The challenge of network-centric security

For 30 years, enterprises have relied on network-centric methods to connect users to the network, and by extension the applications running on it. But the way users work has changed, and with applications moving to cloud, the perimeter has extended to the internet. This renders network-centric solutions, like remote access VPNs, obsolete.

Common pitfalls of network-centric approaches:
  • Places users on-net which increases risk
  • Provides a poor end user experience
  • Inbound connections create opportunity for DDoS attacks
  • Requires appliances, ACLs and FW policies
  • No ability to provide application segmentation
  • Lack of visibility into app-related activity
Challenges of the remote access VPN

Zscaler Private Access

Enabling user and application-centric security

Zscaler Private Access (ZPA) is a cloud service from Zscaler that provides zero trust, secure remote access to internal applications running on cloud or data center. With ZPA, applications are never exposed to the internet, making them completely invisible to unauthorized users. The service enables the applications to connect to users via inside-out connectivity versus extending the network to them. Users are never placed on the network. It provides a software-defined perimeter that works across any IT environments, any device and any internal application.

Zscaler Private Access Benefits

Justification for making zero trust security part of your cloud transformation.

A better access experience

Users have seamless access across all apps and devices. Uses same Zscaler App as ZIA. Also, browser access is available for web apps.

Never place users on-net

Authorized users have access to applications without the need to access the network, reducing risk.

Segment by application, not network

Micro-tunnels enable network admins to segment by application with no need to segment networks or manage ACLs or FW policies

Inside-out connectivity means app invisibility

Apps connect out to authorized users, and don’t listen for inbound pings. IP addresses are never exposed and DDoS is impossible.

The Internet becomes the new corporate network

Cloud adoption extends the perimeter to the internet. Use TLS-based encrypted tunnels and custom PKI to ensure private apps remain secure.

Fully software-defined perimeter service

The cloud security service ensures scalability across multiple data centers with no need for clunky hardware appliances.

NOV, a 150 year old Oil & Gas company, uses Zscaler Private Access for zero trust access to 7,000 apps for 10,000 users.

Software-defined. Built for zero trust security

Zscaler Private Access takes a user and application-centric approach to network security. It ensures that only authorized users and devices have access to specific internal applications. Rather than relying on physical or virtual appliances, ZPA uses lightweight infrastructure agnostic software to connect both users and applications to the Zscaler Security Cloud, where the brokered connection is stitched together.

ZPA enables enterprises to break free from the remote access VPN-driven
mindset that is centered around the data center
1.  Zscaler Enforcement Node
  • Hosted in cloud
  • Used for authentication
  • Customizable by admins
  • Brokers a secure connection between a Z-App and
    a Z-connector
2.  Zscaler App
  • Mobile client installed on devices
  • Requests access to an app
3.  App Connector
  • Sits in front of apps in Azure, AWS, and other public cloud services
  • Listens for access requests to apps
  • No inbound connections

Discover and secure shadow IT applications

Many enterprise teams are unaware of the sheer number of applications in their environment. ZPA identifies previously undiscovered internal applications running in the datacenter or on public cloud infrastructure. Once identified, admins can set granular policies for each application, ensuring the environment remains secure and controlled. This, combined with ZPA’s ability to make known applications invisible to unauthorized users, reduces the attack surface dramatically.

Choose application segmentation, not network segmentation

In the past admins needed to segment networks to ensure secure user connections. Today, enterprises use ZPA to control which users access which applications. Admins can easily set granular policies at the application level for specific users, users groups, applications, application groups and associated subdomains.

1.  Create and define policy names
2.  Set different permissions levels for users and user groups
3.  Select the applications each policy is associated with
4.  Easily add new rules and policies for your users and applications from within the UI
