cloud.

It all started when our founders, working for one of the most successful network security companies at that time, were frequently asked by customers how they should implement the same type of security in the cloud. This prompted the realization that the best security technologies for malware detection, data classification, encryption, user management, access control, and so much more already existed. Unfortunately, customers had no way to connect it to their SaaS applications in a unified way, with just a single click.

With that vision in mind, Avanan cloudified the security tools of the industry's leading vendors and built a platform that could connect these tools to the most widely used enterprise SaaS applications. With everything virtualized, installing these tools on any SaaS is as easy as installing an app on a phone. By simply choosing the security tools from the Avanan security app store, customers can implement multiple security solutions across any or all of their SaaS applications.
