Use AVAST/Zscaler Enterprise Cloud Inspection
The Cloud Hosted Firewall Engine with Unlimited Horsepower
The AVAST Secure Internet Gateway solutions can inspect https/SSL traffic for all of your users, on all of their devices, no matter what your Internet bandwidth, or how many locations you have.
With this gateway solution in the Cloud, all encrypted traffic is inspected, at one central way-point on the Internet.
Don't be limited by what is "behind" or "outside" of your firewall!
Have everything, and everyone, from anywhere, go THROUGH your firewall.
Corporate users, assets, and potential liabilities may have moved outside of your traditional security zone, but your need to maintain security policies, enforce usage and content rules, and have the availability of real-time reporting and monitoring has not.
