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?


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.


Always-on security

Delivery from the cloud lets you restore your security perimeter by providing always-on security that follows the user, regardless of location.


A cloud-enabled architecture

Built in the cloud and delivered as a service, you can easily deploy in minutes and minimize costly appliances and backhauling.

The ultimate security stack

With multiple inspection technologies, you get a fully integrated security stack with full SSL inspection that never runs out of capacity.
