To benefit from cloud apps, break free from network security appliances and go direct

Securely embracing the cloud and delivering a fast user experience requires local internet breakouts. But, securing internet traffic with traditional UTM and NGFW appliances requires deploying stacks of security appliances in all locations, which is cost prohibitive and extremely difficult to manage.

UTM/NGFW appliance sprawl
  • Cost prohibitive to deploy
  • Creates appliance sprawl
  • Untenable to manage
  • Compromises branch security
  • Performance degrades with SSL inspection and cloud apps with long-lived connections

Cloud Firewall Solution

Zscaler enables secure local breakouts – without appliances

Zscaler Cloud Firewall enables fast and secure local internet breakouts for all ports and protocols, without appliances. Cloud Firewall scales elastically to handle all your cloud application traffic, and is an integral part of the Zscaler Cloud Security Platform, which brings the entire security stack closer to the user to ensure identical protection no matter where they connect.

More powerful than a next-generation firewall

Proxy-based
architecture

Dynamically inspects traffic for all users, applications, devices, and locations. Natively inspects SSL/TLS traffic—at scale—to detect malware hidden in encrypted traffic. And, enables granular firewall policies spanning multiple layers based upon network app, cloud app, domain name (FQDN), and URL.

Learn why a proxy-based architecture is required to stop today's advanced threats.

Cloud IPS

Delivers always-on IPS threat protection and coverage, regardless of connection type or location. Inspects all user traffic on and off network, even hard-to-inspect SSL traffic, to restore full visibility into user, app, and internet connections.

Learn how Zscaler Cloud IPS takes intrusion prevention to a higher level.

DNS security and control

Protects users from reaching malicious domains as the first line of defense. Optimizes DNS resolution to provide a better user experience and cloud application performance, which is especially critical for CDN-based apps. And, provides granular controls to detect and prevent DNS tunneling.

Visibility and simplified management

Delivers real-time visibility, control, and immediate policy enforcement across the platform. Logs every session in detail. Uses advanced analytics to correlate events and provide insights into threats and vulnerabilities for all users, applications, and locations from a single console.

The next-generation firewalls (NGFWs) in use today were architected over a decade ago. But, providing security and access controls for the cloud-first enterprise requires dynamic capabilities that NGFWs were not designed to deliver. Explore how Zscaler Cloud Firewall capabilities surpass those of NGFWs or virtualized appliances.
