In a world of cloud and mobility, network
security is essentially worthless.
With apps in the cloud and users connecting from
everywhere, what’s left for your network security to protect?
It’s time to rethink network security
Networks were designed to connect users to apps in the data center and we built a secure perimeter around the network to keep those users and apps safe from the outside. But with apps moving to the cloud, and users connecting from everywhere, the perimeter is gone. It’s time to decouple security from the network and use policies that are enforced anywhere apps reside and everywhere users connect.
The world has changed. So why is security still anchored to the data center?
The Old World
On-premises data center
Hub-and-spoke: backhaul traffic to the on-premises data center
Castle-and-moat: to secure the corporate network
The New World
Public cloud, SaaS
Direct-to-cloud traffic routed locally to the internet
Securely connect users and devices to applications regardless of network
To secure the new world, flip the security model
In the past, you had to be on the network to get security protections. But by moving security off the network and into the cloud, you put the full stack of network security engines everywhere your users go. Because security protections are applied consistently, you have the exact same protections in a branch office, at home, or in an airport as you have in the HQ.
Move from a network-centric security model to a user-centric approach for fast, consistent policy enforcement
