Struggling to stop Advanced Threats?
It’s time for a new approach.

Zscaler takes Advanced Threat Protection to a whole new level.

Today’s Advanced Threat Protection is a story of compromise

Hackers exploit appliance limitations

Trusted websites and AWS servers often are not inspected by appliances because it is viewed as “trusted” and inspecting it would overwhelm appliances.

Zero-day protection is stuck in the Data Center

Sandboxing protection is essential for Advanced threat protection, however today’s solutions are expensive and stuck in the data center. When your users leave the network, your sandbox appliance can’t protect them.

The SSL Challenge: Finding what you can’t see

Most organization compromise on inspecting SSL traffic due to budget and performance limitations. The problem is over half of todays malware is now delivered over encrypted SSL traffic.

Relying on UTM and NGFW appliances to secure internet traffic is costly, results in appliance sprawl, and compromises branch security.
