Zscaler Web Security

A complete secure internet gateway solution delivered as a service.

Today’s web security model is broken

The broken perimeter

Your users are mobile and are no longer behind your appliance security stack. They connect straight to the cloud, where their applications live.

The internet is now their corporate network, so what is your security perimeter protecting?

The cost of an old architecture

Using a hub-and-spoke network for security isn’t cost-effective. Moving apps to the cloud has emptied the data center, leaving behind a maze of expensive appliances with nothing to protect.

Why continue to backhaul traffic and pay for an architecture that isn’t cloud ready?

a diagram showing despite massive appliance investments, breaches continue. 90's internet gateway design has lost its effectiveness.

The breaches continue

Even Web security products in your gateway are missing attacks. Zero-days attacks, botnets, threats hiding in SSL traffic, and others need a fully integrated approach that can scale.

With increasing inspection demands, can your appliances keep up?

Zscaler Web Security: A new approach to user protection

Zscaler Web Security, part of the Zscaler Cloud Security Platform, delivers the complete security stack as a cloud service, eliminating the cost and complexity of traditional secure web gateway approaches.
