Zero Trust Network Access with Zscaler Private Access (ZPA)
Secure, seamless private app access for every user, device, and location - powered by the world's most deployed ZTNA solution.
---
Overview
Traditional VPN-based remote access was built for a different era. Today's hybrid workforce demands something better - faster connections, stronger security, and far less administrative complexity. Zscaler Private Access (ZPA) delivers all three through a cloud-native Zero Trust Network Access (ZTNA) architecture that connects users directly to applications without ever exposing your network or your apps to the public internet.
As an authorised Zscaler partner, TechPower helps enterprise IT teams deploy, configure, and optimise ZPA to replace legacy infrastructure and build a modern, scalable security posture.

The Problem with Legacy VPN
VPNs were not designed for today's threat landscape or workforce expectations. The numbers tell the story:
- 91% of organisations report concerns that VPNs are compromising their security
- 56% experienced at least one VPN-related attack in 2023-2024
- 54% of VPN-related breaches involve lateral movement across the network
When a VPN user is compromised, attackers gain broad network access - not just access to a single application. That is the fundamental flaw ZTNA is designed to fix.

What is Zscaler Private Access (ZPA)?
ZPA is a cloud-delivered ZTNA platform that creates direct, one-to-one encrypted connections between authenticated users and specific applications. Users never join the corporate network, and applications are never exposed to the internet. Access is granted based on identity, device posture, and contextual policy - not network location.
ZPA is built on the Zscaler Zero Trust Exchange, the world's largest security cloud, and can replace VPN and VDI infrastructure in hours, not months.

Use Cases
VPN Replacement
Retire legacy VPN infrastructure and deliver faster, more secure access to data centre and cloud applications - without the complexity of managing network segmentation rules.
Hybrid Workforce Enablement
Give remote employees and in-office staff a consistent, high-performance access experience regardless of where they are working.
Third-Party and Contractor Access
Extend secure, agentless access to suppliers, vendors, and contractors on unmanaged or BYOD devices - without granting them broad network access.
VDI Modernisation
Replace slow, costly virtual desktop infrastructure with direct app access that delivers a faster, smoother experience while maintaining strong data security on unmanaged devices.
OT and Industrial IoT Access
Enable secure remote access to operational technology and industrial IoT systems, simplifying remote maintenance without bridging IT and OT networks.
App-to-App Segmentation
Minimise lateral movement risk by enforcing identity-based authentication and access policies at the application layer, not the network layer.

Proven at Enterprise Scale
Organisations across industries have standardised on ZPA to transform secure access:
- PTC eliminated its legacy VPN entirely, placing all internal resources behind ZPA for 7,000 employees across 30 countries
- Siemens AG extended secure OT remote access at a scale that would have taken weeks with legacy VPN tools
- Royal Caribbean enabled secure, seamless access for employees working from ships, airports, hotels, and offices worldwide
- State of Oklahoma accelerated private application access by up to 600% compared to their previous VPN environment
