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
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.Read the Solution Brief
Zscaler Private Access benefits
Transform with Zscaler.
Users receive better experience
Integrates with SSO and provides seamless direct-to-app remote user experience.
Less complexity for admins
Network admins can segment based on application from within the web UI. No need to segment by network. No IP address segmentation or access control lists required.
Secure remote access, without network access
Policy based access to apps, with no access to network. Visibility into apps being accessed by users and ability to discover and secure unsanctioned apps
Traffic remains private via internet network
Service uses dynamic, application specific TLS-based end to end encrypted tunnels. Enterprises can bring their own PKI as well.
No hardware appliances, lower costs
The cloud service requires no hardware. Enterprises can easily scale across multiple data centers with no need to purchase new appliances.
Scale elastically, reduce latency
The service uses the global Zscaler cloud to ramp up new users and route them to the app location nearest to them, leveraging a vast cloud network across multiple continents.
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.
